Study finds low risk in treating previously coile...(lt University the State University of Ne...),Health

The research group had previously documented the low risk associated with angiographic screening for aneurysm recurrence in patients who had undergone aneurysm coiling. When considering the option of coiling, Ringer says, "Physicians must consider the risks of both aneurysm screening (surveillance) and retreatment."

A potential bias in the retreatment study, Ringer points out, was the surgeons' selection of those patients who would undergo retreatment with coiling. It is possible, he said, that surgeons chose not to perform retreatment procedures on patients whose recurrent or residual aneurysm was too dangerous.
