Is Chimney EVAR an Acceptable Endovascular Technique ?

Chimney technique in the endovascular management of complex aortic disease.

The objective of this study was to systematically review the literature reporting on the chimney technique and perform an analysis of the outcomes. A search of electronic databases was undertaken to identify all studies reporting on the outcome of the chimney technique. The selected articles were divided into those reporting on the treatment of aortic pathology involving the visceral and those ...

Persistent Type I Endoleak after Endovascular Treatment with Chimney Technique

Thoracic endovascular aortic repair (TEVAR) is increasingly used in the treatment of acute type B aortic dissection. Type Ia endoleaks are a common complication of the procedure, but its clinical significance and the best treatment strategy remain poorly defined. We present a case of a type Ia endoleak following TEVAR in the treatment of acute type B aortic dissection. Chimney technique approac...

Endovascular Aortic Aneurysm Repair (EVAR)

Over the past 20 years the availability of aortic stent-grafts has allowed a major step change in the management of abdominal aortic aneurysms (AAA). Prior to this open surgical resection, first described by Charles Dubost in 1950, was the mainstay of AAA management(1). For elective cases open surgical repair has now largely been superseded by the deployment of a covered stent (stent-graft) thr...

Postoperative “Chimney” for Unintentional Renal Artery Occlusion after EVAR

Renal artery obstruction during endovascular repair of abdominal aortic aneurysm using standard device is a rare but life-threatening complication and should be recognized and repaired rapidly in order to maintain renal function. Both conventional surgery and endovascular stenting have been reported. We report a case of late postoperative bilateral "chimney" to resolve a bilateral thrombosis of...
