Case report of varicose veins treatment in patient with a prosthetic mitral valve

Abstract

This clinical case may be of interest in situations where a patient with varicose veins of the lower limbs and concomitant heart disease, who is on long-term anticoagulant therapy and is scheduled to undergo minor surgery, may present the possibility of endovenous laser ablation (EVLA) against the background of warfarin use. Patient, G., 68 years old, with rheumatic combined mitral valve disease (mitral valve replacement in 2019, permanent atrial fibrillation), also had varicose vein disease of the lower limbs. History included acute cerebrovascular accident (19.01.2023). Duplex Ultrasonography Screening (DUS) showed failure of the left great saphenous vein valve. Hypocoagulation was also observed in coagulogram and the risk of bleeding on HAS-BLED score was average. On Caprini score, the risk was very high. Endovenous laser ablation of the large saphenous vein on the left side was performed. During follow-up examinations, there were no signs of bleeding from puncture sites. The target trunk was obliterated in dynamics at DUS. Therefore, it is possible to carry out EVLA of a large subcutaneous vein while taking therapeutic doses of warfarin without switching to bridge therapy. Endovascular laser ablation allowed it to be done with less risk of bleeding and, against the background of taking warfarin, reduced the risk of thrombosis.
