Abstract

Incompetent perforating vein (IPV) is often the cause of varicose veins with skin lesions and recurrent varicose veins. There are various treatments for IPV. We studied percutaneous ablation of perforators (PAPS) using the technique of endovenous laser ablation. The effectiveness of PAPS was measured by ultrasonography to determine the presence of IPV diameter change and reflux, and the symptoms were studied using venous clinical severity score (VCSS). The value of VCSS improved in all cases. All IPV backflow stopped. The IPV diameter is an average of 5.83 ± 1.13 mm preoperatively, 3.43 ± 0.40 mm (p = 0.01) one month after PAPS, and 2.90 ± 0.88 mm (p = 0.03) three months after PAPS (using t test). All IPV diameters were significantly reduced. PAPS has made it possible to provide treatment with simple procedures by device innovation. It is useful as a treatment for varicose veins showing various conditions.

静脉内激光消融治疗不功能穿孔静脉的临床效果
穿孔静脉功能不全是引起静脉曲张伴皮损和复发性静脉曲张的常见原因。IPV有多种治疗方法。我们研究了静脉内激光消融技术对穿支的经皮消融。通过超声检测PAPS的有效性,判断是否存在IPV内径改变和反流,并采用静脉临床严重程度评分(VCSS)对症状进行研究。VCSS值在所有情况下均有所提高。所有IPV回流停止。IPV直径术前平均为5.83±1.13 mm,术后1个月平均为3.43±0.40 mm (p = 0.01),术后3个月平均为2.90±0.88 mm (p = 0.03)(采用t检验)。所有内径均显著减小。PAPS通过设备创新使提供简单程序的治疗成为可能。它是一种有用的治疗静脉曲张显示各种条件。
