Endovascular Stent Graft for Treatment of Complicated Spontaneous Dissection of Celiac Artery: Report of Two Cases

We report 2 cases of complicated spontaneous dissection of the celiac artery, which were successfully treated by a stent graft. The first patient was a 47-year-old man who presented with acute abdominal pain. CT scan showed ruptured saccular aneurysm with surrounding retroperitoneal hematoma. The second patient was a 57-year-old man with progressive dissecting aneurysm. Endovascular stent graft was placed in the celiac trunk to control bleeding, and to prevent rupture in each patient. Follow-up CT scans showed complete obliteration of a dissecting aneurysm.

Hipertensión arterial y soplo abdominal / Abdominal bruit associaated to hypertension

La primera causa de hipertensión secundaria es la hipertensión vasculorrenal y suele presentar un soplo abdominal en un 16 a 20% de los casos. Dicho signo clínico también puede acompañar otros procesos vasculares abdominales como la estenosis del tronco celíaco y/o aneurismas localizados a nivel de las arcadas pancreático-duodenales y gastroduodenales, que representan una entidad poco frecuente entre los aneurismas digestivos. Suelen presentarse en el contexto de complicaciones digestivas, como neoplasias, pancreatititis crónica u obstrucciones gástricas, pudiendo cursar clínicamente con ictericia obstructiva, hemorragias y episodios de abdomen agudo. Su presentación en otros contextos representa una rareza y un verdadero reto diagnóstico. El diagnóstico se realiza a través de la arteriografía abdominal que representa la mejor exploración al permitir tanto la localización topográfica como la intervención terapéutica mediante la embolización aneurismática. Especial énfasis merece la celeridad diagnóstica de este tipo de lesiones debido del riesgo intrínseco de ruptura y elevada morbi-mortalidad asociada, si ello ocurre (AU)

First cause of secondary hypertension is renovascular hypertension wich presents abdominal bruit in 16 to 20% of cases. This clinical sign is also associated to other vascular disease of the abdomen such as celiac trunk stenosis and/or aneurysms located on the pancreaticoduodenal or gastroduodenal arcs level, with little representation among aneurysm. They usually appear on a context of digestive complications like neoplasias, cronic pancreatitis or gastric obstruccions possibly with obstructive icterice, hemorrage and acute abdomen episodes. Its presentation in other contexts is rare and constitutes a diagnostic challenge. Diagnostic is made by abdominal artereography wich is the best one as you can locate the problem as well as intervene terapeutically with embolization of the aneurysme. We would like to emphasys on the importance of a quick diagnostic due to the risk of breack and the high morbi-mortality associated (AU)
