Diagnosis and management of a giant retroperitoneal hematoma compressing the femoral nerve, following an ultrasound-guided lumbar sympathetic block: a case report.

ABSTRACT:

Background

The lumbar sympathetic nerve block stands as a pivotal approach in managing complex regional pain syndrome (CRPS) in the lower limbs. Retroperitoneal hemorrhage is an extremely rare and severe complication of lumbar sympathetic nerve block. Here, we report for the first time a case of retroperitoneal hemorrhage that initially presented with symptoms of femoral nerve compression.
