Infraoptic anterior cerebral artery (ACA) is an extremely rare congenital anomaly. This anomalous usually arises from the intradural internal carotid (ICA) near level of ophthalmic (OA) or rarely extradural ICA. anomaly frequently harbors a aneurysm, and may involve other coexisting vascular anomalies. In case this anomaly, surgical treatment aneurysm at proximal ACA communicating (ACoA) sometimes be difficult, because veiled by optic nerve would make control inconvenient vertical midline...

Pterional craniotomy (PC) using myocutaneous (MC) flap is a simple and efficient technique; however, due to subsequent inferior displacement (ID) of the temporalis muscle, it can cause postoperative deformities muscle such as depression along margin temporal line frontal bone (DTL) muscular protrusion at portion fossa (PITF). Herein, we introduce method for reconstruction contourable strut plate (CSP) evaluate its efficacy.Patients follow-ups between January 2014 October after PCs were...

Objective: Patients with traumatic acute subdural hematoma (ASDH) often require surgical treatment.Among patients who primarily underwent craniotomy for the removal of hematoma, some consequently developed aggressive intracranial hypertension and brain edema, required secondary decompressive craniectomy (DC).To avoid reoperation, we investigated factors which predict requirement DC by comparing groups ASDH did not after craniotomy.Methods: The 129 from September 2007 to 2017 were...

Spontaneous anterior cerebral artery (ACA) dissection, although extremely rare, is often associated with severe morbidity and mortality. It could lead to hemorrhage, ischemic stroke, or, rarely, combination of hemorrhage ischemia due hemodynamic changes. Prompt accurate diagnosis essential for determining the appropriate management. However, optimal treatment ACA dissection remains controversial. Herein, we report on two rare cases subarachnoid (SAH) caused by dissection; a case presenting...

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

Dural arteriovenous fistula (D-AVF) at the foramen magnum is an extremely rare disease entity. It produces venous hypertension, and can lead to progressive cervical myelopathy thereafter. On other hand, hypertension may formation of a varix, it rarely result in abrupt onset subarachnoid hemorrhage (SAH) when varix ruptured. The diagnosis D-AVF as cause SAH be difficult due its low incidence. Furthermore, fed solely by ascending pharyngeal artery (APA), missed if external carotid angiography...
