Prevalent Technique and Results of Hemorrhoidal Embolization.

Hemorrhoids are blood cushions located in the anus and lower rectum, acknowledged as a common cause of bleeding, which can reduce quality of life. The development of minimally invasive techniques such as endovascular embolization of superior rectal artery, "Emborrhoid technique", is an effective treatment, with no pain or ischemic complications, and allows quick patient recovery. Our purpose is to describe the general technique and discuss the results of the current literature.

Cryoplasty versus angioplasty in the treatment of arterial restenosis in an experimental model of atherosclerosis in rabbits.

Cryoplasty may reduce the incidence of post-angioplasty restenosis in peripheral atherosclerotic arteries. Our study is looking to investigate the mid-term effects (4 weeks) of an FDA-approved cryoplasty catheter (PolarCath(®), Boston Scientific) compared to a conventional angioplasty catheter using a hypercholesterolemic rabbit model of arterial restenosis based on diet plus vessel injury. Thirty-six normolipidemic, 3-month old male New Zealand White rabbits were used.

Anatomical variations in the aortic bifurcation in new zealand white rabbits on arteriography.

The radiologic anatomy of the aortic bifurcation in the rabbit has received little study but it is important as this anatomical area is widely used in atherosclerosis research. Thirty rabbits were used to study the aortic bifurcation and subsequent branching patterns on arteriography. Fifteen different arteries were identified.

Intrarenal pseudoaneurysm after percutaneous nephrolithotomy. Renal angiography and selective embolization.

Objective: We present a case of intrarrenal pseudoaneuysm after percutaneous nephrolithotomy. The treatment was selective embolization of the pseudoaneurysm. We discuss the role of computerized angiotomography and angiography in these cases.
