Splenic Arteriogastric Fistula Resulting from Adrenocortical Carcinoma: A Rare Cause of Massive Upper Gastrointestinal Hemorrhage  [PDF]
Elias J. Dayoub, Kyung J. Cho
Open Journal of Radiology (OJRad) , 2013, DOI: 10.4236/ojrad.2013.34027
Abstract:

Splenic arteriogastric fistula is a rare cause of upper gastrointestinal (GI) hemorrhage, only reported a handful of times in the literature. Herein, we present a case of a 49-year-old woman with metastatic adrenocortical carcincoma who developed a fistula between the splenic artery and gastric lumen as a result of local invasion of her primary tumor. This fistula led to several episodes of massive upper GI bleeding. Selective splenic artery embolization was successful in ceasing the GI bleed; however, the intervention was not timely enough for the patient to survive the hemorrhage. We outline several clinical and imaging findings to assist physicians with earlier detection of splenic arteriogastric fistulas, and advocate prophylactic selective splenic artery embolization when this rare but highly fatal entity is discovered.

Abstract: the spleen is located in the abdomen, it accomplishes several functions as lymphoid cells generation, hemoglobin and iron metabolism, etc. it is deeply affected in abdominal injuries, that could lead to splenectomies. in this order it is vital an appropriate knowledge of the blood supply to this organ. in these way 51 splenic arteries belonging to venezuelan human fetuses were observed; the gestational ages were from 20 to 40 weeks, they were previously 10 % paraformaldehyde fixed, and afterwards they were red vinyl perfused. after a careful observation of the sample we found: in 78.43 splenic artery gives off 2 terminal braches (superior and inferior), in 21.57 % the artery gives origin to three terminal branches (superior, intermediate and inferior). polaris superior artery was present in 33.33 % of the sample. gastroepiploic artery was seen arising from inferior splenic branch in 82.35 % of the sample, and in 5.88 % taking origin from superior splenic branch, also it was present in 72.55 % of the serie.

Abstract: splenic artery aneurysm was first described by beaussier in 1770, and the first successful treatment was reported by mcleod in 1940. the splenic artery aneurysm is considered the most common splanchnic site for aneurysm formation, affecting 46 to 60% of patients with visceral aneurysms. most patients are asymptomatic, and splenic artery aneurysm is often found during imaging investigation of other abdominal diseases. we describe an unusual case of a 31-year-old female patient with a large splenic artery aneurysm originating from the superior mesenteric artery.

Abstract: among arterial aneurysms, splenic artery aneurysms are very uncommon in the current practice. the etiologic factors are in relation with: angiodisplasia, portal hypertension, pregnancy and atherosclerosis. the great majority are asymptomatic. symptomatic cases are in relation with rupture in the peritoneum or in organs or structures of the vecinity. we present two cases of splenic artery aneurysm in a 57 year old man and in a 59 year old woman. in both cases the diagnosis was made by plain abdominal x-ray, abdominal scanner and abdominal aortography. both cases were surgically treated by transverse laparotomy and total aneurysm resection. the pathology dictamen of the two cases was consistent with atherosclerosis. after 120 and 38 months of follow-up both patients are doing well and without evidence of splenic artery aneurysm. a review of this entity is exposed, with special reference in the etiology, symptomatology, diagnosis and treatment.

Abstract: background: to evaluate the limits, type and independence of splenic artery segmentation. method: we studied 100 not fixed spleens not fixed through the technique of resin (vinyl acetate) injection and corrosion. result: there was segmental independence in 98% of the cases. the type of boundary between adjacent segments was regular on both sides in 52% of cases, irregular on both sides in 27% of cases, and regular on one side and irregular on the other in 21% of the cases. the type of segmental arrangement was similar on both sides of the spleen in 78% of cases. conclusion: we conclude that the arterial segments are independent of the spleen in 98% of cases.

Abstract: splenic artery aneurysm is a rare disease whose incidence varies from 1.6% in autopsies of the general population to 7.1% in autopsies of people suffering from portal hypertension.1 it was first describt by beussier 9 in 1770. in most cases the aneurysms are detected as occasional finds during clinical investigation of other diseases.2 lt is being diagnosed more frequently nowadays because of the increasing use of duplex scan, computorized tomografy and visceral arteriography.11 ln opposition to the aneurysms of great vessels, which are more frequent in men, aneurysms of the splenic artery is more frequent in women.3 this study investigates ten patients with aneurysms of the splenic artery, treated in the universitary hospital clementino fraga filho between 1978 and 1997. the diagnosis was made by arteriography in four patients, by tomography in two, by ultrasound in two. one aneurysm was diagnosed by simple abdominal x-ray and one could only be found during the surgical procedure, as it was ruptured. there was a total of 14 aneurysms, unique in nine patients and multiple (five) in one. we found a predominance of women in a rate of four women to each man. surgical treatment was made in 60% of the patients, embolization with gianturco coills and gellfoan in 10%, association of embolization and surgery in 10% and clinical treatment in 20%. there was no death during treatment.

Abstract: Although the third most frequent aneurysm in the abdomen, after aneurysms of the aorta and iliac arteries, and most frequent aneurisms of visceral arteries, splenic artery aneurysms are rare, but not very rare. Thanks to the new imaging techniques, first of all ultrasonography, they have been discovered with increasing frequency. We present a series of 9 splenic artery aneurysms. Seven patients were female and two male of average age 49 years (ranging from 28 to 75 years). The majority of affected women were multiparae, with average 3 children (ranging from 1 to 6). One patient had a subacute rupture, and 2 had ruptures into the splenic vein causing portal hypertension. The spleen was enlarged in 7 out of 9 patients. The average size of aneurysms was 3,2 cm (ranging from 2 to 8 cm). The preoperative diagnosis of splenic artery aneurysm was established in 6 patients while in 3 patients aneurism was accidentally found during other operations, during splenectomy in 2, and during the excision of a retroperitoneal tumor in 1 patient. Aneurysmectomy was carried out in 7 patients, while a ligation of the incoming and out coming wessels was performed in 2 patients with arteriovenous fistula. Splenectomy was performed in 6 patients, while pancreatic tail resection, cholecystectomy and excision of the retroperitoneal tumor were performed in 3 patients. Additional resection of the abdominal aortic aneurysm with reconstruction of aortoiliac segment was performed in 2 patients. There were no mortality and the postoperative recovery was uneventful in all patients.

Abstract: background and objective: the close anatomic relationship of the pancreas with the splenic vessels and the spleen is responsible for splenic complications in the course of acute pancreatitis. our objective was to report two cases of severe acute pancreatitis complicated by splenic infarction. patients: in a three-month period of time two patients were diagnosed with splenic infarction secondary to acute pancreatitis. in both cases splenic infarction diagnosis and follow-up were carried out using computed tomography. results: in the first case images clearly showed a narrowing of the splenic artery due to the inflammatory pancreatic condition. in the second case no involvement of the splenic vessels could be demonstrated, hence the only possible etiological explanation was a hypercoagulability state generated by pancreatitis. conclusions: it would be advisable that splenic complications were added to the list of relevant extrapancreatic manifestations. ct is very useful for the diagnosis and follow-up of splenic complications arising in acute pancreatitis.
