Mycotic Aneurysm of the Internal Carotid Artery

Abstract

A 17-year-old man presented with signs of rupture of a high cervical internal carotid aneurysm. Following angiographic demonstration of the aneurysm, he was immediately treated by balloon catheter occlusion. Eight days later the ligation of the supraclinoid portion of the internal carotid on the left was prompted by the formation of blood clots and emboli from this segment. The patient tolerated both procedures well.

Pseudomonas aeruginosa Causing a Right Carotid Artery Mycotic Aneurysm After a Dental Extraction Procedure

“…Other than our case, 5 case reports of carotid mycotic aneurysm as a complication of underlying dental infection or extractions were found. [43][44][45][46][47] The mortality rate was 17% for these cases with a mean follow-up of 5 1 /2 months. The first report was that of an 11-year-old boy with an extensive Penicillium infection and associated rupture of his aneurysm, which developed after a maxillary tooth extraction.…”

“…The third case was that of an internal carotid mycotic aneurysm developing in a 17-year-old boy after a wisdom tooth extraction. 44 "Enterococci" were isolated at surgery. This patient was treated with balloon thrombosis and aneurysm clipping.…”

Microbial Extracranial Aneurysm of the Internal Carotid Artery: Complication of Cervical Lymphadenitis

“…Reported treatments of microbial pseudoaneurysms are balloon catheter occlusion, 8 ligation, resection, and reconstruction. [10][11][12] As several complications were reported after carotid ligation, ' l an anastomosis between the intracranial internal carotid artery and the extracranial internal carotid artery was added to the ligation in our patient.…”

“…In a few cases, the rupture of a mass was reported with a large pseudoaneurysm. 8 We describe a pédiatrie case of a small pseudoaneurysm diagnosed by dynamic magnetic resonance imaging (MRI) in the early stage and describe the clinical course.…”

Extracranial infected carotid artery aneurysm

“…Reported surgical therapy for extracranial infected carotid artery aneurysms tion 7,[14][15][16]. The bacterial pathogens in the other four cases were not typical of oral flora and included Enterococcus, Salmonella, Pseudomonas, and Klebsiella plus Bacteroides.…”
