Review Case Reports
Vascular compression syndrome of sciatic nerve caused by gluteal varicosities.
Sciatica is defined as pain or discomfort along the regions innervated by the sciatic nerve. Compression or irritation of lumbar spinal roots, most commonly because of lumbar disc herniation or spinal stenosis, causes sciatica in the vast majority of cases. Although it is rather uncommon, many pathologies have reported to cause nondiscogenic sciatica. ⋯ Given the atypical presentation of spinal root compression, gluteal vascular compressive neuropathy was suspected. Ligation and resection of varicotic vein resulted in relief of the patient's pain. To our knowledge, cases with varicosity-caused sciatica were limited in the literature review.

Chronic stump and phantom limb pain after amputation for critical ischemia significantly affect patients' quality of life and pose challenging clinical problems. Pre-emptive analgesia attempts to prevent chronic postoperative pain by minimizing painful stimuli before and during surgery. ⋯ There is no robust evidence supporting the use of pre-emptive analgesia to minimize the risk of chronic pain after amputation for critical ischemia of peripheral vascular disease. The methods used are, however, effective in treating acute postoperative pain.
