Objective: To introduce capped biparametric (bp) MRI slots for follow-up imaging of prostate cancer patients enrolled in active surveillance (AS) and evaluate the effect on weekly variation in the number of AS cases and total MRI workload. Methods: Three 20 min bpMRI AS slots on two separate days were introduced at Addenbrooke’s Hospital, Cambridge. The weekly numbers of total prostate MRIs and AS cases recorded 15 months before and after the change (Groups 1 and 2, respectively). An intergroup variation in the weekly scan numbers was assessed using the coefficient of variance (CV) and mean absolute deviation; the Mann–Whitney U test was used for an intergroup comparison of the latter. Results: In AS patients, a shift from considerable to moderate variation in weekly scan numbers was observed between the two groups (CV, 51.7 and 26.8%, respectively); mean absolute deviation of AS scans also demonstrated a significant decrease in Group 2 (1.28 vs 2.58 in Group 1; p < 0.001). No significant changes in the variation in total prostate MRIs were observed, despite a 10% increased workload in Group 2. Conclusion: A significant reduction in weekly variation of AS cases was demonstrated following the introduction of capped bpMRI slots, which can be used for more accurate long-term planning of MRI workload. Advances in knowledge: The paper illustrates the potential of introducing capped AS MRI slots using a bp protocol to reduce weekly variation in demand and allow for optimising workflow, which will be increasingly important as the demands on radiology departments increase worldwide.

e16071 Background: To report long term Health Related Quality of Life (HRQoL) in a prospective series of 629 patients with intermediate or high-risk clinically localized prostate cancer treated with either IMRT or IMRT + HDR. Methods: Between December 1999 and December 2010, 629 patients (pts) with PSA›10, Gleason score›6 and/or T2b-T3 N0 M0 prostate cancer entered the study. Pts were prospectively assigned to one of the two treatment groups: 76 Gy HD-3D-IMRT to the prostate in 38 fractions (group 1; 315 patients) or 46 Gy LD-3D-CRT+ 16 Gy HDR-B given in 2 fractions of 8 Gy (group 2, 316 patients), limiting the maximum rectal dose to 85% of the prescribed dose. Both groups were well balanced taking into account patient’s as well as tumors’ characteristics. Toxicities were scored by the EORTC /RTOG morbidity grading scales. Special attention to local, regional or distant recurrence, survival, late effects, PSA and testosterone levels as well as HRQOL was done. Results: All pts completed treatment. None pts included in group 1 or 2 had grade 3 or more rectal toxicity. With a mean follow-up of 96 m, the 8-year free-from-failure survival was 90.7% and 98.3% (p<0.02) in group 1 and 2 respectively; free-from-metastases survival 96.9% and 97.9% (p<0,08)for group 1 and 2; and cause-specific survival 97.4% and 98.3% (p<0.09). HRQoL was evaluated before treatment, at 3 months interval during the first year follow up and in a yearly basis until 10-year. I-PSS and EORTC’s QLQ-C30 with PR-25 were used. I-PSS scores at 1, 3 and 6 months and at 1, 2, 3, 5 and 8 years follow-up were 6.39, 5.00, 2.52, 2.21, 2.35, 3.65 and 1.43 for group 1 pts and 1.50, 1.10, 1.01, 1.05, 0.89, 0.66, 0.67 for group 2 pts. Global HRQoL scores at 1, 3 and 6 months and at 1, 2, 3 and 5 years follow up were 5.56, 5.75, 5.33, 6.00, 5.40, 5.58 and 5.11 for group 1 pts and 5.60, 6.40, 5.78, 5.89, 5.83, 6.37, 6.00 for group 2 pts, being found to be statistically significant at 3 and 5 years follow up (p<0,001 and p<0,024). Conclusions: High-dose 3D-IMRT + HDR brachytherapy was found to be a method of escalating the dose to the prostate that not only increased the chances of cure for patients if not increased their long-term Health Related Quality of Life.

