RESUMO
Background: The treatment choice of visceral artery aneurysms in an elective setting is debated. The durability and the risk of reintervention with endovascular treatment are still reasons for concern, whereas open surgery is invasive and burdened by major complications. In anecdotal reports and isolated studies, robotic-assisted surgery seems to provide the possibility of a minimally invasive treatment and the durability of traditional open surgery, but the literature supporting this view is scarce. This review aims to collect the results of robotic-assisted surgery in the treatment of visceral artery aneurysms. Methods: A systematic search of the main research databases was performed: the study endpoints were mortality and conversion rates, perioperative morbidity, and freedom from late complications and reinterventions. Results: We identified 16 studies on 53 patients. All cases underwent successful resection, with three conversions to laparoscopy. Perioperative and aneurysm-related mortality were nil. Over a median follow-up of 9 months, two reinterventions were reported (3.6%). Conclusion: The robotic technique is safe and effective in treating splenic and renal artery aneurysms, and it should be considered as a valuable alternative to endovascular and open repair, although larger sample sizes and a longer-term follow-up are necessary to confirm such results.
RESUMO
BACKGROUND: The arc of Bühler (AOB) is a residual embryonal anastomosis between the celiac artery (CA) and the superior mesenteric artery (SMA). Although usually asymptomatic, it has clinical relevance when compensatory reverse flow between the SMA and the CA in response to celiac artery obstruction leads to aneurysm formation and bleeding. Endovascular coiling is the mainstay therapy because of the deep AOB retropancreatic location, which hinders open surgery. CASE PRESENTATION: We herein report a case of a 2.8-cm AOB saccular aneurysm and LAM compression of celiac trunk in a 47-year-old man during rehabilitation following motorcycle trauma and vertebral surgery. The patient was considered unsuitable for surgery. Neither conventional coiling nor bare-metal stent and balloon-assisted techniques for coiling were suitable because of the wide necked saccular shape of AOB aneurysm interposed between the SMA and the floor of celiac trunk. To exclude the aneurysm from direct SMA inflow and permit safe and efficient coiling to rule out retrograde sac perfusion, a 9-mm polytetrafluoroethylene stent graft (Viabahn; Gore, Phoenix, AZ, USA) was positioned in the mesenteric artery, followed by antegrade periprosthetic high-density packed coiling of the aneurysm. The AOB remained excluded from mesenteric perfusion. The patient's clinical condition and abdominal contrast-enhanced multislice computed tomographic findings were unremarkable at the 9-year follow-up. CONCLUSION: The 9 year long-term efficacy in our case raises the possibility that perigraft coiling following stent-graft deployment in the SMA may represent a valuable technical option for large Bühler aneurysms that are not amenable to stand-alone coiling.
RESUMO
INTRODUCTION: Sutton-Kadir Syndrome (SKS) describes true inferior pancreaticoduodenal artery (IPDA) aneurysms in the setting of coeliac artery (CA) stenosis or occlusion. Although rare, SKS aneurysms can rupture and cause morbidity. Due to its rarity and lack of controlled treatment data, correct treatment for the CA lesion is currently unknown. Our aim was to assess if endovascular embolisation alone was safe and effective in treatment of SKS aneurysms, in emergent and elective settings. Secondary objectives were to describe presentation and imaging findings. METHODS: A retrospective cohort study of patients treated at Sir Charles Gairdner Hospital between January 2014 and December 2021 was done. Data on presentation, diagnostics, aneurysm characteristics, CA lesion aetiology, treatment and outcomes were extracted from chart review. RESULTS: Twenty-four aneurysms in 14 patients were identified. Rupture was seen in 7/15 patients. Most aneurysms (22/24) were in the IPDA or one of its anterior or posterior branches. Median arcuate ligament (MAL) compression was identified in all. There was no difference in median (IQR) maximal transverse diameter between ruptured and non-ruptured aneurysms (6 mm (9), 12 mm (6), P = 0.18). Of ruptures, 6/7 had successful endovascular embolisation and 1/7 open surgical ligation. Of non-ruptures, 6/7 had successful endovascular embolisation, 1/7 open MAL division then endovascular CA stenting and aneurysm embolisation. No recurrences or new aneurysms were detected with computed tomography or magnetic resonance angiography over a median (IQR) follow-up period of 30 (10) months in 12 patients. CONCLUSION: Endovascular embolisation of SKS aneurysms without treatment of MAL compression is safe and effective in both the emergent and elective settings.

