Neovascularization at the saphenofemoral junction is one of the principal causes of recurrent varicose veins after great saphenous vein surgery. Because angiogenic stimulation from the exposed endothelium of the great saphenous vein stump is considered an important trigger for this process, we hypothesized that complete resection of the stump with endothelial inversion might lessen grade 2 groin neovascularization and thereby decrease recurrence of thigh varicosities.
Two groups of consecutive patients with primary varicose veins of the great saphenous vein were studied. Group A was a historical control group of 70 limbs (48 patients) in which conventional flush ligation was performed at the level of the saphenofemoral junction. Group B was a prospectively studied clinical trial cohort of 65 limbs (45 patients), wherein the great saphenous vein stump was completely resected using a side-biting clamp to isolate the saphenofemoral junction, and the resulting common femoral vein venotomy was closed with a running inverting suture. Early postoperative follow-up was performed at 6 weeks. Clinical examinations and duplex ultrasound scans were performed after 2 years of follow-up. Grade 2 groin neovascularization was defined by the presence of >3 mm tortuous new refluxing veins, typically communicating with recurrent varicosities in the thigh.
After 2 years, recurrent varicose veins were present in the thighs of 13 of 65 limbs (20%) in group A and in 22 of 61 limbs (36%) of group B (P = .049). Grade 2 neovascularization was present at the saphenofemoral junction in six of 65 limbs (9%) of group A and in 12 of 61 limbs (20%) of group B (P = .127).
Complete resection of the great saphenous vein stump and inversion suturing of the common femoral vein venotomy, instead of simple flush ligation at the level of the saphenofemoral junction, do not appear to decrease grade 2 neovascularization and related thigh varicosity recurrence after great saphenous vein stripping for primary varicose veins.
隐股交界处的新生血管形成是大隐静脉手术后复发性静脉曲张的主要原因之一。由于大隐静脉残端暴露的内皮细胞产生的血管生成刺激被认为是这一过程的重要触发因素,我们推测完全切除残端并使内皮反转可能会减轻2级腹股沟新生血管形成,从而降低大腿静脉曲张的复发率。
对两组连续的原发性大隐静脉曲张患者进行研究。A组为历史对照组,共70条肢体(48例患者),在隐股交界处进行传统的高位结扎术。B组为前瞻性研究的临床试验队列,共65条肢体(45例患者),使用侧咬钳完全切除大隐静脉残端以分离隐股交界处,并用连续反转缝合关闭由此产生的股总静脉切开术。术后6周进行早期随访。随访2年后进行临床检查和双功超声扫描。2级腹股沟新生血管形成的定义为存在>3mm的迂曲新反流静脉,通常与大腿复发性静脉曲张相通。
2年后,A组65条肢体中有13条(20%)大腿出现复发性静脉曲张,B组61条肢体中有22条(36%)出现复发性静脉曲张(P = 0.049)。A组65条肢体中有6条(9%)在隐股交界处出现2级新生血管形成,B组61条肢体中有12条(20%)出现2级新生血管形成(P = 0.127)。
对于原发性静脉曲张行大隐静脉剥脱术后,完全切除大隐静脉残端并对股总静脉切开术进行反转缝合,而非在隐股交界处进行简单的高位结扎,似乎并不能减少2级新生血管形成及相关的大腿静脉曲张复发。
