Iatrogenic innominate vein injuries are rare complications associated with internal jugular venous catheters. These complications are accompanied by high morbidity and mortality rates in patients with severe underlying medical conditions. Without proper treatment, emergency surgery may be needed due to acute cardiac tamponade or hemothorax. Endovascular repair can be advantageous for patients with significant medical comorbidities. Herein, we report the case of a 62-year-old female with an iatrogenic injury to the innominate vein at the subclavian vein and internal jugular confluence due to a malpositioned left internal jugular catheter. A customized fenestrated endograft was positioned with fenestration oriented to the internal jugular vein and a new tunneled catheter was inserted across the fenestration into the superior vena cava upon removal of the malpositioned catheter. In addition, a brachio-basilic arteriovenous fistula was created. At one month followup, the patient had a palpable thrill over the arteriovenous fistula and a functioning tunneled catheter.

Purpose: Physician-modified endovascular stent grafts (PMEG) are a good treatment option for complex abdominal aortic aneurysms (AAAs), especially in high-risk patients not amenable to open repair, and when commercial fenestrated devices are not available. We report our single-center experience with PMEG for the treatment of complex AAAs. Methods: We retrospectively reviewed patients who underwent PMEG repair for AAA from November 2016 to September 2020 at our institution. Demographic data, anatomic characteristics, perioperative and postoperative outcomes, major adverse events, and 30-day mortality were analyzed. Results: We identified 12 patients who underwent PMEG for complex AAA. The mean age was 74 years and the mean maximal AAA diameter was 58.1 mm. Indications for treatment included 4 impending or contained ruptures, 2 mycotic aneurysms, and 6 symptomatic cases. The technical success rate was 91.7%. Aneurysm sac regression was observed in 7 patients (58.3%), including 2 cases of complete regression. There was 1 aneurysm-related mortality at 3 months due to mycotic aneurysm. Also, there was 1 postoperative complication case of transient renal failure requiring temporary dialysis. At 1 year, there was 1 branch occlusion from the initial failed cannulation case and 2 type 1A endoleaks, and there was 1 case of open explantation. Conclusion PMEG showed a low technical failure rate and acceptable midterm stent durability and sac stability, comparable to conventional endovascular aneurysm repair. Despite the small number of cases, there was a tendency for a high sac regression rate, although longer follow-up is needed.
