The pedicled venous flap is used at various sites, such as the finger, forearm, and leg. The authors previously reported that the reasons for the viability of such flaps, based on the digital dorsal vein and used for repairing digital skin defects in the earlier study, were high venous pressure or oxygen tension, as well as the possible effects of plasmatic imbibition and outflow through the draining vein. To investigate the importance of venous pressure and oxygen tension in the survival of these flaps at other sites in the body, measurements were made comparing these parameters in the digital vein, cephalic vein, and greater saphenous vein, which are all used clinically as draining veins in pedicled venous flaps. Although measurements in other sites were consistently lower than in the digital dorsal vein, since these other venous flaps are nevertheless viable in the clinical situation, their viability may not be due only to relatively high venous pressure and oxygen tension. The authors intend to carry out further comparative studies on plasmatic imbibition in the flap and outflow through the draining vein.
带蒂静脉皮瓣可用于手指、前臂和腿部等不同部位。作者此前报道，在早期研究中基于指背静脉用于修复手指皮肤缺损的此类皮瓣存活的原因是静脉压或氧张力较高，以及血浆吸收和通过引流静脉流出的可能作用。为了研究静脉压和氧张力对这些皮瓣在身体其他部位存活的重要性，对指静脉、头静脉和大隐静脉（这些在临床上均用作带蒂静脉皮瓣的引流静脉）的这些参数进行了测量比较。尽管其他部位的测量值始终低于指背静脉，但由于这些其他静脉皮瓣在临床情况下仍然存活，其存活可能不仅仅归因于相对较高的静脉压和氧张力。作者打算对皮瓣中的血浆吸收和通过引流静脉的流出进行进一步的比较研究。
