Acute internal carotid artery occlusion due to dissection of the paraclinoid segment: Diagnostic usefulness of angiographic findings during stent retriever deployment.

Intracranial artery dissection is an uncommon but possible cause of ischemic stroke, and is usually diagnosed based on imaging findings such as mural hematoma and dissection flap. However, it is challenging to recognize the underlying dissection in cases of acute large vessel occlusion. In this report, we present a case of acute internal carotid artery occlusion, in which the underlying dissection of the paraclinoid segment was found during the thrombectomy procedure.

Crossing double stent retriever technique for refractory terminal internal carotid artery occlusion.

Mechanical thrombectomy is highly effective for the recovery of acute ischemic stroke with large vessel occlusion. However, refractory occlusions are still encountered despite the use of currently available devices. In this article, we present a case of refractory terminal internal carotid artery occlusion treated with the "crossing double stent retriever technique.

[A Case of Moyamoya Disease with Postoperative Cerebral Hyperperfusion Syndrome Followed by Cerebral Infarction due to Watershed Shift].

The concept of "watershed shift"(WS)has been proposed as a cause of the ischemic complications following a superficial temporal artery-middle cerebral artery(STA-MCA)bypass operation performed for the management of moyamoya disease. Previous reports have observed that only 1.2-5.

Pituitary ischemic apoplexy in a young woman using oral contraceptives: a case report.

Estrogen is suggested to be one of the plausible risk factors for pituitary hemorrhagic apoplexy through pituitary hyperemia. We experienced a 33-year-old woman with pituitary ischemic apoplexy of a nonfunctional macroadenoma under oral contraceptive use. Our case indicates that hypercoagulable state, but not hyperemia, associated with estrogen may promote pituitary ischemic apoplexy.

[Is hyperdynamic therapy possible for elderly patients with vasospasm following subarachnoid hemorrhage?].

Background: Recently we have an increased number of elderly patients with subarachnoid hemorrhage (SAH) to be treated. Elderly patients are expected to have a worse cardiac function than that of younger patients. A question arises whether management for elderly patients in the vasospasm period can be performed as safely as it is for younger patients.

Concept of ideal closure line for clipping of middle cerebral artery aneurysms--technical note.

The concept of optimum closure line was applied to a series of 51 consecutive middle cerebral artery aneurysms (14 ruptured, 37 unruptured) in 41 patients, 16 men and 25 women aged 29-79 years (mean 59.1 years). Visual inspection through the operating microscope revealed 3 types of aneurysm based on the origin of the aneurysm: bifurcation type (n = 39), trunk type (n = 9), and combined type (n = 3).

[Elderly patient with cerebellar malignant astrocytoma].

Malignant cerebellar astrocytoma is very rare and the prognosis is extremely poor. We report herein the case of an elderly patient with malignant cerebellar astrocytoma. This 80-year-old man initially presented with dizziness and ataxia of the right hand.

Snoring associated with Ondine's curse in a patient with brainstem glioma.

Unlabelled: Ondine's curse is an uncommon type of sleep apnea syndrome characterized by failure of automatic respiration. We present an adult patient with brainstem glioma who presented with snoring and Ondine's curse as the only symptoms.

Case Report: A 52-year-old female was brought to the hospital by a fellow resident due to exceptionally loud snoring.

Acquired lumbar epidermoid cyst in an adult.

A 61-year-old female complained of low back pain, and had been treated by spinal anesthetic injection more than 70 times over 14 years. Magnetic resonance (MR) imaging, performed at the age of 47 years, revealed no abnormal lesion. However, she developed irritable hypesthetic pain in the left leg at 61 years of age.
