Embolization may be the primary and exclusive treatment of cerebral arteriovenous malformations. To evaluate its benefits, a group of 27 patients was studied for the incidence of hemorrhages, headaches, seizures, and neurologic deficits, both before and after Silastic sphere embolization. Questionnaires to patients and physicians were used. Embolization was found to decrease the frequency of he...

Tc-99m-DTPA renal scintigraphy was performed before and after transcatheter coil embolization in a patient with renal arteriovenous fistula (AVF). Before embolization, scintigraphy showed a characteristic accumulation pattern compatible with the hemodynamics of an aneurysmal type of AVF in the vascular phase. After embolization, the effects of treatment, such as a change in the split renal func...

Balloon or coil embolization has become established therapy for multiple PAVMs. We were able to evaluate a 32-year-old woman with multiple PAVMs characterized by significant orthodeoxia, intrapulmonary shunt, dyspnea and limited exercise tolerance before and after balloon and coil embolization. After embolization of three of her largest PAVMs, repeat evaluation revealed improvement in her sympt...

Worsening of ocular symptoms in cavernous sinus dural arteriovenous fistulae (CSDAVF) is rarely due to superior ophthalmic vein (SOV) thrombosis after palliative transarterial embolization and may resolve spontaneously. We present a unique case of a 38-year-old female whose ocular symptoms worsened three days after palliative embolization. Repeat angiography revealed incomplete thrombus of SOV ...

Endovascular embolization is being increasingly used to treat intracranial arteriovenous malformations (AVMs). However, we experienced two patients with retained microcatheters after AVM embolization using Onyx.

PURPOSE To evaluate the effectiveness of percutaneous transarterial embolization for the treatment of renal arterial bleeding in patients with renovascular injury. MATERIALS AND METHODS The archives of our angiography suite were retrospectively reviewed, and 15 patients who had undergone renal embolization due to renal artery bleeding were included in the study. The site, number, and type of ...

OBJECTIVE To evaluate the clinical effect of renal artery embolization with a mixture of lipiodol and polyvinyl alcohol (PVA) particles on symptomatic renal angiomyolipoma and to present the mid-term results from our single-center site. METHODS We performed a retrospective review of the seven patients who underwent embolization with a mixture of lipiodol and PVA particles to treat symptomatic...

BACKGROUND AND PURPOSE Provocative testing before AVM embolization has been shown to be a predictor of a successful endovascular treatment without neurologic deficits. Propofol has been used previously as an alternative agent in Wada testing with adequate results. The purpose of this study was to show our experience with the use of propofol as a safe and effective alternative to barbiturate pro...

BACKGROUND AND PURPOSE Precise control of the polymerization dynamics of cyanoacrylate mixtures used in the embolization of cerebral arteriovenous malformations is required to achieve a safe and permanent obliteration of the lesion. In this study, in vivo embolization using mixtures of Histoacryl, Lipiodol Ultra-Fluid, and glacial acetic acid (GAA) was investigated. The present study investigat...

The objective of this study was to evaluate the usefulness of transcatheter arterial embolization prior to surgical excision of musculoskeletal tumors. We reviewed the records of nine patients (3 females and 6 males) who received arterial embolization prior to excision of musculoskeletal tumors in our hospital from December 2009 to April 2010. We evaluated tumor region, size, histopathology, fe...
