Transluminal Coil Embolization of an Inferior Gluteal Artery Aneurysm by Ultrasound-guided Direct Puncture of the Target Vessel

Abstract

Pseudoaneurysms of the inferior gluteal artery are rare. We describe a case of an inferior gluteal pseudoaneurysm that presented as a painful mass in the buttock. A percutaneous thrombin injection under ultrasound guidance failed to occlude the sac, probably due to the wide neck of the aneurysm. Subsequently, transluminal coil embolization by ultrasound-guided direct puncture of the inferior gluteal artery achieved complete thrombosis of the sac. Ultrasound-guided coil embolization is recommended in the treatment of peripheral aneurysms where catheter placement using conventional interventional procedures is difficult.

Preparation and characterization of injectable fibrillar type I collagen and evaluation for pseudoaneurysm treatment in a pig model

“…11 Several cases reported thrombin failure in these complex pseudoaneurysms. [12][13][14] The soluble thrombin may quickly diffuse through the wide neck of the pseudoaneurysm toward the lumen of the artery. In most cases, these complex pseudoaneurysms need to be revised surgically.…”

“…11 Several cases have reported thrombin failure in these complex pseudoaneurysms. [12][13][14] Particularly in these cases, injectable collagen may be an attractive agent, since collagen is highly viscous and collagen fibrils aggregate and deposit at the site of injection. In one study, the potentials of injectable collagen for PSA treatment in patients was described, and a very high success rate was reported.…”

Inferior gluteal artery pseudoaneurysm mimicking gluteal abscess

“…Transluminal coil embolisation by ultrasound guided direct puncture has also been suggested for inferior gluteal artery aneurysm [13]. Thrombin injection is also a useful method in pseudoaneurysms with narrow neck [14].…”

“…Treatment is achieved by open surgery or minimally invasive techniques, such as embolization during angiography [1,3,4,7,12,13]. Transluminal coil embolisation by ultrasound guided direct puncture has also been suggested for inferior gluteal artery aneurysm [13].…”
