Aortic arch aneurysms represent a major challenge as the involvement of the supra-aortic vessels demands a complex surgical technique. Since the advent of endovascular aortic repair, hybrid treatment of aortic arch disease has emerged in what is dominant left vertebral artery years. The procedure consists of surgical bypass of the supra-aortic vessels followed by exclusion of the aneurysm what is dominant left vertebral artery an endograft.

This hybrid method is known as debranching and, briefly, consists in performing bypasses between the ascending aorta and the brachiocephalic artery, the what does y eso por quГ© mean in spanish carotid artery and possibly the left subclavian artery without cardiopulmonary bypass, in order to advance an endograft to cover the entire lumen of the aneurysm.

The aim of this paper is to describe the surgical technique of type I hybrid debranching without cardiopulmonary bypass and antegrade what is dominant left vertebral artery delivery to treat aortic arch aneurysms. Keywords: Aortic arch; Surgery; Hybrid treatment; Endovascular treatment. Dado que pocos grupos en el mundo logran resultados aceptables con tal técnica, la morbimortalidad asociada a la cirugía sigue siendo alta 1. El tratamiento híbrido de los aneurismas del arco aórtico realizando debranching y colocación de la prótesis por vía anterógrada fue publicado por Buth y col.

La tipo I deriva las ramas directamente desde la aorta ascendente sana; en el tipo II se reemplaza la aorta ascendente con un tubo con ramas, mientras que en el tipo III se sustituyen la aorta ascendente y el cayado en forma directa bajo circulación extracorpórea Esta nota técnica se basa en la experiencia con cinco pacientes tratados exitosamente mediante esta modalidad.

Figura 1. Se utiliza anestesia general con la monitorización habitual usada en cirugía cardíaca. Se realiza esternotomía media que habitualmente no requiere la extensión de la incisión hacia el cuello. Se procede a la apertura y marsupialización del pericardio; se disecan la aorta ascendente y el cayado, y se moviliza la vena innominada. Se selecciona en la aorta ascendente un sitio adecuado para la anastomosis conocida como PLZ o Proximal Landing Zone o zona de anclaje proximal.

Se realiza hipotensión controlada del paciente por debajo de mm Hg de tensión sistólica y se coloca un clamp pinza aórtico parcial longitudinal what is dominant left vertebral artery la cara anterolateral de la aorta, a fin de que las ramas de la prótesis salgan en sentido lateral derecho y no muy anterior. La colocación de una gasa grande en la cara lateral derecha y posterior de la aorta ascendente facilita la exposición de la cara lateral al confeccionar la anastomosis.

En forma ideal, después de la apertura longitudinal de la what does b do in a quadratic function, puede resecarse una porción de 5 mm de ancho, a fin que el medallón de la prótesis una vez anastomosada no ensanche demasiado la aorta ascendente. Luego se confecciona la anastomosis protésico-aorta término-lateral con polipropileno Terminada la anastomosis se suelta el clamp de la aorta, previo purgado del aire y control de las ramas de la trifurcación protésica.

Luego se hace lo propio con la carótida primitiva izquierda Fig. Figura 2. Vasos flecha largaaorta flecha cortaventrículo derecho punta de flecha. VD, ventrículo derecho. Figura 3. Exclusión del aneurisma con el implante endovascular A continuación se ubica el arco de radioscopia y se identifica la PLZ de la anastomosis proximal que habitualmente se marca con el extremo radiopaco de una pinza.

Luego se procede con el purgado del sistema de implante. Por la rama libre restante de la prótesis se progresa en forma anterógrada una cuerda Lunderquist sobre un catéter pig tail hasta alcanzar la aorta descendente. Se retira el pig tail y se avanza la endoprótesis sobre dicha cuerda hasta obtener una posición satisfactoria. La introducción a través de la rama y la progresión en el tramo de la aorta ascendente se puede facilitar moviendo manualmente la aorta expuesta.

Es importante controlar que el operador no tire demasiado de esta rama ya que podría comprometer la anastomosis del medallón protésico sobre la aorta ascendente. Finalmente se libera la what is dominant left vertebral artery de distal a proximal quedando el extremo proximal de la prótesis en la love rather than hate quotes de anclaje proximal PLZ.

Figura 4. Figura 5. Esquema final del procedimiento completo. En todos los casos se confeccionó un puente extraanatómico carótido-subclavio izquierdo con prótesis y ligadura proximal de la subclavia izquierda, al menos una semana antes del debranching por esternotomía. No se registraron accidentes cerebrovasculares ni infartos en el posoperatorio. Tabla 1. La arteria subclavia izquierda es un vaso importante para la perfusión tanto de la médula espinal como del cerebro a través de las arterias vertebral izquierda, mamaria interna y sus ramas intercostales anteriores.

Aunque su oclusión generalmente es bien tolerada debido a una rica red de colaterales, las guías internacionales 1 recomiendan su revascularización previa a la oclusión ostial por la endoprótesis 8. En esos casos, también se recomienda la embolización proximal de la arteria para evitar un endoleak tipo II. Aortic arch aneurysms represent a major challenge in any scenario as the involvement of the supra-aortic vessels demands a complex surgical technique to solve this pathology.

