Reconstruction of Right Coronary Artery With 2 Giant Aneurysms in Series Using 3 Overlapped Covered Stents

Coronary artery aneurysm. Literature review and cases report in Venezuela

“…Proper sizing of the CAA is key to reducing the risk of stent thrombosis and migration (30) but partially thrombosed CAA can result in underestimation of the true size and true extension of the aneurysm, making an accurate assessment of the stent's landing zone difficult. In long aneurysmal segments, several overlapping stents are often needed to cover the full length of the aneurysm (9,31,32).…”

Percutaneous Treatment of Long Coronary Aneurysms

“…Patients with longer aneurysmal segments have been difficult to treat reliably using covered stents. Although multiple overlapping covered stent use has been reported in 2 patients in the literature ( 3 , 4 ), these stents are less trackable compared with conventional stents, and hence the probability of the inability to cross the free-hanging proximal end of the first deployed covered stent with the second covered stents to create the necessary overlap and proper sealing needs to be considered, and the uncertainty may make the interventional operator and the patient reconsider percutaneous options for treatment of longer aneurysmal segments.…”
