Splenocaval shunting was performed in 26 patients for the treatment of
variceal bleeding. The indications for this alternative selective shunt
were congenital anomalies of the left renal vein, inadequate outflow from
the left renal vein on preoperative venography, or an anatomic relationship
of the splenic vein favoring direct splenocaval rather than splenorenal
anastomosis. Technical considerations in which splenocaval shunts differ
from distal splenorenal shunting relate to exposure of the vena cava.
Operative mortality was 7.7% (2/26). Immediate shunt patency was documented
in 23 of 24 patients studied, and all 14 shunts studied at 13 to 57 months
were patent. Portal perfusion was maintained in 95% (20/21) of the patients
when studied at 7 to 10 days after shunting and in 57% (8/14) at late
follow-up. This experience with distal splenocaval shunting has reaffirmed
its place as an alternative technique to selective distal splenorenal
shunts, particularly when the left renal vein is abnormal.
