Description
Technical Field
The invention relates to the technical field of ventricular shunt, in particular to a ventricular shunt system.
Background
Isolated temporal corner synthesis is a common complication after neurosurgical intracerebral tumor surgery, and the isolated and enlarged temporal corner caused by the hydrops causes the disability and even death of patients, so the treatment is very difficult. The current treatment method principle is to drain the temporocele hydrops into absorbable areas (such as the abdominal cavity, the anterior pontine and the lateral ventricles), including ventricles and abdominal shunt, endoscopic choroid fissure fistulization and shunt, with poor effect and many complications.
The ventricular peritoneal shunt drains the cerebrospinal fluid in the temporal angle to the peritoneal cavity for absorption, and has the defects of long pipeline path, disruption of physiological circulation of the cerebrospinal fluid, frequent blockage and infection of a shunt tube, long-term occurrence of shunt tube dependent headache and abdominal complications, need of secondary operation for adjusting the shunt tube, high cost and increased pain of a patient. The endoscopic choroid fissure ostomy drains cerebrospinal fluid in the temporal angle to a front bridge pool through the medial choroid fissure ostomy of the temporal angle, has high technical requirements on operators, has a complex anatomical structure, is easy to cause complications such as brainstem and vascular injury, has a certain failure rate, needs to be operated again, and is difficult to popularize. In the transdrainage, cerebrospinal fluid in the temporal corner is bypassed and drained to the frontal corner where the cerebrospinal fluid normally circulates through a communicating pipe, and compared with ventriculoperitoneal shunt, the transdrainage has the advantages of short pipeline path, difficulty in blockage and infection, no abdominal complications, short operation time and low cost; compared with endoscopic venation fissure fistulation, the technology is simple and easy to popularize. However, the traditional transfusions are rarely used because of the defects in the ventricular-temporal corner puncture site and access: the temporal angle puncture point is positioned on the temporal bone and passes through the temporal lobe cortex, so that epilepsy complications are easy to occur; the path is close to the lateral fissure and transversely punctures and faces to the brainstem, so that the injuries of the lateral fissure vein, the middle artery and the brainstem are easily caused; the transverse diameter of the temporal angle is short, so that the ventricular end with enough length cannot be ensured to be positioned in the temporal angle, and the ventricular end is easy to separate along with the reduction of the temporal angle, thereby influencing the treatment effect; the position of the tube end is close to the choroid plexus, the side hole of the tube end is easy to be wrapped and blocked by the temporal choroid plexus, and the drainage tube needs to be adjusted by operation again.
