Object The goal of this report was to describe the authors' initial experiences with an adjustable gravity-assisted valve (GAV) called the ProGAV in treating childhood hydrocephalus. Methods The ProGAV was implanted in 53 children (29 boys and 24 girls, median age 7.3 years) with hydrocephalus of various origins. The ProGAV consists of a differential-pressure unit with adjustable opening pressures and a gravitational unit with a fixed opening pressure. Results The mean follow-up period was 15.2 months (range 6–44 months). The authors did not observe any valve-related complications. Four infections (7.5%) occurred, warranting the removal of the shunt. In 19 children, the opening pressure was changed at least once during the follow-up period, for underdrainage in 10, overdrainage in 8, and shunt weaning in 1, with substantial clinical improvement in 18 children. Overall, good clinical results were obtained in 47 (88.7%) of the 53 valve placements. Conclusions With an overall success rate of 88.7%, the first experiences with the ProGAV in childhood hydrocephalus are promising and justify its further use in the pediatric population.

OBJECTIVE In this study, the authors aimed to describe a new technique of sacroiliac joint (SIJ) fusion using a robotic navigation guidance system and to document clinical results with patient-reported visual analog scale (VAS) scores. METHODS Patients diagnosed with SIJ dysfunction were surgically treated using 2 hydroxyapatite (HA)–coated, threaded screws with the aid of the robotic navigation system. In a total of 36 patients, 51 SIJs were fused during the study period. Patients’ VAS scores were used to determine clinical improvement in pain. Postoperative imaging at routine intervals during the follow-up period was also performed for assessment of radiological fusion. In addition, complication events were recorded, including reoperations. RESULTS All 36 patients had successful fusion evidenced by both CT and clinical assessment at the final follow-up. Two patients underwent reoperation because of screw loosening. The mean preoperative VAS score was 7.2 ± 1.1, and the mean 12-month postoperative VAS score was 1.6 ± 1.46. This difference was statistically significant (p < 0.05) and demonstrated a substantial clinical improvement in pain. CONCLUSIONS Robotic navigation–assisted SIJ fusion using 2 HA-coated, threaded screws placed across the joint was an acceptable technique that demonstrated reliable clinical results with a significant improvement in patient-reported VAS pain scores.

Background: We investigated the long-term clinical results of percutaneous transluminal angioplasty (PTA) in patients with peripheral arterial occlusive disease (PAOD) and the influence of different parameters on the primary success rate, the rate of complications and the long-term outcome. Patients and methods: We reviewed clinical and hemodynamic follow-up data of 166 consecutive patients treated with PTA in 1987 in our department. Results: PTA improved the clinical situation in 79.4% of patients with iliac lesions and in 88.3% of patients with femoro-popliteal lesions. The clinical stage and ankle brachial index (ABI) post-interventional could be improved significantly (each P < 0,001), the same results were observed at the end of follow-up (each P < 0,001). Major complications occurred in 11 patients (6.6%). The rate of primary clinical long-term success for suprainguinal lesions was 55% and 38% after 5 and 10 years (femoro-popliteal 44% and 33%), respectively, the corresponding data for secondary clinical long-term success were 63% and 56% (60% and 55%). Older age (P = 0,017) and lower ABI pre-interventional (P = 0,019) significantly deteriorated primary clinical long-term success for suprainguinal lesions, while no factor could be identified influencing the outcome of femoro-popliteal lesions significantly. Conclusion: Besides an acceptable success rate with a low rate of severe complications, our results demonstrate favourable long-term clinical results of PTA in patients with PAOD.

Object In the modern era, stereotactic radiosurgery is an important part of the multidisciplinary and multimodality approach used to treat dural carotid-cavernous fistulas (DCCFs). Based on the ease of performance of techniques to fuse cerebral angiography studies with MR images or CT scans during the radiosurgical procedure, the Gamma Knife and XKnife are 2 of the most popular radiosurgical instruments for patients with DCCF. In this study, the authors compared the efficacy, neurological results, and complications associated with these 2 radiosurgical devices when used for DCCF. Methods Records for 41 patients with DCCF (15 treated using the XKnife and 26 with Gamma Knife surgery [GKS]) were retrieved from a radiosurgical database encompassing the period of September 2000 to August 2008. Among these patients, at least 2 consecutive MR imaging or MR angiography studies obtained after radiosurgery were available for determining radiological outcome of the fistula. All patients received regular follow-up to evaluate the neurological and ophthalmological function at an interval of 1–3 months. The symptomatology, obliteration rate, radiation dose, instrument accuracy, and adverse effects were determined for each group and compared between 2 groups. The data were analyzed using the Student t-test. Results The mean age of the patients was 63 ± 2.6 years, and the mean follow-up period was 63.1 ± 4.4 months (mean ± SD). Thirty-seven patients (90%) achieved an obliteration of the DCCF (93% in the XKnife cohort and 88% for the GKS cohort). In 34 of 40 patients (85%) with chemosis and proptosis of the eyes, these symptoms were resolved after treatment (4 had residual fistula and 2 had arterializations of sclera). All 5 patients with high intraocular pressure demonstrated clinical improvement. Ten (71%) of 14 patients with cranial nerve palsy demonstrated improvement following radiosurgery. Significant discrepancies of treatment modalities existed between the XKnife and GKS groups, such as radiation volume, conformity index, number of isocenters, instrument accuracy, peripheral isodose line, and maximum dosage. The XKnife delivered significantly higher radiation dosage to the lens, optic nerve, optic chiasm, bilateral temporal lobe, and brainstem. Few adverse events occurred, but included 1 patient with optic neuritis (GKS group), 1 intracranial hemorrhage (XKnife group), 1 brainstem edema (XKnife), and 3 temporal lobe radiation edemas (XKnife). Conclusions Radiosurgery affords a substantial chance of radiological and clinical improvement in patients with DCCFs. The Gamma Knife and XKnife demonstrated similar efficacy in the obliteration of DCCFs. However, a slightly higher incidence of complications occurred in the XKnife group.