<b><i>Background and Purpose:</i></b> Hemodynamic evaluation of moyamoya patients is crucial to decide the treatment strategy. Recently, CO<sub>2</sub>-triggered BOLD MRI has been shown to be a promising tool for the hemodynamic evaluation of moyamoya patients. However, the longitudinal reliability of this technique in follow-up examinations is unknown. This study aims to analyze longitudinal follow-up data of CO<sub>2</sub>-triggered BOLD MRI to prove the reliability of this technique for long-term control examinations in moyamoya patients. <b><i>Methods:</i></b> Longitudinal CO<sub>2</sub> BOLD MRI follow-up examinations of moyamoya patients with and without surgical revascularization have been analyzed for all 6 vascular territories retrospectively. If revascularization was performed, any directly (by the disease or the bypass) or indirectly (due to change of collateral flow after revascularization) affected territory was excluded based on angiography findings (group 1). In patients without surgical revascularization between the MRI examinations, all territories were analyzed (group 2). <b><i>Results:</i></b> Eighteen moyamoya patients with 39 CO<sub>2</sub> BOLD MRI examinations fulfilled the inclusion criteria. The median follow-up between the 2 examinations was 12 months (range 4–29 months). For 106 vascular territories analyzed in group 1, the intraclass correlation coefficient was 0.784, <i>p</i> &#x3c; 0.001, and for group 2 (84 territories), it was 0.899, <i>p</i> &#x3c; 0.001. Within the total follow-up duration of 140 patient months, none of the patients experienced a new stroke. <b><i>Conclusions:</i></b> CO<sub>2</sub> BOLD MRI is a promising tool for mid- and long-term follow-up examinations of cerebral hemodynamics in moyamoya patients. Systematic prospective evaluation is required prior to making it a routine examination.

Proximal tibiofibular dislocation in closing-wedge high tibial osteotomy increases the risk of medium and long-term total knee replacement. Background: High tibial osteotomy is an effective treatment for medial osteoarthritis in young patients with varus knee. The lateral closing-wedge high tibial osteotomy (CWHTO) may be managed with tibiofibular dislocation (TFJD) or a fibular head osteotomy (FHO). TFJD may lead to lateral knee instability and thereby affect mid- and long-term outcomes. It also brings the osteotomy survival rate down. Objective: To compare the CWHTO survival rate in function of tibiofibular joint management with TFJD or FHO, and to determine whether medium and long-term clinical outcomes are different between the two procedures. Material & Methods: A retrospective cohort study was carried out that included CWHTO performed between January 2005 to December 2018. Those patients were placed in either group 1 (FHO) or Group 2 (TFJD). Full-leg weight-bearing radiographs were studied preoperatively, one year after surgery and at final follow-up to assess the femorotibial angle (FTA). The Rosenberg view was used to assess the Ahlbäck grade. The Knee Society Score (KSS) was used to assess clinical outcomes and a Likert scale for patient satisfaction. The total knee replacement (TKR) was considered the end of the follow-up and the point was to analyze the CWHTO survival rate. A sub-analysis of both cohorts was performed in patients who had not been FTA overcorrected after surgery (postoperative FTA ≤ 180°, continuous loading in varus). Results: A total of 230 knees were analyzed. The follow-up period ranged from 24–180 months. Group 1 (FHO) consisted of 105 knees and group 2 (TFJD) had 125. No preoperative differences were observed in terms of age, gender, the KSS, FTA or the Ahlbäck scale; neither were there any differences relative to postop complications. The final follow-up FTA was 178.7° (SD 4.9) in group 1 and 179.5° (SD 4.2) in group 2 (p = 0.11). The Ahlbäck was 2.21 (SD 0.5) in group 1 and 2.55 (SD 0.5) in group 2 (p = 0.02) at the final follow-up. The final KSS knee values were similar for group 1 (86.5 ± 15.9) and group 2 (84.3 ± 15.8). Although a non-significant trend of decreased HTO survival in the TFJD group was found (p = 0.06) in the sub-analysis of non-overcorrected knees, which consisted of 52 patients from group 1 (FHO) and 58 from group 2 (TFJD), 12.8% of the patients required TKR with a mean of 88.8 months in group 1 compared to 26.8% with a mean of 54.9 months in the case of group 2 (p = 0.005). However, there were no differences in clinical and radiological outcomes. Conclusion: TFJD associated with CWHTO shows an increase in the conversion to TKR at medium and long-term follow-up with lower osteotomy survival than the CWHTO associated with FHO, especially in patients with a postoperative FTA ≤ 180° (non-overcorrected). There were no differences in clinical, radiological or satisfaction results in patients who did not require TKR. Level of evidence III. Retrospective cohort study.

