Spontaneous spinal epidural hematoma following IV heparin and catheter-directed thrombolysis for deep vein thrombosis

Spontaneous spinal epidural hematoma (SSEH) is a rare condition, and it usually presents with acute onset neck or back pain, progressive weakness, and other symptoms of spinal cord compression. Catheter-directed thrombolysis is one option for limbs threatened by iliofemoral venous thrombosis; other options, such as venous thrombectomy (either open or percutaneous), are also available. There are few reported cases of SSEH owing to catheter-directed thrombolysis for deep venous thrombosis (DVT). We present a case of a 65-year-old man who presented with left lower limb extensive iliofemoral DVT and received catheter-directed thrombolysis. The patient initially had rapid improvement in his symptoms with restoration of limb perfusion. However, within 6 hours of starting catheter-directed thrombolysis, the patient developed extensive SSEH and underwent emergent spinal decompression surgery with laminectomy of T11 to T12 with complete resolution of the neurological deficit. Clinicians should consider SSEH in differential diagnosis if the patient develops acute onset neck or back pain after catheter-guided thrombolysis for DVT.
