AI Article Synopsis
- This study examined the safety and effectiveness of endovascular embolization for treating very small ruptured anterior communicating artery (AcomA) aneurysms in 81 patients from 2015 to 2020.
- Results showed that 72.8% of aneurysms achieved complete occlusion immediately after the procedure, with a low complication rate of 2.5%, all being transient issues.
- Follow-up data revealed a strong long-term occlusion rate of 91.7% and a favorable clinical outcome, with 90.2% of patients having good recovery, indicating that coiling treatment is both safe and effective for these aneurysms.
Article Abstract
Objective: This study aimed to investigate the safety and efficacy of endovascular embolization for very small ruptured anterior communicating artery (AcomA) aneurysms.
Methods: From August 2015 to June 2020, 81 patients with very small (≤3 mm) ruptured AcomA aneurysms treated endovascularly were enrolled in this study. Clinical and radiographic data were analyzed retrospectively, including the aneurysm occlusion rate, complications, and clinical outcome.
Results: Among 81 patients, simple coiling embolization was performed in 52 cases and stent-assisted embolization in 29 cases. Immediate angiography demonstrated complete occlusion in 59 (72.8%) aneurysms, residual neck in 20 (24.7%) aneurysms, and residual lumen in 2 (2.5%). Procedure-related complications rate was 2.5% (2 of 81), all of which were transient thromboembolic events. Angiographic follow-up outcomes of 60 patients (mean: 6.8 ± 3.2 months) revealed complete occlusion in 91.7% (55 of 60), with recurrence in 1 patient. The mean clinical follow-up time was 22.6 ± 11.4 months and good prognosis rates (6-month modified Rankin Scale score: 0-2) reached 90.2% (73 of 81). The differences in aneurysm occlusion and procedure-related complications between the simple coiling group and the stent-assisted coiling group were not statistically significant.
Conclusions: Coiling with or without stent-assisted technique for the treatment of very small ruptured AcomA aneurysms was safe and effective.

The Impact of Physical Activity on Abdominal Aortic Aneurysm: A Scoping Review.

Department of Clinical Diagnostics, School of Health and Welfare, Jönköping University, Jönköping, Sweden.
Background: Abdominal aortic aneurysm (AAA), a condition primarily affecting older men, is often asymptomatic but becomes life-threatening if rupture occurs. While AAA risk factors such as age, gender, and smoking are well-studied, physical activity (PA) may also play a critical role in managing AAA progression, though this relationship remains understudied. This scoping review aims to synthesize current knowledge on the impact of PA on AAA, examining safety, physiological effects, and potential protective effects against AAA progression.

Background: Portal venous system aneurysms (PVA) are increasingly diagnosed on cross-sectional computed tomography (CT) imaging. However, the natural history of these aneurysms is poorly understood and reports are limited to small case series.
Methods: Terms relevant to PVA were searched in radiology reports (2010-2022) with PVA presence confirmed by manual review.

Purpose: Ovarian mature cystic teratoma (MCT) is the most common ovarian tumor, and only a small fraction undergoes malignant transformation. The most prevalent malignant type of the ovary is squamous cell carcinoma, followed by adenocarcinoma. However, ruptured ovarian mature cystic teratoma with adenocarcinoma transformation is extremely rare.
