Spontaneous isolated dissection of the abdominal aorta: single-center experience.

Isolated abdominal aortic dissection is a rare clinical entity. We report a single-center experience with six patients with acute isolated abdominal aortic dissection managed during a period of seven years. The patients' median age was 62 years and they were predominantly male.

Secondary endovascular repair of a reconstructed superior vena cava in a patient with a malignant thymic epithelial neoplasm.

Thymic epithelial tumors can cause venous obstruction from compression or direct invasion of the superior vena cava (SVC) or the innominate veins. We report a case of a 40-year-old patient with a Masaoka stage III thymoma that resulted in obstruction of the left innominate vein and extrinsic compression of the SVC. All macroscopic tumors were resected together with ligation of the left innominate vein and reconstruction of the SVC with an ePTFE graft.

Insertion of long-term tunneled cuffed hemodialysis catheters via the external jugular vein by using a simple, safe and reliable surgical technique.

Objective: Description of our technique for the insertion of long-term tunneled cuffed hemodialysis (HD) catheters via the external jugular vein.

Methods: From December 1999 to August 2006, 357 long-term tunneled cuffed HD catheters were inserted in 308 patients, who were referred to us from various hospitals and clinics in Greece. About half of them (168, or 47%) were inserted via the external jugular vein.

Carotid artery repair after erroneous insertion of a hemodialysis catheter: case report.

The internal jugular vein is increasingly being used as a route for dual-lumen hemodialysis catheter placement. The use of jugular catheters as vascular access for hemodialysis can be associated with serious complications. The most frequent problems are the arterial puncture and haematoma.

ProCol vascular bioprosthesis for vascular access: midterm results.

Background/aims: This study aimed to evaluate the safety and efficacy of the ProCol vascular bioprostheses as vascular access (VA) material, especially in patients with a history of prior failed access.

Methods: During a 20-month period, 25 arteriovenous (AV) bovine vein grafts were placed in 24 hemodialysis (HD) patients for VA. All patients presented with failed autologous access sites.
