SPLENORENALNY ANASTOMOSIS (Greek splen spleen + lat. ren kidney; Greek anastomosis the mouth, an exit) — operation of creation of an anastomosis between splenic and left renal veins.
For the first time in a wedge, the practician S. and. Bleykmor and the Lord imposed in 1945 (And. H. Blakemore, J. W. Lord).
So-called central (proximal) S.'s imposing is most of all widespread and. and anastomosis side sideways. Also the selection S. is applied and. without removal of a spleen.
Indication to operation the varicosity of a gullet at patients with cirrhosis serves in a stage of compensation. Abroad S. and. apply also in emergency situations at already developed bleeding from veins of a gullet. S.'s imposing and. contraindicated at a hepatic decompensation, especially at ascites, jaundice, low albuminoglobulinovy coefficient, etc.
Central S. and. usually impose in position of the patient on the right side with a deviation of a trunk back at an angle 45 — 60 °. The Abdominodiafragmalny or slanting section in left hypochondrium (see. Laparotomy ) open an abdominal cavity. After bandaging of a splenic artery and crossclamping of a splenic vein make splenectomy (see). Would will mobilize a stump of a splenic vein on an extent not less than cm and after a section of a fatty tissue along a vascular leg of a left kidney allocate her vein, in a wall a cut cut the oval opening corresponding to diameter of a splenic vein. Then the stump of a splenic vein is anastomosed with a renal vein (fig., a).
At S.'s performance and. a side sideways with preservation of a spleen it is possible to apply a median laparotomy. Bare a splenic vein, mobilizing bottom edge and a back surface of a pancreas. Then allocate the left renal vein throughout 6 — 7 cm. In walls of both veins cut oval openings 16 — 18 mm long and 6 — 7 mm wide then between them impose an anastomosis (fig., b).
The selection S. and. also it can be carried out by means of a median laparotomy. Impose an anastomosis a side sideways between renal and splenic veins, and then cross a splenic vein proksimalny an anastomosis after bandaging or underrunning by a stapler.
At S.'s imposing and. by Warren's method the splenic vein is crossed, the stump of the proximal end is tied up, and a distal stump anastomose with a renal vein the end sideways with preservation of a spleen (fig., c).
From postoperative complications thrombosis of an anastomosis is possible, the probability to-rogo increases during removal of a spleen. Later complication is development of encephalopathy. According to M. D. Patsior (1974), at the central S. and. symptoms of encephalopathy and a recurrence of bleeding from expanded veins of a gullet arose considerably more often than at the selection S. and.
