| ENS 45206 | 15 July 2009 12:54:00 | A prostate seed implant was performed on March 5th, 2009, using needles preloaded with I-125 seeds. After implanting a total of 61 seeds, 22 seeds were found and then retrieved from the bladder. The patient later returned for a pelvic CT for post implant dosimetry. This dosimetry revealed an under dosing of the prostate with a D90 dose less than 80% of the prescribed dose. The seed distribution error was caused by the position of the needles in respect to depth when the seeds were released. The patient received no ill effect, but requires further therapeutic radiation in order to complete the prescription. The patient is currently scheduled for a second seed implant to complete the therapy. A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient. |
