Spinal angiolipomas are rare benign tumors composed of mature adipocytes mixed with abnormal vessels. They represent 0.0004 to 1.2% of angiolipomas, usually located at the extradural and posterior thoracic level, with multimetameric extension. Spinal angiolipoma is an uncommon form of benign tumor. There are 2 types: non-infiltrating and infiltrating. Its clinical course is slow and progressive, and it can be accelerated by vascular phenomena, intratumoral abscess and pregnancy. Intratumoral bleeding must be considered a cause of acute spinal compression syndrome. Spinal epidural angiolipoma is a rare, slow-growing and progressive benign tumor. MRI is the gold standard for diagnosis. The gold standard treatment must always be surgery, although total resection may not be possible in some cases.

The need to find the lowest possible effective dose of clonidine to avoid its known side effects such as hypotension, bradycardia and sedation motivated us to design the present study. We compared different doses of clonidine as an adjuvant to intrathecal bupivacaine for spinal anesthesia in patients undergoing cesarean section in order to find the lowest possible effective dose. Spinal anesthesia is a safe, reliable and inexpensive technique, with the advantage of providing surgical anesthesia and prolonged postoperative pain relief, in addition to attenuating autonomic, somatic and endocrine responses to surgical stimulation.
