We sought to demonstrate the technical aspects of atypical arteriovenous graft (AVG) creation for hemodialysis in a patient with multiple previous failed attempts at vascular access. A 38-year-old female diabetes and dialysis access was referred our center. Preoperative duplex ultrasound venography showed patent central venous outflow, no sufficient superficial conduit, poor arterial inflow hig...

BACKGROUND Inferior vena cava (IVC) leiomyosarcoma is a rare tumor of smooth muscle origin. It is often large by the time of diagnosis and may involve adjacent organs. A margin-free resection may be curative, but the resection must involve the tumor en bloc with the affected segment of vena cava and locally involved organs. IVC resection often requires vascular reconstruction, which can be done...

BACKGROUND Biologic prosthesis (BP) has been reported as a safe alternative to polytetrafluoroethylene (PTFE) in vascular reconstruction. However, efficacy of BP remains controversial. We, therefore, conducted a systematic review to summarize previous available evidences comparing the BP and PTFE in terms of clinical outcomes. MATERIALS AND METHODS A literature search of the MEDLINE and Scopu...

Between June 1978 and January 1982, 115 patients underwent 122 subclavian artery-pulmonary artery shunts using polytetrafluoroethylene (PTFE Impra) grafts. Forty-six of the patients had a ductus dependent pulmonary circulation, the patency of which was maintained by an infusion of prostaglandin E2 in 29 cases. There were nine hospital deaths, four of which were related to shunt failure. Five pa...

A left-sided interposition graft (modified Blalock-Taussig anastomosis) was constructed with polytetrafluoroethylene in a three month old child with tetralogy of Fallot. This shunt thrombosed and a replacement shunt became the site of chronic Pseudomonas infection. The second anastomosis was excised and a third interposition graft was inserted on the right side because the anatomy was unsuitabl...

Abstract The interface incompatibility between organic polymer and inorganic ceramic filler is a common phenomenon in polymer-based dielectric composites. In this paper, the Ar/CF 4 plasma used to modify CaTiO 3 particles, which improved dispersion of its compatibility with polytetrafluoroethylene (PTFE). findings demonstrate that growing argon (Ar) flow rate was beneficial enhance discharge in...

Herein, we report two extremely rare cases of differentiated thyroid carcinoma (DTC) with extended tumor thrombus or mediastinum lymph node metastasis (LNM) involving the superior vena cava (SVC), causing SVC syndrome. Both of these patients were successfully treated with radical resection and reconstruction of the SVC using autologous tissue instead of an expanded polytetrafluoroethylene (ePTF...

An inferior mesenteric artery (IMA) aneurysm is the rarest among visceral artery aneurysms. A 69-year-old man was referred to our hospital with an asymptomatic IMA aneurysm associated with occlusion of the superior mesenteric artery (SMA) and celiac artery (CA). After revascularization of the SMA with an 8-mm expanded polytetrafluoroethylene (ePTFE) graft, the aneurysm was resected, and the IMA...

INTRODUCTION Popliteal artery aneurysms are the most common peripheral arterial aneurysms, and are frequently bilateral. Acute limb ischemia, rupture and compression phenomena can complicate these aneurysms when the diameter exceeds 2 cm. CASE PRESENTATION We report an 82-year-old male patient with two giant femoropopliteal aneurysms, 10.5 and 8.5 cm diameters, managed in our institution. Bot...

A 2-year-old male mixed dog was referred to us for further evaluation and treatment of a 4-week-history of oliguria and abdominal distension after a surgical repair of urethral injury. To relieve the urethral stricture, we placed a self-expanding aortic stent graft extension with a partial coverage with an expanded polytetrafluoroethylene (ePTFE). After the placement of the stent, the dog prese...
