We report the results of a laser Doppler scan (PeriScan PIM III, Perimed AB, Järfälla, Sweden) showing an ominous reduction of left-hand vascularization upon manual occlusion of the ipsilateral ulnar artery (Fig. 1B) compared with the resting condition (Fig. 1A), after a percutaneous coronary intervention via an uncomplicated left radial access using a 6-French 25-cm long sheath (Terumo Medical Corporation, Plymouth, Massachusetts). These findings indicate right radial artery occlusion (RAO) that was confirmed with vascular Doppler scanning (Fig. 1C). Results of the contralateral hand are shown in the lower row as a control (Figs. 1D through 1F).
Despite being mostly asymptomatic, RAO is not a benign complication, and its diagnosis is frequently missed because it requires time-consuming diagnostic testing (1,2).
The laser Doppler scan is a novel promising noninvasive diagnostic technique that allows quick and easy diagnosis of RAO after catheterization in an operator-independent manner. It uses a low-power laser beam and generates color maps of blood perfusion (3). This technique has several advantages over traditional methods: 1) blood flow is measured over the whole hand, avoiding measurement bias due to site-to-site variability; 2) it is quicker than vascular Doppler, the current standard of reference; 3) it is very simple to perform; and 4) no direct contact with the skin is required, avoiding potential artifacts.
This study was partly supported by a grant from the Italian Ministry of Education, University and Research (MIUR): PON 01_02833 “Cardiotech.” Drs. De Rosa and Passafaro contributed equally to this work. The authors have reported that they have no relationships relevant to the contents of this paper to disclose.
