Successful treatment of post thrombotic syndrome with sequential lumbar sympathetic block.

An underappreciated sequelae of deep venous thrombosis (DVT) is the pain associated with the blood clot in the peripheral extremity. Although most frequently acute in nature, DVT occasionally presents with chronic pain in the affected limb. Furthermore, many individuals suffering from prothrombotic states often have recurring pain from DVT. Thus far there has been a paucity in the medical literature in how to treat post thrombotic pain. Post thrombotic syndrome (PTS) can cause a significant decrease in quality of life in individuals who have had a history of a DVT. Symptoms will typically include edema, pain, heaviness of the affected limb, skin changes, ulcers, varicosities, and gait abnormality. An underappreciated approach to treating PTS is the utilization of lumbar sympathetic blocks (LSB). A 68-year-old male who had a history of recurrent right lower extremity deep venous thrombosis presented with complaints of excruciating pain, discomfort, and erythema in his right lower extremity, which was negatively affecting his quality of life and prohibiting him from mobility. The patient attributed his lack of mobility secondary to the thrombotic pain. Compression boot/stocking therapy was not combating the discomfort associated with the PTS, often increasing the severity of the patient's pain. Sequential right lumbar sympathetic blocks were performed, which nearly completely resolved the patient's symptoms and improved the patient's ambulatory status and ability to perform activities of daily living. Sympathetic nerve blocks should be considered as a treatment option for patients who suffer with pain from PTS.
