Regarding “Long-Term Evaluation of Percutaneous Groin Access for EVAR”
- 37 Downloads
We read with great interest the article by Dwivedi et al . The use of percutaneous access for endovascular aneurysm repair is associated with high success rate and low incident of complications. The authors observed that accessed vessels do not show evidence of stenosis or thrombosis on routine follow-up CT scans performed at 30 days and annually thereafter.
However, the authors do not report vessel diameter on the preoperative imaging. The comparison is between postoperative scans. It could be argued that any change in diameter secondary to the use of a closure device is best assessed by comparing scans before and after the use of the device. Additional review of the pre-procedure CT to assess effect of the procedure on vessel diameter would be very informative.
