The embolization of vascular tumors of the head, neck, and CNS has become an important adjunct to the surgical treatment of these tumors. The procedure has resulted in reduced morbidity and mortality and helps to facilitate the removal of many of these tumors. In tumors that are not amenable to surgical therapy, embolization may occasionally be used as the primary mode of treatment. These guide...

Cerebral aneurysms are well known to be associated with cardiac myxomas. The mechanism of cerebral aneurysm formation remains to be elucidated. Embolization of tumor particles in the vessel wall has been proposed as the likely mechanism for aneurysm formation. Recent reports suggest interleukin-6 (IL-6) may play a role as well. We describe a patient who presented with subarachnoid hemorrhage se...

Endoscopic vein harvest in preparation for coronary artery bypass surgery has become a preferred method of procuring saphenous vein. Several case reports have documented carbon dioxide (CO2) embolization with this procedure as well as CO2 embolization during other laparoscopic surgeries (Markar et al., 2010). Although uncommon, the potential for CO2 entrainment through an open vein or through a...

A 73-year-old male with no history of liver disease was hospitalized for weakness, confusion, ataxia, and new onset hepatic encephalopathy with hyperammonemia. After management with lactulose and rifaximin, his symptoms persisted, and he underwent transjugular liver biopsy. Biopsy showed normal liver, but a portosystemic shunt was incidentally identified on postbiopsy venogram. The patient unde...

introduction: to assess the efficacy and safety of bronchial artery embolization in the treatment of massive hemoptysis.   materials and methods: a retrospective study on 46 patients (26 males and 20 females) who were referred to the razavi hospital from april 2009 to may 2012 with massive hemoptysis and had bronchial artery embolization procedures. general characteristics of the patients inclu...

BACKGROUND AND PURPOSE Transarterial embolization of cerebral arteriovenous malformations (AVMs) has been associated with postprocedural neurologic complications in 7-39% of patients. We sought to determine whether a method of targeted neurologic and cognitive testing during AVM embolization reduces the incidence of focal cognitive and other neurologic deficits associated with the procedure. ...

BACKGROUND AND PURPOSE We have developed a new thermosensitive liquid embolic agent, PIB nanogel, that can be solidified at body temperature. We thus further investigated the distribution, durability of vascular occlusion, and inflammatory reactions of PIB in embolization of the renal artery of rabbits. MATERIALS AND METHODS The bilateral renal arteries of 9 rabbits were first embolized with ...

INTRODUCTION Arteriovenous malformations (AVMs) are vascular abnormalities consisting of fistulous connections of arteries and veins without a normal intervening capillary bed. In the cerebral hemispheres, they frequently occur as cone-shaped lesions with the apex of the cone reaching toward the ventricles. Nearly all AVMs are thought to be congenital. Supratentorial location is the most common...

INTRODUCTION An anomalous systemic arterial supply to the normal basal segment without sequestration is a rare congenital vascular malformation. The discovery age is relatively young, and the most common clinical symptom is hemoptysis due to pulmonary hypertension or heart failure. We herein describe a case of endovascular embolization of in an elderly and asymptomatic patient with an anomalous...

22 anesthetized dogs were given a barium sulfate suspension intravenously in a dose sufficient to double mean pulmonary artery pressure. 10 sec breath-holding carbon monoxide diffusing capacity (D(LCO10)) was measured before and after this standard embolization in each dog. No post-embolic decrease in D(LCO10) was observed. In the study of this apparent paradox, it was found that the potential ...
