Isolated temporal angle synthesis is a common complication after neurosurgery brain indoor tumor operation, and the treatment is very difficult because the isolated expansion of the temporal angle caused by ponding causes disability and even death of patients. The current treatment principle is to drain the temporo-hydraulic fluid into absorbable areas (such as abdominal cavity, anterior bridge pool and lateral ventricle), including ventricular and abdominal shunt, endoscopic venation split fistulization and diversion, with poor effect and many complications.
The cerebral ventricle-abdominal shunt operation is used for draining cerebrospinal fluid in the temporal angle to the peritoneal cavity for absorption, and has the defects of long pipeline path, breaking of cerebrospinal fluid physiological circulation, shunt tube blockage and infection frequently occur, shunt tube dependent headache and abdominal complications occur in a long term, shunt tubes need to be adjusted again in an operation, and the cost is high and the pain of patients is increased. Endoscopic choroidal split fistulization is through the inside choroidal split fistulization drainage temporo-horn cerebrospinal fluid of temporo-horn to the front axle pond, and is very high to the technical requirement of art person, and anatomy structure is complicated, easily appears complication such as brain stem and vascular injury, has certain failure rate, need the operation once more, is difficult to popularize. The diversion technique leads cerebrospinal fluid in the temporal angle to the frontal angle of the normal circulation of the cerebrospinal fluid through a communicating pipe bypass, and compared with the ventricular and abdominal shunt technique, the diversion technique has the advantages of short pipeline path, difficult blockage and infection, no abdominal complications, short operation time and low cost; compared with endoscopic venation, the method has the advantages of simple technology and easy popularization. However, conventional current transfer has few applications because of defects in ventricular temporal puncture points and access: the puncture point of the temporal angle is positioned on the temporal bone, and the temporal lobe cortex is subjected to the meridian, so that epileptic complications are easy to occur; the path is near to the side fissure, is transversely punctured and faces to the brainstem, and is easy to cause damage to the side fissure vein, middle artery and brainstem; the transverse diameter of the temporal angle is short, so that the ventricle end with enough length can not be ensured to be positioned in the temporal angle, and the ventricle end is easy to deviate along with the shrinkage of the temporal angle, thereby affecting the treatment effect; the tube end is close to the choroid plexus, the tube end side hole is easily wrapped and blocked by the temporal choroid plexus, and the drainage tube is required to be adjusted by a secondary operation.
