AI Article Synopsis
- - The text discusses a rare complication called pseudoaneurysm that can occur in the right ventricular outflow tract (RVOT) after cardiac surgeries, particularly in a 3-month-old infant with tetralogy of Fallot and pulmonary atresia.
- - The patient was critically ill with septic shock and very high pressure in the right ventricle, requiring urgent treatment to avoid high-risk surgery.
- - The successful management involved using a Gore VBX balloon expandable covered stent to exclude the pseudoaneurysm and stenting the pulmonary arteries to relieve pressure, highlighting the importance of recognizing this condition and available treatment options.
Article Abstract
Pseudoaneurysm formation within the right ventricular outflow tract (RVOT) is a rare but serious complication following cardiac surgeries involving the RVOT. This report presents the case of a 3-month-old, 4 kg infant with tetralogy of Fallot and pulmonary atresia, previously treated with ventricular septal defect closure and right ventricle (RV)-pulmonary artery homograft placement. The patient presented critically ill with septic shock and suprasystemic RV pressure. A high-risk surgical approach was averted through the endovascular exclusion of the pseudoaneurysm using a Gore VBX balloon expandable covered stent, in addition to stenting of bilateral proximal branch pulmonary arteries to alleviate RV hypertension. This case underscores the multifactorial nature of RVOT pseudoaneurysm formation and the importance of a high index of suspicion for diagnosis. Management options, including surgical and transcatheter strategies, are discussed, focusing on the successful use of a covered stent for stabilization in a critically ill patient.

Purpose: This study aims to develop and implement an economic evaluation using a micro-costing approach to provide a precise and transparent analysis of the direct costs of cystoscopic procedures in Korean hospitals. The study seeks to identify key cost components and evaluate whether current reimbursement rates accurately reflect these direct costs.
Materials And Methods: Significant variations in cost items were identified across different studies.

Ascending aortic pseudoaneurysm may pose significant risk for reoperative repair. We describe an 18-year-old man who presented with bacteremia and a large, mycotic ascending aortic pseudoaneurysm 3 months after redo cardiac surgery. A covered stent graft sealed the pseudoaneurysm neck and facilitated safe reentry into the mediastinum.

A 54-year-old man underwent right S6 segmentectomy for right lung cancer. After discharge, he presented with fever, hemoptysis, and cough, and computed tomography showed an intermediate bronchus fistula. Because direct closure or bronchoplasty was challenging, a Dumon (Novatech) stent was inserted directly into the fistula from the surgical field and covered with an autologous pericardial patch, pedicled mediastinal fat, and intercostal muscle.

Purpose: The AVeNEW Post-Approval Study (AVeNEW PAS) follows upon results from the AVeNEW IDE clinical trial and was designed to provide additional clinical evidence of safety and effectiveness using the Covera™ Vascular Covered Stent to treat arteriovenous fistula (AVF) stenoses in a real-world hemodialysis patient population.
Materials And Methods: One hundred AVF patients were prospectively enrolled at 11 clinical trial sites in the USA and treated with the covered stent after angioplasty of a clinically significant target stenosis. The primary safety outcome was freedom from any adverse event that suggests the involvement of the AV access circuit evaluated at 30 days.

Objectives: Mal-deployment of the thoracic endovascular aortic repair (TEVAR) stent graft during a frozen elephant trunk (FET) procedure for an acute type A aortic dissection (ATAAD) leads to devastating complications. We report a hemiarch replacement with TEVAR stent graft covering the aortic arch vessels salvaged through an endovascular approach.
Methods: A 69-year-old man with ATAAD in 2018, status post-hemiarch repair with TEVAR, presented in 2023 with progressive dizziness/syncope and lower extremity hypertension with inability to tolerate anti-hypertensives.
