BackgroundCompression of the trachea, bronchi, and pulmonary arteries are complications in patients with large thoracic aortic aneurysms. In this case, we report unexpected cardiopulmonary collapse manifested by general anesthesia before surgery in an asymptomatic patient with a large thoracic aortic aneurysm.Case presentationWe present the case of a 32-year-old man with a 10-cm aneurysm in the ascending aorta. A total aortic arch replacement was planned. After intravenous anesthesia, his aneurysm occluded the left main bronchus and right pulmonary artery simultaneously, and induced severe hypoxia. Percutaneous cardiopulmonary support was conducted and the patient recovered from cardiopulmonary collapse successfully. After the patient regained consciousness from anesthesia, the findings of organ compressions disappeared. At the second surgery, percutaneous cardiopulmonary support was initiated with local anesthesia before general anesthesia and intubation. The operation was performed successfully without any adverse events.ConclusionWe experienced a case of hemodynamic collapse induced by general anesthesia in a patient of an unruptured thoracic aortic aneurysm. It is important to recognize that fatal organ compression might be caused by general anesthesia even in asymptomatic patients with thoracic aortic aneurysm.

“…Pulmonary artery compression caused by aortic dissection is rare, but, in such cases, if the right pulmonary artery is compressed, the clinical signs may mimic pulmonary embolism (2,3). Sugimoto et al (4) described one patient with a large aneurysm of the aortic arch that caused severe hypoxia by compressing the left main bronchus and the right pulmonary artery. Our patient had a similar form of compression but his lesion was an aneurysm of the ascending aorta.…”

Large aneurysms of the ascending aorta occasionally cause severe hemodynamic disturbance by compression. We describe the case of an 18-yr-old man who presented with dyspnea and developed hemodynamic collapse during computed tomography scanning. Computed tomography during resuscitation revealed that the aneurysm was compressing both the right pulmonary artery and the left bronchus. Emergency surgery was performed, but the patient died because of generalized cerebral infarction.

“…Aort anevrizması olan hastalarda nonkardiyak cerrahi nedeniyle anestezi uygulaması çeşitli riskleri beraberinde getirmektedir. Aortanın diseksiyonu, rüptürü, akut hipovolemi, kardiyak tamponat, aortik valv regürjitasyonu, miyokard enfarktüsü, trakeobronşial ve pulmoner arter basısı, akut kardiyovasküler kollaps bu riskler arasında sayılabilir (1,2). Bu olgu sunumunda multinodüler guatr nedeniyle elektif tiroidektomi operasyonu planlanan aort anevrizmalı bir hastadaki anestezi uygulamamızı sunmayı amaçladık.…”

Anevrizma ve diseksiyon başlıca torasik aort hastalıklarıdır. Günümüzde torasik aort hastalığı prevalansı ve insidansının arttığı ve literatürde önceden bildirene göre yüksek olduğu vurgulanmaktadır. Torasik aort anevrizmaları genellikle asemptomatiktirler. Akut ve sıklıkla yıkıcı bir komplikasyon ortaya çıkana kadar kolaylıkla saptanamazlar. Torasik aort anevrizmalı hastalar nonkardiyak bir cerrahi operasyon geçirmek zorunda kalabilirler ve bazen anevrizma, hastamızda olduğu gibi preoperatif değerlendirme sırasında tanınabilir. Bu olguda nonkardiyak cerrahi geçiren asendan aort anevrizmalı bir hastadaki anestezi uygulamamızı sunmayı amaçladık.
