Objective: To describe our experience with endoluminal stent graft repair of aortobronchial fistulas.
Methods: We reviewed the records of patients treated with endoluminal stent grafting of aortobronchial fistulas at a private teaching hospital. All patients underwent the following diagnostic studies: computed tomography, angiography, bronchoscopy, and transesophageal echocardiography. With standard endovascular techniques, two different devices were implanted.
Results: Between March 1997 and October 2000, we treated four patients with postsurgical fistulas. The patients were diagnosed with hemoptysis between 3 and 23 years after aortic replacement grafting for thoracic aneurysms. Diagnostic studies varied in their ability to find the fistula. Transesophageal echocardiography most reliably demonstrated the fistula in the patients. All were successfully treated by exclusion with endoluminal stent grafting. The patients had no complications and no further episodes of hemoptysis.
Conclusion: Endoluminal stent grafting of aortobronchial fistulas is feasible and may become the preferred method of management in patients at high risk.

Evaluation of in-stent restenosis after carotid artery stenting with superb microvascular imaging: initial findings.
Acta Radiol

Background: Carotid artery stenting (CAS) is an interventional management in preventing ischemic stroke caused by carotid artery stenosis. After the treatment with CAS, in-stent restenosis caused by neointimal hyperplasia may develop.
Purpose: This study aims to obtain a better determination of neointimal hyperplasia using superb microvascular imaging (SMI), which provides a high-quality visualization of the endoluminal lesions, and to compare these results with B-mode and Doppler ultrasound (US).

Background: In recent years, transcatheter implantation devices to restrict pulmonary arterial flow have emerged as a potential alternative to surgical pulmonary artery banding.
Case Presentation: A term male was diagnosed with critical aortic stenosis (AS) and severely reduced left ventricle (LV) systolic function. He underwent aortic balloon valvuloplasty on day 2 of life, resulting in some antegrade flow, but LV ejection fraction only improved to 15%.
Fatal complications of aortoesophageal fistula caused by pseudoaneurysm following esophageal stent placement: A case report.

Rationale: Aortoesophageal fistula (AEF) is an exceedingly rare yet critically life-threatening condition, with mortality rates nearing 100% if not addressed promptly. AEF often develops in the context of thoracic aortic aneurysms, esophageal malignancies, or as a complication of foreign body ingestion and prior thoracic aortic surgeries. This study reports an exceptionally severe and clinically rare case of AEF associated with a pseudaneurysm induced by esophageal stenting.

Background: Three-dimensional printing (3DP) enables the production of highly customised, cost-efficient devices in a relatively short time, which can be particularly valuable to clinicians treating patients with palliative care intent who are in need of timely and effective solutions in the management of their patients' specific needs, including the relief of distressing symptoms.
Method: Four online databases were searched for articles published by December 2020 that described studies using 3DP in palliative care. The fields of application, and the relevant clinical and technological data were extracted and analysed.

Introduction: The Flow Re-direction Endoluminal Device (FRED) is a novel flow diverter with a unique double stent design, with an inner stent composed of 48 nitinol wires, and an outer stent with 16 nitinol wires. It is designed for endovascular cerebral aneurysm treatment, although, limited data exist regarding in-stent stenosis (ISS) rates associated with FRED devices.
Methods: A registry encompassing two North American comprehensive stroke centers was the base of this study.
