NOTE: The information entered in this event notice was received from the licensee as a result of an audit ordered by the Ohio Department of Health for all brachytherapy procedures performed by the licensee since November 2004. This incident was referenced in Ohio NMED Item # OH100003. [See EN # 46272]
On 12/10/08 the licensee performed a prostate seed implant with fifty-four (54) I-125 seeds prescribed to deliver a dose of 145 Gray [104.76 Gray actually delivered] to the prostate. During the procedure, six (6) seeds were 'stuck' in one needle, and inadvertently placed inferior to the prostate. The post implant dosimetry calculation performed on 2/12/09 showed a D90 of 72.25%, resulting in an underdose to the prostate greater than 20% of the prescribed dose.
Ohio NMED Item # OH100019.
