Abstract:
Objective To evaluate the significance of surgical exploration for the refractory arterial crisis daring the hypersensitive period (48 h to 96 h) after replantation of severed fingers.Methods One hundred and seventy-one patients experienced refractory arterial crisis during the hypersensitive period after replantation of the proximal thumb from February 1995 to February,2005 in our department.Eighty-seven of them were managed with surgical exploration,including incision injury (n=6),saw injury (n=17),rotation and avulsion injury (n=30), and crush injury (n=34).Eighty-four cases received conservative treatment,including incision injury (n=6),saw injury (n=16).rotation and avulsion injury (n=29),and crush injury (n=33).In the surgery group,the e- mergent explorations were performed as soon as the refractory arterial crisis arose,If arterial spasm or/and thrombosis were found,the involved parts were resected before the artery ends were anastomosed or the finger artery was repaired by cubital vein graft.In the other group,conservative managements were carried out by using intramuscular injection of 30 mg Papaverine and intravenous injection of 20,000-unit Urokinase in 20 mL normal saline.If symptums were not alleviated after half an hour,the procedures were repeated.The conservative managements also included abirritative antipsychotics and analgesia of anodyne.Meanwhile,the survival state of all the digital replants was observed. Results In the surgery group,78 fingers survived,the surviving rate being 89.7%.In the conservative group,41 fingers survived with a surviving rate of 48.8%.The difference was statistically significant (P＜0.01).No obvious complications happened in the two groups.Conclusion Since surgical exploration is crucial to management of refractory arterial crisis during the hypersensitive period after replantation of severed fingers,it should not be readily abandoned.
