ABSTRACT
PURPOSE: Type III endoleak can be difficult to distinguish from Type I endoleak. Depending on the stent graft anatomy, the use of standard bifurcated endografts may not be technically feasible, and patients may have to be subject to an aorto-uni-iliac repair with femoral-femoral bypass or open surgery. CASE REPORT: We report a case of an 86-year-old male who had a Type IIIb endoleak 20 years post EVAR which was characterized on angiography to be from a hole close to the bifurcation limb origin. The initial Talent (Medtronic, Santa Rosa, California) device had a 50 mm main body common trunk, which was not amenable to treatment with standard devices. He was successfully treated with a custom-made device with an inverted contralateral limb. CONCLUSIONS: Our case highlights the need for lifelong surveillance post EVAR as endoleak may present decades post initial EVAR. It also demonstrates that many Type III endoleak which were otherwise deemed unsuitable for treatment with standard devices may potentially be treatable with custom-made device (CMD). This solution preserves a percutaneous option in a now older person which avoids surgical bypass. Further studies are required to establish the durability of this treatment and survey for recurrence.

BACKGROUND: Peritoneal dialysis catheter (PDC)-related infections account for significant morbidity, PD disruptions and costs. Patients with refractory exit-site or tunnel track infections without peritonitis may need catheter removal and reinsertion which can be complicated by bleeding, organ injury, catheter failure or malposition. Some patients may need to switch to haemodialysis in such a setting. An alternative is a salvage procedure. The purpose of this systematic review is to evaluate the safety and efficacy of salvage techniques. METHODS: A comprehensive search of PubMed, Medline and Scopus databases was performed from inception to December 2021 in accordance with PRISMA guidelines. After a broad search, articles were stratified into two main categories for assessment: (1) cuff-shaving (CS) techniques and its variations of en-bloc resection (BR) and/or catheter diversion (CD) and (2) partial reimplantation with CD. RESULTS: A total of 409 patients (445 salvage procedures) from 20 studies were included in analysis. Of 409 patients, 234 patients (57.2%) underwent 251 (56.4%) CS procedures and its variations, 163 patients (39.9%) underwent 182 (40.9%) partial PDC reimplantations with CD and 12 patients (2.7%) underwent local curettage. Overall PDC salvage rate after intervention was 73.2%. Overall PDC removal rate attributable to infection was 26.8%. Overall complication rate attributable to the procedures was 2.7%, with the most common complication being dialysate leakage (n = 10) followed by PDC laceration (n = 1) and subcutaneous haematoma (n = 1). We also included a description of our technique of BR of infected tissue, CS and CD. In a series of six patients, the PDC salvage rate was 83.3% and median PDC survival after intervention was 10 months. CONCLUSION: PDC salvage techniques are relatively safe and provide reasonable catheter salvage rates in selected patients. Results of this review should lend weight to consideration of a salvage-first approach as an option in selected patients.

PURPOSE: While endovascular repair of aortic aneurysm (EVAR) has become the mainstay treatment for abdominal aortic aneurysm (AAA), it is not without its disadvantages. Feared complications include graft infections, fistulation and endoleak, the outcomes of which may be life limiting. CASE REPORT: We present a case of a 57 year-old patient with human immunodeficiency virus (HIV) previously treated with EVAR for AAA complicated by endoleak post treatment. He developed an aorto-psoas abscess 2 years later which harboured Mycobacterium avium complex, and medical therapy was unsuccessful. He eventually underwent an extra-anatomical bypass and graft explant, for which an aortoenteric fistula was also discovered and repaired. CONCLUSION: Infection of endografts post EVAR is relatively rare, and there are presently no guidelines concerning its management. The concomittance of aorto-psoas abscess and aortoenteric fistula is even more uncommon, and necessitated surgical explant for source control purposes in our patient. Lifelong surveillance is required for complications of the aortic stump and bypass patency.

INTRODUCTION: Gallstone(s) impacted at the distal small bowel causing intestinal obstruction as a result of cholecystoenteric fistula is a well-known, albeit uncommon surgical condition. The rare Bouveret's Syndrome, which refers to the proximal impaction of gallstone(s) in the duodenum or pylorus resulting in the gastric outlet obstruction (GOO), has also been described in the literature. However, gallbladder mucocele with extrinsic compression of the duodenum and/or pylorus causing GOO is a separate entity that is extremely rare. PRESENTATION OF CASE: A patient who presented with loss of appetite and weight, with intermittent vomiting over a course of eight months was found to have GOO secondary to extrinsic duodenal compression from a large gallbladder mucocele. Surgical intervention in the form of cholecystectomy was performed, and the patient's symptoms resolved post-operatively. DISCUSSION: We describe an extremely rare case of GOO, which can be easily corrected with cholecystectomy. Removal of the gallbladder removes the root cause of the issue, and should be first line therapy unless the patient is unfit for surgery. CONCLUSION: This extremely rare cause of GOO should be recognized, and treated promptly with surgery if possible.
