Background and Study Scale<\/strong><\/h3>\n<p>This systematic review synthesized evidence from\u00a0<strong>11 studies<\/strong>\u00a0(comprising 3 randomized controlled trials and 8 cohort studies), encompassing a total sample size of\u00a0<strong>13,089 patients<\/strong>. The objective was to evaluate the efficacy of the hemodynamic-based CHIVA method relative to traditional destructive surgical techniques.<\/p>\n<p><strong>Distribution of Patient Cohorts:<\/strong><\/p>\n<ul>\n<li><strong>CHIVA Group:<\/strong>\u00a06,908 cases<\/li>\n<li><strong>Conventional Stripping Group:<\/strong>\u00a05,988 cases<\/li>\n<li><strong>Endovenous Laser Ablation (EVLA) Group:<\/strong>\u00a0110 cases<\/li>\n<li><strong>Radiofrequency Ablation (RFA) Group:<\/strong>\u00a083 cases<\/li>\n<\/ul>\n<h3 class=\"wp-block-heading\"><strong>III. Core Research Findings<\/strong><\/h3>\n<h4 class=\"wp-block-heading\"><strong>1. Superior Outcomes (Favoring CHIVA)<\/strong><\/h4>\n<ul>\n<li><strong>Saphenous Nerve Injury:<\/strong>The risk of nerve injury was significantly lower in the CHIVA group compared to the stripping group ($RR: 0.07; 95\\% \\text{ CI}: 0.02, 0.22; P &lt; 0.0001$). CHIVA also demonstrated a superior safety profile compared to thermal ablation techniques (EVLA\/RFA) ($RR: 0.14; 95\\% \\text{ CI}: 0.03, 0.74; P = 0.02$).<\/li>\n<li><strong>Postoperative Ecchymosis:<\/strong>CHIVA significantly reduced the incidence of postoperative bruising compared to alternative treatments ($RR: 0.62; 95\\% \\text{ CI}: 0.54, 0.71; P &lt; 0.0001$).<\/li>\n<\/ul>\n<h4 class=\"wp-block-heading\"><strong>2. Clinical Equivalence<\/strong><\/h4>\n<p>No statistically significant differences were observed between CHIVA and the control groups (stripping or ablation) regarding the following parameters:<\/p>\n<ul>\n<li>Recurrence rates<\/li>\n<li>Thrombophlebitis<\/li>\n<li>Wound infections<\/li>\n<\/ul>\n<h3 class=\"wp-block-heading\"><strong>IV. Conclusion and Recommendations<\/strong><\/h3>\n<p>The study concludes that the\u00a0<strong>CHIVA technique<\/strong>\u00a0offers distinct advantages in minimizing postoperative saphenous nerve injury and ecchymosis. Furthermore, it maintains equivalence to conventional destructive methods in terms of long-term recurrence and infection risks, supporting its role as a viable, conservative hemodynamic alternative.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<div class=\"post_bottom_wr \">\n    <div class=\"post_bottom media\">\n\t<div class=\"tags media-body\"><a

Analyzing data from 11 studies and over 13,000 patients, the research demonstrates that CHIVA significantly reduces the risk of saphenous nerve injury and postoperative ecchymosis while maintaining equivalent results in recurrence rates and safety profiles. This study reinforces CHIVA\u2019s position as a superior, minimally invasive alternative for venous disease management.<\/p>","protected":false},"author":1,"featured_media":7674,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[117],"tags":[129,128,118,131],"class_list":["post-7782","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-insights-news","tag-chiva","tag-hemodynamics","tag-varicose-veins","tag-venous-disease"],"_links":{"self":[{"href":"https:\/\/asianvenousacademy.org\/zh\/wp-json\/wp\/v2\/posts\/7782","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/asianvenousacademy.org\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/asianvenousacademy.org\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/asianvenousacademy.org\/zh\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/asianvenousacademy.org\/zh\/wp-json\/wp\/v2\/comments?post=7782"}],"version-history":[{"count":4,"href":"https:\/\/asianvenousacademy.org\/zh\/wp-json\/wp\/v2\/posts\/7782\/revisions"}],"predecessor-version":[{"id":7786,"href":"https:\/\/asianvenousacademy.org\/zh\/wp-json\/wp\/v2\/posts\/7782\/revisions\/7786"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/asianvenousacademy.org\/zh\/wp-json\/wp\/v2\/media\/7674"}],"wp:attachment":[{"href":"https:\/\/asianvenousacademy.org\/zh\/wp-json\/wp\/v2\/media?parent=7782"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/asianvenousacademy.org\/zh\/wp-json\/wp\/v2\/categories?post=7782"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/asianvenousacademy.org\/zh\/wp-json\/wp\/v2\/tags?post=7782"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
