Anterior cranial fossa dural arteriovenous fistula surgery

This part of AVF is extremely rare. Kobayashi collected the literature in 1988 and 2 of them, a total of 28 cases. The blood supply artery is mostly the anterior ethmoid artery, the middle meningeal artery and the ophthalmic artery. The drainage vein is often aneurysmal enlargement. Due to the more easily bleeding (22 of 28 cases), surgery is often required. Treatment of diseases: acute subdural hematoma Indication 1. A person with a history of bleeding or bleeding. 2. Patients with neurological dysfunction or neurological dysfunction are gradually aggravated. 3. Increased intracranial pressure due to venous return disorder, or cerebral angiography see drainage of the sinus has been occluded. 4. People with severe headaches or (and) intolerable vascular murmurs. Contraindications 1. No significant neurological dysfunction and history of bleeding. 2. Old and frail with other chronic diseases. Preoperative preparation The design of the incision during craniotomy is very important. It must be accurately positioned before surgery to design a surgical approach to meet the needs of surgical operations. Be prepared for blood. Surgical procedure 1. The forehead craniotomy. 2. Lift the frontal lobes outwards to reveal the anterior cranial fossa. Arteriovenous abnormal traffic is mostly located in the olfactory sulcus near the junction of the cerebral palsy and the anterior cranial fossa. The blood supply artery is not only from the branch of the dura mater artery, but also from the branch of the cerebral palsy. Drainage veins are mostly varicose veins, iliac veins and bridge veins. 3. Since the deformed vascular mass is mostly on the surface of the dura mater and is small, it can be removed together with the dura mater after exposure. The excised dura mater should be repaired to avoid cerebrospinal fluid leakage after surgery. The esophageal feeding artery can be carefully electrocoagulated, and then the dilated balloon can be destroyed by bipolar coagulation, and then the operation is terminated. complication The prevention and treatment of brain edema caused by poor venous return after operation should be strengthened. And pay attention to the occurrence of cerebrospinal fluid leakage.
