There are two approaches to the treatment of brain hemorrhage, namely surgical and non-surgical treatment. Which patients need surgical treatment? ① Those with hemorrhage in the cerebral hemisphere of more than 30ml. (ii) Those with cerebellar hemisphere hemorrhage greater than 10ml. (3) Those with ventricular hemorrhage causing hydrocephalus. The rest of the patients can be treated non-surgically, i.e. medically. What are the methods of surgical treatment for cerebral hemorrhage? The current surgical methods of neurosurgery for cerebral hemorrhage are divided into the following: First: placement of a tube for hematoma drainage. By drilling a hole in the head and placing a drainage tube into the hematoma in the brain, continuous drainage is performed. If the flow of the hematoma is low, blood clots can be melted and then drained out by injecting blood-clotting drugs into the hematoma through the drainage tube. Indications: ①Patients with hemorrhage in the cerebral hemisphere without brain herniation, with a hematoma volume of approximately 30-60 ml. ②The technical level of the surgeon placing the tube is required to be high. The second type: intracerebral hematoma removal with a small bone window. The method is to take a small incision in the head, drill a hole in the skull, bite the bone to enlarge the bone hole diameter up to 3-5 cm, and enter the brain through the bone hole to remove the hematoma. Indications for surgery: patients with hemorrhage in the cerebral hemisphere without brain herniation, with hematoma volume between 30-60 ml; hemorrhage in the cerebellar hemisphere greater than 10 ml. The third type: bone flap craniotomy for intracerebral hematoma removal. The method is to lift up the bone flap and remove the intracerebral hematoma, and then the bone flap is covered up again. Indications for surgery: patients with hemorrhage in the cerebral hemisphere with a large hematoma volume of more than 50 ml, but without brain herniation. Type IV: hematoma removal and external decompression. After removal of the hematoma, the scalp is sutured and the bone flap is removed. Indications for surgery: Patients with cerebral hemispheric hemorrhage who have undergone brain herniation. Why is it necessary to remove the bone flap? Because patients with brain herniation often have a large amount of bleeding and brain damage, and postoperative cerebral edema is obvious, so if the bone flap is pressed back, brain herniation (a critical condition that endangers the above) cannot be relieved and can still be life-threatening, so the bone flap must be removed. The fifth type; cone cranial placement ventricular hematoma external drainage. A hole is made in the head cone and a drainage tube of about 2-4 mm in diameter is placed into the ventricle to continuously drain the hematoma and cerebrospinal fluid. Indications for surgery: ventricular hemorrhage causing hydrocephalus. Different surgical methods are suitable for different patients, and each has its own advantages and disadvantages.
