“…El riesgo de ruptura varía de 2-3% en las series más recientes y aumenta con el embarazo, la hipertensión portal, cirrosis hepática y trasplante hepático. 1,2,4 La mayoría de los casos de ruptura son súbitos, causando colapso circulatorio inmediato y 25% de ellos presentará un fenómeno de doble ruptura, que se caracteriza por la contención de la ruptura inicial del aneurisma por el omento o por coágulos que bloquean el hiato de Winslow; esto es seguido por una ruptura hacia la cavidad peritoneal, horas o días después. La segunda ruptura tiene un alto riesgo de mortalidad y se presenta como colapso hemodinámico severo.…”

“…La tomografía permite visualizar la forma y localización del aneurisma esplénico directo, completo y satisfactoriamente, la extensión de la lesión, así como su relación con las estructuras vasculares asociadas. 4,7 Los aneurismas de la arteria esplénica sintomáticos siempre deben ser tratados. Las indicaciones para el tratamiento de un aneurisma esplénico asintomático son diámetro mayor de 2 cm, pseudoaneurismas, hipertensión portal, shunt portocava, fibrodisplasia arterial de la media, arterioesclerosis, aumento progresivo de tamaño, como preparación preoperatoria para trasplante hepático y en pacientes embarazadas o mujeres en edad fértil.…”

Accidente automovilístico con volcadura a los 40 años, sin daño orgánico aparente.…”

El aneurisma de la arteria esplénica es una dilatación anormal mayor de 1 cm de diámetro, es el tercer aneurisma intraabdominal más común y el aneurisma visceral más frecuente. Caso clínico: Femenino de 41 años, posterior a accidente automovilístico presenta dolor progresivo en hipocondrio izquierdo; el ultrasonido reporta aneurisma de arteria esplénica y colelitiasis, la angiotomografía confirma aneurisma de arteria esplénica. Se realiza embolización selectiva y colocación de coils, presentando nuevamente dolor abdominal y leucocitosis, nueva angiotomografía con oclusión de arteria esplénica e infarto esplénico, por lo que ameritó la realización de esplenectomía y colecistectomía abierta. Discusión: El 95% de los aneurismas son asintomáticos, el resto pueden presentar dolor en epigastrio y/o hipocondrio izquierdo. Generalmente, son hallazgos incidentales en radiografías, ultrasonidos o tomografías abdominales. Se debe considerar intervención en ciertos casos, siendo el tratamiento de elección la embolización o aplicación de stent por abordaje endovascular. La cirugía convencional se reserva para aneurismas complicados o en caso de ruptura. Conclusión: Actualmente, el tratamiento de elección de los aneurismas esplénicos es el abordaje endovascular. Se presenta un aneurisma a nivel de hilio esplénico que recibió tratamiento endovascular, el cual condicionó infarto esplénico, por lo que ameritó esplenectomía convencional.

“…Also, splenic artery is the third most common loca-tion of intraabdominal aneurysms, after aneurysms of the abdominal aorta and the iliac arteries, with prevalence from 0.2% to 10.4% (3). They are more common in females with 4:1 predominance (4). The vast majority of the splenic artery aneurysms are discovered incidentally, with more widespread use of advanced imaging.…”

Splenic artery pseudoaneurysm (SAP) is extremely rare, but potentially fatal medical condition. In the literature to date, pseudoaneurysms of the splenic artery were described in less than 250 cases. The most frequent cause of this rare condition is pancreatitis. Patients with splenic artery pseudoaneurysms are almost always presented by severe clinical symptoms. Ruptured pseudoaneurysms can cause fatal complications. The aim of this study was to present radiological possibilities in diagnostics of SAP in a patient suffering from chronic pancreatitis. Patient was initially advised for Ultrasound and Color Dopller sonography where lesion suspicion for SAP was made. Further, CT angiography and DSA were performed to provide certain diagnosis. The patient was surgically treated and histopathological examination definitely confirmed diagnose of SAP.

“…Aberrant splenic artery arising from superior mesenteric artery (SMA), also known as splenomesenteric-trunk, is an anatomical variant seen in less than 1% of population, present more commonly in females 1 ; it’s possible embryological basis being interruption of ventral longitudinal anastomosis. Aneurysms of the aberrant splenic artery are seen in a proximial position near the origin of splenic artery from SMA; compared to common location of splenic artery aneurysms in distal-half of splenic artery in patients with orthotopic splenic arteries.…”

An aberrant splenic artery arising from the superior mesenteric artery, also known as the splenomesenteric trunk, is a rare anatomical variant seen in less than 1% of the population and is more common in females. Aneurysms of the splenic artery originating anomalously from the superior mesenteric artery are extremely rare; only 35 cases of aneurysm of an aberrant splenic artery have been described so far in the English medical literature. We report an extremely rare case of aneurysm of aberrant splenic artery in a 28-year-old man in whom the lesion was detected during routine abdominal scanning and confirmed on computed tomography angiography. Aneurysms of an anomalous splenic artery originating from the superior mesenteric artery are extremely rare; however, they are clinically important because possible rupture could be catastrophic. Exploring these variations is important especially if surgical intervention is contemplated. This could greatly affect the surgical planning and avoid injuries to major arteries and organs intraoperatively. Keywords Aberrant splenic artery, aneurysm, mesenteric arteryAberrant splenic artery arising from superior mesenteric artery (SMA), also known as splenomesenterictrunk, is an anatomical variant seen in less than 1% of population, present more commonly in females 1 ; it's possible embryological basis being interruption of ventral longitudinal anastomosis. Aneurysms of the aberrant splenic artery are seen in a proximial position near the origin of splenic artery from SMA; compared to common location of splenic artery aneurysms in distal-half of splenic artery in patients with orthotopic splenic arteries.2 Proximal anatomical origin coupled with retro-pancreatic location further complicates their management.2,3 Treatment options include surgical resection, laparoscopic techniques and endovascular therapy 4 ; endovascular treatment is safe and minimally invasive with rapid recovery. 3,4A 28-year-old man presented with generalised weakness. Routine ultrasound abdomen revealed anechoic area, in continuation with SMA, showing swirling arterial flow on colour Doppler. Another vessel was arising from this dilatation, coursing towards the spleen. Computed tomography angiography revealed (Figure 1) a 31 Â 27 Â 19 mm saccular aneurysm 18 mm distal to SMA (SMA was normal at its origin). The aneurysm arose off the superior lateral margin of SMA, projecting anterio-laterally, towards right, having a narrow neck which measured 2.4 mm. Enlarged and tortuous splenic artery originated directly from this aneurysm. A hypoplastic celiac artery gave origin to left gastric and common hepatic arteries. Rest of the visceral arteries were normal. There was no history of pancreatitis, trauma or alcohol intake. Considering the large size of the aneurysm, stenting and/or embolisation was advised; however, the patient refused any intervention. He was discharged with the advice of close follow-up.Aneurysms of an aberrant splenic artery are extremely rare, with only 35 such cases been described so far ...
