Endovenous heat-induced thrombosis (EHIT) in a 55-year-old woman experiencing left-sided groin pain, tenderness and swelling three days after endovenous laser ablation of the ipsilateral small saphenous vein. Multiplanar contrast-enhanced CT images (A, B) panoramically showed the full extent of iliac-femoral EHIT including the ipsilateral inferior hypogastric and obturator veins, with mild dilatation, luminal non-opacification and prominent enhancement of venous walls (arrows). One week later, repeated CT (C) showed persistent thrombosis of proximal femoral and obturator veins with disappeared mural enhancement (arrows) and increased mass effect on the urinary bladder. Follow-up CT three months later (D) showed recanalisation of the left femoral vein and persistence of chronic obturator vein thrombosis [Adapted from Open Access ref. no. [38]]
