ABSTRACT
OBJECTIVE:
Patients with chronic venous disease (CVD) can present with different underlying hemodynamic abnormalities affecting the deep, superficial, and perforator veins. This review explores the relationship between reflux patterns, extent of venous reflux, and clinical manifestations of CVD.METHODS:
The Medline and EMBASE databases were searched systematically from 1946 to April 1, 2024. References of shortlisted papers were searched for relevant articles. Studies were included if they were in English language, included participants ≥16 years of age, documented reflux patterns in two or more of the following deep, superficial, and/or perforator systems, and related patterns to presentation or severity. Exclusion criteria included patients with isolated deep venous thrombosis, post-thrombotic syndrome or stenotic or obstructive disease.RESULTS:
We identified 18 studies (11,177 participants; range, 55-3016). Meta-analysis showed significant odds ratios (OR) for C4-6 disease being associated with deep reflux (OR, 2.41; 95% confidence interval [CI], 1.53-3.78) and perforator reflux (OR, 3.37; 95% CI, 2.16-5.27), but not superficial reflux (OR, 2.11; 95% CI, 0.87-5.14), vs C0-3 disease. Severe CVD (C4-6) was significantly associated with isolated deep, combined deep and superficial, and combined superficial and perforator reflux. The greatest risk of CVD progression (defined as de novo development of varicose veins and progression to greater CVD severity) was shown by two studies to be related to combined deep and superficial reflux.CONCLUSIONS:
Although limited by the heterogenous nature of the studies, this review confirms that reflux pattern is a significant predictor of clinical class, and higher clinical, etiological, anatomical, and pathophysiological stages are associated with a higher prevalence of superficial, deep, and perforator reflux. Isolated deep and combined reflux also seem to be to predict the onset of leg ulceration. Future studies should relate reflux patterns to treatment outcomes, including recurrence risk. This work could help to inform health policies and management guidelines so that reflux patterns, in conjunction with other demographic and hemodynamic parameters, could be used to risk stratify patients and identify individuals who may benefit from earlier treatment.
