Abstract:
ObjectiveTo assess revascularization and vessel anastomosis in digital replantations with DSA.MethodsTwelve cases of digital replantations underwent digital subtract angiography during 2 to 4 days after fingers reattachment. The vessel anastomosis,hemodynamics,stenosis and discontinuation were investigated.The unobstructed and smooth anastomosis was suggested as early stage survival of the reattached fingers,the spasm and stenosis of the reattached vessels were considered as mild vascular crisis,and the discontinuation of hemodynamics were indicated as severe vascular crisis.ResultsThe total 27 vessels were clearly displayed on DSA.Of these vessels,23 vessels were unobstructed and smooth,all digits were survived.Diagnosis coincidence of early stage survival was 100%(23/23). Two vessels were obstructed,which were testified having thrombus by operation research.The other 2 vessels were spasm,the digits were also survived ultimately by expectant treatment.All 4 abnormal vessel anatomosis were found by DSA.Conclusion DSA is important modality in assessing revascularization and blood circulation for digital replantations,guiding in dealing with the vascular crisis,and in predicting early stage survival of the reattached digits.
