Shock hipovolémico por fístula aortoentérica: una causa inusual de hemorragia digestiva

Primary Aorto-duodenal Fistula: A Rare but Potentially Fatal Cause of Gastrointestinal Bleeding

“…It has a diagnostic sensitivity of 40%-90% and specificity of 33%-100%. 8,9 The most frequent findings are bubbles observed around the aorta, lack of a fat plane between the aorta and digestive tract, edema of the intestinal wall around the aorta, and extravasation of contrast medium from the aorta to the intestinal lumen (Fig. 2).…”

“…Angiography has a limited ability to demonstrate fistulae (30%) because it requires losses of more than 0.5 ml/ min to be able to visualize the lesion. 8 It should be reserved for patients who are stable or patients with no underlying aneurysmatic disease in order to plan the type of surgery or percutaneous embolization. 5 Gastroscopy is the method of choice for the initial assessment of patients with UGI hemorrhage.…”

Mycotic aneurysm with aortoduodenal fistula

“…The clinical features of ADF are: (i) gastrointestinal bleeding (64%); (ii) abdominal pain (32%); and (iii) the presence of a pulsatile mass (25%) 31 - 33. Generally, the patients present self-limited gastrointestinal bleeding (sentinel bleeding) followed by massive bleeding.…”

“…Generally, the patients present self-limited gastrointestinal bleeding (sentinel bleeding) followed by massive bleeding. The principal diagnostic examination is the angiogram CT that presents sensitivity ranging from 40% to 90% and specificity from 33% to 100% 33 , 34. However, given the frequent sudden onset of the digestive hemorrhage, imaging exams and an endoscopic examination are not always feasible.…”

Fístula aortoduodenal primaria: una causa rara y potencialmente fatal de hemorragia digestiva

“…La angio-TC constituye el principal mé todo diagnó stico, con una sensibilidad diagnó stica del 40-90% y una especificidad del 33-100% 8,9 . Los hallazgos má s frecuentes son la presencia de burbujas alrededor de la aorta, pé rdida de plano graso entre la aorta y el tracto digestivo, edema de la pared del intestino alrededor de la aorta, y extravasació n de contraste de la aorta a la luz intestinal ( fig.…”
