Purpose: Mechanical thrombectomy is an established tool for endovascular therapy of acute/chronic in-stent occlusions of the lower extremities, especially for the superficial femoral artery. The authors report the use of the Rotarex catheter system for an in-stent proximal subclavian occlusion.
Case Presentation: A 51-year-old female patient with previous multiple attempts at left subclavian revascularization; primary endovascular stenting at the origin of the subclavian artery occluded at 3 months, and a carotid-subclavian bypass was placed distally to the stent. After 6 months from the first treatment, the patient was readmitted with an acute left arm ischemia and full occlusion of the bypass was confirmed at computed tomography angiography. An anterograde thrombectomy for in-stent restenosis, together with PTA with a drug-eluting balloon was performed in the subclavian artery with confirmed patency at 6 months.
Conclusion: Mechanical thrombectomy together with drug-eluting balloon PTA for in-stent occlusion or restenosis of the subclavian artery could be a promising procedure with a lower invasivity and risk with respect to surgical options.

The subclavian artery's intrathoracic segment is a rare peripheral artery aneurysm site. Common causes are atherosclerosis, trauma, vasculitis, and infection. Subclavian artery aneurysms have a higher propensity for rupture, thrombosis, embolization, and compression of surrounding structures, thus necessitating urgent surgical care.

The intra-aortic balloon pump (IABP) is a widely-used mechanical circulatory support device that enhances hemodynamics in patients with heart conditions. Although the IABP is a common clinical tool, its effectiveness in enhancing outcomes for patients with acute myocardial infarction and cardiogenic shock remains disputed. This study aimed to assess the effectiveness of intra-aortic dual-balloon pump (IADBP) and its impact on aortic hemodynamics compared with an IABP.

The optimal management of acute type A aortic dissection (ATAAD) remains a controversial subject. While some surgeons opt for a hemiarch approach to minimize bypass and cross-clamping time, others prefer partial or total arch replacement to prevent the need for additional operations. The advent of hybrid approaches offers a variety of options to the aortic surgeon in treating ATAAD.

With advancements in medical devices and imaging techniques, endovascular treatment using stent grafts has emerged as a viable and aggressive therapeutic option for traumatic subclavian artery injuries, including iatrogenic cases. Existing literature suggests that endovascular treatment is less invasive and offers hemostatic success rates comparable to traditional surgical methods. However, there is a paucity of case reports, necessitating further investigation into treatment indications and procedural challenges.

Introduction: Management of patients with large aortic arch aneurysms who are considered high risk for frozen elephant trunk technique have been challenging, especially when they have a dilated ascending aorta (AA) that precludes total endovascular branched repair (arch BEVAR). A viable option in our armamentarium is wrapping of the AA (AW), and zone 0 Ishimaru TEVAR.
Methods: Retrospective analysis of our aortic database from 2013 to 2024 to select high-risk patients with aortic arch aneurysm that had an AW and TEVAR.
