Safety assessment of cyanoacrylate closure for treatment of varicose veins in a large-scale national survey in Japan.

Objective: Cyanoacrylate closure (CAC) is a minimally invasive technique for treating axial venous reflux. However, the incidence of serious adverse events (AEs) related to CAC is concerning. With an increasing number of patients undergoing CAC and insufficient safety data in Japan, this study aimed to investigate the safety profile of CAC, focusing on the types and incidence of AEs.

[Vascular Prosthesis Perforation Caused by a Stent Graft Inserted into the Innominate Artery after Total Aortic Arch Replacement].

The patient was a 60-year-old woman who underwent thoracoabdominal aorta replacement for type B aortic dissection three years ago and aortic root replacement and total aortic arch replacement due to asymptomatic type A aortic dissection two years previously. Her clinical course was uneventful until follow-up computed tomography (CT) disclosed anastomotic insufficiency in the innominate artery and left main coronary artery stenosis owing to hematoma. Emergent percutaneous coronary intervention and stent graft insertion into the innominate artery were performed successfully.

Two-Year Results of a Multicenter Prospective Observational Study of the Zenith Spiral-Z Limb Deployed in the External Iliac Artery During Endovascular Aneurysm Repair.

Background: Limited data is available on the use of a polyester graft limb with a helical stent configuration deployed in the external iliac artery (EIA) during endovascular aneurysm repair (EVAR), so we prospectively analyzed the efficacy of the Zenith Spiral-Z limb deployed in the EIA.

Methods and results: Patients undergoing EVAR using a Zenith stent-graft and Spiral-Z limb deployed in the EIA were prospectively registered in 24 Japanese institutions from June 2017 to November 2017. In total, 65 patients (74 limbs) (mean age: 77.

Leaflet escape in an Edwards TEKNA mitral prosthesis.

In almost every type of artificial valve, structural failure has been described. We are reporting on a case of a sudden leaflet escape of an Edwards TEKNA mitral valve prosthesis 12 years after implantation. The patient had a sudden onset of dyspnea and severe pulmonary edema with subsequent cardiogenic shock.
