Description
Technical field
The present invention relates to technical field of surgical instruments, more particularly to a kind of side door body part flow arrangement.
Background technology
There is Portal hypertension in end-age cirrhosis patient, esophageal varices lead to alimentary canal（Oesophagus,
Stomach）Massive haemorrhage is the major causes of death of patient.Sengstaken-Blakemore tube compression hemostasis is that traditional treatment gastroesophageal varices are bent
The compression hemostasis of tension fracture bleeding, but success rate of hemostasis is low, painful.In recent years, as Emergency Endoscopy clinic should
With going deep into for research, scope ligation adds low dose of curing agent again in the cirso- extension injection of tissue binder at stomach bottom
It is proved to that there is preferable haemostatic effect, but for the patient of massive hemorrhage of gastrointestinal tract, since amount of bleeding is too big, the visual field is unclear in short-term
It is interior to be difficult to find bleeding position accurately and stop blooding；No matter Sengstaken-Blakemore tube hemostasis by compression or gastroscope lower hemostasia are all without reducing portal vein
Pressure, it is impossible to which rupture haemorrhage easily occurs again in effective hemostasis.
Through jugular vein liver inside door vena systemica bypass（TIPS）This Toluidine blue O technology introduce it is clinical since, into
A kind of primary treatment currently to control portal hypertension bleeding and difficultly curing ascites selects, through jugular vein liver inside door vena systemica point
Stream art needs to be worked to determine that operating time and needing does a large amount of Preoperative Method according to patient body situation, need number into
As angiography machine（DSA it is carried out under), operating time is long, can not be operated by bed；Therefore alimentary canal is gone out greatly
The emergency case TIPS of blood is not applied to simultaneously, and currently still mainly traditional Sengstaken-Blakemore tube hemostasis by compression is taken for such patient
And gastroscope lower hemostasia scheme is met an urgent need, if life danger will likely occur in hemostasis failure, patient.
