Unifocalization cannot rely exclusively on native pulmonary arteries: the importance of recruitment of major aortopulmonary collaterals in 249 cases†

Abstract OBJECTIVES: We sought to define the early and late outcomes of unifocalization based on a classification of the native pulmonary artery (nPA) system and major aortopulmonary collateral arteries (MAPCAs) with a policy of combined recruitment and rehabilitation and to analyse the role of unifocalization by leaving the ventricular septal defect (VSD) open with a limiting right ventricle-pulmonary artery (RV-PA) conduit in borderline cases. METHODS: An analysis of 271 consecutive patients assessed for unifocalization at a single institution between 1988 and 2016 was performed. Patients were classified according to the pulmonary blood supply: group A, unifocalization based on nPA only; group B, based on nPA and MAPCAs; group C, MAPCAs only (absent nPAs). RESULTS: Unifocalization was achieved in 249 (91.9%) cases with an early mortality of 2.8%. Group A included 72 (28.9%) patients, group B 119 (47.8%) patients and group C 58 (23.3%) patients with no difference in early survival between groups. Survival at 5, 10 and 15 years was 90.0% (85.9–94.3), 87.2% (83.5–91.2) and 82.3% (75.2–89.9), respectively. Late survival in groups A and B was similar but 10- and 15-year survival in group C decreased to 79.2% (68.2–92.1) and 74.3% (61.1–90.4) (P = 0.02), respectively. A mean of 1.9 (±0.6) MAPCAs were recruited per patient (range 0–6). The VSD was left open with a limiting RV-PA conduit in 97 (39.0%) cases, but subsequently closed in 48 patients, giving a total of 200 (80.3%) patients achieving VSD closure (full repair). Delaying VSD closure was not associated with increased risk for early or late survival. A central shunt to rehabilitate the nPAs was used in 56 (22.5%) cases. This was associated with a reduction in the number of MAPCAs recruited, but still required a mean of 1.8 (±0.5) MAPCAs recruited per patient to achieve unifocalization. In multivariate risk analysis, those suitable for single-stage full repair had the best long-term outcomes. Group C anatomy was associated with poor late survival compared to groups A and B (hazard ratio 2.7). CONCLUSIONS: Survival is maximized by a combined approach of rehabilitation and recruitment. MAPCAs should always be recruited if they supply areas with absent nPA supply. A strategy of leaving the VSD open with a limiting RV-PA conduit is a safe and effective way of managing borderline cases.

Background Current guidelines recommend referral of patient with renal failure for access creation 6 months before planned dialysis. There is a growing cohort of patients that require long-term hemodialysis without adequate preparation. Temporary dialysis catheters and rapid access arteriovenous grafts (AVG) are far from being an ideal solution in this scenario. In an effort to expedite maturation of autogenous arteriovenous fistulae (AVF), balloon-assisted maturation (BAM) was advised by some authors. This technique still lacks the support of high-level evidence studies. We investigated the ability of intra-operative BAM to induce early functional maturation of AVFs. Methods This is a prospective randomized controlled study conducted in a tertiary referral center, with a catchment area of more than 15 million population. Cases were divided into two groups; Group (A), where BAM technique was performed, while in the control group (B), the standard technique was used (NO BAM) for creation of AVFs. Results Between June 2017 and May 2019, 300 cases were recruited from a total of 648 primary AVF creation instances. Patients’ age ranged from 19 to 89 (mean 51.17 ±SD 15.5) years. Group A (BAM) included 52.3% ( n = 157) AVFs, while Group B included 47.7% ( n = 143) AVFs. The average maturation time was 3.7 weeks (SD ± 1.3, 95% CI 3.55–3.95) and 5.91 weeks (SD ± 2.2, 95% CI 5.55–6.26) for both groups, respectively ( p = 0.0001). 78.3% of the AVFs that underwent BAM showed early maturation within 2–4 weeks vs 32.2% only in the NO BAM group ( p = 0.002). Successful functional maturation was higher among cases of the BAM group (93%), compared to the NO BAM group (77%) ( p = 0.001). Complication rates were 9.6% and 4.9% in the two groups, respectively ( p = 0.042). Conclusion BAM can play a pivotal role in helping the dialysis society meet the goals of the Fistula First Initiative, keeping in mind that this comes with an increased risk of complications. BAM should be considered only when unplanned early access to long-term dialysis is required.

