The aortic arch presents specific challenges to endovascular repair. Hybrid repair is increasingly evolving as an alternative option for selected patients, and promising initial results have been reported. The aim of this study was to introduce our experiences and evaluate mid-term results of supra aortic transpositions for extended endovascular repair of aortic arch pathologies. From December ...

Type II chronic dissecting thoracoabdominal aortic aneurysms are a surgically challenging disease. The conventional thoracoabdominal aortic aneurysm repair technique using cardiopulmonary bypass is a high-risk procedure. However, a recently developed endovascular technique may be an alternative treatment for the disease, but faces the obstacle of lesional restriction. This new technique uses a ...

OBJECTIVE Guglielmi detachable coil embolization of cerebral aneurysms is becoming increasingly used to manage certain intracranial lesions based on aneurysm geometry, patient condition, and patient and surgeon preferences. Aneurysm recurrences or incomplete initial treatments are not uncommon, making repeat treatment necessary using either surgical or endovascular techniques. METHODS Between...

PURPOSE To evaluate the safety of endovascular treatment of chronic cerebrovascular insufficiency (CCSVI) in patients with multiple sclerosis (MS). METHODS In a 1-year period, 461 MS patients (261 women; mean age 45.4 years, range 21-79) with CCSVI underwent endovascular treatment of 1012 venous lesions during 495 procedures [34 (6.9%) reinterventions]. While balloon angioplasty was preferred...

OBJECTIVE To describe and analyze the results of a public-private partnership between the Ministry of Health and a private hospital in a project of assistance and scientific research in the field of endovascular surgery. METHODS The flows, costs and clinical outcomes of patients treated in a the public-private partnership between April 2012 and July 2013 were analyzed. All patients underwent ...

Objective The cause of severe clinical vasospasm after aneurysmal subarachnoid hemorrhage remains unknown, despite extensive research over the past 30 years. However, the intra-arterial administration of vasodilating agents and balloon angioplasty have been successfully used in severe refractory cerebral vasospasm. Materials and Methods We retrospectively analyzed the data of 233 patients adm...

BACKGROUND AND PURPOSE Cerebral vasospasm remains a major problem in patients recovering from aneurysmal subarachnoid hemorrhage despite advances in medical, surgical, and endovascular care. Our purpose was to assess the efficacy of intra-arterial nimodipine, a calcium-channel blocker acting mainly on cerebral vessels, in preventing delayed neurologic deficits in patients with symptomatic vasos...

Introduction: Endovascular procedures in emergencies like the implantation of tubes for a life support system are increasing. Guidewires essential basis regularly used Seldinger Technique. We present novel concept that may further optimize safety and efficacy guidewire handling navigation during endovascular procedures. Method: Using specifically designed luminescent particles, novel, clinical-...

BACKGROUND The prevalence of pulmonary hypertension is unusually high in Taiwanese patients with end-stage renal disease. Thrombosis of hemodialysis grafts is common and pulmonary embolism has been reported after endovascular thrombectomy. The aim of this study was to evaluate the relationship between pulmonary hypertension and endovascular thrombectomy of hemodialysis grafts. METHODS One hun...

OBJECTIVES We evaluated the anatomic and technical factors predicting stent malposition and embolization in patients undergoing endovascular stent implantation for relief of noncoronary vascular obstruction. BACKGROUND Endovascular stent implantation provides a highly effective, minimally invasive solution to vascular obstruction in patients with structural heart disease. However, stent impla...
