Purpose: To report the patency rates after implantation of an interwoven nitinol stent to salvage failing arteriovenous grafts (AVGs) caused by intragraft stenoses.
Methods: Between May 2018 and May 2020, 21 Supera stents were placed in 20 patients (18 women; mean age: 79.9 years) who had a failing AVG due to repeat intragraft stenoses.
Background: Complications associated with upper gastrointestinal (UGI) endoscopy are uncommon, and rarely involve those of cardiovascular nature. We report herein a unique case of spontaneous superior mesenteric artery dissection (SMAD) after UGI pandenoscopy.
Case Summary: A 45-year-old man who had previously undergone UGI panendoscopy and colonoscopy during a voluntary health check-up at our facility was admitted to the emergency room (ER) at the same facility due to persistent epigastric pain with radiation to the back.
Article Synopsis
- A 74-year-old man with chronic kidney disease experienced asystole and was treated with mechanical chest compressions and anti-hyperkalemia measures, achieving return of spontaneous circulation (ROSC) within 10 minutes.
- After ROSC, the patient transitioned to pulseless electrical activity, and an ultrasound revealed significant pericardial fluid indicating cardiac tamponade.
- A bedside pericardiotomy and subsequent open thoracotomy revealed a right ventricular wall laceration due to chest compressions, but after surgical repair and care, the patient recovered fully by day 6, highlighting the role of POCUS in unexpected deteriorations during resuscitation.
Background: In this study, we investigated the patency of endovascular stent grafts in haemodialysis patients with arteriovenous grafts, the modes of patency loss, and the risk factors for re-intervention.
Patients And Methods: Haemodialysis patients with graft-vein anastomotic stenosis of their arteriovenous grafts who were treated with endovascular stent-grafts between 2008 and 2013 were entered into this retrospective study. Primary and secondary patency, modes of patency loss, and risk factors for intervention were recorded.
Background: We report the initial experience of modified four-branched graft technique for proximal aorta and arch repair, feasibly combined with antegrade thoracic endovascular aortic repair (TEVAR) to extend distal aortic reconstruction in acute type A aortic dissection.
Methods: From 2011 to 2013, 12 consecutive patients with acute type A aortic dissection were indicated for arch surgery and underwent surgical replacement of proximal aorta, arch replacement or debranching procedure, and concomitant TEVAR for distal aortic repair.
Results: A good surgical field was obtained in all patients.
Aberrant right subclavian artery aneurysms are rare but carry a high risk of spontaneous rupture without any treatment. Aggressive early elective treatment is warranted. We present a hybrid endovascular treatment that was used to treat a 77-year-old woman with aberrant right subclavian artery aneurysm for whom surgical treatment would have been associated with high risk.

The purpose of this study is to determine the value of intraoperative blood flow measurement with respect to AVF short-term outcome.
Methods: A prospective cohort study enrolled patients undergoing first time AVF creation surgery for hemodialysis from November 2001 to April 2007.
