Recurrent myocardial infarction with patent coronary arteries.

Two separate episodes of severe chest pain occurred several years apart in a 25-year-old male patient with typical clinical findings of acute myocardial infarction with each episode. Cardiac catheterization following the second infarction confirmed the presence of myocardial dysfunction with apical akinesis and dyskinesis. Both coronary arteries were radiologically patent; however, there was evidence of probable recanalization of the right coronary artery.

Transcatheter embolization of an aortocaval fistula caused by residual renal artery stump from previous nephrectomy: a case report.

An arteriovenous fistula between the renal artery and vein is a rare complication of nephrectomy. We report the first case of direct inferior vena cava to renal artery fistula after nephrectomy. In addition, this was the first use of the Amplatz "spider," a vascular obstructing device used to trap coils during transcatheter embolization of a high-flow fistula.

Microcatheter embolization of non-neurologic traumatic vascular lesions.

Purpose: The authors report their experience over a 28-month period with embolization of 23 non-neurologic traumatic vascular lesions in 21 patients with use of a coaxial microcatheter coil delivery system.

Patients And Methods: The injuries included pseudoaneurysms (n = 17), arteriovenous fistulas (n = 3), and sites of extravasation (n = 3) and were caused by gunshot, shotgun, and stab wounds, as well as motor vehicle accidents and iatrogenic trauma. All microcatheter embolizations except one were performed with 2.

Renal artery laceration secondary to percutaneous nephrostomy catheter placement.

Renal artery hemorrhage secondary to placement of percutaneous nephrostomy catheters can lead to major operations and even nephrectomy. We recently treated a woman who suffered a renal artery laceration during percutaneous nephrostomy catheter placement using interventional radiographic techniques. The perforation site was identified using angiography and treated using selective embolization.

Clinical applications of carbon dioxide/digital subtraction arteriography.

During an 18-month period 33 patients in whom there were contraindications to the use of iodinated contrast arteriography underwent 40 carbon dioxide/digital subtraction arteriograms for lower extremity ischemia (19), severe hypertension and renal insufficiency (12), or arterial aneurysm (2). Contraindications to iodinated contrast agents included renal insufficiency, congestive heart failure, and contrast hypersensitivity. Sixteen aortic, 15 iliac-femoral-popliteal-tibial, five aorta-iliac-femoral and four aorta-iliac-femoral-popliteal-tibial carbon dioxide/digital subtraction arteriography studies were performed.
