Primary endovascular stent placement for focal infrarenal aortic stenosis: long-term results.

Purpose: The objectives of this retrospective study were to determine the technical success, safety, and long-term results of primary stent implantation in infrarenal aortic stenosis.

Materials And Methods: A total of eight atherosclerotic stenoses and one occlusion of the infrarenal aorta (ie, midaortic syndrome) were treated with endoluminal stent placement after balloon angioplasty. Aortoiliac lesions were excluded.

Long-term results after primary stenting of distal aortic stenosis.

Purpose: To review the long-term results of primary stent placement in the distal aorta above the bifurcation.

Methods: Fourteen patients (8 men; mean age 62 years, range 46-82) underwent primary stent implantation performed by an interdisciplinary radiosurgical team. In 10 patients, a long-term follow-up examination consisting of patient history, clinical examination, and duplex sonography was performed.

Primary endovascular stent placement for focal infrarenal aortic stenosis: initial and midterm results.

The objectives of this retrospective study were to determine the technical success, safety, and midterm results of primary stent placement of infrarenal aortic stenosis. Eight stenoses and one occlusion were treated with stent placement after balloon pre-dilation. Primary technical success was achieved in all patients.

Comparison of the vasodilating effect of nitroglycerin, verapamil, and tolazoline in hand angiography.

Purpose: To compare the vasodilating effect and safety of intraarterial verapamil with the long-accepted standard vasodilators nitroglycerin and tolazoline in hand angiography.

Materials And Methods: The authors studied 25 patients who underwent brachial artery angiography. In 22 cases, there was poor or moderate visualization of the forearm and hand vasculature.