Abstract Splenic artery pseudoaneurysm is the most common of all the visceral artery pseudoaneurysms. Presentation is often variable and the condition demands immediate diagnosis and management because pseudoaneurysm rupture increases morbidity and mortality. It is associated with pancreatitis and other conditions like abdominal trauma, chronic pancreatitis, pseudocyst of the pancreas, liver transplantation, and, rarely, peptic ulcer disease. We present a case of a giant splenic artery pseudoaneurysm measuring 14x8 cm. Proximal and distal control of the vessels could not be achieved during the procedure because of local adhesions and inflammation and it was necessary to cross clamp the supraceliac aorta to control bleeding.
Resumo O pseudoaneurisma de artéria esplênica é o mais comum entre os pseudoaneurismas de artérias viscerais. A apresentação geralmente varia e requer diagnóstico e tratamento imediatos, pois a ruptura do pseudoaneurisma aumenta a morbimortalidade. Esse tipo de pseudoaneurisma está associado à pancreatite e a outras condições, como trauma abdominal, pancreatite crônica, pseudocisto de pâncreas, transplante de fígado e, raramente, úlcera péptica. Apresentamos um caso de pseudoaneurisma gigante de artéria esplênica, com tamanho de 14x8 cm. Durante o procedimento, não foi possível alcançar controle proximal e distal dos vasos devido a aderências locais e inflamação, sendo necessário o clampeamento da aorta supracelíaca para controle do sangramento.
RESUMO
Resumo Relatamos o caso de um paciente masculino, 77 anos, portador de hipertensão arterial, sem outras comorbidades ou fatores de risco para coronariopatia. Apresentava-se assintomático e, durante exame de ultrassonografia abdominal de rotina, foi diagnosticada uma massa vascular hepática de, aproximadamente, 5 cm de diâmetro. Foi solicitada angiotomografia computadorizada abdominal, que evidenciou aneurisma de artéria hepática de até 5,2 cm de calibre máximo, 7,2 cm de extensão no maior eixo longitudinal e calibre máximo da luz verdadeira de 3,0 cm. Optou-se por realização de correção endovascular do aneurisma com implante de três endopróteses vasculares revestidas Lifestream 7x58 mm, 8x58 mm e 8x37 mm sequenciais, com sucesso, conseguindo-se direcionamento do fluxo pelas próteses, levando à exclusão do aneurisma. O paciente evoluiu assintomático, mesmo 2 anos após o implante, sem intercorrências clínicas. Controle com dúplex arterial, realizados 6 e 12 meses após o procedimento, evidenciaram bom fluxo pelas endopróteses, sem "leak" para o saco aneurismático.
Abstract We report a case of an asymptomatic, 77-year-old, male patient with arterial hypertension and no other comorbidities or risk factors for coronary disease. During a routine abdominal ultrasound examination, he was diagnosed with a hepatic vascular mass with an approximate diameter of 5 cm. Abdominal computed angiotomography was requested, showing an aneurysm of the hepatic artery, with maximum diameter of up to 5.2 cm, longest longitudinal axis of 7.2 cm, and a maximum true lumen caliber of 3.0 cm. We opted for endovascular aneurysm repair with implantation of three sequential Lifestream covered vascular stents (7x58mm, 8x58mm, and 8x37mm), successfully diverting the flow through the stents and excluding the aneurysm. The patient remains asymptomatic and free from clinical complications 2 years after the procedure. Control examinations with arterial duplex ultrasound 6 and 12 months after the procedure showed good flow through the stents with no leakage into the aneurysmal sac.

Resumen La hemorragia digestiva alta se define como el sangrado originado en el tracto digestivo superior, proximalmente al ángulo de Treitz, y constituye la urgencia gastroenterológica más importante. Tiene una incidencia que varía, según el área estudiada, entre 48 y 160 casos por 100 000 habitantes y año. Aunque puede ser causada por numerosas etiologías, no debemos olvidar aquellas menos comunes, ya que pueden condicionar una alta mortalidad, como es el caso de la rotura de un aneurisma de la arteria hepática. A continuación, mostramos un caso representativo.
Abstract Upper gastrointestinal bleeding is defined as bleeding originating in the upper digestive tract proximal to the Treitz angle and is the most important gastroenterological emergency. Its incidence varies, depending on the area studied, between 48 and 160 cases per 100,000 inhabitants per year. Although it can be caused by numerous etiologies, we must not forget the less common ones such as a ruptured hepatic artery aneurysm since they can condition high mortality. We present a representative case.
