Why is ecchymosis rare after CHIVA procedure compared to other treatments for varicose veins?

CHIVA is a minimally invasive technique used for treating varicose veins that involves preserving the vein network and redirecting the blood flow to healthier veins.

Ecchymosis, or bruising, is a common side effect of many surgical and minimally invasive procedures, including those used for treating varicose veins. However, CHIVA has been shown to cause much less bruising compared to other procedures such as endovenous laser ablation (EVLA) and radiofrequency ablation (RFA).

A retrospective comparative study by Dr. Smile Medical Group in China showed that less than 5% of patients with obvious ecchymosis on the second day after CHIVA surgery, while up to 100% of patients due to vein stripping surgery.

The reason for this is that CHIVA is a more selective procedure, targeting only the specific EP that are causing problems, while leaving the vein network intact. This means that less trauma is inflicted on the surrounding tissue, resulting in less bruising and a faster recovery time.

In addition, CHIVA does not involve the use of heat or chemicals, which are commonly used in other procedures and can cause tissue damage and inflammation, leading to more extensive bruising.

Overall, while some degree of bruising is still possible after a CHIVA procedure, it is generally much less severe and resolves more quickly compared to other procedures used for treating varicose veins.
