Spontaneous chronic subdural hematomas in human immunodeficiency virus-infected patients with normal platelet count and no appreciable brain atrophy: Two case reports and review of literature
Date of publication: 03-Jun-2016
Background:Chronic subdural hematomas (CSDHs) usually occur in elderly patients following minor head trauma. Their occurrence is usually linked to cerebral atrophy secondary to alcohol, old age, or human immunodeficiency virus (HIV) infection. Spontaneous CSDHs have also been documented but are rare. They are usually caused by coagulopathies and various pathologies resulting in intracranial hypotension.
The use of fibrin and gelatin fixation to repair a kinked internal carotid artery in carotid endarterectomy
Date of publication: 03-Jun-2016
Background:The kinking of the internal carotid artery (ICA) after final closure in carotid endarterectomy (CEA) is thought to be uncommon. When it occurs, it is mandatory to reconstruct ICA to preserve normal blood flow. We herein present a case in which a fixation technique was applied to repair an ICA that became kinked during CEA.
A refractory arachnoid cyst presenting with tremor, expressive dysphasia, and cognitive decline
Date of publication: 03-Jun-2016
Background:Arachnoid cysts are common incidental findings on intracranial imaging, although they are rarely symptomatic.
Safe and accurate sylvian dissection with the use of indocyanine green videoangiography
Date of publication: 03-Jun-2016
Background:Sylvian dissection is an essential microneurosurgical skill for neurosurgeons. The safe and accurate opening of the sylvian fissure is desirable for a good prognosis.
Successful outcome after endovascular thrombolysis for acute ischemic stroke with basis on perfusion-diffusion mismatch after 24 h of symptoms onset
Date of publication: 03-Jun-2016
Background:Although intravenous thrombolysis is the Food and Drug Administration-approved treatment for acute ischemic stroke (AIS) within 3 h, combined intravenous and intra-arterial thrombolysis with endovascular techniques may be able to extend this traditional time window.
Sacrificing the superior petrosal vein during microvascular decompression. Is it safe? Learning the hard way. Case report and review of literature
Date of publication: 03-Jun-2016
Background:Venous infarction as a complication of microvascular decompression (MVD) is a recognized but extremely rare occurrence in an otherwise standard neurosurgical procedure. Sacrificing one or more veins is considered safe by majority of experienced surgeons and authors. However, in the recent years, there has been growing debate about the management of venous trigeminal compression and/or superior petrosal complex (separation vs. coagulation and cutting of the vein), with few papers describing mild to severe complications related to venous sacrifice.
Onyx removal after embolization of a superior sagittal sinus dural arteriovenous fistula involving scalp artery
Date of publication: 03-Jun-2016
Background:Most dural arteriovenous fistula (DAVF) in superior sagittal sinus (SSS) requires multimodal treatment. Onyx embolization is useful for DAVF; however, scalp artery embolization has cast extrusion risk.
Surgical flow modification of the anterior cerebral artery-anterior communicating artery complex in the management of giant aneurysms of internal carotid artery bifurcation: An alternative for a difficult clip reconstruction
Date of publication: 03-Jun-2016
Background:Internal carotid artery bifurcation (ICAb) aneurysms account for about 2–15% of all intracranial aneurysms. In giant and complex cases, treatment may be difficult and dangerous, once some aneurysms have wide neck and anterior cerebral artery (ACA) and middle cerebral artery (MCA) may arise from the aneurysm itself. Clip reconstruction may be difficult in such cases. Whenever possible, the occlusion of ACA transform the bifurcation in a single artery reconstruction (ICA to MCA), much easier than a bifurcation reconstruction.
An unusual variant of the callosomarginal artery from the A1 segment of the anterior cerebral artery
Date of publication: 03-Jun-2016
Background:Although the anatomy of the A1 segment of the anterior cerebral artery (ACA) is highly variable, a callosomarginal artery (CMA) arising from the A1 segment of the ACA is rare.
A unique case of calvarial hemangioma
Date of publication: 03-Jun-2016
Background:Calvarial hemangiomas are one of the rarest neoplasms affecting the skull, predominantly occurring in parietal and frontal bones.
