Revival of Ancient Therapies: Leech Therapy in Modern Management of Deep Vein Thrombosis – A Case Study

Deep Vein Thrombosis (DVT) is a serious vascular condition characterized by blood clot formation in deep veins, typically in the lower limbs. Conventional treatments involve anticoagulants, which carry risk of bleeding and other side effects. This case study investigates the efficacy of leech therapy, a traditional Unani treatment, as an alternative approach in managing DVT. A 65-year-old male presented with calf pain, swelling, and mild discoloration in the left leg for 30-40 days. Venous Color Doppler confirmed acute thrombosis extending to the external iliac veins. The patient underwent weekly leech therapy sessions for 4 weeks, along with consumption of Sharbat Faulad to maintain hemoglobin levels. Pain scores reduced from 8/10 before treatment to 1/10 by the end of therapy, with significant improvement in mobility. The patient’s walking distance increased from 30 meters in the first week to 300 meters by the fourth week. Post-therapy doppler imaging showed a significant reduction in thrombus size and improved venous circulation. Leech therapy proved to be an effective, non-invasive treatment for DVT, reducing thrombus size and alleviating symptoms without the side effects associated with pharmacological anticoagulants. This case highlights the potential of Unani regimenal therapies as viable alternatives in modern healthcare, particularly for managing vascular conditions like DVT.
