“…Although hypercoabulable conditions have been noted post procedure in the setting of renal cell carcinoma ablations, (11, 12, 16, 17) no study has examined the incidence over time of these events in patients who underwent cryoablation for renal masses. We hypothesized that there may be a higher rate of thrombotic events in cryoablation patients compared to controls over time based on 1) data describing alterations in systemic inflammation and thrombosis after cryoabaltion (described below), 2) our subjective experience with renal cryoablation, 3) a suspicion that these events were excluded by traditional time limited periprocedural complication reporting, (18, 19) and 4) the notion that because thrombotic phenomena related to cryoablation may be separated in time from the physical procedure and occur in patients with underlying malignancy, they may be misinterpreted independent events.…”

Purpose To retrospectively identify hypercoagulable events that occurred over time in patients who underwent image guided percutaneous renal cryoablation, and compare the incidence to a cohort of patients who underwent surgical partial nephrectomy (PN) during the same time period. Methods An electronic medical record database was queried for patients who underwent percutaneous image guided renal mass cryoablation or PN between September 2006 and June 2012. Records were examined for thrombotic events during the year following the procedure in each group. Incidence rates, Kaplan-Meier estimates, and patient demographic variables were compared using the stratified log-rank test and the t-test for independent samples. Results One hundred fourteen cryoablation cases were included. The cumulative incidence of thrombotic events after 1-year was 4.39%. The incidence per 100 person-years was 4.84. One hundred five PN cases were included. The cumulative incidence of thrombotic events after 1-year was 1.0%. The incidence per 100 person-years was 1.14. The person-time incidence rate difference for these two groups did not reach statistical significance (p = 0.0894). Conclusion The incidence of thrombotic events in patients who underwent percutaneous renal cryoablation in this study was not significantly different than a comparable cohort who underwent surgical PN during the same time period.
