“…T rue visceral artery aneurysms are a rare and uncommon form of vascular disease often found incidentally in 0.09% to 2% of the general population (1)(2)(3). However, these true aneurysms have an incidence of rupture and mortality rate of 20% to 75% due to life-threatening hemorrhage (4,5).…”

ORIGINAL ARTICLE PURPOSE We aimed to evaluate the outcomes of coil embolization of true visceral artery aneurysms by three-dimensional contrast-enhanced magnetic resonance (MR) angiography. MATERIALS AND METHODSWe used three-dimensional contrast-enhanced MR angiography, which included source images, to evaluate 23 patients (mean age, 60 years; range, 28-83 years) with true visceral artery aneurysms (splenic, n=15; hepatic, n=2; gastroduodenal, n=2; celiac, n=2; pancreaticoduodenal, n=1; gastroepiploic, n=1) who underwent coil embolization. Angiographic aneurysmal occlusion was revealed in all cases. Follow-up MR angiography was conducted with either a 1.5 or 3 Tesla system 3-25 months (mean, 18 months) after embolization. MR angiography was evaluated for aneurysmal occlusion, hemodynamic status, and complications. RESULTSComplete aneurysmal occlusion was determined in 22 patients (96%) on follow-up MR angiography (mean follow-up period, 18 months). Neck recanalization, which was observed at nine and 20 months after embolization, was confirmed in one of eight patients (13%) using a neck preservation technique. In this patient, a small neck recanalization covered by a coil mass was demonstrated. The complete hemodynamic status after embolization was determined in 21 patients (91%); the visualization of several collateral vessels, such as short gastric arteries, after parent artery occlusion was poor compared with that seen on digital subtraction angiography in the remaining two patients (9%). An asymptomatic localized splenic infarction was confirmed in one patient (4%). CONCLUSIONOur study presents the follow-up results from three-dimensional contrast-enhanced MR angiography, which confirmed neck recanalization, the approximate hemodynamic status, and complications. This effective and less invasive method may be suitable for serial follow-up after coil embolization of true visceral aneurysms.

“…Visceral arterial aneurysms remain rare cases, with a reported incidence of 0.1-0.2% in autopsy studies (11)(12)(13). This pathology usually occurs during the fifth and the sixth decade of life and induces unspecific symptoms, such as diffuse abdominal pain, jaundice or portal hypertension depending on the location of the aneurysm (14)(15)(16)(17).…”

Abstract.Hepatic artery aneurysms account for up to 20% of all reported visceral aneurysms and might remain asymptomatic for a long period of time (1, 2). In cases presenting large lesions, compression on the elements of the hepatic pedicle might be encountered, inducing portal hypertension. It is estimated that the risk of aneurysmal rupture ranges between 20% and 80%, and the mortality rate reaches up to 21% (3, 4). Due to this reason, and the fact that there is no strong evidence to demonstrate any correlation between aneurysm size and rupture risk, all hepatic aneurysms should be treated (5). The main therapeutic procedures in uncomplicated aneurysms include endovascular techniques, such as percutaneous embolization or classical surgical approach, consisting of aneurysmal resection with or without vascular reconstruction. On the other hand, reconstructive procedures are mainly indicated when a patent collateral vascularization is not present (6). Case ReportA 68-year-old patient, who was investigated for recurrent upper digestive tract bleeding, was diagnosed during a computed tomography examination with a large aneurysm affecting the common and the proper hepatic artery as well as the gastroduodenal artery, and compressing the portal vein. The imagistic examinations revealed the presence of an accessory left hepatic artery entering the left liver lobe, originating from the left gastric artery. Due to the presence of the large, partially thrombosed aneurysm involving the common and the proper hepatic artery, as well as the gastroduodenal artery, the patient was initially submitted to a percutaneous right portal branch embolization in order to induce a left hemiliver hypertrophy. Two months later the patient was submitted to surgery; intraoperatively the findings of the imagistic examinations were confirmed. The 979

Upon determining an intrauterine dead fetus in the epicenter of the 24-week pregnant patient aged 25 years, the epicrisis/ discharge report of the patient revealed that she had been referred to the emergency service. The patient was also determined to have been suffering from diabetes mellitus. When this patient was evaluated in the emergency department, it was seen that she had bradycardic and a filiform pulse with TA: 30/20 mmHg, that there was no finding with respect to any trauma dur-ABSTRACT Introduction: Splenic artery aneurysm (SAA) is a rarely seen disease but with a high probability of rupture in pregnancy cases. Once a rupture occurs, both the mother's and the fetus's lives are at risk. It is rather difficult to establish a diagnosis under emergency conditions because it may be confused with obstetric pathologies. Case Report: A 25-year-old, 24-week pregnant patient was admitted to the emergency department with an arterial blood pressure of 30/20 mmHg, a filiform pulse, and with no sign of trauma upon physical examination. An ultrasonography scan revealed pregnancy with negative fetal heart beats (FHA). The hemoglobin of the patient was 4.2 g/dL. The patient had undergone explorative laparotomy, with the preliminary diagnosis of intrauterine dead fetus. The patient was diagnosed with SAA. Because the patient had diffuse infarction in the spleen and severe bleeding from the uterus, she underwent splenectomy and total abdominal hysterectomy. The patient was discharged with cure on the 5th postoperative day. Conclusion:We aimed to emphasize the fact that a SAA may have developed in pregnant women who apply to the emergency service department with complaints of stomachache and hypotensive findings without a medical record involving any trauma and that taking rapid action in such cases is something to be kept in mind by physicians.
