OBJECTIVE: To predict @entity2759 after endovascular stent graft repair of descending thoracic @entity449 , temporary interruption of the intercostal arteries (including the @entity439 ) was performed by placement of a novel retrievable stent graft (Retriever) in the aorta under evoked spinal cord potential monitoring. METHODS: From February 1995 to October 1997, endovascular stent graft repair of descending thoracic @entity449 was performed in 49 @entity1 after informed consent was obtained. In 16 @entity1 with @entity439 located in the middle and distal segment of the descending aorta, the Retriever was placed temporarily before stent graft deployment. The Retriever consisted of two units of self-expanding zigzag stents connected in tandem with stainless steel struts. Each strut was collected in a bundle fixed to a pushing rod, and the stent framework was lined with an expanded @entity736 sheet. The Retriever was delivered beyond the @entity439 through a sheath and was retracted into the sheath 20 minutes later. A stent graft for permanent use was deployed in @entity1 whose predeployment test results with the Retriever were favorable. Evoked spinal cord potential was monitored throughout placement of the Retriever and stent grafting until the next day. RESULTS: The Retriever was placed in 17 @entity439 in 16 @entity1 . There were no changes in amplitude or latency of evoked spinal cord potential records obtained before or during Retriever placement. After withdrawal of the Retriever, all @entity439 were excluded from circulation immediately after permanent stent grafting. There were no changes in evoked spinal cord potential, nor were @entity51 seen after stent graft deployment in any @entity1 . CONCLUSIONS: These results suggest that predeployment testing with the Retriever under evoked spinal cord potential monitoring is promising as a predictor of @entity2759 in candidates for stent graft repair of thoracic @entity449 .
