RESUMO
BACKGROUND: Spontaneous isolated celiac artery dissection (SICAD) is uncommon, with very few series reported in the literature. The present study aims to describe the clinical characteristics and treatment outcomes of patients with SICAD treated at a single Chilean institution over 20 years. METHODS: A retrospective review of all patients from a single academic hospital with SICAD diagnosed between January 2003 and March 2023 was performed. Conservative treatment included antiplatelets, anticoagulation, or both. The normal size of a celiac artery in our population was 7.9 ± 0.79 mm in females and 8.3 ± 1.08 mm in males. We defined a celiac artery with a diameter equal to or more than 12.5 mm as an aneurysmal celiac artery. RESULTS: The cohort included 27 patients; 77.8% (n = 21) were males. The median age was 51.0 years (range: 38-84 years). Fourteen (51.8%) patients presented with aneurysmal dilatation. Fourteen (51.8%) patients were treated with antiplatelets, 6 (22.2%) patients with anticoagulation, and 7 (25.9%) with anticoagulation and antiplatelets. One patient was treated with endovascular therapy due to a pseudoaneurysm of the celiac artery detected 10 days after conservative treatment with antiplatelets. The median length of hospital stay was 5 days (range: 2-14 days). Complete remodeling was seen in 6 (22.2%) patients, partial remodeling in 10 (37.0%) patients, and no change was seen in 8 (26.9%) patients. Three (11.5%) patients were lost to follow-up. There were no significant differences between treatments and remodeling outcomes (P = 0.729). The median celiac artery diameter of patients with aneurysmal dilatation was 13.5 mm (range: 12.5-20.5 mm). Systemic arterial hypertension was found more commonly in patients who presented with aneurysmal dilatation than in patients without (87.5% vs. 12.5%, respectively, P = 0.016). Mean follow-up was 41.5 months and median follow-up was 16 months (range: 6-204 months). CONCLUSIONS: Most patients with SICAD can be treated conservatively with excellent outcomes. Hypertension was more commonly found in patients with SICAD and aneurysmal dilatation.

The middle aortic syndrome (MAS) is an uncommon clinical expression as a result of isolated stenosis or complete occlusion of the descending thoracic and/or abdominal aorta; Takayasu's arteritis (TA) is a rare vasculitis and a recognized etiology of MAS. We herein present the case of a 52-year-old woman with refractory renovascular hypertension and progressive bilateral lower extremity claudication; she had known history of TA. A computed tomography angiography demonstrated an aortic occlusive lesion compromising the origin of the celiac trunk, superior mesenteric, and bilateral renal arteries. The patient underwent a complex aortic reconstruction with visceral and renal vessels revascularization utilizing a back-table hand-crafted 4-branch Dacron graft through a left thoracoabdominal approach. The patient recovered uneventfully and was discharged on postoperative day 5, and at 36 months from her surgery, she remains symptoms-free and without antihypertensive agents.

La colecistectomía laparoscópica es el tratamiento de elección de la colelitiasis; sin embargo, se acompaña de comorbilidades y no está exenta de complicaciones mayores que pueden ser letales; la identificación del trígono cistohepático con disección y ligadura de la arteria cística son pasos obligatorios de la cirugía; la identificación de las variaciones de la arteria cística y los conductos biliares pueden minimizar las eventuales complicaciones. Al protocolo preoperatorio se implementó una angiotomografía con Tomógrafo Siemens Somatón Sensation ® de 64 cortes para identificar la arteria cística en pacientes con colelitiasis de la Unidad de Cirugía General del Hospital de Especialidades Teodoro Maldonado Carbo IESS de Guayaquil. Se escogieron 60 pacientes femeninos en forma aleatoria (edades 19-70 años, promedio 44,25 años) y la muestra se dividió en dos grupos de 30; al grupo estudio se aplicó angiotomografía hasta un mes antes de la cirugía y al grupo control se le aplicó el protocolo convencional. Se evaluó morbilidades relacionadas con: hemorragia operatoria por lesión de la arteria cística y en el posoperatorio: infección de herida operatoria, íleo y drenaje. La angiotomografía permitió identificar la arteria cística en el preoperatorio y contribuyó a disminuir comorbilidades que acompañan a la colecistectomía laparoscópica.
Laparoscopic cholecystectomy is the treatment of cholelithiasis of choice; however, it is accompanied by comorbidities and is not exempt from major complications that can be lethal; the identification of the cystohepatic trigone with dissection and ligation of the cystic artery are mandatory steps of surgery; the identification of the variations of the cystic artery and the bile ducts can minimize the possible complications. The preoperative protocol was implemented with an angiotomography with Siemens Somatón Sensation ® 64-slice Tomograph to identify the cystic artery in patients with cholelithiasis of the General Surgery Unit of the Teodoro Maldonado Carbo IESS Specialty Hospital of Guayaquil. 60 female patients were chosen at random (ages 19 -70 years, average 44.25 years) and the sample was divided into two groups of 30; Angiotomography was applied to the study group up to one month before surgery and the conventional protocol was applied to the control group. Morbidities related to: operative haemorrhage due to cystic artery and postoperative injury: operative wound infection, ileus and drainage were evaluated. Angiotomography allowed to identify the cystic artery in the preoperative period and contributed to decrease comorbidities that accompany laparoscopic cholecystectomy.