Purpose: To describe our experience with a modified frontal muscle advancement flap to treat patients with severe congenital ptosis. Methods: Analysis of the clinical charts of 154 patients who underwent a modified frontal muscle advancement flap. The FM was exposed by a crease incision. The FM flap was created by deep dissection between the orbicularis muscle and orbital septum from the skin crease incision to the supraorbital margin and subcutaneous dissection from the inferior margin of the eyebrow to 0.5 cm above the eyebrow. No vertical incision was made on the FM flap to ensure an intact flap wide enough to cover the entire upper tarsal plate. Contour, symmetry of height, marginal reflex distance (MRD1), and complications were assessed. Mean follow-up was 10 months. Results: The mean patient age was 7.6 ± 5.6 (range, 2–18) years. The mean MRD1 was 3.2 ± 1.3 mm after the operation. All bilateral cases achieved symmetry and optimal lid contour; 17 unilateral cases were under corrected, with a success rate of 89.0%. Complications such as entropion, exposure keratitis, FM paralysis, frontal hypoesthesia, severe haematoma, and entropion were not observed in our series. Conclusion: A modified frontal muscle advancement flap produced a high success rate with a clear field of vision, mild trauma, and few complications. This technique is relatively simple and should be considered for correcting severe congenital ptosis.

Abstract Background Modified tension band fixation has become commonly used for transverse patella fractures. The conventional stainless steel wire provides sufficient stability but may be associated with complications. Objective The study aimed to evaluate the effectiveness of a new modified tension band fixation technique for transverse patella fractures using a nonabsorbable suture. Material and methods We present the result of a prospective series using a nonabsorbable suture (FiberWire) for transverse patella fractures. The mean follow-up period totaled 12 months. A total of 16 patients were evaluated by radiographic and clinical review. The postoperative clinical evaluation employed Lysholm and Böstman scores. Result All clinical results on follow-up were good to excellent. Minimal intra-articular joint stepping and further fracture displacement were recorded. No patient needed re-operation, and functional outcomes of the knee were satisfactory. No significant differences were found between the injured and contralateral knee range of motion. No symptomatic implants and skin complications were noted, and all fractures were completed heal within 15 weeks. Conclusion FiberWire provided sufficient stability and reduced postoperative complications. The results proved appropriate, and the technique has merit, as it obviates the need for re-operation.

Abstract Background Different surgical methods have been suggested for the correction of intermittent exotropia. Unilateral lateral rectus recession has been described as a surgical alternative for small and moderate-angle exotropia. In general, previous studies did not focus on the outcomes of unilateral lateral rectus recession in young children with intermittent exotropia. The purpose of this study is to evaluate the surgical outcomes of unilateral lateral rectus recession in the treatment of moderate-angle exotropia (≤ 25 PD (prism diopters)) in children. Methods The charts of all patients younger than 12 years of age with moderate-angle exotropia (up to 25 PD) who were operated during the years 2006–2018 were retrospectively reviewed. Fifty-eight patients underwent unilateral lateral rectus recession and had a minimum follow up of 6 months. The angle of exotropia (PD) before and after surgery and the success rate were documented. Results Mean age at surgery was 6.4 ± 1.9 (range 3.5–11.0) years. Exotropia improved from a preoperative angle of 21.4 ± 4.0 PD to 3.5 ± 5.9 PD postoperatively (p < 0.001). Success rate, defined as deviation of ≤ 10 PD, was achieved in 86.2%. There were 2 (3.4%) cases of overcorrection (consecutive esotropia). There were no intra- or postoperative complications. The mean follow-up duration after surgery was 2.3 ± 1.7 years. Conclusions In children with moderate angle exotropia, good postoperative success rate was achieved by performing unilateral lateral rectus recession.

