However, growing experimental and clinical evidence shows that its effects extend beyond the venous system, influencing tissue fluid balance, lymphatic function, arterial perfusion, microcirculation, and inflammation. This suggests that its clinical benefits arise from a global effect on the compressed structures rather than from isolated vascular effects.Study Aimto highlight two key concepts: first, that the effects of compression depend not only on resting pressure but also on its dynamic behavior and stiffness; and second, that compression acts simultaneously on all structures within the compressed segment, irrespective of the primary clinical indication.MethodsWe critically reviewed and integrated evidence from experimental studies, imaging, clinical investigations, randomized controlled trials, systematic reviews, consensus documents, and international guidelines into a mechanism-based framework. Rather than adopting a disease-oriented approach, the review organized the evidence around the biological targets through which compression exerts its therapeutic effects.ResultsCompression therapy works by delivering a controlled mechanical stimulus to the entire compressed segment, thereby improving venous hemodynamics, lymphatic drainage, microvascular function, and arterial perfusion, while regulating inflammation. These interconnected mechanisms explain the efficacy of compression across different vascular disorders. Therapeutic benefit depends on compression characteristics, including not only interface pressure but, most importantly, material stiffness, dynamic pressure changes during movement, treatment duration, and patient adherence. The review also shows that much of the heterogeneity in the literature reflects methodological limitations rather than conflicting biological effects.ConclusionsCompression therapy should be viewed as a biomechanical intervention that restores tissue homeostasis, with vascular changes reflecting coordinated downstream responses. This integrated framework offers a unifying explanation of its biological effects, supports individualized treatment planning, and identifies priorities for improving the design and interpretation of future clinical studies.</p>","PeriodicalId":94350,"journal":{"name":"Phlebology","volume":" ","pages":"2683555261494672"},"PeriodicalIF":1.5,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149121656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The search period was from the database establishment to April 20, 2026. Two researchers independently screened the literature, extracted data, and evaluated methodological quality according to inclusion and exclusion criteria, and then performed a Meta-analysis.ResultsA total of 12 randomized controlled trials involving 1206 patients were ultimately included. Meta-analysis results demonstrated that the patients in the compression stocking group had higher ulcer healing rates compared to the control group [<i>RR</i> = 1.39, 95%<i>CI</i> (1.11, 1.74), <i>P =</i> .004], a greater reduction in ulcer wound area [<i>MD</i> = 5.10, 95%<i>CI</i> (1.60, 8.60), <i>P</i> < .01], and lower ulcer recurrence rates [<i>RR</i> = 0.56, 95%<i>CI</i> (0.37, 0.84), <i>P</i> < .01]. Subgroup analyses indicated that intervention duration could potentially have a modifying effect: interventions lasting ≤12 weeks showed beneficial outcomes, but longer-duration treatments did not, though the between-subgroup difference test did not yield a significant result. Subgroup analysis stratified by stocking layer type found that two-layer compression stockings delivered significant healing benefits, although the between-subgroup difference test did not return a significant result. Sensitivity analysis, which excluded two studies using atypical comparators, confirmed that the healing-rate result was robust. However, no statistically significant differences were observed in adverse event incidence or ulcer healing time between the compression stocking group and the control group [<i>RR</i> = 0.87, 95%<i>CI</i> (0.63, 1.20), <i>P</i> = .40] and [<i>MD</i> = -1.19, 95%<i>CI</i> (-6.85, 4.47), <i>P</i> = .68], respectively. The evidence quality for the indicators of adverse event incidence was of moderate quality, while the rest were of low quality.ConclusionBased on limited evidence, compared with other compression modalities, compression stockings are associated with higher ulcer healing rates, greater wound area reduction, lower recurrence rates, and have favourable safety profiles. However, compression stockings do not outperform other compression modalities across all measured outcomes, as no significant difference was observed in healing time.

This feasibility study aimed to assess the effectiveness of routinely prescribed non-steroidal anti-inflammatory drugs (NSAIDs) for pain management following treatment for SVI, and to examine the feasibility of conducting a randomised controlled trial (RCT).MethodsEligible patients undergoing endovenous thermal ablation (EVTA) and/or concomitant phlebectomy for SVI were enrolled.

The control group received standard intraoperative thromboprophylaxis; the experimental group added intraoperative NMES on the basis of standard prophylaxis. We compared perioperative plasma D-dimer, popliteal vein diameter and blood flow velocity, 24-h postoperative DVT incidence after fascial closure, and NMES-related adverse events between groups. <b>Results:</b> The incidence of deep vein thrombosis in the lower extremities 24 hours after fascial closure was lower in the experimental group than in the control group (χ<sup>2</sup> = 4.145, <i>p</i> = .042); Following surgery, the popliteal vein blood flow velocity in both lower limbs of the experimental group was significantly faster than that of the control group (<i>p</i> < 0.05), while there was no significant difference in the diameter of the popliteal veins between the two groups; there was no statistically significant difference in plasma D-dimer levels between the two groups (<i>p</i> > .05), and no adverse events related to the use of the neuromuscular stimulator occurred in the experimental group. <b>Conclusions:</b> The use of a neuromuscular electrical stimulator during surgery in patients undergoing lithotomy position procedures can accelerate the venous flow rate of lower limb veins, alleviate venous stasis in the lower limbs caused by the placement of lithotomy positions, and help to prevent the occurrence of DVT.</p>","PeriodicalId":94350,"journal":{"name":"Phlebology","volume":" ","pages":"2683555261490357"},"PeriodicalIF":1.5,"publicationDate":"2026-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149043078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
