BACKGROUND Renal artery stenosis (RAS) is a common finding in patients undergoing coronary angiography. We designed this study to look for the frequency and any predictors of renal artery stenosis in patients with coronary artery disease (CAD). METHODS A total of 201 consecutive patients with CAD confirmed by coronary angiography underwent an abdominal aortogram in the same sitting to screen ...

The causes leading to the exacerbation of preexisting chronic heart failure can be various. Renal artery stenosis is an important cause of renal dysfunction, and can lead to worsening of heart failure and increased mortality. We present a 49-year old male patient after acute myocardial infarction, heart failure with left ventricle ejection fraction of 20%, permanent atrial flutter, peripheral v...

RATIONALE Neurofibromatosis type 1 (NF-1) is an autosomal dominant disorder characterized by cafe au lait macules and neurofibromatosis. Renal artery aneurysms are relatively uncommon. Endovascular techniques are effective in treating renal aneurysms but successful cases are rarely reported in NF-1 adults. PATIENT CONCERNS The patient was one 23-year-old female presented with hypertension, mu...

introduction: the persian squirrel (sciurus anomalus) is considered the only well-known species of the family sciuridae in the middle east. since some people keep this squirrel as a domestic pet, their attendance at veterinary clinics is increasing. so far, no study has been conducted on the arterial supply of the pelvic cavity and limb in the squirrel. hence, this research was performed to fil...

PURPOSE To determine angiographically the origins and variations of renal arteries. MATERIALS AND METHODS The study included 855 consecutive patients (163 females, 692 males; mean age, 61 years) living in the Cukurova region of Turkey, who underwent either aortofemoropopliteal (AFP) angiography for the investigation of peripheral arterial disease, or renal angiography for renovascular hyperte...

The role of angiotensin II (All) in pressor hyperresponsiveness was examined in conscious one-kidney, one clip rabbits with renal artery stenosis 01 3-days' duration (renal prehypertensive rabbits). Conscious one-kidney rabbits without renal artery stenosis served as controls. Two experiments were performed. The first experiment used four groups of six rabbits each, to examine the pressor respo...

A 24-year-old man with end-stage renal disease secondary to congenital renal hypoplasia under-went a preemptive renal transplant. Although a vascular complication occurred during surgery, the operation was completed satisfactorily. However, postoperative Doppler ultrasound showed no perfusion of the renal artery, vein, and parenchyma, indicating a transplant renal artery thrombosis. A reoperati...

OBJECTIVE The aim of this study was to evaluate the foetal renal blood flow with colour Doppler ultrasonography. Patients with polyhydramnios were investigated for the foetal renal artery pulsatility index (PI) at the beginning of the treatment, and after the conservative treatment in those who reached the normal amniotic fluid index. MATERIALS AND METHODS In this prospective study, 39 foetus...
