Cold induced arterial vasospasm was studied in ten patients with single digit replantation, by measuring finger systolic pressure at different finger temperatures. Each patient was examined three times; within 2 weeks of surgery, after 1 year and after 3 years. The replantations were performed using long arterial and venous grafts. Cold-related vasospasm is established during the first year after trauma, and thereafter seems to be persistent. It is concluded that the subjective cold tolerance, which affects all patients after digital amputation regardless of whether replantation is performed or not, is partly due to vasospasm. It is less pronounced in patients without pathological vasospasm in the replanted digit. Cold intolerance is likely to decrease during the first 2 years after replantation, but not to disappear completely.
通过测量不同手指温度下的手指收缩压，对10名单指再植患者的冷诱导动脉血管痉挛进行了研究。每位患者接受三次检查，分别在术后2周内、1年后和3年后。再植手术采用长动脉和静脉移植物进行。创伤后第一年即出现与寒冷相关的血管痉挛，此后似乎持续存在。得出的结论是，主观耐寒性在手指离断后影响所有患者，无论是否进行再植，部分原因是血管痉挛。在再植手指无病理性血管痉挛的患者中，这种情况不太明显。耐寒性可能在再植后的头两年内降低，但不会完全消失。
