Evaluation for Vertebral Artery Injury with Cervical Dislocated Fracture and Optimal Treatment before Reduction.

Objective: Cervical dislocated fractures frequently cause vertebral artery injury (VAI), which, in turn, propagates the thrombus at the site of injury. Cerebral embolism due to a thrombus after the reduction of dislocation leads to a poorer neurological outcome. Therefore, we investigated the outcome of treatment for cervical dislocated fractures and the usefulness of parent artery occlusion (PAO) before reduction.

Efficacy of Monitoring for Multiple Antiplatelet Therapy during Intracranial Stent Placement: A Preliminary Study.

Objective: During cerebral aneurysm embolization using intracranial stents, platelet aggregation increases owing to increased wall shear stress and a loss of vascular endothelial function at the stent implantation site. Preoperative multiple antiplatelet therapy was introduced to prevent severe thromboembolic complications due to increased platelet aggregation. However, specific guidelines for the administration and pharmacological evaluation of this therapy do not exist currently.

Histological and Transmission Electron Microscopy Results after Embolization with HydroSoft/HydroFrame Coils in Experimental Swine Aneurysm.

Coiling and clipping are standard treatment strategies for cerebral aneurysms. Regardless of the strategy used, recanalization may affect the patient's prognosis. The aim of this study was to histologically and morphologically compare the tissue proliferation after coil embolization using bare platinum coils versus second-generation hydrogel coils (HydroSoft/HydroFrame; MicroVention, Inc.

Intracranial Aneurysm Model for Detachable Coil Testing.

Intracranial aneurysm is major vascular disease which is life-threatening and challenging treatment. Detachable coil is one of the standard treatments. Because of little knowledge about it, the detachable coils were evaluated by various methods.

[Case Report of Cerebellar Vermis Arteriovenous Malformation Presenting with Hydrocephalus due to Aqueductal Stenosis].

A 56-year-old man complained of gait disturbance and confused thinking. Magnetic resonance imaging(MRI)revealed an arteriovenous malformation(AVM)of the cerebellar vermis(Spetzler-Martin grade IV)causing hydrocephalus. One dilated precentral cerebellar vein was compressing the aqueduct.

Intercavernous sinus dural arteriovenous fistula treated with transvenous coil embolization: a case report.

The blood supply to the region of the cavernous sinus is provided by interconnecting branches of the internal and external carotid arteries, and it is from these vessels that dural arteriovenous fistulas (DAVFs) arise. It is very rare that DAVFs are located at the intercavernous sinuses region; in this case, a proper localization of the fistulous site is of extreme importance in order to successfully eliminate the disease. Here, we describe a case of a 65-year-old female with intercavernous sinus DAVF.

Radiological changes in infantile dissecting anterior communicating artery aneurysm treated endovascularly. A case report and five-year follow-up.

Intracranial aneurysms are extremely rare in infants, and to our knowledge only seven infants treated for ruptured spontaneous dissecting aneurysms have been reported. Good outcomes have been achieved with endovascular treatment of infantile aneurysm. We the endovascular treatment of a one-month-old girl for ruptured dissecting aneurysm located in the anterior communicating artery, and the unique radiological changes that were observed during the perioperative and follow-up periods.

Orbital cavernous hemangioma presenting with atypical appearance: case report.

A 25-year-old male presented with unilateral retroorbital dysesthesia persisting for 2 weeks followed by progressive palpebral ptosis without preceding trauma, paranasal sinus surgery, or infectious signs. Neuroophthalmological inspection revealed mildly increased intraocular pressure and exophthalmos on the affected side, without conjunctival chemosis, restriction of the extraocular movements, double vision, or visual impairment. These symptoms did not vary with posture, straining, and Valsalva maneuver.

Pleural malignant mesothelioma causing cord infiltration through the nerve root. Case report.

A 61-year-old man presented with a rare pleural malignant mesothelioma of the spine manifesting as progressive weakness of the bilateral lower extremities, numbness in the body and both legs, and dysfunction of the bladder and bowel. He had previous occupational exposure to asbestos while working at a car repair shop and had undergone right panpleuropneumonectomy under a diagnosis of sarcomatous type mesothelioma in the right pleural space. Magnetic resonance imaging of the spine with gadolinium showed an enhanced intramedullary tumor at the T4 level.

[Case with large abdominal abscess associated with a ventriculoperitoneal shunt].

Abdominal abscess is a rare shunt-related complication with few reported cases. A 6-year-old female presented with a large staphylococcal abdominal abscess manifesting as abdominal distension without significant clinical signs or blood and cerebrospinal fluid findings of infection. The patient had undergone repeated surgeries for craniopharyngioma at 2 years of age and had suffered central pontine and extrapontine myelinolysis during the clinical course, had severely impaired hypothalamic function, and was in a vegetative state on presentation.

[Huge falx meningioma resected en bloc following acute brain swelling: a case report].

Surgery of a meningioma is composed of four essential consecutive steps; devascularization, detachment, debulking, and dissection. However, this is not the case with a huge meningioma in which circumferential devascularization and detachment may be difficult to complete before debulking is attempted. We report a case of a 37-year-old female presented headache, memory disturbance, and character change and sustaining a huge falx meningioma, with hypervascular appearance.

Orbital dermoid cyst with intratumoral inflammatory hemorrhage: case report.

An 85-year-old female presented with a 3-month history of worsening hyperlacrimation and blurred vision following blunt head injury. Her past medical history was unremarkable. Her blood examination identified no abnormal findings.

Sporadic intra-abdominal desmoid with acute abdomen.

We report a 72-year-old man with sporadic intra-abdominal desmoid tumor manifesting as acute abdomen. CT scan revealed an air-containing tumor 7 cm in diameter; three weeks later, the tumor had shrunk to 4 cm on antibiotics. At surgery, a tumor arising from the transverse colon mesentery and infiltrating the jejunum was resected.
