PURPOSE We aimed to evaluate the effectiveness and safety of percutaneous cryoablation (PC) for early or very early stage hepatocellular carcinoma (HCC) and assess the risk factors for local tumor progression (LTP) after PC. METHODS A total of 45 treatment-naïve patients treated with PC for early or very early stage HCCs were included in this retrospective study. The safety of PC was assessed by evaluating procedure-related complications and comparing hepatic function before and after the procedure. The effectiveness was assessed by evaluating technical success, LTP rates, and disease progression (DP) rates. Prognostic factors associated with LTP after PC were also analyzed. RESULTS Technical success and complete response were achieved in all patients (100%) by 1 month after PC. During a mean of 28.1±15.6 months of follow-up, the incidences of LTP and DP were 11.1% and 37.8%, respectively. The LTP-free and DP-free survival rates were 93.3% and 84.4% at 1 year and 88.9% and 62.2% at 2 years, respectively. Hepatic function was normalized within 3 months after PC. There were no major complications and only one minor complication of small hematoma. On univariate and multivariate analysis, minimal ablative margin less then 5 mm was the only significant risk factor associated with LTP. CONCLUSION PC is a safe and effective therapy for patients with early or very early stage HCC. Minimal ablative margin less then 5 mm was a significant prognostic factor for LTP.PURPOSE We aimed to evaluate the success and failure rates and minor and major complications of percutaneous drainage of retroperitoneal abscesses. METHODS Between 1990 and 2010, percutaneously drained 170 retroperitoneal abscesses in 150 patients (83 males, 67 females, median age 44.2 years, age range, 1-86 years) were included retrospectively. Percutaneous drainage of retroperitoneal abscesses was performed under the guidance of ultrasonography and fluoroscopy or computed tomography. Six abscesses were drained via single needle aspiration whereas 164 abscesses were drained via catheters of 6-14 F calibre using the Seldinger technique. RESULTS When all retroperitoneal abscesses are considered, success rates were found as follows 75.3% cure (128/170), 7.7% temporization (13/170), 4.1% palliation (7/170). Failure rate was 12.9% (22/170). Recurrence rate was 10.6% (18/170), and 13 of the recurred abscesses were treated via second session percutaneous drainage. Mortality rate was 2.7% (4/150). CONCLUSION Percutaneous drainage is the first treatment option for retroperitoneal abscesses due to procedural reliability, elimination of need for general anesthesia, better tolerability, and lower morbidity and mortality rates compared with the surgical methods. High cure, temporization, or palliation rates can be obtained via imaging-guided percutaneous drainage for all retroperitoneal abscesses with a safe access route.PURPOSE We aimed to assess the safety and effectiveness of a modified low-profile hangman technique. METHODS We performed a retrospective review of all filter retrieval procedures performed at a major trauma center, from 2012 to 2019. Records were reviewed for patient demographics, device type, device dwell time, device tilt, embedded hook, success of device retrieval, evidence of caval injury and occurrence of complications. RESULTS From 2012 to 2019 there were 473 filter retrieval attempts. An advanced technique was documented in 66 (14%). The low-profile hangman technique alone was documented in 23 procedures (5% of all procedures, 35% of advanced technique procedures). Average screening time was 28 minutes. At the time of retrieval attempt, 9 patients (41%) were anticoagulated. The hangman technique was employed as isolated maneuver in 23 patients and was successful on initial attempt in 22 cases (96%). The average dwell time of filters retrieved by the hangman technique was 228 days (range, 40-903 days; median, 196 days). No procedure-related complications occurred
