The azygoesophageal recess (AER) is known as a possible cause of bulla formation in patients with spontaneous pneumothorax. However, there has been little focus on the depth of the AER. We evaluated the relationship between the depth of the AER and pneumothorax development.
We conducted a retrospective study of 80 spontaneous pneumothorax patients who underwent surgery at our institution. We evaluated the depth of the AER on preoperative computed tomography scans.
Ruptured bullae at the AER were found in 12 patients (52.2%) with secondary spontaneous pneumothorax (SSP) and 8 patients (14.0%) with primary spontaneous pneumothorax (PSP) (p < 0.001). In patients with ruptured bullae at the AER, 10 SSP patients (83.3%) had a deep AER while only 2 PSP patients (25%) had a deep AER (p = 0.015).
A deep AER was more frequently associated with SSP than with PSP. A deep AER may contributes to bulla formation and rupture in SSP patients.
奇静脉食管隐窝（AER）被认为是自发性气胸患者肺大疱形成的一个可能原因。然而，很少有人关注AER的深度。我们评估了AER深度与气胸发生之间的关系。
我们对在我院接受手术的80例自发性气胸患者进行了一项回顾性研究。我们在术前计算机断层扫描上评估了AER的深度。
在12例（52.2%）继发性自发性气胸（SSP）患者和8例（14.0%）原发性自发性气胸（PSP）患者中发现了AER处的肺大疱破裂（p < 0.001）。在AER处有肺大疱破裂的患者中，10例SSP患者（83.3%）有较深的AER，而只有2例PSP患者（25%）有较深的AER（p = 0.015）。
较深的AER与SSP的相关性比与PSP的相关性更高。较深的AER可能导致SSP患者肺大疱的形成和破裂。
