To determine the effect of increasing inferior vena cava blood flow by means of distal arteriovenous fistula on the patency of a peritoneal tube graft.
In 16 mongrel dogs, 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 arteriovenous fistula was also constructed in 8 dogs just after the caval interposition. Graft patency was evaluated by Doppler ultrasonography and angiography. Histological evaluation was also performed.
Seven dogs in each group survived. All control grafts occluded within the first week, compared to no occlusions in fistula group (Fisher's exact test, p<0.005). However one 'fistula' dog with a still patent graft was sacrificed on the 18th day due to ultrasonographically occluded arteriovenous fistula.
In dogs, the peritoneum may be used as graft material for reconstruction of the inferior vena cava, provided a distal arteriovenous fistula is constructed.
通过远端动静脉瘘增加下腔静脉血流量，以确定其对腹膜管移植物通畅性的影响。
在16只杂种犬的肾下下腔静脉处制造一个3 - 4厘米长的圆形缺损。用腹膜管移植物修补该缺损。8只犬在腔静脉修补术后即刻还构建了一个临时的远端股-股动静脉瘘。通过多普勒超声和血管造影评估移植物的通畅性。还进行了组织学评估。
每组有7只犬存活。所有对照移植物在第一周内均发生堵塞，而瘘管组无堵塞情况（Fisher精确检验，p<0.005）。然而，有一只移植物仍保持通畅的“瘘管”犬，因超声检查显示动静脉瘘堵塞，在第18天被处死。
在犬类中，如果构建远端动静脉瘘，腹膜可作为下腔静脉重建的移植物材料。
