Postprocedural hypotension developed in 25% (36/146) of patients after 23% (37/60) carotid artery stent (CAS) placements through a transfemoral approach performed by two vascular surgeons. These patients had significantly longer intensive care unit and hospital stays than those who did not develop post-CAS hypotension. Hypotension was significantly associated with severe lesion calcification and contrast material volume. Of the stents used, the Precise stent (Cordis Corporation, Cardinal Health Company, Milpitas, Calif) caused hypotension most commonly (70%) and the Xact stent (Abbott Vascular, Abbott Park, Ill) the least commonly (41%). The embolic protection device Angioguard (Cordis Corporation) was associated with hypotension most commonly, whereas the FilterWire EZ (Boston Scientific, Marlborough, Mass) was associated with hypotension the least commonly (51% vs 42%, respectively).
