    Intravenous heparin during aorto-femoral reconstruction showed insignificant correlation between limb swelling and deep vein thrombosis (DVT). Most ankle swelling cases were transient, with few permanent cases and minimal DVT occurrence.

    Area of Science:

    • Vascular Surgery
    • Thrombosis Research
    • Postoperative Complications

    Background:

    • Aorto-femoral reconstruction is a major vascular procedure.
    • Intravenous heparin is commonly used perioperatively to prevent thrombosis.
    • Postoperative limb swelling and deep vein thrombosis (DVT) are potential complications.

    Purpose of the Study:

    • To evaluate the incidence and relationship between ankle swelling and DVT after aorto-femoral reconstruction using i.v. heparin.
    • To determine if limb swelling is a reliable indicator of DVT in this patient cohort.

    Main Methods:

    • Retrospective review of 30 patients undergoing aorto-femoral reconstruction with i.v. heparin.
    • Analysis of operated and non-operated limbs for ankle swelling.
    • Assessment for the occurrence of deep vein thrombosis (DVT).

    Main Results:

    • Ankle swelling occurred in 12 of 60 operated limbs (20%), with 9 transient and 3 permanent cases.
    • One non-operated limb experienced swelling.
    • Deep vein thrombosis (DVT) occurred in 7 limbs; swelling was coincident in only 3 cases, with 1 permanent swelling.

    Conclusions:

    • The coincidence of limb swelling and DVT following aorto-femoral reconstruction with i.v. heparin is statistically insignificant.
    • Limb swelling alone is not a definitive predictor of DVT in patients undergoing this procedure.
    • Careful diagnostic evaluation is necessary to confirm DVT, irrespective of limb swelling.
