Preoperative embolization for meningeal tumors: evaluation of vascular supply with angio-CT.
نویسندگان
چکیده
When evaluating vascular supply, a combined angiography and CT (angio-CT) system provides more accurate vascular anatomy than digital subtraction angiography. To the best of our knowledge, however, the application for intracranial tumors has not been described. We herein describe a technique of an angio-CT system for diagnosis of vascular anatomy of the feeding artery for preoperative embolization of meningeal tumors.

Carotid body tumors may present with variable clinical symptoms and endocrine dysfunction. E. N. T, vascular and Neuro surgeons are intresting to management of these tumors. Four cases that we describe had palpable neck mass and disocomfort, dysphagia and dizziness. Neuroimaging tests include CT scan, angiography that showed a medium to large size vascular tumor in neck. The mainstay of t...

A 72-year-old male presented with a primary hemangioblastoma of the posterior fossa with unusual dural attachment and meningeal arterial blood supply from the external carotid artery and marginal tentorial artery. Preoperative embolization facilitated complete resection of the tumor with no resultant neurological deficit. Hemangioblastoma must be included in the differential diagnosis of tumors...

BACKGROUND AND PURPOSE Embolization of meningiomas has emerged as a preoperative adjuvant therapy that has proved effective in mitigating blood loss during surgical resection. Arterial supply to these tumors is typically identified by diffuse areas of parenchymal staining after selective x-ray angiograms. We investigate the benefits that selective injection of MR contrast may have in identifyin...
متن کاملPreoperative embolization of intracranial meningiomas with a fibrin glue preparation.
BACKGROUND AND PURPOSE Preoperative embolization expands the spectrum of meningioma that can be operated on safely. Our goal was to achieve the distalmost loading of the vascular bed and confluent tumor necrosis with a fibrin glue preparation in the preoperative embolization of meningiomas. METHODS Between 1992 and 1997, 80 patients with a meningioma had diagnostic angiography with a standard...

Abstract Background Cerebral neoplasm arises from brain, spinal cord and meningeal cells. Not only malignant cerebral neoplasm also benign tumor could lead to death due to mass effect on vital structures. Access to these tumors is difficult, and MRI and CT scan could be helpful in determining anatomical location of tumors and distinction of malignant from benign. Objective For better and ea...
