We recommend periodic monitoring of patients with increased INR, decreased fibrinogen, and decreased platelet count. Patients should be monitored for 10 to 14 days after envenomation to identify asymptomatic rebound coagulopathy. Prompt readministration of FabAV appears to correct the coagulopathy.

This case study presents a rare iliac vascular injury in the absence of a pelvic fracture. A 36-year-old man sustained a blunt injury after being stuck by a motor vehicle. The only positive computed tomographic finding was in the pelvis that showed a 4 × 2-cm left retroperitoneal soft-tissue collection, appearing to encompass the left common and left external iliac veins. A pelvic venogram was obtained on Day 2 revealing a focal injury to the left external iliac vein with 60% narrowing. The patient was treated with clopidogrel and acetylsalicylic acid and discharged from the hospital to his home 3 days later. A follow-up pelvic venogram in 6 weeks later showed complete healing of previously visualized left external iliac venous injury without any residual stenosis.