Background: Frozen shoulder is disorder of the connective tissue that limits the normal Range of motion of the shoulder in diabetes, frozen shoulder is thought to be caused by changes to the collagen in the shoulder joint as a result of long term Hypoglycemia. Mobilization is a therapeutic movement of the joint. The goal is to restore normal joint motion and rhythm. The use of mobilization with movement for peripheral joints was developed by mulligan. This technique combines a sustained application of manual technique “gliding” force to the joint with concurrent physiologic motion of joint, either actively or passively. This study aims to find out the effects of mobilization with movement and end range mobilization in frozen shoulder in Type I diabetics. Materials and Methods: 30 subjects both male and female, suffering with shoulder pain and clinically diagnosed with frozen shoulder was recruited for the study and divided into two groups with 15 patients each based on convenient sampling method. Group A patients received mobilization with movement and Group B patients received end range mobilization for three weeks. The outcome measurements were SPADI, Functional hand to back scale, abduction range of motion using goniometer and VAS. Results: The mean values of all parameters showed significant differences in group A as compared to group B in terms of decreased pain, increased abduction range and other outcome measures. Conclusion: Based on the results it has been concluded that treating the type 1 diabetic patient with frozen shoulder, mobilization with movement exercise shows better results than end range mobilization in reducing pain and increase functional activities and mobility in frozen shoulder.

Background: Laparoscopic Incisional and Ventral Hernia Repair (LIVHR) is a safe and worldwide accepted procedure performed using absorbable tacks. The aim of the study was to evaluate recurrence rate in a long term follow-up and whether the results of laparoscopic IVH repair in the elderly (≥65 years old) are different with respect to results obtained in younger patients. Methods: One hundred and twenty-nine consecutive patients (74 women and 55 men, median age 67 years, range = 30-87 years) with ventral (N = 42, 32.5%) or post incisional (N = 87, 67.5%) hernia were enrolled in the study. Patients were divided into two groups according to their age: group A (N = 55, 42.6%) aged <65 years and group B (N = 74, 57.4%) aged ≥65 years. Results: The mean operative time was not significantly different between groups (66.7 ± 37 vs. 74 ± 48.4 min, p = 0.4). To the end of 2016, seven recurrences had occurred (group A = 3, group B = 4, p = 1). Complications occurred in 8 (16%) patients in group A and 21 (28.3%) patients in group B. Conclusion: In conclusion, our results confirm that the use of absorbable tacks does not increase recurrence frequency and laparoscopic incisional and ventral repair is a safety procedure also in elderly patients.

Treatment of congenital pseudarthrosis of the tibia remains a major challenge in pediatric orthopedics. Ideal timing and preference of surgical procedures are discussed controversially. A variety of reconstructive treatment strategies have been described in literature, but so far none has proven its superiority. The aim of treatment is to obtain long-term bone union, to prevent refracture, and to correct angular deformities and leg length discrepancies. This study retrospectively evaluates the outcome of different reconstructive strategies. Sixty-nine patients were identified who presented to our outpatient department between 1997 and 2019. Twenty-six of these patients underwent reconstructive surgical treatment and were included in this study. The study cohort was divided into three groups. Excision of the pseudarthrosis was performed in all patients in Group A and B, and in two patients of Group C. Group A (six/26 patients) received subsequent bone transport through external fixation maintaining original length. In Group B (15/26 patients), patients underwent either previous, simultaneous, or subsequent extrafocal lengthening through external fixation to reconstitute length. In Group C (five/26 patients), internal fixation with intramedullary nails was applied. Radiological and clinical evaluation was performed to assess bone union and complication rates. Results varied considerably between the study groups. Overall, the primary bone fusion rate was 69.2%. There were four refractures, all occurring in Group B. The long-term bone union rate without refracture was 53.8%. The overall complication rate was 53.8% and 23.1% showed persistent pseudarthrosis. Two secondary amputations were performed due to failed bone fusion. In conclusion, excision of the pseudarthrosis and extrafocal lengthening achieves a satisfying bone union rate and limb reconstruction, while bone transport does not offer significant advantages but shows higher complication rates. Intramedullary stabilization should be applied to maintain bone union, but shows lower bone union rates when used as a stand-alone treatment regimen. Regardless of the primary bone fusion rates, the probability of long-term bone union remains unpredictable.

