Management of sudden severe artery stenosis during transcatheter aortic valve replacement: a case report of rare complications caused by failed suture of severely tortuous femoral artery

Abstract Background Vascular closure devices are commonly used instruments in TAVR, and severe vascular stenosis or occlusion is a serious complication. Therefore, the correct use of vascular suturing devices and the timely management of complications are particularly important. Case summary We report a case of severe femoral artery stenosis that occurred after the use of a vascular closure device during transfemoral transcatheter aortic valve replacement. This is due to the severe curvature of the patient's blood vessels and the incorrect tactile feedback when using ProGlide, which in turn led to iatrogenic severe vascular stenosis. The cause of this complication is rare.By implanting a lower limb vascular stent, the blood flow in the lower limb was quickly restored. Discussion Our experience reminds operators to be more cautious when using ProGlide in patients with severely tortuous blood vessels. Once severe vascular stenosis or acute vascular occlusion occurs, vascular interventional therapy should be carried out as early and as soon as possible.
