Mechanical thrombolysis using coil in acute occlusion of fenestrate m1 segment.

A fenestrated middle cerebral artery (MCA) is a rare congenital anomaly, and is related to interference in the normal embryonic development of the MCA. Fenestrated MCA has been regarded to have no clinical significance other than a rare event of hemorrhage from associated aneurysm. However, the fenestration within the arterial trunk can be an obstacle against thrombus migration and may be associated with a major cerebral infarction.

Clinical and radiological features of patients with aplastic or twiglike middle cerebral arteries.

Background: An aplastic or twiglike middle cerebral artery (Ap/T-MCA) is an extremely rare congenital anomaly related to interference in the normal embryonic development of the MCA.

Objective: To evaluate the clinical and radiological features of patients with an Ap/T-MCA.

Methods: A total of 1749 conventional cerebral angiography procedures were performed in 1282 patients from January 2005 to July 2011 at Daegu Fatima Hospital.

Clinical and angiographic results after treatment with combined clipping and wrapping technique for intracranial aneurysm.

Objective: There have been numerous follow-up studies of patients who had ruptured or unruptured intracranial aneurysms treated by wrapping technique using various materials have been reported. Our objective was to ascertain whether our particular wrapping technique using the temporalis muscle provides protection from rebleeding and any aneurysm configuration changes in follow-up studies.

Methods: Clinical presentation, the location and shape of the aneurysm, outcomes at discharge and last follow-up, and any aneurysm configuration changes on last angiographic study were analyzed retrospectively in 21 patients.
