Eight balloon dilatations were performed in five patients (aged from 10 to 37 months) in whom supravalvar pulmonary stenosis developed after anatomical correction for complete transposition. The ratio of the maximum diameter of the inflated balloon to the narrowest pulmonary arterial diameter varied from 1.6 to 3.3. In three patients with an initial ratio of less than or equal to 2 dilatation w...

Percutaneous transluminal angioplasty (PTA) is being extensively applied to treat arteriosclerotic lesions. However, this application has not been widely accepted for the treatment of carotid artery stenosis. Successful attempts to relieve cerebral ischemia from extracranial carotid arterial stenosis by PTA are reported. Twenty-seven patients with arteriosclerotic stenosis, fibromuscular diseas...

Introduction: Arterial tortuosity syndrome (ATS), an autosomal recessive rare connective tissue disorder characterized by tortuosity, elongation and stenosis in the large and medium sized arteries. It manifestations include vascular and nonvascular connective tissue related symptoms. In this literature we describe the first cases of ATS from Iran. Case report: A six-months-old female wa...

Isolated basilar artery stenosis (BAS) is a rare etiology of ischemic neurologic conditions. First-line treatment symptomatic typically medical therapy as outlined in the Warfarin–Aspirin Symptomatic Intracranial Disease (WASID) trial and Stenting versus Aggressive Medical Therapy for Arterial Stenosis (SAMMPRIS) trial.1,2 We present case male his 60s with isolated BAS who failed maximal but ex...

The prevalence of carotid and lower extremity arterial disease was assessed in a healthy population of 56 elderly adults with isolated systolic hypertension. Duplex scans were performed to determine the extent of carotid disease, and postexercise ratios of ankle to arm systolic blood pressure were measured to assess lower extremity arterial disease. Internal carotid stenosis was found in 38% (2...

OBJECTIVE Prevention is the best treatment for cerebrovascular disease, which is why early diagnosis and the immediate treatment of carotid stenosis contribute significantly to reducing the incidence of stroke. Given its silent nature, 80% of stroke cases occur in asymptomatic individuals, emphasizing the importance of screening individuals with carotid stenosis and identifying high-risk groups...

BACKGROUND AND OBJECTIVES Pulmonary arterial stenosis is a relatively common complication after corrective operation of congenital heart disease. Unilateral stenosis of pulmonary arteries could result in decrease perfusion of affected lung, pulmonary regurgitation, or elevation of right ventricular pressure. Eventually there are increasing risks of right ventricular failure, arrhythmia, or sudd...
