研究目的:

通过深度学习人工智能算法,建立准确、高效、泛化能力强的腹主动脉腔内修复术后瘤囊体积动态测定算法,有助于临床快速、准确测算患者瘤囊体积,辅助筛选高危病人,助力临床决策。  

Objectives of Study:

By leveraging deep learning-based artificial intelligence algorithms, this study establishes a highly accurate, efficient, and generalizable dynamic measurement method for assessing aneurysm sac volume following endovascular repair of the abdominal aorta. The proposed approach facilitates rapid and precise clinical evaluation of aneurysm sac volume, supports the identification of high-risk patients, and aids in informed clinical decision-making.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.所有明确诊断为腹主动脉瘤、行腹主动脉瘤腔内修复手术(EVAR)且临床资料齐全的患者;

Inclusion criteria

1.All patients with a confirmed diagnosis of abdominal aortic aneurysm who underwent endovascular aneurysm repair (EVAR) and had complete clinical data were included.

排除标准:

1. 临床资料缺失和/或结局事件缺失严重;
2. 影像资料伪影严重、图像质量无法用于后续分析;
3. 患者发生非瘤囊扩张相关并发症;
4. 随访期间行腹部手术干预或其他可能导致影响瘤囊的治疗或行为。

Exclusion criteria:

1. Severe lack of clinical data and/or outcome events;
2. The image data exhibit severe artifacts, rendering the image quality unsuitable for subsequent analysis;
3. The patient developed complications unrelated to sac dilation;
4. During the follow-up period, abdominal surgical interventions or other treatments or activities that could potentially affect the aneurysmal sac were performed.

Outcomes:

指标中文名:

腹主动脉瘤瘤囊体积

指标类型:

主要指标

Outcome:

The volume of the abdominal aortic aneurysm sac

Type:

Primary indicator

测量时间点:

收集患者的术前影像资料和术后 1 月、3 月、6 月、1 年、2 年的影像资料

测量方法:

软件重建掩膜后由多名经验丰富的医生,通过ITK-SNAP测量腹主动脉瘤瘤囊体积,范围从肾动脉下缘到双侧髂内外动脉分支。较前比较,体积缩小超过5%,视为回缩;增大超过5%,视为扩张;其余视为稳定。

Measure time point of outcome:

Acquire imaging data of patients, and follow-up imaging data at 1 m, 3 m,6m, 12 and 24 m.

Measure method:

Following software-based reconstruction of the aneurysm mask, a multidisciplinary team of board-certified vascular radiologists and interventional specialists quantified the volume of the abdominal aortic aneurysm (AAA) sac using ITK-SNAP. Volume measurements were performed along the craniocaudal axis, spanning from the inferior margin of the renal arteries to the bifurcation into the left and right common iliac arteries—and subsequently to the origins of the internal and external iliac artery b
