A Ruptured Thoracoabdominal Aortic Aneurysm Managed Endovascularly Using the Telescoping Chimney Technique

Extending the proximal landing zone to facilitate endovascular repair of aortic aneurysms with short proximal necks using the chimney, top-fenestration, or snorkel technique has been previously reported. In addition, extending the distal landing zone using the periscope technique has also been recently described. In this study, we used an extended chimney technique, the “telescoping technique,” to successfully treat a ruptured Crawford type III thoracoabdominal aortic aneurysm in a patient with pre-existing renal failure and an occluded superior mesenteric artery.
