For atrioventricular nodal reentrant tachycardia (AVNRT) patients, the electrophysiological efficacy indices during successful slow-pathway (SP) cryoablation have not yet been established. We examined progression of A-H interval cryofreezing successfully achieving SP elimination and compared prolongation to unsuccessful attempts. Fifty patients that underwent with slow-fast AVNRT were enrolled....

BACKGROUND AND PURPOSE While partial nephrectomy remains the gold standard for the management of most small renal masses, increasing experience with renal cryoablation has suggested a viable alternative with a favorable morbidity profile and good efficacy. We report intermediate-term oncologic outcomes from a single-center experience with laparoscopic and percutaneous renal cryoablation. PATI...

BACKGROUND Percutaneous cryoballoon ablation is a commonly used procedure to treat atrial fibrillation. One of the major limitations of the procedure is the inability to directly visualize tissue damage and functional gaps between the lesions. We seek to develop an approach that will enable real-time visualization of tissue necrosis during cryo- or radiofrequency ablation procedures. METHODS ...

The efficacy and safety of the long-term experience with targeted cryoablation of prostate cancer (TCAP) at a community hospital is retrospectively reviewed. A series of 590 consecutive patients who underwent TCAP as primary therapy with curative intent for localized or locally advanced prostate cancer from March 1993 to September 2001 were identified. Patients were stratified into 3 risk group...

OBJECTIVE The purpose of this study was to investigate the factors predicting the maintenance of sinus rhythm in patients with paroxysmal atrial fibrillation (PAF) who underwent cryoablation of the pulmonary veins (PVs). METHODS Fifty-one patients (54.6±10.4 years) with paroxysmal AF who underwent the cryoablation of the PVs were to the prospective trial. The clinical risk factors and echocar...

BACKGROUNDS/AIMS The prognosis of hepatic resection for hepatocellular carcinoma (HCC) in patients with cirrhosis is worse than in those without cirrhosis. In Korea, the hepatitis B virus prevalence rate is higher than in other countries. Therefore, we investigated patients' clinicopathologic and metabolic factors that affect the postoperative outcomes of hepatic resection for HCC in our hospit...

In this study, we determined the number of peripheral blood circulating tumor cells (CTCs) pre- and post-cryosurgery in patients with colorectal cancer liver metastasis as a reference for understanding the relevance of any changes to the efficacy of cryosurgery. CTC numbers and CTC-related gene expression were measured in the peripheral blood of 55 patients with colorectal liver metastasis at 1...

OBJECTIVE Cryosurgery is a minimally invasive cancer treatment that uses liquid nitrogen or supercooled argon to freeze and destroy tumors. To achieve complete ablation of the prostate, we have developed a computer program that can determine treatment effects by calculating iceball formation. This is based on a three-dimensional (3D) model of the patient's prostate constructed from ultrasound i...

BACKGROUND Locoregional treatments of hepatocellular carcinoma (HCC) have evolved over the past 20 years. Interventional radiologists have developed an important role in the palliative and curative treatment of the disease. This review summarizes commonly used interventional radiological treatment protocols to assist practitioners in understanding the techniques used to treat HCC. METHODS Var...
