Utility of Repeat Cerebrovascular Imaging among Hospitalized Stroke Patients.

Background And Purpose: The purpose of this study is to evaluate the frequency and clinical utility of repeat cerebrovascular imaging with computed tomography angiography (CTA) of the head after contrast-enhanced magnetic resonance angiography (CE-MRA) of the head in acute stroke patients.

Materials And Methods: All stroke patients admitted to 2 academic medical centers from January 1, 2012 through December 31, 2014 were identified as part of prospective radiology database if they underwent CE-MRA of the head followed by subsequent CTA of the head within 7 days. Two vascular neurologists blinded to CTA results retrospectively reviewed medical records including documented indications for imaging studies and clinical changes in patients to determine necessity of CTA.

Microsurgical management of basilar artery apex aneurysms: a single surgeon's experience from Louisiana State University, Shreveport.

Objective: Basilar artery apex aneurysms continue to generate technical challenges and management controversy. Endovascular intervention is becoming the mainstay in the management of these formidable aneurysms, but it has limitations, especially with large/giant or wide neck basilar apex aneurysms. There is paucity of data in the available literature pertaining to the successful management of large/giant, wide neck, and calcified/thrombosed basilar apex aneurysms.

Microsurgical management of giant intracranial aneurysms: a single surgeon experience from Louisiana State University, Shreveport.

Background: Surgical management of giant aneurysms is challenging because of multiple factors: aneurysm size, wide neck, thrombosis, and calcification. The risk of ischemic complications is higher when compared with smaller aneurysms. We present our surgical experience of clipping these difficult aneurysms.
