Cerebral hemodynamics in symptomatic anterior circulation intracranial stenosis measured by angiography-based quantitative flow ratio: association with CT perfusion
ConclusionsμQFR was associated with CTP in patients with symptomatic anterior circulation ICAS and may be a potential marker for real-time hemodynamic evaluation during interventional procedures.Key Points• Murray law–based QFR (μQFR) is associated with CT perfusion parameters in intracranial atherosclerotic stenosis and can differentiate hypoperfusion from normal perfusion.• Post-intervention μQFR, collateral score, and current smoking status are independent factors associated with improved perfusion after treatment.

Endovascular Treatment of Transplant Renal Artery Stenosis: A Single-Center Retrospective Cohort Study
CONCLUSIONS: Endovascular therapy is effective in transplant renal artery stenosis treatment and has a low incidence of complications. Percutaneous transluminal angioplasty should be performed routinely during endovascular therapy. After dilation, if stenosis remains >25% or retracted, then percutaneous transluminal stenting is recommended. Otherwise, percutaneous transluminal angioplasty is preferred.PMID:36987798 | DOI:10.6002/ect.2022.0400 (Source: Experimental and Clinical Transplantation : official journal of the Middle East Society for Organ Transplantation)
