How is drilled cranial hematoma puncture and drainage used to treat cerebral hemorrhage?

Hematoma puncture and drainage is currently one of the least invasive surgical methods for the treatment of hypertensive cerebral hemorrhage. During the operation, only a 4~5 cm incision is made on the scalp and a hole of about 1 cm in diameter is drilled in the skull, and a drainage tube with an outer diameter of 2~3 mm is selected to puncture the hematoma cavity, during which part of the liquefied hematoma can be extracted to achieve the purpose of decompression. Despite the simplicity of the operation, the procedure requires a high level of puncture technique, the key of which is to place the drainage tube in the right place in the deep cerebral hematoma cavity, which requires precise puncture technique. Currently, the commonly used puncture methods include stereotactic-guided puncture of the hematoma, neuronavigation-assisted puncture of the hematoma, real-time CT monitoring of the hematoma, and freehand puncture of the hematoma based on CT film positioning. Stereotactic orientation requires the installation of a positioning frame in the patient’s head, which is time-consuming and labor-intensive, and neuronavigation requires high scanning image requirements, and both methods require special instrumentation and equipment support, and preoperative CT scans of the head again, which are not suitable for emergency patients at night. puncture under CT real-time monitoring is even more difficult to carry out in general hospitals because it occupies public hospital resources. Therefore, most primary hospitals use CT slice positioning for freehand puncture, which is the simplest method, but still requires preoperative CT scanning again after applying markers to the patient’s head for positioning. In order to better adapt to the characteristics of emergency surgery, we designed a simple positioning puncture instrument (patented) based on the principle of stereotactic orientation, and perfected the transfrontal puncture technique (we call it simple transfrontal approach positioning puncture), using this technique, there is no need to re-CT positioning scan, which greatly shortens the preoperative preparation time, while the whole procedure can usually be completed in about half an hour.
