In coronary artery bypass grafting, a diffusely diseased left anterior descending coronary artery (LAD) is an obstacle to achieving complete revascularization, consequently leading to the possibility of a poor prognosis. Long segmental reconstruction with or without endarterectomy is a revascularization method for treating diffusely diseased coronary arteries. Herein, we report a successful cas...

Background: Carotid artery stenting (CAS) has recently been recommended as an alternative to carotid endarterectomy (CEA) by some clinicians. Objective: This study was designed to evaluate the success rate and in-hospital and 30-day adverse events in our first experiences in Iran for CAS with protection devices, to document our results and guide further use of CAS. Methods: From December 2...

BACKGROUND In the Carotid and Vertebral Artery Transluminal Angioplasty Study (CAVATAS), early recurrent carotid stenosis was more common in patients assigned to endovascular treatment than it was in patients assigned to endarterectomy (CEA), raising concerns about the long-term effectiveness of endovascular treatment. We aimed to investigate the long-term risks of restenosis in patients includ...

BACKGROUND Findings from randomised trials have shown a higher early risk of stroke after carotid artery stenting than after carotid endarterectomy. We assessed whether white-matter lesions affect the perioperative risk of stroke in patients treated with carotid artery stenting versus carotid endarterectomy. METHODS Patients with symptomatic carotid artery stenosis included in the Internation...

Chronic thromboembolic pulmonary hypertension (CTEPH) can be defined as pulmonary hypertension with persistent pulmonary perfusion defects causes by unresolved thrombi. All symptomatic CTEPH patients with documented pulmonary vascular resistance > 300 dyn*sec*cm(-5) and proximal lesions should be considered for surgical treatment--pulmonary endarterectomy. The role of pharmacological treatment ...

Tandem arteriosclerotic lesions of the carotid sinus and siphon increase the risks of carotid endarterectomy; when the siphon is severely stenotic, a microvascular bypass may be the preferable procedure. Two patients, each with severe siphon stenosis and significant sinus lesions, however, were subjected to carotid endarterectomy as their initial surgical procedure. The postoperative arteriogra...

Current reimbursement guidelines from the Centers for Medicare & Medicaid Services, prior to the publication of the Carotid Revascularization Endarterectomy Versus Stenting Trial (CREST) results, reserve carotid artery stenting for stenosis in patients who are symptomatic, with severe stenosis, and considered high risk for carotid endarterectomy (CEA). CREST is a prospective, multicenter, rando...
