Local ablation therapy is considered as a conventional treatment option for patients with early stage hepatocellular carcinoma (HCC). Although radiofrequency (RF) ablation is widely used for HCC, the use of cryoablation has been increasing as newer and safer cryoablation systems have developed. The thermodynamic mechanism of freezing and thawing used in cryoablation is the Joule-Thomson effect....

BACKGROUND AND PURPOSE Lumbar facet synovial cysts are a cause of back pain and radiculopathy with facet joint degeneration, the most common cause for cyst formation. Typically, LFSCs are T2 hyperintense on MR imaging, but the signal intensity is variable. Treatment options include percutaneous rupture and surgical resection. This study evaluates the relationship between LFSC signal intensity o...

We present a case of successful percutaneous epicardial access in patients with non-ischemic cardiomyopathy limited mapping and ablation the ventricular tachycardia substrate on surface.

BACKGROUND In the advanced stages of hepatocellular carcinoma (HCC), a tumor thrombus (TT) can form in the portal or hepatic vein. The management of patients with advanced HCC and a TT extending into the right atrium (RA) and inferior vena cava (IVC) is extremely difficult and risky. CASE PRESENTATION We report the case of a patient with HCC and a large TT (85 × 45 mm) extending into the RA t...

S6 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 50–85 months) of the 114 patients with CR, only two patients (1.7%) showed cyst recurrence. Based on multivariate analysis, the absence of septa (odds ratio [OR], 7.12; 95% confidence interval [CI], 2.72–18.67) and cyst size <35 mm (OR, 2.39; 95% CI, 1.11–5.16) predicted CR. Conclusion: Among patients with pancreatic cysts who ach...

BACKGROUND Percutaneous epicardial access and mapping/ablation of cardiac arrhythmias are being increasingly performed. Although complications such as pericardial effusion are relatively common, other unusual complications may occur due to the complex anatomic architecture of the heart and surrounding tissues. In this report, we report a series of rare and unusual complications related to percu...

PURPOSE Local thermal ablation may extend the scope of palliative therapy in patients with colorectal liver metastasis. We performed a retrospective, case-controlled study to compare patients with colorectal liver metastases that were treated with percutaneous radiofrequency (RF) or microwave (MW) thermal ablation, against the control group of chemotherapy alone. METHODS We described baseline...

BACKGROUND Percutaneous epicardial mapping and ablation are successful in some patients with ventricular epicardial reentry circuits but may be impossible when pericardial adhesions are present, such as from prior cardiac surgery. The purpose of this study was to evaluate the feasibility of direct surgical exposure of the pericardial space to allow catheter epicardial mapping and ablation in th...

A Saudi man underwent repeated percutaneous aspiration of a pleural effusion before a pleural biopsy showed hydatid disease. Subsequent investigations confirmed hydatid disease in the pleura and liver. The patient underwent surgical evacuation and irrigation of the pleural cavity followed by medical treatment for the liver cyst with albendazole, with complete recovery and disappearance of the l...
