A Meta-analysis of 14 High-Quality Studies Further Confirms the Minimally Invasive and Safety Advantages of CHIVA

Key Points

•Study basis: A 2023 meta-analysis published in Medicine (Baltimore) included 14 high-quality studies, including randomized controlled trials and retrospective cohort studies.

•Comparative framework: The study systematically compared ultrasound-guided CHIVA with traditional high ligation and stripping (HLS) in the treatment of varicose veins.

•Clinical endpoints: The pooled analysis showed that the CHIVA group had statistically significant advantages in operative time, intraoperative blood loss, number of incisions, length of hospital stay, and long-term recurrence control.

In the clinical treatment of lower-extremity varicose veins, eliminating reflux and improving long-term outcomes have long been central goals. At the same time, with the wider adoption of Enhanced Recovery After Surgery (ERAS) principles, perioperative safety, procedural trauma, and recovery time are becoming increasingly important in evaluating the overall clinical value of a surgical technique.

In 2023, a meta-analysis published in Medicine (Baltimore) systematically compared ultrasound-guided CHIVA with traditional high ligation and stripping (HLS), providing more concentrated evidence for the minimally invasive advantages of the CHIVA approach.

1. Background and Study Design

Although CHIVA, as a vein-preserving hemodynamic treatment strategy, has been widely discussed in the specialist field, more large-sample evidence is still needed to quantify how it compares with traditional surgery in specific clinical endpoints.

This study systematically reviewed previously published randomized controlled trials and retrospective cohort studies. After strict quality assessment and data extraction, 14 high-quality studies were ultimately included. The main purpose was to evaluate the statistical differences between CHIVA and HLS in both efficacy and safety outcomes.

2. Summary of the Main Clinical Findings

Through a rigorous meta-analysis, the study presented the performance of ultrasound-guided CHIVA across several key clinical indicators.

2.1 Better control of perioperative trauma

Compared with the traditional HLS group, the ultrasound-guided CHIVA group showed significantly better results in several indicators reflecting procedural trauma and surgical efficiency:

•shorter operative time

•less intraoperative blood loss

•fewer incisions

2.2 Reduced recovery burden and healthcare resource use

Because of its minimally invasive nature and frequent use under local anesthesia, patients in the CHIVA group had a significantly shorter length of hospital stay than those in the traditional surgery group. This also suggests strong compatibility with the ambulatory surgery model.

2.3 Encouraging long-term recurrence control

In terms of long-term prognosis, which remains a major concern in varicose vein treatment, the pooled data also showed more favorable results for CHIVA in recurrence rate when appropriate ultrasound-based hemodynamic assessment and intervention were applied.

3. Clinical Perspective: From Conceptual Debate to Evidence-Based Comparison

Placed in the broader context of surgical development, the value of this study lies not only in the comparison itself, but also in the way it moves CHIVA’s strengths from the level of theoretical hemodynamic discussion to the level of measurable clinical outcomes.

In pooled real-world evidence, CHIVA’s lower-trauma profile no longer appears merely as a byproduct of “vein preservation.” Instead, it begins to translate into visible clinical benefits. This offers an important message for vascular surgeons and specialists in venous disease: as a low-trauma and safety-oriented treatment pathway, CHIVA deserves continued attention and systematic evaluation for its potential role in improving perioperative experience and long-term patient outcomes.
