Carotid Bypass Using Gore Hybrid Vascular Graft for In-stent Restenosis after Carotid Stenting.

In-stent restenosis (ISR) is the most common long-term complication following carotid artery stenting (CAS), affecting 3.5% to 21% of patients after a mean follow-up of 18 months in published reports. Until now, the optimal management for ISR after CAS is still not clear, and different endovascular treatments along with various surgical options have been proposed. Moreover, surgical treatment for ISR in a previously operated patient of ipsilateral endarterectomy is a technically demanding procedure. In this report, we describe a case of severe carotid recurrent ISR, which occurred after CAS for postendarterectomy restenosis, that was successfully treated, in a straightforward way, with a carotid bypass using a Gore® Hybrid Vascular Graft.

"Two is better than one": a composite graft made of two different vascular prostheses for urgent hemodialysis access in a troublesome case.

BACKGROUND: Multiple failed hemodialysis access and poor vascular anatomy can jeopardize an end-stage renal disease patient's survival, frequently leading to the urgent need for rapid and durable new vascular access. In these circumstances, the extensive use of central venous catheters (CVC) can led to serious complications, such as infection, thrombosis, and often vessel scarring with obstruction of the central veins. More recently, new self-sealing prosthetic grafts may be cannulated within a few days after implantation, avoiding the need for extensive CVC. However, similar to all synthetic arteriovenous grafts (AVG), the new grafts are prone to rapid and aggressive venous neointimal hyperplasia (VNH), which is responsible for outflow stenosis and access thrombosis. Endoluminal sutureless anastomosis has been demonstrated to have better hemodynamics at the venous outflow with a supposed reduction of VNH, thus potentially improving graft patency. METHODS: We report a case of a successful creation of a composite prosthetic access in a patient with severe comorbidities and nearly complete exhaustion of all vascular sites and with the need for immediate access for hemodialysis. Two relatively novel vascular expanded polytetrafluoroethylene prostheses were used jointly in this patient for a brachial-axillary AVG to allow early cannulation and with the aim of being less vulnerable to outflow stenosis. A multilayer self-sealing graft and a graft with a nitinol reinforced section, which permits endoluminal sutureless anastomosis, were sewed together to create a unique prosthesis with both features. RESULTS: The composite graft was cannulated 48 hr after implantation and continued to function well at 10 months of follow-up without signs of venous stenosis. CONCLUSIONS: This simple technique allows the creation of a customized composite graft with self-sealing properties and improved hemodynamics at the venous outflow.

Extra-anatomic lateral bypass combined with embolization of the femoral stump for management of groin infection and bleeding due to metastatic carcinoma of the penis.

We report a possible treatment strategy for a patient with squamous cell carcinoma of the penis in hemorrhagic shock, due to erosion of the right femoral artery by metastatic inguinal lymph nodes. Because of coexistent groin infection and the inability to perform radical excision, the patient was treated with a lateral extra-anatomic iliac femoral prosthetic bypass; to prevent further bleeding, the femoral stump was embolized percutaneously. The patient was discharged home and did not experience any vascular complications during the follow-up, until death due to pulmonary metastasis.
