TEVAR and EVAR, the unknown knowns of the cardiovascular hemodynamics; and the immediate and long-term consequences of fabric material on major adverse clinical outcome.

This review discusses the impact of endovascular aneurysm repair on cardiovascular (CV) hemodynamics and the role of stent-graft material, i.e., polytetrafluoroethylene (PTFE) vs.

Combined thoracic endovascular aortic repair and endovascular aneurysm repair and the long-term consequences of altered cardiovascular haemodynamics on morbidity and mortality: case series and literature review.

Background: Thoracic and abdominal aortic stent grafts are firmer and more rigid than the native aorta. Aortic implanted devices have been implicated in the development of acute systolic hypertension, elevated pulse pressure, and reduced coronary perfusion.

Case Summary: We report four cases of staged thoracic endovascular aortic repair (TEVAR) and then endovascular aneurysm repair (EVAR).

Hydration may reverse most symptoms of lower extremity intermittent claudication or rest pain.

Background: Medical treatment of severe intermittent claudication or critical limb-threatening ischemia causing rest pain frequently achieves only partial relief or is not effective at all.

Methods: Patients with severe intermittent claudication or rest pain of the lower extremities who did not improve after control of risk factors, supervised exercises, and cilostazol medication were included in this study. All patients were treated with hydration.

Reversal of Lower-Extremity Intermittent Claudication and Rest Pain by Hydration.

Background: Medical treatment of disabling intermittent claudication or critical limb-threatening ischemia causing rest pain often fails or has partial response.

Methods: In this pilot study, 36 patients (12 females) affected by disabling intermittent claudication or rest pain of the lower extremities were exposed to a daily 3-L water intake for up to 6 weeks. Cutaneous foot temperature, ankle/brachial index, time and distance of claudication, and pain intensity were recorded before and at the completion of the hydration period.

Stent-graft treatment of pseudoaneurysms and arteriovenous fistulae in the carotid artery.

The purpose of this study was to assess the safety and efficacy of stent-graft placement in the management of arteriovenous fistulae (AVF) and pseudoaneurysms (PAs) involving the carotid artery (CA). Twenty-two patients (16 men, 6 women) with a CA AVF (n = 5) or PA (n = 17) owing to a gunshot or stab wound, carotid endarterectomy, blunt trauma, a tumor, spontaneous dissection, or a central venous catheter were treated with percutaneous placement of stent grafts. The patients presented with tumor, bruit, headache, mouth and tracheostomy bleeding, transitory hemiparesis, seizure, or stroke.

General utilities of multislice tomography in the cardiac field.

Objects: To show all cardiac evaluations multislice computed tomography (MSCT) can perform.

Methods: MSCTs were performed on an MSCT scanner (Mx8000; Philips Medical Systems) with enhanced contrast acquisition. The reconstructed images were sent to a workstation for multiplanar reconstruction, volume rendering, and 3-D reconstruction.

Endovascular treatment of aneurysmal disease.

Endovascular repair of abdominal aortic aneurysm using stent grafts that are delivered intraluminally by catheters is a less invasive alternative to open surgical repair. Endovascular surgery has been studied for over a decade, and early results are comparable to open repair. With extended follow-up care, however, postoperative complications and graft failures have been reported in some patients, resulting in reintervention, conversion to open repair, and death.

Safety maneuvers to prevent embolism complicating endovascular aortic repair.

The endoluminal approach of the diffusely atheromatous aorta (DAA) is an emerging tool to prevent further embolization. We treated one symptomatic patient with DAA. We designed a catheter with a balloon at the tip for occlusion of both common iliac arteries through which the antegrade flow was allowed by an iliac to femoral arterio-arterial shunt connected to an in-line filter.
