BACKGROUND Despite increasing acceptance of endovascular coiling for treating anterior communicating artery (ACoA) aneurysms, anterior circulation cerebral infarction (ACI) after embolization remains a limitation. With higher incidence, higher morbidity and higher mortality, it is one of the main factors influencing the ACoA aneurysms prognosis. Determining the risk factors leading to ACI after...
BACKGROUND Preoperative uterine artery embolization has been shown to help reduce blood loss, with few complications. Most reports indicated that uterine artery embolization is safe for uterine fibrosis; the occurrence of hyperkalemia and acute kidney failure as complications of preoperative uterine artery embolization has not been reported previously. Here we report the occurrence of hyperkale...
To evaluate whether the efficacy and safety of embolization of the aneurysmal neck were better than those of embolization of the entire aneurysm. Previous studies found that embolization of the aneurysmal neck can be used for treating ruptured intracranial aneurysm with bleb formation.In all, 163 patients with ruptured aneurysms with bleb formation who underwent endovascular embolization at the...
PURPOSE OF REVIEW The management of uterine fibroids in patients requiring treatment who desire future fertility remains controversial. Myomectomy has been the most common operative procedure to improve pregnancy rates and outcomes. Uterine fibroid embolization is an increasingly popular, minimally invasive treatment for fibroids. This review aims to provide critical analysis of available data ...
Embolization of a percutaneous patent foramen ovale (PFO) closure device is a rare but serious complication. While early, periprocedural device embolization can normally be managed with snare and percutaneous retrieval, late embolization requires a different management strategy due to inability of the device to deform to allow passage into a large caliber sheath. We present a case of asymptomat...
We report the first use of Onyx in the embolization of spinal tumors in 2 cases of aggressive vertebral hemangioma. In both cases, Onyx embolization provided effective preoperative tumor devascularization after the initial prolonged particulate embolization with Embospheres made little overall impact. Onyx enables a more rapid and visible embolization than particles and is less technically dema...
To determine whether PHEMA [poly(2-hydroxyethylmethacrylate)] is suitable for portal vein embolization in patients scheduled to right hepatectomy and whether it is as effective as the currently used agent (a histoacryl/lipiodol mixture). Two groups of nine patients each scheduled for extended right hepatectomy for primary or secondary hepatic tumor, had right portal vein embolization in an effo...
PURPOSE Angiographic finding including venous drainage pattern should be correlated to the presenting symptom pattern (SxP) in CSDAVF. We present outcome of CSDAVF management and suggest a strategy according to SxP and type of treatment based on our experience. MATERIALS AND METHODS We evaluated SxP, angiographic type (proliferative, restrictive or late restrictive), mode of treatment (emboli...
BACKGROUND AND PURPOSE Endovascular treatment with cyanoacrylate embolization is an option when complete obliteration of the nidus of an intracranial arteriovenous malformation (AVM) is the goal. Our purpose was to evaluate the rates of initial success and permanent cure of such treatment in a Chinese population. METHODS Twenty-seven consecutive patients with an intracranial AVM underwent end...
PURPOSE To describe the pattern and time course of embolization-related tissue lesions and repermeation of the intranidal cast after endovascular embolization of cerebral arteriovenous malformations (AVMs) with N-butyl cyanoacrylate (NBCA). METHODS We retrospectively reviewed the records of 26 patients who were treated by endovascular embolization with NBCA and subsequent surgical extirpation...
