Deep hypothermic total circulatory arrest for internal carotid artery aneurysm extending into the cranium: experience from a developing country.

Cardiopulmonary bypass is commonplace for acquired and congenital cardiac procedures. It has also stretched to facilitate complicated non-cardiac operations. Carotid artery aneurysms are treated both with surgical repair without cardiopulmonary bypass (CPB) and, occasionally, by utilizing CPB perfusion techniques. We have successfully repaired an internal carotid artery aneurysm, extending into cranium in a 30-year-old woman, by establishing deep hypothermic circulatory arrest on cardiopulmonary bypass.
