Hybrid Approach for Treatment of a Symptomatic Giant Splenic Artery Aneurysm

Abstract: A 56-year-old female presented with a symptomatic giant fusiform mid-splenic artery aneurysm (7.3 x 6.4 cm). The patient underwent hybrid management of the aneurysm with endovascular embolization of the aneurysm and inflow splenic artery followed by laparoscopic splenectomy with control and division of the outflow vessels. The patient had an uneventful post-operative course. This case demonstrates the safety and efficacy of an innovative, hybrid management of a giant splenic artery aneurysm with endovascular e… Show more

Objective. This article was composed to review the profile of giant splenic artery aneurysm as reported in the recent literature. Methodology. A systematic literature search was conducted through electronic databases and scientific networking sites, including PubMed, Scopus, and Google Scholar, using the key words and terms “giant splenic artery aneurysm”, “large splenic artery aneurysm”, and “huge splenic artery aneurysm”. Only literature in English was considered for inclusion in this study, and the time frame was fixed between 2014 and 2024. Results. 16 cases, including 9 (56.25%) females and 7 (43.75%) males, ranging in age from 35 to 84 years (mean 60.4±13.4 years). Years were included in the review. The size of aneurysm varied from 10 cm to 30.68 cm (mean 12.54±5.32 cm). Upper abdominal pain was the commonest presentation, along with shock and palpable lumps. The majority of the cases (n = 11; 68.7%) were managed by laparotomy, and an endovascular approach was adopted in 4 (25%) cases. Conclusion. Giant splenic artery aneurysm (GSAA) is a rare but potentially life-threatening condition. Physicians need to be aware of this condition so that a diagnosis is made promptly. There is no role of conservative management, and all giant aneurysms need appropriate treatment after detection. Open surgical aneurysmectomy is the mainstay of management.

Introduction. Splenic artery aneurysms refer to the most common visceral artery aneurysms. However, they are diagnosed quite rarely, since about 80% of them appear asymptomatic. Clinically, splenic artery aneurysms manifest themselves through their complications, including hemorrhage into pancreatic cysts or intraabdominal bleeding due to their rupture, leading to lethality up to 8.5%. Other complications of splenic artery aneurysms appear extremely rare. The gold standard for the diagnosis of splenic artery aneurysms refers to digital subtraction angiography that enables their exact localization to be determined and aneurysm embolization to be performed. Materials and methods. In the period from 2015 to 2023, we observed 51 patients who underwent endovascular interventions on the splenic artery for hypersplenism (n = 32) and aneurysms (n = 19). In most cases, the aneurysms were asymptomatic. The paper presents a rare clinical case of splenic artery aneurysm complicated by recurrent intestinal bleeding. Results and discussion. Examination (EGD, CS) did not detect the source of recurrent intestinal bleeding. Contrast CT revealed a splenic artery aneurysm. Celiac angiography detected a large aneurysm (52×41 mm) of the splenic artery, closely adjacent to the lower horizontal branch of the duodenum. Endovascular embolization of the splenic artery was performed proximal to the aneurysm, resulting in complete occlusion of blood flow through the splenic artery and aneurysm. No repeated episodes of intestinal bleeding were observed after the intervention, thereby indicating the effectiveness of hemostasis. No signs of splenic ischemization were detected by clinical and examination data due to the preservation of blood flow through short splenic vessels. Conclusion. Endovascular embolization of the splenic artery is found to be an effective treatment for its complicated aneurysms.

Background/Objectives: Giant splenic artery aneurysms (SAAs) and pseudoaneurysms (SAPs) represent rare conditions, characterized by a diameter greater than or equal to 5 cm. The risk of rupture is increased compared to common SAAs and SAPs, necessitating urgent treatments to prevent it. Methods: This systematic review was conducted through a comprehensive search involving the PubMed, Google Scholar, and Scopus databases. A total of 82 patients and 65 articles were included in the analysis. For each patient, we investigated age, sex, symptoms, comorbidities, the presence of a true or a false aneurysm, the dimensional criteria used to define dilations as giant aneurysms or pseudoaneurysms, the dimension of the two greatest diameters, imaging studies, surgical treatment, post-operative length of stay (LOS), and post-operative follow-up. Results: The results revealed a similar incidence in both genders (43 males vs. 39 females) with a median age of 55.79 years. The most frequently described symptom was pain (59.76%). Thirteen cases were false aneurysms and 69 were true aneurysms. The mean greatest diameter was 9.90 cm. The CT scan was the most utilized imaging study (80.49%). Open, endovascular, and hybrid surgery were performed in 47, 26, and 9 patients, respectively, with complication rates of 14.89%, 23.08%, and 22.22% occurring for each treatment. The post-operative LOS was 12.29 days, 2.36 days, and 5 days, respectively. The median follow-up was 17.28 months overall. No recanalization was observed after endovascular procedures during the follow-up period. Conclusions: The dimensional criterion to define SAAs and SAPs as giant was most frequently that at least one diameter was ≥ 5 cm. The CT scan was the most frequently utilized radiological study to diagnose giant SAAs and SAPs. Finally, endovascular procedures, open surgeries, and hybrid treatments presented similar post-operative complication rates. The post-operative LOS was lower for the endovascular group, and the follow-up period did not show aneurysm recanalization in any patients.
