[Brain infarction and cerebral venous thrombosis in paroxysmal nocturnal hemoglobinuria: case report].

A 65-year-old woman with a six-year history of paroxysmal nocturnal hemoglobinuria (PNH) was admitted due to weakness in the right leg following a seven-day history of fever and upper respiratory infection. MRI revealed several high-intensity areas in bilateral frontal lobe cortices and the left cerebellum on diffusion-weighted imaging, and signal hypointensity along the course of the cortical vein in the left frontal lobe on T*-weighted imaging. We diagnosed cerebral venous thrombosis and brain infarction, and commenced heparin infusion.

Periprocedural Outcomes of Carotid Artery Stenting in Elderly Patients.

Background: Carotid artery stenting has emerged as an alternative to carotid endarterectomy especially in patients with high risk of carotid endarterectomy. Older age (≥80 years old) was recognized as one of the high risk factors of carotid endarterectomy. However, the association between older age and increased risk of adverse events for carotid artery stenting has been reported.

Complications and Predictors of Hypotension Requiring Vasopressor after Carotid Artery Stenting.

A significant controversy exists regarding the clinical impact of hemodynamic depression on major adverse events after carotid artery stenting (CAS). The purpose of this study was to evaluate the incidence, predictors, and clinical significance of hypotension after CAS. A total of 118 cases of carotid artery stenosis were treated with CAS.

Factors for Achieving Safe and Complete Treatment for Unruptured Saccular Aneurysm Smaller Than 10 mm by Simple Clipping or Simple Coil Embolization.

Objective: Reducing complications from unruptured aneurysms (UAs) treatment is important. We clarify the criteria for achieving safe and complete treatment for UAs ≤10 mm by clipping or coil embolization.

Methods: This study included 59 newly treated UAs in the past 2 years.

Progress in the treatment of unruptured aneurysms.

Recent technological progress has reduced the complication rate of unruptured aneurysm. We treated 128 unruptured aneurysms between April 2006 and March 2012. Seventy-six aneurysms (59 %) were clipped and 52 (41 %) were coil embolized.

Mucinous adenocarcinoma arising from supratentorial intramedullary neuroenteric cyst with broncho-pulmonary differentiation.

Neuroenteric cysts are benign intradural endoderm cysts lined by gastrointestinal (GI) or tracheobronchial epithelial cells. Their malignant transformation is extremely rare and only six cases have been reported. In these cases, tissue lineage of the cystic endoderm cells giving rise to carcinoma was not clearly identified either as respiratory or as GI type.

Relationship between preoperative magnetic resonance imaging and surgical findings: aneurysm wall thickness on high-resolution T1-weighted imaging and contact with surrounding tissue on steady-state free precession imaging.

This study evaluated the aneurysm wall thickness by high-resolution T1-weighted imaging and the contact between the aneurysm and surrounding tissue by steady-state free precession (SSFP) imaging. The surgical findings were prospectively compared with these preoperative magnetic resonance (MR) imaging findings in 35 consecutive patients with 37 unruptured cerebral aneurysms (UCAs). The aneurysm wall was not visible in 13 UCAs, but was visible in 23.

Trigonal cavernous malformation with intraventricular hemorrhage: a case report and literature review.

We reported a case of trigonal cavernous malformation (CM) with intraventricular hemorrhage. This 67-year-old woman experienced sudden onset of loss of consciousness and her Glasgow Coma Scale (GCS) was 5 points (E1V1M3) on admission. CT scan demonstrated intraventricular hemorrhage and acute hydrocephalus.

Rare variant of persistent primitive hypoglossal artery, arising from the external carotid artery.

A 63-year-old man presented with an extremely rare variant of persistent primitive hypoglossal artery (PHA), which was found incidentally during examination for a contralateral asymptomatic internal carotid artery (ICA) stenosis. This anastomotic vessel arose from the external carotid artery, not the ICA, and joined the vertebrobasilar artery through the hypoglossal canal. Persistent PHA is rare and the reported incidence is 0.

[Two cases of spontaneous intracranial hypotension with bilateral chronic subdural hematomas].

Spontaneous intracranial hypotension (SIH) is characterized by postural headaches without obvious cause and is occasionally related to chronic subdural hematomas (CSHs). Brain sag due to decrease in cerebrospinal fluid, and growing CSHs may occur secondary to a decrease in intracranial pressure. Therapy for this condition differs from that for mere traumatic CSHs and is controversial.

Treatment selection for ruptured aneurysm and outcomes: clipping or coil embolization.

The International Subarachnoid Aneurysm Trial has shown that coil embolization achieves a better outcome for aneurysms treatable by either clipping or coil embolization. However, many ruptured aneurysms are hardly treatable by either clipping or coil embolization. Selection of either clipping or coil embolization will affect the treatment outcome for ruptured aneurysms.

Effects and complications of stereotactic aspiration for spontaneous intracerebral hemorrhage.

Stereotactic aspiration of intracerebral hemorrhage (ICH) improves the general condition of patients, promotes improvement of consciousness, and decreases the incidence of pneumonia, but may induce rebleeding. The present study investigated the effects of stereotactic aspiration and factors that inhibit rebleeding in 70 consecutive patients who underwent stereotactic aspiration for ICH. Consciousness was significantly improved after surgery.

Percutaneous vertebroplasty under three-dimensional radiography guidance. Technical note.

An accurate, safe, and convenient method for performing percutaneous vertebroplasty (PVP) under three-dimensional (3D) radiography guidance has been developed. Six PVP procedures were performed in 5 elderly stroke patients complaining of back pain caused by compressive fracture which interfered with further rehabilitation. T(1)-weighted magnetic resonance imaging showed low intensity and T(2)-weighted imaging showed high intensity in the fractured vertebral body.
