“…Pseudoaneurysms are caused by rupture of the intima and media and then swelling of the adventitia, usually due to infection, iatrogenic injury, and inflammatory reaction; these are very prone to rupture. In literature pseudoaneurysms tend to be more symptomatic than true aneurysms 2 , 5 . The most common VAA is splenic aneurysm with an incidence of approximately 60%, followed by hepatic aneurysm which accounts for approximately 20% of cases 6 , 7 .…”

To assess the safety and efficacy of endovascular embolization techniques, we compared the short- to medium-term prognosis of coil embolization for symptomatic visceral aneurysms (SVAA) and asymptomatic visceral aneurysms (ASVAA) to identify risk factors associated with 30-day mortality. Explore the symptom profile and intrinsic associations of SVAA. A retrospective study of 66 consecutive patients at two tertiary care hospitals from 2010 to 2020 compared the short- to mid-term outcomes of 22 symptomatic VAAs and 44 asymptomatic VAAs treated with coil embolization. Univariate and log-rank tests were used to analyze the prognostic impact of SVAA and ASVAA. SVAA group had significantly higher 30-day mortality than ASVAA group (2(9.1%) vs 0, P = 0.042), both patients who died had symptomatic pseudoaneurysms. Perioperative complications such as end-organ ischemia (P = 0.293) and reintervention (P = 1) were similar in both groups. No difference in event-free survival was identified between the two groups (P = 0.900), but we found that the majority of pseudoaneurysms were SVAA (4/5) and that they had a much higher event rate than true aneurysms. In addition, dyslipidemia may be an influential factor in the development of VAA (P = 0.010). Coil embolization is a safe and effective method of treatment for VAA. Most pseudoaneurysms have symptoms such as abdominal pain and bleeding, and in view of their risk, more attention should be paid to symptomatic patients and the nature of the aneurysm should be determined as soon as possible to determine the next stage of treatment.

“…True aneurysms have an intact vascular structure and are caused by the expansion of the entire blood vessel [4]. Pseudoaneurysms are caused by rupture of the intima and media and then swelling of the adventitia, usually due to infection, iatrogenic injury, and in ammatory reaction; these are very prone to rupture [2,5]. The most common VAA is splenic aneurysm with an incidence of approximately 60%, followed by hepatic aneurysm which accounts for approximately 20% of cases [6,7].…”

Objectives To compare the short- to mid-term prognosis of coil embolization for symptomatic visceral artery aneurysm (SVAA) and asymptomatic visceral artery aneurysm (ASVAA), to identify risk factors associated with 30-day mortality. Explore the symptomatic features and intrinsic associations of SVAA. Method A retrospective study of 66 consecutive patients at two tertiary care hospitals from 2010-2020 compared the short- to mid-term outcomes of 22 symptomatic VAAs and 44 asymptomatic VAAs treated with coil embolization. Univariate and log-rank tests were used to analyze the prognostic impact of SVAA and ASVAA. Results Dyslipidemia were significance differences between the two groups(P=0.010). SVAA group had significantly higher 30-day mortality than ASVAA group (2(9.1%) vs 0, P=0.042), both patients who died had symptomatic pseudoaneurysms. Perioperative complications such as end-organ ischemia (0.293) and reintervention (P=1) were similar in both groups. No difference in event-free survival was identified between the two groups(P=0.900), but we found that the majority of pseudoaneurysms were SVAA (4/5) and that they had a much higher event rate than true aneurysms. Conclusion Coil embolization is a safe and effective method of treatment for VAA. Most pseudoaneurysms have symptoms such as abdominal pain and bleeding, and in view of their risk, more attention should be paid to symptomatic patients and the nature of the aneurysm should be determined as soon as possible to determine the next stage of treatment.
