In free transfers of groin flaps in neurotized rats, spasms of the pedicle and of the vessels of the flap itself were observed. These spasms were in many cases the cause of complications. Four kinds of spasms were distinguished: 1. Segmental spasm--practically always on the inferior epigastric artery, characterized by short sections of spasm of the artery, alternating with sections of normal dilatation. 2. Spasm of the whole artery. 3. Spasm in the flap itself--characterized by normal dilatation of the artery stem of the flap and by slowing or stopping of blood circulation through the flap. 4. Tissue shock of the flap characterized by spasm of the pedicle in the flap also. The present work further shows a method of assessing the amount of blood circulation through the flap and the results of local medication influencing spasm, including 1% Mesocain, 0.5% Marcain and Solutio Vischnjevskij.
在神经化大鼠腹股沟皮瓣的游离移植中，观察到蒂部以及皮瓣自身血管的痉挛。这些痉挛在许多情况下是并发症的原因。区分出四种痉挛：1. 节段性痉挛——几乎总是发生在腹壁下动脉，其特征为动脉的短段痉挛与正常扩张段交替出现。2. 整个动脉的痉挛。3. 皮瓣自身的痉挛——其特征为皮瓣动脉干正常扩张，以及通过皮瓣的血液循环减慢或停止。4. 皮瓣的组织休克，其特征还包括皮瓣内蒂部的痉挛。本研究进一步展示了一种评估通过皮瓣的血液循环量以及局部用药对痉挛影响结果的方法，这些药物包括1%的美索卡因、0.5%的布比卡因和维斯涅夫斯基溶液。
