Pseudoaneurysm of the inferior gluteal artery presenting as sciatic nerve compression

ABSTRACT A pseudoaneurysm of the inferior gluteal artery presenting as sciatic nerve compression is reported in a 40-year-old woman. Following a transvaginal needle biopsy for endometriosis, the patient developed left sciatic pain and a nonpulsatile mass palpable in the left buttock thought to represent a pyriformis hematoma. Sequential computed tomographic scans were consistent with this diagnosis. Persistent pain and progression of neurological deficits led to surgical exploration. Posterior exposure of the pyriformis muscle and proximal sciatic nerve revealed a large pseudoaneurysm of the inferior gluteal artery compressing the nerve. A laparotomy was performed and the internal iliac artery was ligated, followed by evacuation of the aneurysm contents and repair of the aneurysm neck via a posterior approach. The patient has remained pain-free with progressive improvement in neurological function after 1 year follow-up. Aneurysms of the gluteal artery are unusual, predominantly occur after significant pelvic trauma, and rarely present as sciatica. Pertinent aspects of the patient history and clinical findings are atypical for discogenic sciatica. Because of the rarity of this entity, preoperative diagnosis is usually not achieved. Angiography or magnetic resonance imaging should be performed in patients with atypical sciatica and a mass in the region of the proximal sciatic nerve, particularly after trauma.

ABSTRACT Objective: To evaluate the effects of right sciatic nerve compression and cryotherapy on muscle tissue. Methods: We used 42 male Wistar rats, subdivided in the following Groups Control, Injury 3, Injury 8 and Injury 15 submitted to nerve compression and euthanized in the 3rd, 8th and 15th day after surgery. The Cryotherapy Injury 3 was entailed treatment with cryotherapy by immersion of the animal in recipient for 20 minutes during 1 day, then animals were euthanized at the 3rd day after surgery, and the Cryotherapy Injury 8 and the Cryotherapy Injury 15 was treated for 6 days, and euthanized at the 8th and 15th day after surgery. Functional evaluation was performed by the grasping strength of the right pelvic limb. The right tibialis anterior muscles were evaluated for mass, smaller diameter and cross-sectional area. In the Cryotherapy Injury 8 and the Cryotherapy Injury 15 groups, the hydroxyproline was dosed in the right soles. Results: In the compression there was a significant difference in the Injury Groups compared with the Control Group (p<0.05). In the smaller diameter, the compression in Control Group was higher than Injury 8 (p=0.0094), Injury 15 (p=0.002) and Cryotherapy Injury 15 (p<0.001) groups. The comparison between groups with euthanasia in the same post-operative period, a significant difference (p=0.0363) was seen in day 8th after surgery, and this result in Cryotherapy Injury Group was greater than Injury Group. In the fiber area, Control Group was also higher than the Injury 8 (p=0.0018), the Injury 15 (p<0.001) and the Cryotherapy Injury 15 (p<0.001). In hydroxyproline, no significant difference was seen between groups. Conclusion: Nerve damage resulted in decreased muscle strength and trophism, the cryotherapy delayed hypotrophy, but this effect did not persist after cessation of treatment.
