Ascending aortic pseudo-aneurysm treated with 'coil and plug'

Abdominal Stent-Graft Treatment of Ascending Aortic Pseudoaneurysm Following Transcatheter Aortic Valve Implantation

An ascending aortic pseudoaneurysm is a potentially lethal complication in aortic procedures. We present a hybrid approach using surgical innominate artery access and the endovascular insertion of an abdominal stent-graft extension to successfully treat a zone 0 ascending aortic pseudoaneurysm in a patient with a prior valve-in-valve transcatheter aortic valve implantation.

Ascending aorta thoracic endovascular aortic repair for infected pseudoaneurysm

A 70-year-old woman with a bioprosthetic aortic valve replacement for aortic valve endocarditis complicated by recurrent endocarditis and requiring homograft aortic root replacement 10 years earlier had presented at 1 month after her admission for pseudomonal bacteremia with right-sided chest pain. An aortic pseudoaneurysm, identified on computed tomography, was treated with an ascending aorta thoracic endovascular aortic repair using two overlapping abdominal aortic stent grafts in the ascending aorta. Postoperative and follow-up imaging demonstrated exclusion of the pseudoaneurysm with stable positioning of the stent grafts. Ascending aorta thoracic endovascular aortic repair can be performed safely with good short-term results in patients presenting with infected pseudoaneurysms of the ascending aorta.

Case Report: Ascending Aortic Pseudo-Aneurysm Following Ventricular Septal Defect Repair in a 4-Year-Old Girl

Pseudo-aneurysm is a fatal disease, and the main cause of death is massive hemorrhage secondary to the rupture of the aneurysm. This case report aims to evaluate the effects of pseudo-aneurysm excision procedure on the disease. A 4-year-old girl was readmitted on the 20th day after ventricular septal defect (VSD) closure procedure with a high fever of 40°C; aortic pseudo-aneurysm was suspected based on a spherical cystic echo (82 × 76 mm) of the ascending aorta which was detected by ultrasonic cardiogram, and the diagnosis was confirmed by an aortic computed tomograph angiography (CTA) examination and intraoperative findings. Treatment included emergency pseudo-aneurysm excision procedure and antibiotic therapy. The aortic pseudo-aneurysm was surgically removed under deep hypothermia and circulatory arrest. Antibiotics were applied according to the bacterial culture results. The pseudo-aneurysm was excised successfully, and the patient achieved a good recovery. Our case suggests that the postoperative ascending aortic pseudo-aneurysm was probably due to inappropriate purse-string suture and/or local or systematic infection, so extra precautions should be taken to avoid this life-threatening complication.

Tailored approaches for transcatheter closure of postsurgical pseudoaneurysms from the ascending aorta and brachiocephalic artery

Ascending aortic pseudoaneurysms following open-heart surgery are treated by redo surgery or endovascular therapy when surgical risks are high. Extreme variations in their morphology, proximity to coronary and arch branches and vascular access may vary the timing, strategy, device choice, and technique in each patient. Three patients with varying etiology, presentations, and morphology of the pseudoaneurysms underwent successful endovascular exclusion by individually tailored strategies. The approach includes optimal treatment of the underlying infections before the endovascular intervention despite the emergency to treat the condition; choosing appropriate device depending on the proximity to aortic branches, choosing appropriate access depending on the angulation of the entry of pseudoaneurysm to the aortic lumen, and use of adequate imaging for achieving procedural success. <Learning objective: A tailored approach for transcatheter closure of postsurgical ascending aortic pseudoaneurysms should include: 1 Optimal infection control before the intervention. 2 Choosing nitinol occluders in high-flow aneurysms; vascular plugs and coils for residual leaks; and embolic protection for high clot burden. 3 Choice of femoral, brachial, or transapical access is decided based on angulation of the aneurysm with ascending aorta. 4 Meticulous planning of the interventions based on advanced three-dimensional imaging.>.