Takayasu arteritis is an idiopathic and chronic granulomatous vasculitis manifested in the form of panaortitis, of unknown etiology, even though an autoimmune origin is postulated. It is progressive and generates, in adults and children, segmental stenosis, occlusion, dilation and / or aneurysms. Isolated gastrointestinal vasculitis without systemic involvement is rare. This case leads us to take into account the atypical abdominal manifestation of Takayasu arteritis in the differential diagnosis of a frequent symptom, such as epigastralgia, and to highlight the role currently played by non-invasive imaging methods for its diagnosis.
La arteritis de Takayasu es una vasculitis idiopática y granulomatosa crónica que se manifiesta en forma de panaortitis, de etiología desconocida, aunque se postula un origen autoinmune. Es progresiva y genera, tanto en adultos como en niños, estenosis segmentaria, oclusión, dilatación y/o aneurismas. La vasculitis aislada gastrointestinal sin afectación sistémica es rara. Este caso lleva a tener en cuenta la manifestación abdominal atípica de la arteritis de Takayasu en el diagnóstico diferencial de un síntoma frecuente, como la epigastralgia, y a destacar el rol que ocupan en la actualidad los métodos de imágenes no invasivos para su diagnóstico.

Background: Spontaneous dissections of visceral arteries are rare and usually secondary to other disease. There is paucity of information about their natural course. Aim: To describe the imaging, clinical characteristics and follow-up of spontaneous visceral artery dissections diagnosed at our institution. Material and Methods: We report a series of 14 patients in whom a spontaneous dissection of a visceral artery was diagnosed on abdominal angio-CT between 2010 and 2018. Clinical features and evolution were recorded. Results: Isolated lesions of the celiac axis were the most common finding. Multiple territories were involved in 14% of cases. A dissection flap was observed in four cases, a hematoma-dissection complex in seven and an aneurysmal dilatation associated with the dissection in three. Of the 10 patients who were followed at our institution, 90% had stabilization or partial regression of the imaging findings. In the remaining case, new dissection events were observed. All cases were managed conservatively, and no death was reported. Conclusions: In this series of patients, spontaneous dissection of visceral arteries had a benign, favorable course, requiring only conservative management.

Introdução: As variações anatômicas das artérias hepáticas e do tronco celíaco são de grande importância para cirurgias laparoscópicas, transplantes hepáticos, intervenções radiológicas e tratamento de lesões abdominais. O grande aumento de intervenções minimamente invasivas deixou os atos cirúrgicos com menos espaço para o reconhecimento de estruturas anatômicas. Métodos: Foi realizado um estudo retrospectivo do banco de dados do Hospital São Vicente de Paulo durante o ano de 2016, analisando imagens abdominais de tomografia computadorizada com contraste e angiotomografias que envolvem a aorta abdominal e seus ramos um total de 461 imagens foram analisadas. Resultados: Dos 461 pacientes analisados, 86,9% apresentaram a conformação usual do tronco celíaco cuja anatômica é a origem tríplice com as artérias gástrica esquerda, esplênica e hepática comum e artéria mesentérica superior se originando sozinha da aorta abdominal. Dentre as anatomias anômalas (13%), o padrão mais comum desses ramos foi a presença em 4,5% de um tronco hepatomesentérico e um tronco gastroesplênico. No sistema arterial hepático a conformação mais prevalente foram as artérias hepáticas direita e esquerda sendo ramos da hepática próprias em 66,3%. Das alterações anatômicas (33,2%), as mais comuns foram a presença de uma artéria hepática esquerda acessória ramo da artéria gástrica esquerda (7,8%). Conclusão: Variações anatômicas do sistema arterial hepático e do tronco celíaco são prevalentes, podendo apresentar diversos arranjos organizacionais. (AU)
Introduction: Anatomical variations in the hepatic arteries and the celiac trunk are of great importance for laparoscopic surgeries, liver transplants, radiological interventions and treatment of abdominal injuries. A large increase in the number of minimally invasive interventions hampered the recognition of anatomical structures in surgical procedures. Methods: A retrospective study was performed using the 2016 São Vicente de Paulo Hospital database of contrast-enhanced abdominal computed tomography images and computed tomography angiographies showing the abdominal aorta and its branches. In total, 461 images were analyzed. Results: Of the 461 patients analyzed, 86.9% had usual conformation of the celiac trunk, which trifurcates into the left gastric artery, the common hepatic artery and the splenic artery, while the superior mesenteric artery originates alone from the abdominal aorta. Among the cases of anomalous anatomy (13%), the most common pattern in these branches was the presence of a hepatomesenteric trunk and a gastrosplenic trunk in 4.5%. In the hepatic arterial system, the most prevalent conformation was the right and left hepatic arteries being branches of the hepatic artery proper in 66.3%. Of all anatomical variations (33.2%), the most common were the presence of a left accessory hepatic artery of the left gastric artery (7.8%). Conclusion: Anatomical variations in the hepatic arterial system and the celiac trunk are common, having different structural arrangements. (AU)
