We describe a case of Takotsubo cardiomyopathy in an 88-year-old woman who underwent endovascular aneurysm repair (EVAR) for an abdominal aortic aneurysm. The patient developed cardiac arrest shortly after the surgery. Following immediate resuscitation, her electrocardiogram showed extensive ST segment elevation in leads V2-V6, and echocardiography revealed apical akinesis with basal hyperkinesis. Emergency coronary angiography confirmed the absence of coronary lesions, and she was diagnosed with Takotsubo cardiomyopathy. Her cardiac function improved within a few days following the administration of catecholamines. Although EVAR is a less invasive surgical procedure, it may trigger Takotsubo cardiomyopathy. Prompt diagnosis and appropriate management of Takotsubo cardiomyopathy are essential to treat critical conditions in the acute phase.

The Endologix AFX is a bifurcated unibody endovascular aortic repair (EVAR) system used for the treatment of abdominal aortic aneurysms (AAA). It consists of an inner metal endoskeleton with multiple metal struts covered by a polytetrafluoroethylene graft fabric, which is suitable for treating AAA with narrowed abdominal aortic bifurcations. However, the risk of type 3 endoleak (T3EL) has been alerted and it is recommended that a sufficient overlap length be considered when using a cuff device on the central side. We present the case of an 81-year-old man with a 45 mm AAA who underwent EVAR with an AFX2 main body device and AFX proximal cuff extension device, adhering to the recommended overlap length. However, postoperative aneurysm enlargement occurred gradually, and complete uncoupling of the main body and cuff was observed 4 years later. A retrospective review of 4 years of computed tomography (CT) scans revealed potential caudal migration of the main body device and cranial migration of the cuff device, potentially resulting in a type 3a endoleak (T3aEL). An additional device was deployed to bridge both components, and the patient was discharged without complications. In cases where an AFX2 main body device and a cuff device are used on the central side, even with adequate overlap, careful follow-up is necessary because of the potential for sideways displacement or craniocaudal migration. The observation of device displacement using 3D reconstruction CT imaging is particularly useful.

Surgery for a shaggy aortic aneurysm requires a meticulous strategy to prevent embolic complications since the complications are associated with longer length of hospital stay and higher mortality. However, until now, there are no established treatment options to prevent embolic complications. We report a case of a 75-year-old man with a descending aortic aneurysm and a shaggy aorta who underwent thoracic endovascular aortic repair (TEVAR) with major branch artery protection. During the procedure, we placed balloon catheters in the left subclavian and left common iliac arteries, a filter device in the superior mesenteric artery, and a sheath at the ostium of the right common iliac artery. The patient did not develop embolic or other complications and was discharged on the eighth postoperative day. Our strategy of using the balloon occlusion technique and filter placement at the major vessels effectively prevented embolic complications during TEVAR for a shaggy aorta.
