Background Patients with polycystic kidney disease have a higher prevalence of intracranial aneurysms and may progress to renal failure requiring transplantation. The endovascular treatment of intracranial aneurysms may improve prognosis, since rupture often causes premature death or disability, but the nephrotoxicity risk associated with contrast medium must be always considered in cases of renal impairment. Methods A 55-year-old female patient with polycystic kidney disease and grafted kidney associated with anterior communicant artery aneurysm was successfully treated by embolization...

Background: Both hypertensive and atherosclerotic processes contribute to common carotid artery intima-media thickness (CCA-IMT). Elevated CCA-IMT may be indicative of subclinical cerebrovascular disease; however, its role in the absence of concomitant carotid artery plaque is uncertain, and few studies have examined associations in black populations. Materials and Methods: At cohort visit 3 (1993-1995) a subset of stroke-free participants (641 blacks and 702 whites, mean age 63) from the Atherosclerosis Risk in Communities (ARIC) study was imaged by brain MRI and carotid ultrasound...

BACKGROUND: Minimally invasive approach to distal anterior cerebral artery (DACA) aneurysms could not gain much acceptance due to the difficulties associated with conventional frontal paramedian approach. The more proximal basal interhemispheric approach however necessitated extensive dissection of soft tissues. We describe a minimally invasive median supraorbital keyhole craniotomy with basal interhemispheric approach for clipping a ruptured DACA aneurysm. METHODS: A 62-year-old patient presented with subarachnoid hemorrhage...

Microsurgical treatment of suprasellar tumors, in particular tuberculum sellae meningiomas, poses significant challenge. These tumors are surrounded by vital neurovascular structures, such as optic apparatus, pituitary stalk, internal carotid artery and its branches, and anterior cerebral arteries. In large and complex cases, early identification and decompression of these structures may facilitate safer dissection and resection. Therefore, extradural anterior clinoidectomy with optic unroofing facilitates the internal carotid artery exposure and optic nerve decompression...
