The replanted finger after a complete amputation is an excellent model for the study of many aspects of vascular physiology. In the present clinical study, 10 patients were investigated to evaluate the incidence of cold-induced vasospasm in replanted digits during the early postoperative period. The results indicate that cold-induced vasospasm is not a risk factor in the early postoperative phase after digital-replantation surgery. It is concluded that cold-induced spasm of the digital arteries is primarily a central, nerve-mediated reflex.
完全离断再植后的手指是研究血管生理学诸多方面的极佳模型。在本临床研究中，对10例患者进行了调查，以评估术后早期再植手指中冷诱导血管痉挛的发生率。结果表明，冷诱导血管痉挛不是断指再植术后早期的危险因素。得出的结论是，指动脉的冷诱导痉挛主要是一种中枢性、神经介导的反射。
