BACKGROUND The preferred treatment for intracranial hemangioblastomas is surgical resection with or without preoperative embolization, however, embolization remains controversial due to risks such as distal tip entrapment, vascular injury during navigation, and embolic agent migration. CASE DESCRIPTION A 54-year-old woman was admitted for surgical resection and preoperative embolization of a ...

Advancement in microcatheter design and emergence of new embolic agents offer better results in endovascular treatment of brain arteriovenous malformations (AVMs). Precipitating hydrophobic injectable liquid (PHIL) (Microvention) is a newly introduced dimethyl sulfoxide-based embolic agent for endovascular use. Herein, we present three patients who underwent endovascular treatment of brain AVMs...

BACKGROUND AND PURPOSE Previous studies have suggested embolic mechanisms for bihemispheric subcortical infarcts involving the anterior and posterior circulation. However, the mechanism of bihemispheric subcortical infarcts in middle cerebral artery (MCA) territories remains uncertain. We describe a patient with acute bihemispheric subcortical infarcts in restricted MCA territories suggesting a...

Intravascular embolism has become the major means for treating intracranial aneurysm, cerebral arteriovenous malformation and arteriovenous fistula. With the development of mechanical embolic materials, especially mechanical detachable tungsten filament micro spiral, guglielmi datacbcble micro coil and other controlled micro spiral techniques, intracranial aneurysms can almost achieve the same ...

A scrotal arteriovenous malformation (AVM) is a rare condition representing an abnormal connection between the arterial and venous systems of vessels supplying the scrotum. Scrotal AVMs are usually treated via transcatheter embolization, surgical extirpation, or a combination of the two approaches. A 41-year-old man developed a life-threatening hemorrhage from a scrotal AVM. After hemodynamic s...

PURPOSE To evaluate the effects of fat embolism in organs such as lung and liver. METHODS Twenty rabbits underwent autologous intramuscular fat grafting in the right thigh after liposuction. The groups were determined according to the postoperative day that occurred in euthanasia: 60, 90 and 120 day. Then, lung and liver were excised and sent to the histopathology laboratory for analysis in s...

Three patients with spontaneous dural carotid-cavernous fistulas were treated by using a combination of detachable coils and Onyx liquid embolic agent. Cavernous sinus was accessed via the superior ophthalmic vein or inferior petrous sinus approach. In all cases, a complete angiographic closure of the fistulas was achieved with full recovery from neuro-ophthalmologic symptoms. This report sugge...

The relationship between recovery from aphasia and regional cerebral blood flow (CBF) was compared in 87 patients, 44 with cerebral hemorrhage and 43 with non-embolic cerebral infarction. CBF values correlated poorly with aphasia outcome in patients with cerebral hemorrhage whereas a tight correlation was demonstrated in patients with non-embolic cerebral infarction. A marked variability of CBF...

In a literature review, the incidence and morbidity of bleeding complications after dental surgery in anticoagulated patients was compared with embolic complications when anticoagulation was interrupted. Over 99% of anticoagulated patients had no postoperative bleeding that required more than local hemostatic measures. Of more than 5431 patients undergoing more than 11,381 surgical procedures, ...
