正中弓状韧带综合征 (MALS) 的腹腔镜手术：52 名患者的前瞻性队列

选择 MALS 患者进行手术治疗取决于症状解释和诊断检查的可靠性。 旨在跟踪 MALS 患者腹腔镜减压的结果。

在一个单中心，52 名连续的 MALS 患者在经腹膜腹腔镜减压后进行了前瞻性随访。 MALS 被诊断为计算机断层扫描血管造影 (CTA) 证实狭窄，腹腔动脉 (CA) ≥ 50%，并通过双相超声诊断，峰值收缩速度 (PSV) ≥2.0 m/s。 进行术后、CTA 和多普勒超声检查，并在 3、6、12 个月和之后每年对患者进行随访。

患者的平均年龄为 47 ± 21 岁，65% 为女性。 患者的平均体重减轻为 8.4 ± 7.2 kg。 51 例患者接受了腹腔镜手术，平均手术时间为 102±28 分钟。 47 名患者 (90%) 在 3-6 个月的随访中完全 (67%) 或部分 (23%) 的症状得到缓解。 与术前值相比，术后 PSV 有显著改善，p<0.001。 五名患者 (10%) 的手术没有立即影响，但其中两名在平均 2.4 ± 2 年的研究随访期间没有出现症状。 5例（10%）患者出现手术并发症，包括1例肝套管针损伤、1例气胸、3例CA分支出血。 两名患者在研究期间死于癌症。 只有两名患者 (4%) 的症状复发，但后来都得到了成功治疗。

腹腔镜经腹膜减压为大多数患者提供了 MALS 症状的持续缓解。
