Rapid Pore Drilling Cranial Treatment of Intraventricular Hemorrhage in 42 Cases: The ventricular needle is inserted along the borehole channel into the ventricle, removing the core needle upon seeing cerebrospinal fluid outflow. The ventricular short tube drainage is conducted in vitro by directly inserting and exiting the trocar, using a short silicone tube equipped with a wire core to directly enter the ventricle. Early in the drilling process, the borehole is sutured with a needle, scalp covered partially with gauze, marking the end of surgery. CT scan results show that the intraventricular hematoma is basically clean, the aqueduct and fourth ventricle are displayed smoothly. Efficacy revised according to the 1986 cerebrovascular disease classification...: 17 cases cured, accounting for 40%; significant progress in 12 cases, accounting for 28%; progress in eight cases, accounting for 19%; three cases, accounting for 7%; two patients died, accounting for 4%. Discussion on hypertensive intracerebral hemorrhage ruptured into the ventricle refers to brain hemorrhage breaking into the ventricular system. Conventional treatment for small amounts of bleeding shows symptoms disappearing slowly, relatively longer hospital stays, general bleeding absorption takes three weeks. The mortality rate of severe intraventricular hemorrhage under conservative treatment can reach up to 60%-90%. Blood clots breaking into the ventricle, third ventricle, cerebral aqueduct, and fourth ventricle often cause acute obstructive hydrocephalus, resulting in sharply increased intracranial pressure, high blood pressure, further deterioration, and soon cerebral edema. Parts of the original blood clot, still through the destruction of the brain wall, are constantly washed into the intraventricular flow injection into the subarachnoid space, with a large number of bloody cerebrospinal fluid inflow directly stimulating blood cells to destroy the release of 5-HT, which can cause cerebral vasospasm. Therefore, rapid removal of intraventricular hemorrhage and reduction of intracranial pressure are key to rescuing intraventricular hemorrhage. Ventricular drainage infusion of urokinase allows intraventricular blood clots to dissolve as soon as possible, ensuring the patency of the drainage tube, clearing intraventricular hemorrhage as soon as possible, lifting factors obstructing cerebrospinal fluid circulation to rapidly reduce intracranial pressure, reducing stimulation of the hypothalamus and brain stem, reducing cerebral vasospasm, preventing irreversible damage to brain parenchyma. Bloody cerebrospinal fluid and dissolved hematoma drainage reduce arachnoid adhesions, decreasing the incidence of hydrocephalus, establishing cerebrospinal fluid recycling as much as possible, reducing hematoma disability. Simple operation, easy to master, can be completed at the bedside, saving time and discomfort to patients, safe and reliable, yielding satisfactory results.
