Long-term outcomes of stenting superior cava and brachio-cephalic vein occlusion in hemodialysis patients with arteriovenous fistulas.

Objective: Central vein occlusion (CVO) is a significant complication in patients undergoing chronic hemodialysis, often leading to dialysis inefficacy, disabling symptoms, and, most critically, major risk of access failure. Although stenting has been proposed as a technique to maintain vascular access patency following the recanalization of occluded central veins, the data supporting its long-term efficacy remains limited. This study aims to evaluate the long-term effectiveness of stenting occluded superior vena cava (SVC) and/or brachiocephalic veins to preserve vascular access patency, ensure continued dialysis efficacy, and relieve SVC syndrome.

Aneurysm sac shrinkage after endovascular repair: predictive factors and long-term follow-up.

Background: The aim of this study was to determine the predictive factors of reduction in diameter ≥10 mm of the aneurysm sac after endovascular treatment and analyze evolution in these patients.

Methods: Between December 1997 and December 2008, all patients electively treated at our center for an infrarenal abdominal aortic aneurysm (AAA) were included in a prospective registry. We did a retrospective study between patients whose aneurysm was reduced by at least 10 mm in diameter on computed tomography scan during follow-up (Group 1) and the other patients who did not (Group 2).

Secondary procedures after infrarenal abdominal aortic aneurysms endovascular repair with second-generation endografts.

Background: To study the incidence, the types, and the results of secondary procedures performed after endovascular treatment of infrarenal abdominal aortic aneurysm (AAA). To compare the population of patients who underwent secondary procedure (P2) with the population of those who did not require it.

Material And Methods: Between 1998 and 2008, this study included all the patients electively treated for AAA with stentgrafts that were still available on the market on January 1, 2009.

Challenging catheterization of a branch in an endovascular thoracoabdominal aneurysm repair.

Purpose: To describe a novel technique of cannulating a side branch during endovascular repair of a thoracoabdominal aneurysm (TAAA).

Technique: The approach evolved during endovascular repair of a type III TAAA in which a custom-designed graft with 3 caudally directed branches was being deployed in a patient who had a prior surgical repair for a type IV TAAA. Two of the branches were successfully cannulated and stented, but repeated efforts to cannulate the left renal branch and artery via the standard brachial approach were unsuccessful.

False aneurysm at the origin of the anterior tibial artery after opening wedge osteotomy.

We report the case of a false aneurysm at the origin of the anterior tibial artery complicating upper tibial osteotomy. The proximally located lesion compressed the posterior tibial nerve, and despite successful decompression, the patient suffers from probably irreversible neurologic after-effects. Even though it is rare, this complication must be considered when faced with leg pain consecutive to upper tibial osteotomy without deep venous thrombosis.
