Yale Medicine Surgeons Among First to Employ Branched Stent Graft System for Minimally Invasive Treatment of Thoracoabdominal Aortic Pathologies

A multidisciplinary team of surgeons from Yale's Aortic Institute and the Division of Vascular Surgery and Endovascular Therapy, both part of Yale New Haven Health’s Heart and Vascular Center, is among the first in the country to employ a novel aortic stent graft system for the minimally invasive treatment of thoracoabdominal aortic aneurysms.

  • Ask the Experts: Does Treating Type II Endoleaks and the Aneurysm Sac Make a Difference?

    Nearly 30 years after the implantation of the first aortic endograft, the natural history and hemodynamic and clinical significance of type II endoleaks remain controversial. The coexistence and concomitant treatment of other types of endoleaks continue to prevent meaningful conclusions from being drawn regarding the significance of successful treatment of an isolated type II endoleak. Type II endoleaks may simply represent the nidus of a more intricate endoleak flow pattern—one that may involve subtle seal zone leaks not detected by current imaging techniques. Given that these endoleaks occur in thrombus-ridden aneurysm sacs with unpredictable flow channels, dynamic, high-resolution, real-time, four-dimensional imaging may be the only means of detecting these endoleaks that may pressurize the sac spontaneously and intermittently. Close surveillance of all type II endoleaks is warranted, with emphasis on evaluation for subtle type I and/or type III endoleaks.

    Dr. Nassiri's novel techniques on direct stick embolization of fast-flow extremity arteriovenous malformations and multimodal embolotherapy of persistent embryonic veins in Klippel-Trenaunay and CLOVES Syndromes were highlighted in the most recent International Society for Study of Vascular Anomalies (ISSVA) Newsletter. They were highlighted as two of the more influential peer reviewed articles on endovascular management of vascular malformations.
