Venous leg ulcers (VLU) generally have slow healing rates (HR) and frequent recurrence rates (RR). The underlying etiology is venous hypertension. The present observational cohort study was to determine healing and RR in VLU treated with ultrasound-guided foam sclerotherapy (UGFS). One hundred and eighty VLU were treated with polidocanol microfoam monthly under ultrasound control. Median follow-up was 30 months (range: 17-40). One hundred seventy-two (95.6%) ulcers healed during the study. The overall twenty-four week HR was 79.4% and was significantly higher (95.1%) in patients with isolated great saphenous vein incompetence than in those with great saphenous vein plus perforator (91.7%) or exclusive perforator incompetence (78.9%) (p < 0.01). Patients without deep vein incompetence had a significantly higher 6-month HR (89.8%) than those with (67.4%) (p < 0.01). Multivariate analysis identified the following independent risk factors: chronicity > 12 months (OR 7.69), area > 6 cm(2) (OR 4.24), lipodermatoesclerosis (OR 12.22), history of > 3 previous ulcers (OR 5.57) and history of deep vein thrombosis (OR 6.18). One, two and three year ulcer RR were 8.1%, 14.9%, and 20.8%, respectively. Isolated perforator incompetence and previous history of venous surgery were significantly (p = 0.03) associated with a higher RR. VLU treated with microfoam sclerotherapy are associated with high HR and low mid-term RR.
下肢静脉溃疡(VLU)通常愈合速度缓慢且复发率高。其根本病因是静脉高压。本观察性队列研究旨在确定接受超声引导下泡沫硬化疗法(UGFS)治疗的VLU的愈合情况和复发率。180例VLU患者在超声引导下每月接受聚多卡醇微泡沫治疗。中位随访时间为30个月(范围:17 - 40个月)。在研究期间,172例(95.6%)溃疡愈合。总体24周愈合率为79.4%,单纯大隐静脉功能不全患者的愈合率显著更高(95.1%),高于大隐静脉合并交通支功能不全患者(91.7%)或单纯交通支功能不全患者(78.9%)(p < 0.01)。无深静脉功能不全的患者6个月愈合率(89.8%)显著高于有深静脉功能不全的患者(67.4%)(p < 0.01)。多因素分析确定了以下独立危险因素:病程>12个月(比值比7.69)、面积>6 cm²(比值比4.24)、脂肪皮肤硬化症(比值比12.22)、既往溃疡史>3次(比值比5.57)和深静脉血栓形成史(比值比6.18)。溃疡1年、2年和3年复发率分别为8.1%、14.9%和20.8%。单纯交通支功能不全和既往静脉手术史与较高的复发率显著相关(p = 0.03)。接受微泡沫硬化疗法治疗的VLU愈合率高且中期复发率低。
