Severe carotid stenosis or occlusion may cause insufficient blood flow and lead to distal artery wall collapse and extensive lumen contraction. Whether this 'adaptive narrowing' can restitute after carotid recanalization is unclear. We report a patient with global ischemia due to occlusions of bilateral carotid and right vertebral arteries. The occluded left carotid was recanalized successfully with angioplasty and stenting. The adaptively narrowed distal carotid did not restitute immediately but regained its morphology 1 week after the procedure. Carotid adaptive narrow distal occlusion or stenosis may not regain its original morphology immediately but several days after recanalization. This knowledge is instructive for treating occlusive carotid diseases.

Intracranial atherosclerosis (ICAS) is a major cause of ischemic stroke, disproportionately affecting populations with significant vascular risk factors. Although ICAS imposes a considerable health burden, research on this condition in Central Asia remains scarce, especially among the Kazakh population. This study analyzes demographic characteristics, treatment outcomes, and procedural challenges associated with ICAS in 216 patients treated at a single institution.

Coronary calcification is a major factor leading to stent under-expansion, and subsequent adverse events. This meta-analysis aimed to evaluate the short and long‑term outcomes of rotational atherectomy (RA), followed by modified balloon (cutting or scoring) (MB) versus plain balloon before drug‑eluting stent implantation for calcified coronary lesions. We searched PubMed, Web of Science (WOS), Scopus, and the Cochrane Library Central Register of Controlled Trials (CENTRAL), from inception until 30 January 2024.

Background: Evaluating health status changes following transfemoral carotid artery stenting (TF-CAS) is essential for assessing procedural success, but meaningful clinical changes are unknown. We aimed to determine minimal clinically important differences (MCIDs) and quantify health status improvement or worsening rates after TF-CAS using the Stenting and Angioplasty with Protection in Patients at High Risk for Endarterectomy (SAPPHIRE) registry data.
Methods: The SAPPHIRE registry included patients undergoing TF-CAS from 2010 to 2014 for both symptomatic and asymptomatic carotid stenosis.

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.

The mediastinal vasculature can be affected by various etiologies in cancer patients. Both direct and indirect sequela of cancer may result in life-threatening clinical presentations. Tumor growth may cause vessel narrowing and decreased blood flow from either extrinsic mass effect, invasion into the vascular wall, or tumor thrombus within the lumen.
