The embolization of vascular tumours the head and neck has become an important adjunct to surgical treatment these tumours. A tumour in region a surgically treatable patient may be candidate for embolization. Palliative sole high risk patients. Reducing intraoperative bleeding shorten surgery time thus decreasing morbidity mortality. purpose this study is assess efficacy as or curative measure management hypervascular We retrospectively reviewed records 46 consecutive patients (27 men 16...

Background: Scalp is the most common site of soft tissue arteriovenous fistulae and surgical excision has been primary mode treatment. Endovascular treatment evolved as an alternative to surgery. Aims: To evaluate effectiveness percutaneous direct-puncture embolization cirsoid aneurysms. Materials Methods: From January 1995 December 2004, 15 patients underwent Plain X-ray, computerized tomography scan complete selective cerebral angiogram were done in all. Seven had forehead lesions, four...

Background and Purpose: The role of carotid artery stenting (CAS) as an alternative to endarterectomy in the treatment for symptomatic stenosis is investigated. Materials Methods: Forty-seven patients underwent CAS over 10-year period. Forty-nine vessels were treated. Stenosis quantification was done using North American trial method. mean follow-up period by clinical Duplex examination ranged 5.6 years. Results: technical success rate 100%. There four deaths (8.1%) two (4.1%) minor strokes...

Purpose: Intracranial mycotic aneurysms (IMAs), rare and often life-threatening, result from arterial wall infections typically caused by bacteria such as Staphylococcus Streptococcus. The standard treatment for ruptured is not well-defined individualized. This study investigates the efficacy of endovascular glue embolization in managing IMAs, based on our center’s experience.Materials Methods: A retrospective analysis was conducted IMAs treated with between January 2016 December 2023....
