title: Phentolamine for enhanced visualization of distal arteries in lower extremity arteriography.
abstract: To augment visualization of the distal arteries, phentolamine was administered to 83 patients (164 limbs) undergoing lower extremity arteriography. Arterial visualization was graded into three classes and skin temperatures were recorded. Phentolamine provided very good visualization of the distal arterial bed in 95% of limbs. A strong correlation was observed between the temperature rise of the feet and the class of arterial visualization. No side effects were recorded. The use of phentolamine in lower extremity arteriography is recommended.
