RESUMEN
BACKGROUND: Visceral artery aneurysms (VAA) are rare with an incidence of up to 0.2% and mortality of up to 40%. Aneurysms larger than 5 cm are referred to as giant visceral artery aneurysms (GVAA). We present a case of a celiac artery aneurysm of 14 cm which required endovascular and surgical management. A review of the literature with focus on treatment is also provided. CASE PRESENTATION: In this case report, a 76-year-old male presented with postprandial nausea and vomitus. An ultrasound and computed tomography scan showed an aneurysm of the celiac artery of approximately 14 cm. Initial treatment was conducted with coiling. Despite this treatment, patient presented again with the same complaints, most likely due to gastric outlet syndrome caused by the aneurysm sac. Partial open removal of the aneurysm sac was performed with release of the duodenum. Due to recurring dysphagia and postprandial nausea, a gastroenterostomy was created, which was later supplemented with a Roux-en-Y anastomosis due to gastroparesis. Patient recovered uneventful after the Roux-en-Y and was discharged from the hospital. CONCLUSION: Giant visceral artery aneurysms sometimes need multimodal treatment. We showed that an endovascular first approach of a giant visceral artery aneurysm is not only technically feasible, but it also facilitates subsequent open surgery due to limiting blood loss and reducing the need for extensive mobilisation of the viscera to gain arterial control.

BACKGROUND: Chronic limb-threatening ischemia (CLTI) has a high mortality and amputation risk even after revascularization. Owing to an aging population the incidence of peripheral arterial disease is rising. However, the current age distribution in patients with CLTI and the impact of age on outcomes remains unclear. For this reason we performed an age-dependent analysis of mortality, morbidity, and amputation-free survival after open surgical revascularization (OSR) and endovascular revascularization therapy (ERT) with identification of risk factors for mortality. Standardized mortality ratios (SMR) were calculated, comparing observed deaths in the study population to expected deaths based on age and gender specific mortality rates of the overall Dutch population. METHODS: Patients revascularized for the first episode of CLTI between 2013 and 2018 were included in this multicenter retrospective cohort study. The cohort was divided into 2 treatment groups (OSR and ERT) who were each stratified in 3 age groups: early age group < 65 years (G1), middle age group 65-74 years (G2), and elderly age group ≥ 75 years (G3). RESULTS: During the study period 274 limbs (43.9%) were treated with OSR and 350 limbs (56.1%) with ERT. The young population (G1) is only a small part of the whole CLTI population, namely for OSR 22% and ERT 18%. The risk profile of the early age group was characterized by male gender and smoking, whereas the elderly age group was characterized by poor arterial runoff, tissue loss, hypertension, hypercholesterolemia, chronic kidney disease, history of heart disease, chronic obstructive pulmonary disease, and cerebrovascular disease. One year amputation rates were similar between the age groups. However, significantly higher one-year mortality rates were observed in patients ≥ 75 years in comparison to the low mortality rates in patients < 75 years (OSR: G3 19.8% vs. G2 7.1% and G1 6.7%, P = 0.006; ERT: G3 30.7% vs. G2 12.7% and G1 7.8%, P = 0.001). The SMR in this elderly group equaled 3.72 after OSR and 4.04 after ERT. Independent risk factors for mortality after OSR were age, hazard ratio (HR) 1.03 (95% confidence interval [CI] 1.01-1.06; P = 0.006), preoperative hemoglobin level (HR 0.79; 95% CI 0.67-0.92; P = 0.003), tissue loss (HR 1.85; 95% CI 1.22-2.79; P = 0.004), cardiac history (HR 1.56; 95% CI 1.06-2.30; P = 0.024), and development of postoperative delirium (HR 2.75; 95% CI 1.61-4.71; P < 0.001). After ERT we identified age, HR 1.06 (95% CI 1.04-1.08; P < 0.001); preoperative hemoglobin level, HR 0.75 (95% CI 0.65-0.87; P < 0.001); tissue loss, HR 1.71 (95% CI 1.15-2.53; P = 0.008); history of chronic obstructive pulmonary disease, HR 1.99 (95% CI 1.43-1.79; P < 0.001); history of cerebrovascular accident (CVA), HR 1.55 (95% CI 1.09-2.21; P = 0.015); the development of postoperative pneumonia, HR 2.27 (95% CI 1.24-4.16; P = 0.008); postoperative acute kidney injury (AKI), HR 2.42 (95% CI 1.29-4.54; P = 0.006); and postoperative CVA, HR 8.17 (95% CI 1.96-34.15; P = 0.004) as risk factors. CONCLUSIONS: The current CLTI population consists mostly of elderly patients and only a small part is younger than 65 years. This shift in the population is important because increasing age is associated with considerable higher one-year mortality rates regardless of the method of revascularization in patients with CLTI. The mortality rates in the elderly group are 3 to 4 times larger than expected in the general population. In relation to the high mortality of the elderly patient, we assume that interventions to prevent postoperative delirium and correct preoperative anemia may be warranted as they appear to be independent risk factors for mortality.
