Expandable radiofrequency electrodes for ablation of centrally placed hepatocellular carcinoma. Medhat Ibraheem.
ABSTRACT OBJECTIVE To regulate the safety, efficacy, complications, and prognostic factors for survival related to the utilize of expandable radiofrequency (RF) electrodes in the treatment of centrally placed hepatocellular carcinoma (HCC). PATIENTS & METHODS Eighty-six patients with centrally placed single HCC (≤5 cm) undergo RF ablationusing expandable electrode. Therapeutic safety and efficacy were evaluated. Logistic regression analyses of risk factors ... إقراء المزيد

Therapeutic response and risks of radio-frequency in treatment of hepatocellular carcinoma in patients with portal hypertension
ABSTRACT OBJECTIVE To investigate the therapeutic response of radiofrequency ablation for treatment of hepatocellular carcinoma and the consequence of portal hypertension on the survival final results. PATIENTS & METHODS 168 patients with portal hypertension undergo radiofrequency ablation in the act of treatment of HCC (≤5 cm). Therapeutic response and prognostic outcomes were then analyzed. Overall survival was assessed using Kaplan-Meier ... إقراء المزيد

Radiofrequency ablation with monopolar cluster versus bipolar multipolar electrodes for the ablation of ⩾2.5 cm hepatocellular carcinoma
ABSTRACT PURPOSE To compare the effectiveness of radiofrequency ablation using a monopolar cluster and a bipolar multipolar electrode for the ablation of (⩾2.5 cm) hepatocellular carcinoma. METHODS 34 patients with a single HCC (mean size, 4.46 ± 2.3 cm; range, 2.5–7.4 cm) underwent percutaneous RFA with monopolar cluster (n = 18) or bipolar multipolar electrodes (n = 16). Technical success, ... إقراء المزيد

Sonographically Guided Radiofrequency Ablation of Subcapsular Hepatocellular Carcinoma
Abstract Background: Radiofrequency ablation is an important and ideal treatment for hepatocellular carcinoma. However; subcapsular HCC carcinoma need special care to be treated by radiofrequency ablation. Objective: To evaluate the safety and effectiveness of percutaneous radiofrequency ablation (RFA) of subcapsular hepatocellular carcinoma (HCC). Patients and Methods: We performed a retrospective analysis of 50 patients who underwent percutaneous ultrasound-guided RFA for ... إقراء المزيد

Impact of thrombocytopenia on radiofrequency ablation therapy of hepatocellular carcinoma in patients with liver cirrhosis
Abstract Objective: The objective of our study was to assess the impact of thrombocytopenia on percutaneous radiofrequency ablation (RFA) therapy of Hepatocellular carcinoma (HCC) in patients with liver cirrhosis. Material and methods: We analyzed retrospectively 64 patients with liver cirrhosis and thrombocytopenia, defined as a platelet count of less than 100 · 103 /mm3 that had undergone percutaneous RFA to ... إقراء المزيد

2006 | الكلمات المفتاحية Hepatoblastoma Chemoembolizati,
Transarterial chemoembolization in the treatment of hepatoblastoma in children.
Hepatoblastoma is one of the clinical challenges in children, as it is common and frequently unresectable. Chemotherapy can be administered regionally instead of systemically by transarterial chemoembolization (TACE) and thus improve prognosis. The advantages of this technique over systemic chemotherapy led to developing its role from being a palliative or an adjuvant preoperative treatment to being a potentially independent palliative ... إقراء المزيد

2-	Large (>or=5.0-cm) HCCs: multipolar RF ablation with three internally cooled bipolar electrodes--initial experience in 26 patients.
ABSTRACT PURPOSE: To prospectively evaluate the safety and effectiveness of percutaneous multipolar radiofrequency (RF) ablation for the treatment of large (≥5.0 cm in diameter) hepatocellular carcinomas (HCCs). MATERIALS AND METHODS: Twenty-six patients (four women, 22 men; median age, 72 years) with cirrhosis (Child-Pugh class A disease, 22 patients; Child-Pugh class B disease, four patients) and at least one 5.0–9.0-cm-diameter HCC ... إقراء المزيد
