Cyanoacrylate glue is injected for incompetent great saphenous vein (GSV) treatment 5 cm distal to the saphenofemoral junction (SFJ). Although a few reports have investigated the postprocedural remnant stump length, none have focused on the factors affecting glue extension length and the consequent remnant stump length.
Seventy-nine patients undergoing cyanoacrylate closure using the VenaSeal system at our clinic between August 2018 and November 2018 were investigated. The GSV diameter was measured just before treatment in the supine position 3 cm distal to the SFJ. Cyanoacrylate glue was injected 5 cm distal to the SFJ.
The mean glue extension length was 1.13 ± 1.12 cm. The GSV diameter and glue extension length exhibited a significant inversely proportional relationship ( < .001). More specifically, patients with a GSV diameter ≥0.7 cm had a longer remnant stump length than those with a smaller GSV diameter ( < .001).
An increased GSV diameter is likely associated with a decreased glue extension length and, consequently, a longer remnant stump.
在隐股静脉交界处（SFJ）远端5 cm处注射氰基丙烯酸酯胶水以治疗大隐静脉（GSV）功能不全。尽管有一些报告研究了术后残余残端长度，但没有一项研究关注影响胶水延伸长度及随之产生的残余残端长度的因素。
对2018年8月至2018年11月期间在我们诊所接受使用VenaSeal系统进行氰基丙烯酸酯封堵术的79例患者进行了研究。在仰卧位治疗前，于SFJ远端3 cm处测量GSV直径。在SFJ远端5 cm处注射氰基丙烯酸酯胶水。
胶水平均延伸长度为1.13±1.12 cm。GSV直径与胶水延伸长度呈显著负相关（P<0.001）。更具体地说，GSV直径≥0.7 cm的患者残余残端长度比GSV直径较小的患者更长（P<0.001）。
GSV直径增加可能与胶水延伸长度减少相关，进而导致残余残端更长。
