Between 1926-36 Norman Dott managed 39 patients with suspected intracranial haemorrhage. During this period he established important principles of diagnosis and developed new methods for the medical and surgical treatment of aneurysmal subarachnoid haemorrhage. Dott performed the first intracranial operation to treat an aneurysm and the first angiogram to demonstrate an intracranial aneurysm. T...

BACKGROUND AND PURPOSE To improve the safety and efficacy of liquid embolization, we evaluated changes in pressures in experimental aneurysms. METHODS We created three replicas of a lateral sidewall aneurysm and placed them in a physiologic flow circuit. A 3 x 10-mm nondetachable balloon was positioned in the parent vessel across the aneurysmal neck. Intra-aneurysmal pressures were measured a...

BACKGROUND AND PURPOSE We have previously demonstrated that the local delivery of monocyte chemotactic protein-1 (MCP-1) via an MCP-1-releasing poly(lactic-co-glycolic acid)-coated coil promotes intra-aneurysmal tissue healing. In this study, we demonstrate that interleukin-6 (IL-6) and osteopontin are downstream mediators in the MCP-1-mediated aneurysm-healing pathway. METHODS Murine carotid...

BACKGROUND AND PURPOSE Mechanisms underlying bleeding in nonaneurysmal perimesencephalic SAH remain unclear. Previous investigators have suggested a relationship between nonaneurysmal perimesencephalic SAH and primitive venous drainage of the basal vein of Rosenthal. We performed a meta-analysis to evaluate the relation between primitive basal vein of Rosenthal drainage and nonaneurysmal perime...

Pulmonary arteriovenous fistula is a congenital and rarely acquired anomalous direct communications between pulmonary arteries and veins. Transcatheter embolization using metallic coil or detachable balloon is one of the common treatment procedure. However, recanalization after the embolization is one of the concern and its differentiation from the retrograde filling via pulmonary vein is diffi...

Background: Aneurysmal hemorrhages have been the mostly seen cause of spontaneous subarachnoid hemorrhages. are situations with a high rate mortality and morbidity. It is really crucial that treatment an aneurysm should be operated by experienced tertiary clinics. Newly established clinics need doctors clinic reflexes in which patient follow-up conducted properly order to manage process ideally...

Background: The aim of this study was to assess geometrical modifications the aneurysmal Thoracic Aorta (TA) after Endovascular Repair (TEVAR) over 3 years follow-up, identify features predicting unfavorable evolution.

Introduction: Aneurysmal bone cyst is a rare, non-neoplastic lesion affecting the metaphysis of long bones and vertebrae, characterized by blood-filled spaces separated fibrous septae. Aims objectives: In this study, we present case an aneurysmal in 7-year-old child with characteristic X-ray findings to increase awareness as early diagnosis treatment can limit disability. An benign neoplastic s...
