Haemodynamic and Clinical Assessment of Lateral Marginal Vein Excision in Patients with a Predominantly Venous Malformation of the Lower Extremity

Objective: The purpose of the present study was to determine the effects of the surgical excision of lateral marginal veins (LMVs) in patients with a venous malformation (VM) affecting the lower extremity. Methods: Preoperative and postoperative air plethysmography (APG), CEAP classification C scores, and venous clinical severity scores (VCSS) of the 25 VM patients who underwent LMV excision were compared. Results: After LMV excision, venous haemodynamic parameters revealed significantly increased ejection fraction (EF, 33.2 S.D.18.5% vs. 39.7 S.D.21.2%, P = .020), and reduced venous volume (VV, 235.0 S.D.141.8 ml vs. 198.0 S.D.114.1 ml, P = .016) and residual venous fraction (RVF, 62.4 S.D. 26.6% vs. 56.9 S.D. 25.3%, P = .046). Clinical assessments of affected limbs revealed significantly improved mean CEAP C scores and VCSS (preoperative score, 4.4 S.D.1.7 vs. postoperative score 2.4 S.D.1.7, P = .026) after LMV excision versus preoperative data. Conclusion: Haemodynamic and clinical improvements were observed in patients with lower extremity VM after LMV excision.
