Application of fusion imaging in the treatment of complex aortic pathology / 中华胸心血管外科杂志

Objective:To explore the value of fusion imaging in the treatment of complex aortic pathology.Methods:A retrospective analysis was conducted of 29 patients with complex aortic pathology who underwent treatment with endovascular aortic repair using fusion imaging (FI+ ) technique or without FI (FI-) between June 2015 and June 2021. The perioperative outcomes and morbidity of the FI was assessed and the early results of follow up were evaluated.Results:The mean age of patients was (70.3±7.3) years old, and 24 (82.8%) males. Technical success was 96.5% (28/29). The FI+ group patients had lower procedure time[FI+ , (209±53) min vs. FI-, (306±24)min, P=0.005]and ionic contrast medium[(169±23)ml vs. (201±20)ml, P=0.040]. Contrast-induced acute kidney injury (CI-AKI)[3.4%(FI+ 0 vs. FI-6.7%, P=0.33)], and operation-related reintervention[6.9%(FI+ 0 vs. FI-13.3%, P=0.16)] were similar. There were no significant differences in blood loss, fluoroscopy time. Conclusion:FI technique improves the accuracy during positioning in complex endovascular aortic repair, could reduce aortic related reintervention rate, operation time and contrast dose. Further studies and development are needed to obtain optimal image quality and higher precision.

Implantación endovascular urgente de stent en disección aórtica aguda tipo III de DeBakey / Emergency endovascular stent graft implantation for acute traumatic DeBakey type III aortic dissection

RESUMEN El tratamiento de las enfermedades de la aorta torácica con la implantación percutánea de stent se viene realizando desde su aplicación, por primera vez, a principios del siglo XX. Se presenta un paciente de 79 años de edad que fue llevado a urgencias con intenso dolor de espalda posterior a un accidente automovilístico, a quien se le realizó tomografía computarizada y se le diagnosticó una disección aórtica tipo III de DeBakey. Se le implantó un stent endovascular autoexpandible de nitinol (Talent Stent Graft, Medtronic) en la aorta descendente, donde comenzaba el segmento disecado. Este procedimiento es un método eficaz para prevenir la isquemia de órganos y la ruptura vascular en las enfermedades traumáticas de la aorta. Es menos invasivo, tiene menos complicaciones que el tratamiento quirúrgico, y es efectivo para restituir el flujo sanguíneo de forma rápida y segura.

ABSTRACT The applications of thoracic aorta pathologies with a stent graft percutaneously have been performed for the first time since the beginning of the 20th century. Computed tomography was performed on a 79-year-old patient who was brought to the emergency room due to an in-vehicle traffic accident with severe back pain, and DeBakey type III aortic dissection was determined. An endovascular self-expanding nitinol stent (Talent Stent Graft, Medtronic) was implanted in the descending aorta where the dissected segment begins. Stent graft implantation is an effective method in preventing organ ischemia and rupture in traumatic aortic pathologies. This procedure is less invasive and has less complication than surgical approach. It is effective in providing blood flow quickly and safely.

Aorta bivalva: Frecuencia y lesiones asociadas. Estudio prospectivo en 2,750 ecocardiogramas consecutivos / Bicuspid aorta valve: Frequency and associated injuries. Prospective study in 2750 echocardiograms in a row

Objetivo: Evaluar mediante un estudio prospectivo, observacional y transversal, la incidencia de la aorta bivalva y su asociación con patología aórtica en el laboratorio de ecocardiografía. Material y métodos: Se analizaron todos los enfermos consecutivos estudiados mediante ecocardiografía del 1º de septiembre de 2009 al 14 de enero de 2011 en búsqueda de aorta bivalva y su asociación con otra patología aórtica. Resultados: Se realizó un total de 2,750 estudios en este periodo de tiempo. En 72 (2.6%) no fue posible precisar con claridad el número de valvas. Se detectaron 137 enfermos con aorta bivalva (4.9%). El promedio de edad fue 13.3 años ± 9.6, mediana de 11 años, 81 fueron hombres (59.1%) y 56 fueron mujeres (40.9%), 14 (10.2%) tuvieron por lo demás corazón estructuralmente normal. En 99 (72.3%) se encontraron lesiones relacionadas con patología aórtica: 50 (36.5%) fueron coartación aórtica, 22 (16.1%) doble lesión aórtica, 10 (7.3%) estenosis subaórtica, 9 (6.6%) estenosis aórtica, 1 (0.7%) dilatación aneurismática de raíz aórtica con coartación aórtica, 2 (1.5%) con dilatación aórtica no significativa de la raíz aórtica, 3 (2.2%) insuficiencia aórtica, 1 (0.7%) interrupción del arco aórtico, 1 (0.7%) desarrolló endocarditis, y en 24 casos (17.5%) con aorta bivalva se encontraron lesiones no relacionadas con patología aórtica. Conclusiones: La aorta bivalva en un laboratorio de ecocardiografía es relativamente frecuente: 4.9% en este trabajo. En los pacientes con corazón estructuralmente normal se encontró aorta bivalva en el 0.5% de la población. La presencia de aorta bivalva estuvo asociada con lesión significativa en ella misma o con otras lesiones del tracto de salida izquierdo en el 3.6% de los casos. La dilatación aórtica y coartación aórtica estuvieron presentes en un paciente (0.7%). La presencia de endocarditis bacteriana asociada a aorta bivalva la encontramos en el 0.7%. Es importante el seguimiento a largo plazo de aquellos pacientes que presentan aorta bivalva dado que hasta en un 30% de los casos pueden desarrollar complicaciones.

Objective: To evaluate by a prospective, observational and cross study the incidence of bicuspid aorta valve and associated aortic disease in the echocardiography laboratory. Material and methods: We analyzed all the consecutive patients studied by echocardiography from the 1st of September 2009 to January 14, 2011, in search of bicuspid aortic bivalve and its associations. Results: A total of 2,750 studies were made in this period of time. In 72 (2.6%) was not possible to specify clearly the number of valves. There were detected 137 patients with bicuspid aortic (4.9%). The age average was 13.27 years ± 9.64, median 11 years, 81 were men (59.1%), 56 women (40.9%), 14 (10.2%) were otherwise structurally normal heart. It was found that 99 (72.3%) had aortic disease-related injuries: 50 (36.5%) had aortic coarctation, 22 (16.1%) double aortic lesion, 10 (7.3%) subaortic stenosis, 9 (6.6%) aortic stenosis, 1 (0.7%) dilation of aortic root aneurysm with aortic coarctation, 2 (1.5%) no significant expansion of the root aortic, 3 (2.2%) aortic regurgitation, 1 (0.7%) interrupted aortic arch, 1 (0.7%) developed endocarditis a in 24 cases (17.5%) with bicuspid aortic lesions were not related to aortic disease. Conclusions: The bicuspid aorta in an echocardiography lab is relatively frequent: 4.9% in this work. In patients with structurally normal heart bicuspid aorta were found in 0.5% of the population. The presence of bicuspid aorta was associated with significant injury to herself or with other lesions of the left outflow tract in 3.6% of cases. The aortic dilatation and aortic coarctation was present in 0.7% patients. The presence of bacterial endocarditis associated with bicuspid aortic found in 0.7%. It is important to the long-term monitoring of those patients with bicuspid aortic as much as 30% of cases can develop complications.
