Over a guidewire, the tract is dilated and a large-bore drainage catheter is placed and attached to negative pressure. Because colonic branches are often easy to catheterize rapidly, embolotherapy can be a fast way of obtaining hemostasis. Reviews in journals and word-of-mouth comments have been uniformly favorable. Transjugular liver biopsy in patients with hematologic malignancy and severe thrombocytopenia.

The cases integrate diagnostic, procedural, and periprocedural aspects, simulating the oral board examination and adequately preparing residents for the interventional radiology section of the examination. Angiographic features include enlarged feeding arteries, neovascularity, puddling, dense tumor stain, arterioportal shunting, portal vein invasion, and occasionally hepatic vein invasion. Mesenteric arterial occlusive and aneurysmal disease. Study effectively with content that mimics the format of official exams as well as the everyday clinical experience—offering highly effective preparation for certification, recertification, and practice. While no one book could completely cover the ever-expanding field of interventional radiology, these 170 cases are fairly comprehensive without being onerous.

This usually occurs in association with congenital heart disease, although it occurs rarely as an isolated abnormality associated with situs inversus. Name two potential causes of failure of uterine fibroid embolization. Seroma, hematoma, urinoma, abscess, lymphocele. Comment In the case shown, tight stricturing of the right and left central biliary ducts is evident on cholangiography, and the angiogram demonstrates thrombosis of the transplant hepatic artery that was anastomosed to a native replaced right hepatic artery. What procedure has been performed? The aortic arch passes over the right mainstem bronchus and descends to the right of the esophagus and trachea.
