Autopsy of a 59-year-old woman revealed chronic heart failure, an aberrant right subclavian artery occluded by thrombosis, and acute infarction of the left cerebellar hemisphere.
Case Report (n=1)
This case report describes a rare co-occurrence of aberrant right subclavian artery thrombosis and acute left cerebellar hemisphere infarction in a patient who died of chronic heart failure.
Rare association in fatal heart failure warrants no practice change; hypothesis-generating for subclavian thrombosis as cerebellar infarct mechanism.
Anomalies of the aortic arch and its main branches are rare; estimations from autopsy series indicate a frequency of 3%. The incidence of an aberrant right subclavian artery is up to 0.5% of the population. � Aputrefiedcorpseof�59-yearoldwomenwasfoundinherlockedapartmentseatinginarmchair.�Theautopsyasadirect� cause of death revealed chronic heart failure.

Stojanović et al. (2011) conducted a case report in Thrombosis of aberrant right subclavian artery and left cerebellar hemisphere infarction (n=1). Aberrant right subclavian artery thrombosis was evaluated on Autopsy findings. Autopsy of a 59-year-old woman revealed chronic heart failure, an aberrant right subclavian artery occluded by thrombosis, and acute infarction of the left cerebellar hemisphere.
