Ultra-Early Induction of General Anesthesia for Reducing Rebleeding Rates in Patients with Aneurysmal Subarachnoid Hemorrhage.

Objective: Rebleeding of aneurysmal subarachnoid hemorrhage (aSAH) is one of the significant risk factors for poor clinical outcome. The rebleeding risk is the highest during the acute phase with an approximate rebleeding rate of 9-17% within the first 24 h. Theoretically, general anesthesia can stabilize a patient's vital signs; however, its effectiveness as initial management for preventing post-aSAH rebleeding remains unclear.

[A Case of Bilateral Carotid Injury Caused by Vinyl Umbrella Penetration Successfully Treated with Endovascular Therapy].

Here, we have reported a case pertaining to a 59-year-old man with bilateral traumatic carotid artery injury caused by vinyl umbrella penetration who was successfully treated. The patient fell from the stairs while holding an umbrella, which penetrated his neck. On admission, the patient was in a comatose state and the umbrella had been removed.

A case of pediatric paraspinal arteriovenous fistula with multiple fistulas.

Paraspinal arteriovenous fistula (AVF) is a rare vascular malformation. This is the first described case of a pediatric paraspinal AVF along nonvertebral segmental nerve with multiple fistulas. An 8 months-old girl was found to have a continuous murmur on the back on chest auscultation.

Transvenous embolization for craniocervical junction epidural arteriovenous fistula with a pial feeder aneurysm.

Arteriovenous fistulas at the craniocervical junction are rare vascular malformations with frequent hemorrhagic presentations, which may have a concurrent pial feeder aneurysm. A 65-year-old man presented with subarachnoid hemorrhage and angiography showed an epidural arteriovenous fistula at the C-2 level with an anterior spinal feeder aneurysm without perimedullary venous drainage. Transarterial coil embolization of the ruptured aneurysm and partial Onyx embolization of the shunt led to thrombosis of the aneurysm.
