HEADINGS Partial hepatectomy. Hepatic metastases. Colorectal cancer. Radiofrequency. Embolization. ABSTRACT – Introduction: Nowadays, liver resections can be performed with acceptable morbi-mortality rates. In specialized centers, mortality as low as 1% can be achieved, even with the advent of new hepatotoxic chemotherapy regimens. In order to reduce morbidity and mortality, newer strategies ca...

mon access for diagnostic and interventional procedures. Potential complications of arterial catheterization are hematomas, arteriovenous fistulas (AVF), pseudoaneurysms, arterial occlusions, and peripheral embolization. The reported incidence of all vascular complications ranged from 1% to 9%, and the incidence of AVF varied from 0.006% to 0.86% (1, 2). An iatrogenic AVF is the result of a com...

BACKGROUND Cuffed, double-lumen, tunneled haemodialysis catheters are a common means of vascular access in paediatric haemodialysis, particularly in infants. Haemodialysis catheter fracture with distal embolization is a rare complication. CASE REPORT A 2-year-old boy was receiving chronic haemodialysis via a right internal jugular cuffed, double-lumen, tunneled haemodialysis catheter, inserte...

A 45-year old female referred for a large carotid body tumor resection. The tumor was encasing the internal (ICA) and external carotid arteries (ECA). She underwent angiogram and embolization of the ascending pharyngeal artery and a distal branch of the ECA using ethylene vinyl-alcohol copolymer (EVOH). Two days later, surgical resection of the tumor with regional lymph node dissection was perf...

Juvenile angiofibromas are benign, vascular, locally aggressive neoplasms that are preferably treated by surgical resection, or irradiation if surgery is not possible. Adequate surgery in the past has been limited by incomplete knowledge of the anatomy of the tumor and technical difficulties related to the vascularity. To better define the tumor, 12 patients with juvenile angiofibroma have been...

PURPOSE To evaluate the safety and efficacy of silk suture as an agent for preoperative embolization of cerebral arteriovenous malformations. METHODS Clinical and histopathologic results were analyzed in six patients who underwent embolization of cerebral arteriovenous malformations using silk suture in combination with other agents. RESULTS Three of the patients treated with silk hemorrhag...

The use of balloon remodeling technique for coil embolization has developed into a safe alternative to stent assisted coil embolization for wide-necked aneurysms. Dual antiplatelet therapy when a stent is placed for assistance in the treatment of ruptured aneurysms is of concern. There are cases in which a single balloon seems insufficient to protect from coil herniation, like when two vessels ...

A 58-year-old man with a medical history of hypertension and hepatocellular carcinoma status after liver transplantation 2 years previously developed head and neck pain. Computed tomography (CT) revealed a contrast enhancing C2 vertebral body metastasis. The highly vascular lesion was embolized prior to surgical resection to minimize surgical complications. The diagnostic angiogram revealed a h...

It is uncommon in medicine for emerging data to completely transform a field, particularly in such a common disease state as atherosclerotic vascular disease. New evidence from multiple fronts has underscored the frequency and prognostic importance of atherosclerotic embolization in the microvasculature. Until recently, we have had limited access to diagnose microvascular obstruction in living ...

PURPOSE To determine (a) whether superselective angioscintigraphy with technetium-99m macroaggregated albumin (99mTc-MAA) can be used for the evaluation of arteriovenous shunting in tumors and vascular malformations of the head and spine and (b) whether the amount of microparticles shunted is related to diagnosis, lesion size, or angiographic pattern. METHODS Particles of 99mTc-MAA with a cal...
