Operative and 1-Year Outcomes of the Custom-Made Fenestrated Anaconda Aortic Stent Graft-A UK Multicenter Study.

BACKGROUND: Early and 1-year outcomes are presented for fenestrated endovascular aneurysm repair (FEVAR) of complex aortic aneurysmal disease with the custom-made Anaconda fenestrated stent graft in 101 patients. METHODS: Retrospective site-reported data from the first 101 elective cases (2010-2014) from 4 UK centers were studied to evaluate patient demographics, aneurysm morphology, clinical success, and 1-year outcomes in patients undergoing fenestrated aneurysm repair with the custom-made Anaconda device. RESULTS: 101 fenestrated grafts (median age 76, 85% male) were implanted with a total of 255 fenestrations (196 renal arteries, 48 superior mesenteric artery, and 11 celiac arteries) with 3% mortality, 98.4% target vessel patency (TVP) at 30 day follow-up. Although 15 type I or III endoleaks were demonstrated at completion angiography, all 10 type Ia endoleaks resolved spontaneously. Survival by Kaplan-Meier analysis was 97% and 91% at 1 month and 1 year, respectively; with 75.8% showing reduction in abdominal aortic aneurysm diameter and only 1 patient with sac expansion. Freedom from loss of TVP was 97.6%. CONCLUSIONS: Custom-made fenestrated Anaconda devices demonstrate low procedural mortality and a high rate of technical and clinical success at 30 days and 1 year.

Combined fluoroscopic and ultrasound guided cervical nerve root injections.

PURPOSE: To assess the technical feasibility, safety and initial clinical efficacy of a combined ultrasound and fluoroscopy imaging approach to cervical nerve root blocks. Fluoroscopic guided cervical transforaminal and selective nerve root injections are often used in the investigation or treatment of radicular symptoms, although rare but serious complications including death have been reported. We report a combined technique developed to increase safety of selective nerve root injections, including the safety and early efficacy of this novel technique in our initial patient cohort. METHODS: We retrospectively reviewed a consecutive cohort of injections performed in 149 patients by a single consultant radiologist between December 2010 and August 2012. For all patients the outcome was assessed both immediately following the procedure and at six weeks. Primary outcome was reduction in radicular symptom level. Duration of symptoms were also assessed and all complications were recorded. RESULTS: One hundred and forty nine patients underwent injection at either one or two cervical levels. No patients experienced any complications during the follow-up period, and 72 % had an initial positive response to the injection. Of these, 42 % were discharged to the care of their General Practitioner, 23 % went on to have surgery, 18 % were actively monitored in a specialist clinic, 10 % were referred to our pain management service and 4 % had the injection repeated after symptoms recurred. CONCLUSION: Using this combined image guided technique cervical nerve root blocks appear both safe and effective in the investigation and management of radicular symptoms from the cervical spine.

Large pelvic arteriovenous malformation complicating laparoscopic radical prostatectomy.

Pelvic arteriovenous malformations (AVM) are rare, usually congenital, lesions, which can pose significant difficulties for pelvic surgeons. We present a case of an AVM complicating laparoscopic radical prostatectomy. Unexpected failure of preoperative control led to significant intraoperative difficulty. The advantages of an antegrade approach and optimal magnification afforded by the laparoscopic approach led to successful completion of the operation with minimal morbidity.
