Routine Completion Angiography For Infrainguinal Bypasses Using Prosthetic Conduit: No Effect On Postoperative Patency

Published:March 09, 2023DOI:



      Recent studies have demonstrated increased postoperative patency with the use of routine completion angiography for bypass using venous conduit. Compared to vein conduits however, prosthetic conduits are less plagued by technical issues such as unlysed valves or arteriovenous fistulae. The effect of routine completion angiography on bypass patency in prosthetic bypasses has yet to be compared to the more traditional selective use of completion imaging.


      A retrospective review of all infrainguinal bypass procedures using prosthetic conduit completed at a single hospital system from 2001 to 2018 was performed. Demographics, comorbidities, intraoperative reintervention rates and 30-day rates of graft thrombosis were analyzed. Statistical analysis included t-tests, chi square tests and cox regression.


      Four hundred and ninety-eight bypasses that were performed in 426 patients met inclusion criteria. Fifty-six (11.2%) bypasses were classified into the routine completion angiogram group compared to 442 (88.8%) into the no completion angiogram group. Patients who underwent routine completion angiograms had a rate of intraoperative reintervention of 21.4%. When comparing bypasses that underwent routine completion angiography versus no completion angiography, there were no significant differences in rates of reintervention (3.5% vs. 4.5%, P=0.74) or graft occlusion (3.5% vs. 4.7%, P=0.69) at 30-days postoperatively.


      Almost one-quarter of lower extremity bypasses using prosthetic conduit that undergo routine completion angiography undergo post-angiogram bypass revision, however this is not associated with an increased graft patency at 30-days postoperatively.
