Abstract

GUIMARAES, Thiago Adriano Silva et al. Morphological aspects of mural thrombi deposition residual lumen route in infrarenal abdominal aorta aneurisms. Acta Cir. Bras. [online]. 2008, vol.23, suppl.1, pp.151-156. ISSN 1678-2674.  https://doi.org/10.1590/S0102-86502008000700024.

PURPOSE: To assess the most frequent deposition site of mural thrombi in infrarenal abdominal aorta aneurisms, as well as the route of the residual lumen. METHODS: Assessment of CT scan images from 100 patients presenting asymptomatic abdominal aorta aneurism, and followed at HC-FMRP-USP. RESULTS: In 53% of the cases the mural thrombus was deposited on the anterior wall; from these, in 22%, the residual lumen described a predominantly right sided route; in 22%, a left sided route; on the mid line in 5%; and crossing over the mid line in 1%. In 23%, the deposition of thrombi was concentric. In 11% it occured on the posterior wall; from these, in 5%, the route of the residual anterior lumen was predominantly right sided; in 5%, left sided; and crossed over the mid line in 1%. In 13% complex morfological deposition patterns were found. CONCLUSION: Mural thrombi formation was predominantly found on the anterior wall of the aneurismatic mass, with the route of the residual lumen projecting towards the posterior wall.
