An oral presentation titled “Vessel patency post Irreversible Electroporation ablation – a 15 month follow up,” was given March 26, 2012. The authors included Doctors Govindarajan Narayanan, Geetika Arora, Jose Yrizarry, David Quintana, Umamaheshwari Mukkamalla, Katuska Barbery and Peter Hosein of the University of Miami, Miami, Fla.Ablation using the NanoKnife ® System was performed in 79 procedures on 56 patients between January 2010 and June 2011. Overall, narrowing or thrombosis occurred in three out of 84 vessels in close proximity to the treatment zone. An oral presentation titled “Percutaneous Irreversible Electroporation of Surgically Unresectable Pancreatic Carcinoma: Single Center Safety Experience,” was given March 26, 2012. The authors included Doctors Sandeep Bagla, Dimitrios Papadouris, and Arina van Breda, of INOVA Alexandria Hospital, Springfield, Va. In this clinical experience, four consecutive patients with surgically unresectable pancreatic carcinoma received seven ablations of five tumors. No mortalities occurred within 30 days. No episodes of intra-operative arrhythmia occurred. Intra-operative transient hypertension occurred with all treatments. No patients had prolonged hypertension after completion of the procedure with the NanoKnife System. There were no incidents of hemorrhage, infection, pancreatic fistula, or bowel injury. One treatment was complicated by partial splenic infarction, which required no treatment. No patients required analgesics on discharge. An oral presentation titled “Percutaneous irreversible electroporation in the treatment of hepatocellular carcinoma (HCC) and metastatic colorectal cancer (mCRC) to the liver,” was given March 26, 2012. The authors included Doctors Govindarajan Narayanan, Katuska Barbery, Jose Yrizarry, and Peter Hosein of the University of Miami, Miami, Fla. Forty-nine patients underwent percutaneous ablation of unresectable HCC and mCRC liver tumors using the NanoKnife System. A total of 76 lesions were treated in 62 sessions. After a procedure with the system, 20 patients had a complete response, 19 had a partial response and one had stable disease as their best response. Two of the HCC patients were transplanted. The Kaplan-Meier estimated average progression free survival was 11.3 months for all patients, 11.6 for HCC patients, and 10.4 months for mCRC patients. Six patients experienced complications during the procedure of the following types: pneumothorax, pleural effusion and atrial flutter during anesthesia. All patients recovered fully from these complications. One patient died within one month of a procedure with the NanoKnife System due to disease progression.
In the United States, NanoKnife has been cleared by the FDA for use in the surgical ablation of soft tissue. NanoKnife has not been cleared for the treatment or therapy of a specific disease or condition.About AngioDynamics AngioDynamics, Inc. is a leading provider of innovative, minimally invasive medical devices used by professional healthcare providers for vascular access, surgery, peripheral vascular disease and oncology.