The immediate and long-term outcomes, complications, recurrences and the need for retreatment were analyzed in a series of 280 consecutive patients with anterior communicating artery aneurysms treated with the endovascular technique. From October 1992 to October 2001 280 patients with 282 anterior communicating artery aneurysms were addressed to our center. For the analysis, the population was divided into two major groups: group 1, comprising 239 (85%) patients with ruptured aneurysms and group 2 comprising of 42 (15%) patients with unruptured aneurysms. In group 1, 185 (77.4%) patients had a good initial pre-treatment Hunt and Hess grade of I-III. Aneurysm size was divided into three categories according to the larger diameter: less than 4 mm, between 4 and 10 mm and larger than 10 mm. The sizes of aneurysms in groups 1 and 2 were identical but a less favorable neck to depth ratio of 0.5 was more frequent in group 2. Endovascular treatment was finally performed in 234 patients in group 1 and 34 patients in group 2. Complete obliteration was more frequently obtained in group 2 unlike a residual neck or opacification of the sac that were more frequently seen in group 1. No peri-treatment complications were recorded in group 2. In group 1 the peri-treatment mortality and overall peri-treatment morbidity were 5.1% and 8.1% respectively. Eight patients (3.4%) in group 1 presented early post treatment rebleeding with a mortality of 88%. The mean time to follow-up was 3.09 years. In group 1, 51 (21.7%) recurrences occurred of which 14 were minor and 37 major. In group 2, eight (23.5%) recurrences occurred, five minor and three major. Two patients (0.8%) presented late rebleeding in group 1. Twenty-seven second endovascular retreatments were performed, 24 (10.2%) in group 1 and three (8.8%) in group 2, seven third endovascular retreatments and two surgical clippings in group 1 only. There was no additional morbidity related to retreatments. Endovascular treatment is an effective method for the treatment of anterior communicating artery aneurysms allowing late rebleeding prevention. Peri-treatment rebleeding warrants caution in anticoagulation management. This is a single center experience and the follow-up period is limited. Patients should be followed-up in the long-term as recurrences may occur and warrant additional treatment.

Purpose. To evaluate the efficacy and safety of femtolaser-assisted phacoemulsification in glaucomatous eyes in the long-term follow-up. Materials and methods. A retrospective analysis of the results of the surgical treatment of patients with combined cataract and glaucoma pathology was analyzed. The patients were divided into groups depending on the method of surgical intervention: 1) phacoemulsification with femtolaser support (26 eyes, 23 patients); 2) phacoemulsification (36 eyes, 30 patients); Results. Before surgery, there were no statistically significant differences in IOP and corneal hysteresis (СН) between groups 1 and 2. The mean values of IOP cc, IOP g and СН of group 1 before surgery were 22.7±6.1 mm Hg, 20.9±6.9 mm Hg, 8.5±1.6 mm Hg; 2 group – 22.9±8.7 mm Hg, 21.6±8.9 mm Hg, 8.9±1.6 mm Hg respectively. Average values of IOP cc, IOP g and CН 5 years after the surgical treatment in group 1 were 15.3±1.2 mm Hg, 14.4±3.4 mm Hg, 9.6±4.2 mm Hg; in group 2 – 18.0±4.2 mm Hg, 16.1±4.2 mm Hg, 8.8±2.2 mm Hg respectively. In both groups, stabilization of IOP and CH indices was noted, which remained throughout the entire observation period, which shows the normalization of the biomechanical properties of the corneoscleral membrane of the eye in the long-term postoperative period. Conclusion. Femtolaser accompaniment of phacoemulsification is an effective and safe method of cataract surgery for combined pathology. Key words: femtolaser, cataract, glaucoma, phacoemulsification.