Abstract Funding Acknowledgements Type of funding sources: None. INTRODUCTION CRH in patients with ischemic heart disease is recommended by the different clinical practice guidelines with an IA level of evidence, with an important role in reducing cardiovascular mortality and hospital readmissions during follow-up. OBJECTIVE The goal of this study is to show the 4-year clinical results of a population of patients who participated in an CRH program after an Acute Coronary Syndrome (ACS). METHODS Between May/2014 and September/2017, 221 patients who had recently presented an ACS completed the 12 weeks of phase II of the CRH program at our center. In May/2020 we collected epidemiological, clinical and echocardiographic information at the time of the acute cardiovascular event; and we evaluate the current vital status of the patients and the incidence of readmissions for: angina, HF, new ACS, or arrhythmic events. RESULTS Of the 221 patients, 182 were men (82%). The mean age of our population was 58.3 ± 7.8 years. 58% (129 patients) suffered from ST-elevation ACS. The mean time of hospital stay was 6.20 ± 2.9 days. An echocardiogram was performed at discharge, which showed an average LVEF of 56 ± 6%. Eight patients (4%) developed early Ventricular Fibrilation (VF) during the acute phase of ACS. Among the classic CVRF, smoking (79%) was the most prevalent, followed by dyslipidemia (53%) and hypertension (47%). The mean time from hospital discharge to the start of phase II RHC was 42 ± 16 days. The overall incidence of events was 9%: 10 patients suffered reinfarction during follow-up, and 7 were readmitted for unstable angina, all of whom underwent PCI; no patient was admitted for HF; and none of the 8 patients with early VF had a new tachyarrhythmia, registering a single admission for VT during follow-up. None of the patients had sustained ventricular tachyarrhythmias during exercise-training. At the mean 4.5-year follow-up, 218 patients were still alive (98%). CONCLUSION The incidence of CV events in the follow-up of our cohort was low, which can be explained by the fact that it is a young population, with an LVEF at low limits of normality at discharge, which is one of the most important predictors in the prognosis after an ischemic event. As an improvement, we must shorten the time until the start of phase II of the program. CRH shows once again its clinical benefit after an ACS, in consonance with the existing evidence.

Background Several studies have shown comparable early efficacy of mechanochemical ablation to endothermal techniques. The goal of this report was to show if early efficacy is maintained at 24 months. Methods This was a two-year analysis on the efficacy of mechanochemical ablation in patients with symptomatic C2 or more advanced chronic venous disease. Patients with reflux in the great saphenous vein involving the sapheno-femoral junction and no previous venous interventions were included. Demographic information, clinical, and procedural data were collected. The occlusion rate of treated veins was assessed with duplex ultrasound. Patient clinical improvement was assessed by Clinical-Etiology-Anatomy-Pathophysiology (CEAP) class and venous clinical severity score. Results Of the initial 126 patients, there were 65 patients with 24 month follow-up. Of these 65 patients, 70% were female, with a mean age of 70 ± 14 years and an average body mass index (BMI) of BMI of 30.5 ± 6. The mean great saphenous vein diameter in the upper thigh was 7.6 mm and the mean treatment length was 39 cm. Adjunctive treatment of the varicosities was performed in 14% of patients during the procedure. Closure rates were 100% at one week, 98% at three months, 95% at 12 months, and 92% at 24 months. There was one patient with complete and four with partial recanalization ranging from 7 to 12 cm (mean length 9 cm). There was significant improvement in CEAP and venous clinical severity score (P < .001) for all time intervals. Conclusion Early high occlusion rate with mechanochemical ablation is associated with significant clinical improvement which is maintained at 24 months, making it a very good option for the treatment of great saphenous vein incompetence.

Background: Severely incurved toenails are accompanied by deformity of the toenail growth plate. In such a condition, partial removal of the nail and nail bed and simple unfolding of the nail itself frequently result in the recurrence of symptoms. We sought to design and develop a new technique for the treatment of incurved toenail with growth plate deformity and to report the results of treating this disease entity. Methods: Forty consecutive patients (52 cases) underwent treatment of symptomatic incurved toenails with a new technique named matrixplasty. The mean ± SD patient age was 40.3 ± 18.9 years. Last follow-up was at a mean ± SD of 18.0 ± 1.3 months. An American Orthopedic Foot and Ankle Society (AOFAS) forefoot hallux score was assigned, and patients were evaluated before treatment and at last follow-up. Patient satisfaction and the recurrence rate of the deformity were evaluated. For evaluation of improvement in toenail shape, the center to edge angle of the toenail was measured before treatment and at last follow-up. The complication rate was also evaluated. Results: All of the ingrown toenails healed, and the nail deformities were corrected within 3 weeks after the procedure. None of the incurved toenails had recurred by last follow-up. The mean pretreatment AOFAS forefoot hallux score was 72.9, and it improved to 99.6 by last follow-up (P &lt; .001). Every patient was very satisfied or satisfied with the results of treatment. The mean ± SD center to edge angle of the toenail improved from 53.3° ± 9.5° to 15.3° ± 5.2° by last follow-up (P &lt; .001). Minor paronychia, which was managed with local wound dressing and oral antibiotics, was identified in four cases. No other complication was identified. Conclusions: Matrixplasty showed excellent clinical results in the treatment of severe incurved toenail, and this newly developed procedure showed improvement of the deformed toenail and its growth plate.