Abstract Introduction Management of complicated diverticulitis has shifted towards a conservative approach over time. This study evaluates the feasibility and long-term outcomes of conservative management. Method We retrospectively evaluated a consecutive series of patients managed with perforated colonic diverticulitis from 2013-2017. Results Seventy-three (73) patients were included with a male to female ratio of 1:2. Thirty-one (31) underwent Hartmann’s procedure (Group A) and 42 patients were managed with antibiotics +/- radiological drainage (Group B). Mean follow-up was 64.9 months (range 3-7 years). CT Grade 3 and 4 disease was observed in 64.5% and 40.4% of Group A and Group B patients, respectively. During follow-up, 9 (21.4%) Group B patients required Hartmann’s. Group A had longer median length of stay compared to Group B (25.1 vs 9.2 days). Post-operative complications occurred in 80.6% with 40% being Clavien-Dindo grade III or higher in group A. Stoma reversal was performed in 8 patients (25.8%). Conclusions In carefully selected cases, complicated diverticulitis including CT grade 3 and 4 disease, can be managed conservatively with acceptable recurrence rates (16.7% at 30 days, 4.8% at 90 days, 19.0% at 5 years). Surgical intervention on the other hand, carries high post-operative complication rates and low stoma reversal rates.

Objective: The aim of this study was to assess the long-term effectiveness of quantic molecular resonance (QMR) in the treatment of inferior turbinate hypertrophy (ITH) in allergic and nonallergic rhinitis refractory to medical therapy. Methods: This study enrolled 281 patients, 160 males (56.9%) and 121 females (43.1%), mean age 37.8 ± 4.1 years, range 18 to 71. Fifty-four patients have been lost to follow up and have been therefore excluded from the final analysis. Based on skin prick test results, 69 patients were considered allergic (group A) and 158 nonallergic (group B). All subjects underwent before surgery (T0) and 3 (T1), 12 (T2), 24 (T3), and 36 months (T4) after QMR treatment to: 4-phase rhinomanometric examination, nasal endoscopy evaluation, and visual analogue scale to quantify the subjective feelings about nasal obstruction. Results: Subjective and objective parameters showed statistically significant improvement in both groups. Group B parameters not changed during follow-up, while group A showed significant worsening between T1 and subsequent assessments. T4 outcome indicates a better result in nonallergic patients. Conclusions: In accordance with the literature, our preliminary data validate QMR treatment as a successful therapeutic option for nasal obstruction due to ITH. Nonallergic patients had a very good T4 outcome. Allergic patients showed a worsening trend after 1 year probably due to other causes.

OBJECTIVE Posterior C1–2 fixation without fusion makes it possible to restore atlantoaxial motion after removing the implant, and it has been used as an alternative technique for odontoid fractures; however, the long-term efficacy of this technique remains uncertain. The purpose of the present study was to explore the long-term follow-up outcomes of patients with odontoid fractures who underwent posterior C1–2 fixation without fusion. METHODS A retrospective study was performed on 62 patients with type II/III fresh odontoid fractures who underwent posterior C1–2 fixation without fusion and were followed up for more than 5 years. The patients were divided into group A (23 patients with implant removal) and group B (39 patients without implant removal) based on whether they underwent a second surgery to remove the implant. The clinical outcomes were recorded and compared between the two groups. In group A, the range of motion (ROM) of C1–2 was calculated, and correlation analysis was performed to explore the factors that influence the ROM of C1–2. RESULTS A solid fracture fusion was found in all patients. At the final follow-up, no significant difference was found in visual analog scale score or American Spinal Injury Association Impairment Scale score between the two groups (p > 0.05), but patients in group A had a lower Neck Disability Index score and milder neck stiffness than did patients in group B (p < 0.05). In group A, 87.0% (20/23) of the patients had atlantoodontoid joint osteoarthritis at the final follow-up. In group A, the C1–2 ROM in rotation was 6.1° ± 4.5° at the final follow-up, whereas the C1–2 ROM in flexion-extension was 1.8° ± 1.2°. A negative correlation was found between the C1–2 ROM in rotation and the severity of tissue injury in the atlantoaxial region (r = –0.403, p = 0.024) and the degeneration of the atlantoodontoid joint (r = –0.586, p = 0.001). CONCLUSIONS Posterior C1–2 fixation without fusion can be used effectively for the management of fresh odontoid fractures. The removal of the implant can further improve the clinical efficacy, but satisfactory atlantoaxial motion cannot be maintained for a long time after implant removal. A surgeon should reconsider the contribution of posterior C1–2 fixation without fusion and secondary implant removal in preserving atlantoaxial mobility for patients with fresh odontoid fractures.

