ABSTRACT

Abstract Stent-graft migration and type I endoleaks are associated with a higher rate of reintervention and increased mortality and morbidity. This article describes a patient presented with an infrarenal aortic stent-graft which had migrated into the aortic sac with loss of all aortic neck attachment. The acutely expanding abdominal aortic aneurysm was treated by placing a second modular endograft within and above the migrated stentgraft. The patient returned 36 months later, with features of an acute myocardial infarction, severe bilateral lower limb ischemia, and renal failure. He was too ill for intervention and demised within 48 hours.

ABSTRACT

Abstract We describe the treatment of a patient presenting with very-late stent thrombosis with the use of a drug-coated balloon. In this patient, optical coherence tomography disclosed that ruptured and complicated neoatherosclerosis was the underlying substrate responsible for the episode of very-late stent thrombosis. The potential use of drug-coated balloons in this unique scenario is discussed.


Resumo Descrevemos o tratamento de um paciente apresentando trombose de stent muito tardia com a utilização de um balão farmacológico. Nesse paciente, a tomografia de coerência ótica revelou que a neoaterosclerose apresentava-se complicada e com ruptura, sendo portanto o substrato subjacente responsável pelo episódio de trombose de stent muito tardia. O uso potencial de balões farmacológicos nesse cenário especial é discutido.

ABSTRACT

Mais informações são necessárias para definir se o tratamento percutâneo da coartação da aorta com stents é superior à angioplastia com cateter-balão. De julho de 2000 a maio de 2003, 21 adolescentes e adultos com coartação da aorta focal e média de idade de 24 anos (DP 11 anos) foram submetidos, consecutivamente, a implante de stents (grupo 1). Os resultados foram comparados com os obtidos em um grupo histórico de 15 pacientes com média de idade de 18 anos (DP 10 anos) (p = 0,103) submetidos a angioplastia (grupo 2) nos últimos 18 anos. Após o procedimento, a redução do gradiente sistólico foi maior (99% [DP 2%] versus 87% [DP 17%]; p = 0,015), o gradiente residual foi menor (0,4 mmHg [DP 1,4 mmHg] versus 5,9 mmHg [DP 7,9 mmHg]; p = 0,019), o ganho no local da coartação foi maior (333% [DP 172%] "versus" 190% [DP 104%]; p = 0,007) e o diâmetro da coartação foi maior (16,9 mm [DP 2,9 mm] versus 12,9 mm [DP 3,2 mm]; p < 0,001) no grupo 1. Alterações da parede da aorta, incluindo dissecções, abaulamentos e aneurismas, foram observadas em oito pacientes do grupo 2 (53%) e em um do grupo 1 (7%) (p < 0,001). Não houve complicações maiores. Cateterismo (n = 33) ou ressonância magnética (n = 2) de controle foram realizados em seguimento mediano de um ano para o grupo 1 e um ano e meio para o grupo 2 (p = 0,005). A redução do gradiente sistólico persistiu em ambos os grupos; entretanto, gradientes tardios mais altos foram observados no grupo 2 (mediana de 0 mmHg para o grupo 1 versus 3 mmHg para o grupo 2; p = 0,014). Não houve perdas no diâmetro da coartação no grupo 1 e houve ganho tardio no grupo 2 (16,7 mm [DP 2,9 mm] versus 14,6 mm [DP 3,9 mm]; p = 0,075). No grupo 1, dois pacientes necessitaram de novo implante de stent em decorrência da formação de aneurisma ou fratura da malha do stent. No grupo 2, as anormalidades da parede aórtica não progrediram e um paciente necessitou de redilatação em decorrência da recoartação. A pressão arterial sistêmica...


More information is needed to define whether stenting is superior to balloon angioplasty for coarctation of the aorta. From July/2000 to May/2003, 21 adolescents and adults with discrete coarctation underwent consecutive stent implantation at a mean age of 24 years (SD 11 years) (group 1). The results were compared to those achieved by balloon angioplasty performed in the last 18 years in a historical group of 15 patients at a mean age of 18 years (SD 10 years) (p = 0.103) (group 2). After the procedure, systolic gradient reduction was higher (99% [SD 2%] vs. 87% [SD 17%]; p = 0.015), residual gradients lower (0.4 mmHg [SD 1.4 mmHg] vs. 5.9 mmHg [SD 7.9 mmHg); p = 0.019), gain at the coarctation site higher (333% [SD 172%] vs. 190% [SD 104%]; p = 0.007) and coarctation diameter larger (16.9 mm [SD 2.9 mm] vs.12.9 mm [SD 3.2 mm]; p < 0.001) in group 1. Aortic wall abnormalities, including dissections, bulges and aneurysms, were observed in eight patients in group 2 (53%) and in one in group 1 (7%) (p < 0.001). There was no major complication. Repeat catheterization (n = 33) or magnetic resonance imaging (n = 2) was performed at a median follow-up of 1.0 year for group 1 and 1.5 year for group 2 (p = 0.005). Gradient reduction persisted in both groups, although higher late gradients were observed in group 2 (median of 0 mmHg for group 1 vs. 3 mmHg for group 2; p = 0.014). There was no late loss in the coarctation diameter in group 1 and there was a late gain in group 2 (16.7 mm [SD 2.9 mm] for group 1 vs. 14.6 mm [SD 3.9 mm] for group 2; p = 0.075). Two patients required late stenting due to aneurysm formation or stent fracture in group 1. Aortic wall abnormalities did not progress and one patient required redilation due to recoarctation in group 2. Blood pressure was similar in both groups at follow-up (systolic: 126 mmHg [SD 12 mmHg] in group 1 vs. 120 mmHg [SD 15 mmHg] in group 2; diastolic: 81 mmHg...
