Deep venous thrombosis after emergency gastrointestinal operations: a pilot study

Area of Science:

• Vascular Surgery
• Thrombosis Research
• Gastrointestinal Surgery

Background:

• Major emergency gastrointestinal surgery poses a significant risk for postoperative deep venous thrombosis (DVT).
• Routine thrombosis prophylaxis was not standard for emergency surgical patients at the time of the study.
• Individualized prophylaxis decisions were made by surgeons regarding low-dose heparin administration.

Purpose of the Study:

• To evaluate the incidence of DVT in patients over 50 undergoing major emergency gastrointestinal surgery.
• To assess the efficacy of low-dose heparin prophylaxis in preventing DVT in this high-risk population.

Main Methods:

• A prospective pilot study involving 30 patients aged over 50.
• Utilized the 125I-fibrinogen uptake test to diagnose DVT postoperatively.
• Low-dose heparin (5,000 units twice daily) was administered at the surgeon's discretion.

Main Results:

• Deep venous thrombosis (DVT) was diagnosed in 37% of patients (11 out of 30).
• Five patients experienced bilateral DVT.
• No DVT occurred within seven days in patients receiving early low-dose heparin prophylaxis.

Conclusions:

• Major emergency gastrointestinal surgery is associated with a high risk of DVT.
• Early initiation of low-dose heparin prophylaxis appears effective in preventing DVT in this patient group.
• Further research is warranted to confirm these findings in a larger cohort.
