BACKGROUND: False aneurysm formation occurs in 13-49% of internal carotid artery dissections (ICADs). In light of the uncertainty regarding the clinical course, expansion rates and optimal treatment of post-ICAD false aneurysms, a systematic review of the literature was undertaken to establish the fate of the nonoperated distal ICA false aneurysm after ICAD.
METHODS: PubMed/MEDLINE, Embase, and Cochrane databases were systematically searched up to 13 August 2015 for studies reporting clinical outcomes and imaging surveillance in patients who were found to have developed a false aneurysm associated with ICAD, with specific emphasis on the fate of the nonoperated false aneurysm.
RESULTS: Eight studies reported on the course/clinical outcome of ICAD-associated false aneurysms in 166 patients. Of these, five of 166 false aneurysms (3%) increased in size; 86 of 166 (52%) remained unchanged in diameter; 35 of 166 (21%) diminished in size; 32 of 166 (19%) resolved completely; three of 166 (2%) thrombosed; and five 166 (3%) were repaired surgically. Another four of 166 (2%) underwent late surgery (0.5-5.0 years later). During the course of surveillance, none of the nonoperated false aneurysms associated with spontaneous ICAD gave rise to any new neurological or compressive symptoms.
CONCLUSIONS: In this systematic review, >95% of nonoperated false aneurysms affecting the distal internal carotid artery that developed after an ICAD did not increase in size and were not associated with any delayed neurological symptoms suggesting that conservative management and serial surveillance is the optimal mode of treatment. As nearly all studies suffered from serious bias, reporting standards for diagnosis and follow-up are needed in order to better define their natural history.