Introduction: It is currently debated whether cardiac resynchronization therapy (CRT) has an effect on the burden of ventricular arrhythmias (VA). We investigated whether the reverse remodeling after CRT may reduce the occurrence of VA. Methods : The study included 398 patients enrolled in the InSync ICD Italian Registry, treated with CRT-D and with a follow-up of at least 12 months. Spontaneous VA detected by the device were reviewed and validated. Results: After 6 months of follow-up no VA episodes occurred in 319 patients (group 1), while VA episodes persisted in the remaining 79 (group 2). At baseline, clinical and echocardiographic characteristics of the two groups were comparable: NYHA class (2.9±0.6 vs. 3.0±0.7), QRS width (166±31ms vs. 163±34ms), ejection fraction (26±7% vs. 26±6%), LVEDV (251±98ml vs. 226±45ml), LVESV (182±84ml vs. 158±38ml) (All p=NS). At 6 month visit, ventricular remodeling was apparent only in group 2 pts: LVEDV (200±83ml, p=0.042 vs. Baseline), LVESV (133±65ml, p=0.002 vs. Baseline). No changes were evident in group 2 pts: LVEDV (216±69ml, p=0.769 vs. Baseline), LVESV (160±59ml, p=0.521 vs. Baseline). The long-term survival from all-cause death resulted higher in group 1 pts (Log-rank test: p=0.032). (Figure ) Conclusions: In patients treated with CRT, a reduction of ventricular arrhythmic events occurs during the initial 12 months following implant and is correlated with the degree of ventricular remodeling induced by the therapy. Patients demonstrating the remission of arrhythmic episodes will have better survival and more pronounced long term improvements.

Background: Many studies have demonstrated that deferral of percutaneous coronary intervention (PCI) on the basis of a myocardial fractional flow reserve (FFR) ≥0.75 is associated with a very low coronary event rate. However, some groups have empirically chosen the cut-off value of 0.80 rather than 0.75 for decision to defer PCI and the FFR measurement between 0.75 and 0.80 has been established as a grey zone. The aim of this study was to evaluate the long-term clinical outcomes of patients with moderate coronary lesions and FFR measurements between 0.75 and 0.80. Methods: The study included 125 anigiographically moderate coronary lesions (>50% diameter stenosis by visual assessment) in 125 patients but in whom the PCI was deferred on the basis of an FFR ≥ 0.75. The FFR was calculated as the ratio of mean distal pressure divided by the proximal pressure during hyperemia. Patients were divided into two groups according to the result of FFR: ≥ 0.80 (n=99, group 1) and between 0.75 and 0.79 (n=26, group 2). We evaluated the long-term major adverse cardiovascular events (MACE) related and unrelated to the FFR-evaluated lesion. Results: During a follow-up period of 82 ± 29 months (mean ± SD), The Kaplan-Meier event-free survival curves showed that group 2 was poorer than group 1 in prognosis (p=0.0148). The incidence of MACE unrelated FFR-evaluated lesion in group 1 was equivalent to that in group 2 (p=0.96). Conclusions: In patients with moderate coronary lesions and borderline FFR measurements, deferral of PCI was associated with a higher rate of MACE related to the FFR-evaluated lesion. FFR cut-off point of 0.80 instead of 0.75 may be more appropriate for deferring PCI.

Mitral regurgitation due to bileaflet prolapse and ischemic causes can be difficult to repair. Midterm experience of the Alfieri edge-to-edge repair as an alternative to valve replacement is reported. Twenty-six patients with severe mitral regurgitation underwent the Alfieri repair between January 1998 and December 2000 (group 1); 15 cases were due to bileaflet prolapse and 7 were of ischemic origin. During the same period, valve replacement was performed in 36 patients (group 2), 20 of whom had similar indications. Follow-up was complete to a mean of 15 months (range, 1–28 months). There was no early death in either group. During follow-up, there was no reoperation in group 1, while 2 patients in group 2 required reoperations due to prosthetic valve endocarditis. There were 4 major thromboembolic or bleeding events in group 2, and none in group 1. All patients in group 1 had trivial to mild mitral regurgitation on follow-up echocardiography. The mean mitral valve gradient was significantly higher in group 2 compared to group 1 (7.2 versus 3.2 mm Hg, p = 0.001). The edge-to-edge repair is associated with good early and midterm results. Long-term follow-up is required to evaluate the durability of this technique.

