In this study post-mortem angiograms were prepared from both normal and clubbed hands and attempts were made to estimate the size of the vascular bed in the terminal parts of each finger. Representative cases were also examined histologically. There were no differences between the groups. The increase in blood flow in clubbing is the result of vasodilatation rather than hyperplasia of vessels in the nail bed.
在本研究中，制备了正常手和杵状指的死后血管造影照片，并试图估计每个手指末端血管床的大小。还对代表性病例进行了组织学检查。两组之间没有差异。杵状指中血流量的增加是血管舒张的结果，而非甲床血管增生所致。
