Implication

Prospective cohort study reveals high rates of asymptomatic calf vein thrombosis after colorectal cancer surgery, suggesting routine anticoagulation may not always be necessary for low-risk clots.

Key Points

To evaluate the incidence, risk factors, and clinical course of postoperative deep vein thrombosis in patients undergoing resection for colorectal malignancies without thromboprophylaxis.
Enrolled 51 consecutive patients undergoing surgery for rectal or sigmoid colon carcinoma without pharmacological or mechanical DVT prophylaxis.
Performed serial bilateral lower-limb duplex ultrasound examinations preoperatively and postoperatively to detect thrombus formation and monitor resolution.
Asymptomatic calf vein thrombosis occurred in 20 of 48 evaluable patients (41.7%), while 3 patients were excluded due to pre-existing preoperative thrombi.
Only 1 of 20 patients (5.0%) required anticoagulation due to proximal thrombus propagation, while 7 of 20 thrombi (35.0%) resolved completely within 4 weeks.
Older age and smoking history were significantly associated with postoperative thrombosis, whereas disseminated disease, procedure type, operative duration, and complications showed no association.
