An Ap/T-MCA is a rare anomaly and should be differentiated from moyamoya conditions and degenerative steno-occlusive diseases of the middle cerebral artery. Coexisting anomalies of the anterior or middle cerebral arteries are frequent. This anomaly is vulnerable to both hemorrhagic and ischemic strokes.
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. Moreover, the presence of this anomaly can be hardly detected prior to thrombolytic procedures, and emergent treatments are proceeded without any information of anatomical configurations. Therefore, the recanalization procedures would carry a high risk of intraprocedural complications. We report a rare case of MCA territory infarction from occlusion of fenestrated M1 segment, and also introduce a safe method of mechanical thrombolysis using coil.
Objective:The purpose of this study is to evaluate several technical factors of treatment that seemed to influence the recurrence of chronic subdural hematoma (CSDH). Methods: 140 patients with surgically treated CSDH between January 2004 and June 2009 were retrospectively reviewed. Patient's age and sex, the location of the burr-hole, the location and the length of the subdural catheter tip, and the amount of the postoperative subdural air accumulation were analyzed in relation with the recurrence rate. Results: This study revealed that the location of burr-hole trephination and the presence of postoperative subdural air accumulation had statistical significance in association with the recurrence whereas the location and the length of subdural catheter tip did not have statistical significance. Conclusion: We believe the greatest possible care to reduce chance of subdural air accumulation is required for preventing the recurrence of CSDH.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