Background: Septic arthritis (SA) of the knee after anterior cruciate ligament reconstruction (ACLR) is a rare but potentially devastating condition. In certain cases, graft removal becomes necessary. Purpose: To evaluate clinical, subjective, and radiologic outcomes of patients with SA after ACLR and assess whether graft retention has superior clinical results as compared with graft removal. Study Design: Cohort study; Level of evidence, 3. Methods: All patients who were at least 12 months out from arthroscopic treatment of SA after isolated ACLR at our institution were eligible for inclusion. Patients were categorized into 2 groups: group 1, patients with initial graft retention; group 2, patients with initial graft removal. Group 2 was subdivided into 2 groups: group 2a, patients with graft reimplantation; group 2b, patients without graft reimplantation. Objective and subjective assessments were obtained at follow-up, including the International Knee Documentation Committee (IKDC) knee examination form, KT-1000 arthrometer measurements, WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) score, Lysholm score, and IKDC subjective evaluation. Radiologic assessment was performed with pre- and postoperative magnetic resonance imaging. Results: Of the 41 patients included, 33 (81%) were available for follow-up at a mean ± SD 54.7 ± 24.4 months at an age of 28.4 ± 9.3 years. When compared with patients from group 2 (n = 12), patients from group 1 (n = 21) obtained significantly better results on the objective IKDC score (normal or nearly normal: group 1, 66.6%; group 2, 36.4%; P = .047) and KT-1000 measurements (group 1, 1.3 ± 1.0 mm; group 2, 2.9 ± 1.5 mm; P = .005). Group 1 also scored better than group 2 on the Lysholm ( P = .007), IKDC subjective ( P = .011), and WOMAC ( P = .069) measures. Between groups 2a (n = 4) and 2b (n = 8), no significant differences in outcomes could be detected ( P values, .307-.705), although patients with anterior cruciate ligament graft reimplantation showed a clear tendency toward better results in objective and not subjective parameters. Magnetic resonance imaging evaluation showed higher rates of cartilage damage and meniscal tears among patients with graft resection versus graft retention. Conclusion: Patients with graft retention showed superior postoperative results when compared with patients who underwent initial graft resection, although subanalysis showed comparable outcomes between graft retention and reimplantation. Thus, while graft-retaining protocols should have the highest priority in the treatment of SA after ACLR, graft reimplantation should be performed in cases where graft resection becomes necessary, to avoid future cartilage and meniscal lesions. Finally, further studies with larger numbers of patients are needed to gain a better understanding of the outcomes of patients with SA after ACLR.

236 Background: To assess outcomes after artificial urinary sphincter implantation in men who received prior pelvic radiation therapy. Methods: Between 1997 and 2012, 107 patients were identified from the Scott and White Hospital database who underwent artificial urinary sphincter implantation for urinary incontinence after prostate cancer treatment. Of these 17 were excluded for lack of follow-up data. Of the remaining 90 patients, 59 patients underwent prior surgery alone (group 1), 25 underwent prior surgery followed by pelvic radiation therapy (group 2); and 6 patients underwent prior radiation therapy alone. Results: Average ages at sphincter implantation were 69 yrs. (range 54 - 82), 73 yrs. (range 63 - 81), and 70 yrs. (range 60 - 80) respectively for groups 1, 2 and 3. Social continence rates were 80% (47/59) for group 1, 72% (18/25) for Group 2 and 50% (3/6) for group 3 at an average follow-up of 6 yrs. (range 0 - 17), 4 yrs. (range 1 - 12) and 3 yrs. (range 0 - 6) respectively. Average time between surgery and sphincter implantation was 5 yrs. (range 1-27) in group 1. Average time between radiation and sphincter implantation was 7 yrs. (range 1 - 18) and 6 yrs. (range 1 - 17) in Groups 2 and 3. Re-operation rates were 42% (25/59); 48% (12/25); and 50% (3/6) in groups 1, 2, and 3, respectively. In men who were incontinent at last follow-up, the average time between pelvic radiation and sphincter placement was relatively shorter as compared to those who were continent [5 yrs. (range 1 -11) vs. 7 yrs. (range 1 - 18) in Group 2; and 4 yrs. (range 1 -5) vs.10 yrs. (range 4 - 17) in group 3]. The rates of erosions were 10/59 (17%); 4/25 (16%); and 0/6 (0%) in groups 1, 2, and 3, respectively. The rates of infection were 5/59 (8%), 0/25 (0%), and 2/6 (33%) in groups 1, 2, and 3, respectively. Conclusions: Our experience with artificial urinary sphincter in men who underwent prior pelvic radiation therapy is comparable to that reported in the literature. Our results identify factors associated with worse continence after artificial urinary sphincter in men who underwent prior pelvic radiation therapy.