Background: Percutaneous, transverse distal metatarsal osteotomy with K-wire fixation (the Bösch technique) is an established technique for hallux valgus correction. Nevertheless, the risk of damaging the anatomical structures during the operation is unknown. Methods: Forty fresh-frozen anatomical foot specimens with hallux valgus deformity underwent a percutaneous corrective procedure. Specimens of group A (n = 20) were operated by an experienced surgeon while specimens of group B (n = 20) were done by untrained residents. Results: The dorsal cutaneous nerve was injured in 1 of 20 cases in group A and 6 of 20 cases in group B ( P = .037). There was a significant difference in overall complication rate between specimens of group A and group B ( P = .043). Conclusions: The results show an increased risk of perioperative injury of the dorsal cutaneous branch of the deep peroneal nerve as well as a significant effect of the surgeon’s experience on the overall complication rate. Clinical Relevance: Results of this study are highly relevant for all surgeons who perform percutaneous, minimally invasive hallux valgus surgery to avoid damage to the peripheral nerves. In addition, the data suggest an intensive training for surgeons before minimally invasive hallux valgus surgery is performed without supervision.

Introduction: The randomized controlled VOLCANO trial demonstrated comparable 1-year rhythm outcomes between patients with and without ablation targeting low-voltage areas (LVAs) in addition to pulmonary vein isolation among paroxysmal atrial fibrillation (AF) patients with LVAs. To compare long-term AF/atrial tachycardia (AT) recurrence rates and types of recurrent-atrial-tachyarrhythmia between treatment cohorts during a > 2-year follow-up period. Methods: An extended-follow-up study of 402 patients enrolled in the VOLCANO trial with paroxysmal AF, divided into 4 groups based on the results of voltage mapping: Group A, no LVA (n=336); group B, LVA ablation (n=30); group C, LVA presence without ablation (n=32); and group D, incomplete voltage map (n=4). Results: At 25 (23, 31) months after the initial ablation, AF/AT recurrence rates were 19% in group A, 57% in group B, 59% in group C, and 100% in group D. Recurrence rates were higher in patients with LVAs than those without (group A vs. B+C, p<0.0001), and were comparable between those with and without LVA ablation (group B vs. C, p=0.83). Among patients who underwent repeat ablation, ATs were more frequently observed in patients with LVAs (Group B+C, 50% vs. A, 14%, p<0.0001). In addition, LVA ablation increased the incidence of AT development (group B, 71% vs. C, 32%, p<0.0001), especially biatrial tachycardia (20% vs. 0%, p=0.01). Conclusion: Patients with LVAs demonstrated poor long-term rhythm outcomes irrespective of LVA ablation. ATs were frequently observed in patients with LVAs, and LVA ablation might exacerbate iatrogenic ATs.

Donor Liver Transplant

Background: This study aimed to determine the association between episodic or persistent hematuria after liver transplantation and long-term renal outcomes. Methods: Patients who underwent living donor liver transplantation between July 2005 and June 2019 were recruited and divided into two groups based on the finding of microscopic or gross hematuria after transplantation. All patients were followed up from the index date until the end date in May 2020. The risks of chronic kidney disease, death, and 30% and 50% declines in estimated glomerular filtration rate (eGFR) were compared between groups. Results: A total of 295 patients underwent urinalysis for various reasons after undergoing transplantation. Hematuria was detected in 100 patients (group A) but was not present in 195 patients (group B). Compared with group B, group A had a higher risk of renal progression, including eGFR decline >50% [aHR = 3.447 (95%CI: 2.24~5.30), p < 0.001] and worse survival. In addition, patients who took non-steroidal anti-inflammatory drugs (NSAIDs) continuously for over seven days within six months before transplant surgery had high risks of rapid renal progression, including a >30% decline in eGFR [aHR = 1.572 (95%CI: 1.12~2.21), p = 0.009)]. Conclusion: Development of hematuria after surgery in patients who underwent living donor liver transplant and were exposed to NSAIDs before surgery were associated with worse long-term renal dysfunction and survival.
