Restoration of aortopulmonary shunt patency

Transcatheter stenting of the systemic‐to‐pulmonary artery shunt: A 7‐year experience from a single tertiary center

“…Reported complications during transcatheter stent implantation, include stent malpositioning, stent thrombosis and femoral arterial thromboses . We had no instances of acute stent thrombosis.…”

“…Endovascular stent implantation for treatment of shunt stenosis was described by Hatai in 1995 and Zahn in 1997 . Since that time, there have been case reports and a few small case series describing stent implantation in the various types of SPSs, including classical Blalock‐Taussig shunts, modified Blalock‐Taussig shunts and central aorto‐pulmonary shunts with good results and low morbidity . This report represents the largest series describing the application of transcatheter stent technology in a diverse group of patients with SPS.…”

“…Catheter‐based techniques include thrombolysis, mechanical thrombectomy, balloon angioplasty and stent implantation . Case reports and small case series have been published showing that stent implantation within a SPS can be performed to achieve patency of a shunt . We present our experience of all patients who presented to the cardiac catheterization laboratory from January 2006 to December 2013 and underwent transcatheter stent implantation within a SPS.…”

“Bail-out” stenting for acute obstruction of a modified Blalock-Taussig shunt following selective angiography

“…Emergency placement of a stent for acute obstruction of a Blalock-Tasussig shunt has recently been reported, most commonly because of intraluminal formation of thrombus. 1,2,4,5 We chose to use a Palmaz Corinthian stent, considering it would be easier to navigate this stent around the acute angle at the takeoff of the shunt than would an original Palmaz stent. As the shunt was initially 5 mm in diameter, we did not use a coronary stent.…”

“…[1][2][3][4][5] We here report recanalisation using a stent of acute obstruction in a modified Blalock-Taussig shunt with extremely unusual pathogenesis. …”
