Resumé

Introduction: Ice ball fracture is a rare complication in cryoablation of renal tumors potentially causing hemorrhage. Iceball fracture are seen during laparoscopic cryo, but has rarely been reported during CT guided Cryo ablation worldwide. During a 4 year period > 150 cryoablations were performed at our institution. The risk of significant complication is very low compared to surgery and thus, the purpose of the current case presentation is to emphasize radiological and clinical signs of the condition and the importance of awareness of ice ball fractures. Methods: A 82-year old female patient with renal papillary adenocarcinoma was referred to CT guided cryoablation of a medium sized tumor (Ø3.3 cm) in the right kidney. The procedure was performed in general anesthesia using a Siemens Somatom Flash 128 slice CT scanner. Three 90 degrees angle IceRod 1.5 CX needles were positioned in the tumor. After a freezing period of 10 minutes and a defrosting period of 8 minutes the ice ball fractured during the second freezing cycle. Two control scans were performed; one before and one after needle extraction and blood pressure was monitored to exclude active bleeding. Results: The control scans showed a lambda-shaped air-filled fracture line emerging from the anterior kidney wall (fig. 1). There was no evidence of active bleeding and the patient was discharged later the same day. Conclusion: Complication rate during cryoablation is very low and it seems to be an effective and safe treatment of kidney tumors. However, it is important to recognize complications, such as ice ball fractures during cryoablation.
