Reconstruction of the vena cava with the peritoneum: the effect of temporary distal XXXX on patency (an experimental study).

@entity235 @entity2548 @entity292
OBJECTIVE: To determine the effect of increasing inferior vena cava blood flow by means of distal @entity2548 on the patency of a peritoneal tube graft. MATERIALS AND METHODS: In 16 mongrel @entity235 , a 3-4 cm long circular defect was created at the infrarenal inferior vena cava. The defect was interposed with peritoneal tube graft. A temporary distal femoro-femoral @entity2548 was also constructed in 8 @entity235 just after the caval interposition. Graft patency was evaluated by Doppler ultrasonography and angiography. Histological evaluation was also performed. RESULTS: Seven @entity235 in each group survived. All control grafts occluded within the first week, compared to no occlusions in @entity292 group (Fisher's exact test, p<0.005). However one ' @entity292 ' @entity235 with a still patent graft was sacrificed on the 18th day due to ultrasonographically occluded @entity2548 . CONCLUSION: In @entity235 , the peritoneum may be used as graft material for reconstruction of the inferior vena cava, provided a distal @entity2548 is constructed.
