Compliance mismatch between stent graft and host artery may induce complications and blood flow disorders. However, few studies have been reported on stent graft compliance. This study aims to explore the deformation and compliance of stent graft in stented and unstented zones under three pressure ranges. Compliance of two stent grafts incorporated with polyurethane graft (nitinol-PU) and polye...

Background: There have been reports on stent-related vascular erosions about patients with benign or malignant stenosis of the esophagus who received endoscopic stent insertion for palliative intention for oral intake. Case presentation: A 61-year-old woman with esophageal cancer located in the middle part of esophagus was treated with esophagectomy. Two years following the surgery, malignan...

A 70-year-old man, who had undergone the placement of an endovascular aneurysm repair graft for an abdominal aortic aneurysm 7 years previously, presented to our facility with the separation of a left iliac stent-graft limb from the main-body stent-graft, resulting in a type III endoleak. An attempt was made to repair the disconnected stent-graft limb with endovascular intervention. An extensio...

OBJECTIVES Thoracic endovascular aortic repair (TEVAR) has been shown to lead to increased aortic stiffness. The aim of this study was to investigate the effect of stent graft type and stent graft length on aortic stiffness in a controlled, experimental setting. METHODS Twenty porcine thoracic aortas were connected to a pulsatile mock loop system. Intraluminal pressure was recorded at two sit...

INTRODUCTION The results of endovascular stent-grafts in the abdominal aorta and descending thoracic aorta have been encouraging. Expanding the use of thoracic stent-grafts in to the aortic arch has been associated with increasing numbers of complications. Recently isolated cases of stent-graft collapse have been reported. METHODS This was a multi-centre European case series. Data was collect...

PURPOSE The purpose of this study was to determine whether radiographically demonstrated proximal stent graft contour can be used as a marker for security of proximal neck fixation after endovascular aneurysm repair. METHODS Stent graft structure was examined in 100 consecutive patients with abdominal aortic aneurysms who were treated with the stent graft. Stent graft integrity, stent contour...

OBJECTIVE We evaluated the effect of close contact between the stent and the graft on the induction of endothelial covering on the stent graft placed over an aneurysm. MATERIALS AND METHODS Saccular abdominal aortic aneurysms were made with Dacron patch in eight dogs. The stent graft consisted of an inner stent, a expanded polytetrafluoroethylene graft, and an outer stent. After sacrificing t...

Open stent-graft has been used in the treatment of aortic dissection in recent years. Two device related complications happened in two patients. One was stenosis of the true lumen in the descending aorta caused by infolding of the distal end of the stent-graft immediately after its deployment. The other one was a new intima tear at the distal end of the stent-graft caused by full expansion of t...

Abstract Background A tracheo-innominate fistula is a rare but life-threatening complication of tracheostomy and has mortality rate 100% without therapy. The underlying cause an acquired between the brachiocephalic trunk trachea, induced by cannula’s mechanical impact. Case presentation 25-year-old female was admitted with pulsatile bleeding from tracheostomy. artery fistula, which difficult to...
