Segmental point obliteration technique (SPOT) for nerve-sparing endovenous laser ablation of the below-knee great saphenous vein

Chih-Chun Yang, MD · JVS–CIT · 13 patients, 19 limbs · 1 month

Intermittent point-by-point energy delivery was explored in the below-knee great saphenous vein. All 19 limbs were occluded at one month, with no reported saphenous paresthesia. The small sample, absent comparator and brief follow-up prevent conclusions about comparative benefit.

The sheathless ultrafine laser ablation technique for managing deep muscle branch reflux in hostile anatomy following rhabdomyosarcoma resection

Chih-Chun Yang, MD · JVS–CIT · 1 patient · 3 months

A 400 μm fiber passed directly through an 18G catheter to treat a 1.5 cm refluxing deep muscle branch. Occlusion was confirmed at three months in one patient. Broader applicability and long-term outcomes remain uncertain.
