Interventions Involving the Use of Covered Coronary Artery Stents for Pseudoaneurysms of Blalock-Taussig Shunts

Abstract: One of the most rare and dangerous complications of a modified Blalock-Taussig shunt involves the formation of a pseudoaneurysm. A pseudoaneurysm may rupture or may result in other adverse events including compression of mediastinal structures or collapse of the underlying lung parenchyma. Shunt-related pseudoaneurysm may be associated with shunt occlusion, bacteremia, or pulmonary hemorrhage. We describe two cases complicated by large pseudoaneurysm formation, following systemic-to-pulmonary artery shunt oper… Show more

“…In these cases, the transcatheter approach is preferred. Successful placement of covered coronary stents, after coil embolization was described in several cases with complicated large pseudoaneurysm formations ( 86 ). In addition, it has been reported that slow-growing pseudoaneurysm after BTS stent implantation was successfully excluded with a self-expandable stent graft without complication in the immediate and short-term follow-up ( 50 ).…”

“…Other vascular accesses include the brachial and carotid arteries or the femoral vein for control angiography and stent placement especially in small infants ( 29 ). The subclavian and radial arteries were also used for re-opening without complications ( 25 , 68 , 86 ). Some studies reported that the carotid artery may be an alternative access to the femoral artery with a low rate of complications and a higher success rate in relieving shunt obstruction.…”

“…Known complications of the modified BT shunt include excessive shunt flow, thrombosis, and pseudoaneurysm [2]. These complications are often managed by emergent surgical intervention with high rates of mortality and morbidity [3]. Here we report very unusual case of giant pseudoaneurysm which arises from insertion site of the shunt diagnosed by Cardiac CT.…”
