Inferior gluteal artery pseudoaneurysm related to intramuscular injection

Abstract

HighlightsA case of pseudoaneurysm of the IGA following intramuscular injection in the buttock.Importance careful physical examination in order to avoid misdiagnosis.Diagnosis and therapy are facilitated by catheter angiography.

Pseudoaneurisma da artéria glútea inferior após queda de bicicleta: relato de caso

“…An incorrect diagnosis of a local abscess can have catastrophic consequences. 1,3,4 In the case described here, the signs observed were painful, non-pulsating hematoma of the right gluteal region.…”

“…4 When a person falls onto the ground or other rigid surface, suffering a blunt trauma, the inferior gluteal artery and its branches are more likely to be injured than the superior gluteal artery, because of the paths they take through the gluteal region. 1,3 Fewer than 150 cases of pseudoaneurysms of the gluteal artery have been described in the literature to date. 5 These injuries more commonly involve the superior gluteal artery and are related to penetrating traumas, iatrogenic injuries during pelvic or hip surgery, or fractures of pelvic bones, or occur after intramuscular injections.…”

“…Aneurysms of the gluteal arteries are rare conditions, accounting for less than 1% of all aneurysms. [1][2][3] The superior and inferior gluteal arteries are involved more frequently, while aneurysms of the persistent sciatic artery are less common. With these arteries, pseudoaneurysms are more common than true aneurysms, and frequency is greatest in the superior gluteal artery.…”

“…With these arteries, pseudoaneurysms are more common than true aneurysms, and frequency is greatest in the superior gluteal artery. 1 Reports published during the last 30 years describe pseudoaneurysms of the inferior gluteal artery caused by penetrating traumas, fractures of bones of the pelvis, or iatrogenic injuries during surgical procedures involving the pelvis or hips. 1 Pseudoaneurysms of the inferior gluteal artery after blunt trauma are even rarer, with just six cases reported in the literature.…”
