abstract symptomatic basilar artery stenosis has a poor prognosis. surgical bypasses are technically demanding and of no proven benefit. a new generation of intravascular stents that are flexible enough to navigate the tortuosities of the vertebral artery may provide a new therapeutic approach. our two cases, 57 and 52 year-old men experienced a vertebrobasilar ischemia with repeated vertigo an...
transluminal balloon valvuloplasty is an alternative to surgical valvotomy for congenital pulmonary valve stenosis. the aim of this study was to evaluate the long term results (to 13.5 years) of balloon pulmonary valvuloplasty. from june 1998 to january 2012, percutaneous balloon pulmonary valvuloplasty for congenital pulmonary valve stenosis was performed in 98 patients (50 males, 48 females, ...
conclusions our findings revealed that the severity of coronary artery stenosis is common in diabetic patients compared to nondiabetics. early diagnosis and treatment of cad in diabetic patients is recommended. results based on data found in our study, 93.8% of diabetic and 83.4% of nondiabetic patients were shown to suffer coronary artery stenosis. severe involvement (grade 3vd) of coronary ar...
Nephrotic syndrome is a rare manifestation of renal artery stenosis, presented mainly in adulthood. This is the report of a 4 months old boy admitted for hypertension and nephrotic syndrome. Left renal artery stenosis and renal hypoplasia were documented by laboratory and imaging studies. Proteinuria improved with medical treatment, with no need to surgical repair. Blood pressure remained norma...
successful implantation of coronary sinus lead after balloon angioplasty of a coronary vein stenosis
a 55-year-old man referred for cardiac resynchronization therapy (crt) due to severe heart failure. a severe stenosis in the coronary sinus vein after the posterior branch disallowed the insertion of the lead. nevertheless, the stenosis was dilated and the left ventricle (lv) lead was implanted in the lateral marginal branch.
ABSTRACT Renal artery stenosis is one of the treatable causes of systemic hypertension in children. For years surgery was the treatment of choice, but recently PTRA (Percutaneous Transluminal Renal Angioplasty) has been successfully performed for relief of the stenosis. This method compared with surgery is safe, simple and has lower complication rate. At times stent placement is performed in co...
In this paper pulsatile laminar blood flow in an axisymmetric stenosed tube is simulated by the Non-Newtonian Power law model. Effect of stenosis, for severe condition of 75% reduction of local area was considered and the flow patterns for three Womersley numbers were studied. The results show that there is a fundamental difference in the flow pattern at . This difference is related to second c...
Kindler syndrome (KS) is a rare autosomal recessive genodermatosis. We report two cases of KS with classical clinical presentations involving skin and mucus membranes. Clinically, both patients had four major features of KS in the form of acral skin blistering, photosensitivity, progressive poikiloderma, and diffuse cutaneous atrophy. Case 1 had associated features in the form of urethral...
Study Design Retrospective study. Objective Studies on age-related degenerative changes causing concurrent stenoses in the cervical, thoracic, and lumbar spines (triple stenosis) are rare in the literature. Our objectives were to determine: (1) the incidence of asymptomatic radiologic cervical and thoracic stenosis in elderly patients with symptomatic lumbar stenosis, (2) the incidence of concu...
