A systematic review and meta-analysis of concomitant truncal and perforator surgery

Incompetent perforator veins are encountered frequently during ultrasound assessment of the venous system in chronic venous disease. Some studies have shown that concomitant treatment of truncal and perforator incompetence improves ulcer healing, yet a Cochrane review was unable to determine the potential benefits of perforator surgery in venous ulcer management due to poor quality evidence. This study aims to establish the exact role of concomitant treatment in patients with chronic venous disease.

A search of online databases including MEDLINE, Embase, and Cochrane was performed in March 2022. All studies comparing the outcomes of concomitant superficial venous plus perforator surgery with standard therapy were included. Variables assessed included ulcer healing, time to healing, and ulcer recurrence. Disease severity and quality of life, vein occlusion rates, number of incompetent perforator veins on duplex ultrasound post treatment, and reintervention and complication rates were also analyzed. Data were pooled using a random effects model.

Seven studies (872 limbs) were included for analysis. Included studies were of reasonable methodological quality. Ulcer healing rates were similar in each group (relative risk [RR], 1.07; 95% confidence interval [CI] 0.96-1.19; P = .23). Two studies reported no difference in mean time (days) to ulcer healing between groups (mean difference, -14.60; 95% CI, -34.57 to 5.38; P = .15; I² = 0%; P = .56). Ulcer recurrence was significantly lower in the concomitant group (3.7% vs 44%) (RR, 0.21; 95% CI, 0.07- 0.65; P = .007; I² = 43%; P = .17). Overall, there was no difference in disease severity measured at 12-month follow-up, with a weighted mean difference between groups of -0.88 (95% CI, -2.05 to 0.29; P = .14; I² = 84%; P = .002). Quality of life was reported in only one study. The total number of perforator veins identified at follow-up duplex ultrasound was significantly lower in the concomitant group (22.4% vs 89%) compared with standard therapy (RR, 0.31; 95% CI, 0.19-0.53; P < .0001; I² = 88%; P = .0002). There was no difference between groups for occlusion rates of treated great saphenous vein or incompetent perforators (RR, 2.22; 95% CI, 0.10-49.74; P = .61). Reported minor (RR, 0.98; 95% CI, 0.63-1.52; P = .92) and thrombotic complications (RR, 2.04; 95% CI, 0.59-6.99; P = .26) were similar between groups.

Concomitant truncal and perforator surgery is comparable to standard therapy in terms of ulcer healing, safety, and efficacy. Meta-analysis suggests that concomitant treatment could significantly reduce ulcer recurrence rates, but included studies were subject to some biases and short follow-up. Concomitant treatment may be considered to prevent recurrence rather than improve ulcer healing.