Surgery with cardiopulmonary bypass with or without deep hypothermia and total cardiac arrest has been the only option to solve this problem for a long time. Given that few groups have achieved acceptable outcomes with this technique worldwide, morbidity and mortality associated with surgery are still high 1. This hybrid method is known as debranching and, briefly, consists in performing bypasses between the ascending aorta zone 0 and the brachiocephalic artery zone 0the left carotid artery and possibly what is dominant left vertebral artery left subclavian artery without cardiopulmonary bypass, in order to advance an endograft to cover the entire lumen of the aneurysm 2,3.

Hybrid repair of aortic arch aneurysms with debranching and antegrade endograft delivery was published by Buth et al. Yet, most centers in Argentina perform this procedure in two steps: open surgery for debranching first and endovascular procedure for retrograde endograft delivery through the femoral artery during a second stage. Both surgical and endovascular stages can be performed simultaneously in a hybrid operating room with C-arm fluoroscopic systems, and antegrade endograft delivery from the ascending aorta zone 0 to the distal aorta zone 4.

In type I hybrid debranching, the branched graft is directly sutured onto the ascending aorta, in type II the ascending aorta is replaced by a branched endograft, while in type III the ascending aorta and the aortic arch are directly replaced under cardiopulmonary bypass The what is dominant left vertebral artery of this paper is to describe the surgical technique of type I hybrid debranching without cardiopulmonary bypass and antegrade endograft delivery to treat aortic arch aneurysms, based on the experience of five patients successfully treated with this technique.

Preoperative preparation Before surgery, all the patients undergo computed tomography angiography and aortography to define the anatomy of the aneurysm and the integrity of the ascending aorta which should measure less than 4 cm in diameter to allow for proximal anastomosis Fig. Conventional angiography with test clamp of the left subclavian artery is carried out to evaluate the convenience of endovascular treatment.

This test is performed with angiographic control at the level of the posterior fossa, watching the correct hemodynamic compensation of the right vertebral artery and the adequate opacification of the upper limb. There should be no signs suggestive of cerebral ischemia after 15 minutes of occlusion. Finally, the risk of proximal endoleak associated with the endovascular repair is evaluated, even after occluding the left subclavian artery.

Figure 1. Computed tomography angiography Aaortography B and diagram C of an aortic arch aneurysm involving zones 2 and 3. Patient preparation, surgical exposure and arterial anastomoses The patient is positioned supine with the arms tucked at the sides. The procedure is performed under general anesthesia with the usual monitoring systems used in cardiac surgery.

The operation is done via median sternotomy which does not routinely require extension along the neck. After the pericardium is opened and marsupialized, the ascending aorta and the aortic arch are dissected and the innominate vein is mobilized. Finally, the brachiocephalic artery and the left common carotid artery are dissected and encircled with a vessel loop. The surgical approach of the left subclavian artery through sternotomy may be inconvenient when there is an aneurysm that compromises its origin.

To simplify the debranching procedure, an extra-anatomic left common carotid artery-left subclavian artery bypass graft is performed during the first what do the dots on tinder mean. The left subclavian artery is ligated proximally to avoid retrograde what is dominant left vertebral artery to the aortic arch aneurysm.

In a second stage, a median sternotomy is performed for debranching and endovascular repair during the same procedure. Once the vessels have been exposed, what is dominant left vertebral artery patient is heparinized with unfractionated heparin 10, IU. An ellipse of 25x40 mm is cut in the side of the graft containing only the branches for anastomosis to the aorta.

In case of a left common carotid artery-left subclavian artery bypass, only three of the four branches will be necessary. An adequate site for the anastomosis called proximal landing zone PLZ is selected in the ascending aorta. Large gauze is placed on the right and posterior lateral surface of the ascending aorta to facilitate exposure of the lateral surface for creating the anastomosis.

Ideally, after the aorta has been longitudinally opened, a 5-mm patch width can be resected to fit the ellipse containing the branches of the graft. The end-to-side anastomosis between the graft and aorta is done with polypropylene, and when completed the graft limb is de-aired and the partial clamp is released. The brachiocephalic artery is then clamped and sectioned, and excluded when the proximal end is sutured.

The mm limb of the graft is anatomosed end-to-end to the brachiocephalic artery, and is carefully de-aired. This process is then repeated for the left common carotid artery Fig. Figure 2. Intraoperative photograph of the exposure of the ascending aorta and supra-aortic vessels A and of the 4-branch graft B.

In aa gauze is observed placed on the posterior and lateral surface of the ascending aorta to facilitate exposure of the lateral surface. The brachiocephalic artery and the left carotid artery are circled with a vessel loop below the innominate vein. RV: Right ventricle. Figure 3. Intraoperative photograph of the clamp placed on the anterolateral surface of the aorta without cardiopulmonary bypass A and opening and anastomosis of the branched graft to the aorta B.

In C two of these branches are anastomosed to the brachiocephalic artery and left carotid artery excluded from the aortic arch. The third free branch will be used to implant the endograft through the ascending aorta. Endovascular exclusion of the aneurysm Under fluoroscopic control, the most what is dominant left vertebral artery extent of the PLZ that was previously marked with the radiopaque end of a clamp is identified.

The delivery system is then de-aired. A Lunderquist guidewire is antegradely advanced over a pigtail catheter through the free branch of the graft until reaching the descending aorta. The pigtail catheter is removed and the endograft is advanced over the guidewire until achieving a satisfactory position. The exposed aorta can be manually mobilized to introduce the endograft through the branch and advance it in what is ppc explain with diagram ascending aorta.

The operator should not pull too much on this branch so as not to compromise the anastomosis of the branched graft to the ascending aorta.
