PURPOSE To describe the appearance of hepatic tumors treated with radio-frequency (RF) ablation on computed tomographic (CT) and magnetic resonance (MR) images and the pattern of residual tumor at the site of RF ablation and to assess prospectively the sensitivity, specificity, and positive and negative predictive CT and MR imaging values in the evaluation(More)
To render hepatectomy feasible in patients with an initially deficient volume of the future remnant liver (FRL), we redistributed portal blood flow rich in hepatotrophic substances toward the FRL. Redistribution was achieved with preoperative portal vein embolization (POPE) feeding the future resected liver. POPE was performed in 31 patients, under(More)
PURPOSE To evaluate the feasibility, complications, adequacy of feeding support, and tolerability of fluoroscopically guided gastrostomy in cancer patients. MATERIALS AND METHODS Five hundred cancer patients were referred for fluoroscopically guided gastrostomy, among whom percutaneous endoscopic gastrostomy was contraindicated or had been unsuccessful in(More)
Two hundred and ninety-one patients with hepatocellular carcinoma were treated by chemoembolization (CE), using ethiodized oil, doxorubicin, and a gelatin sponge. Patients with thrombosis of either the portal vein or a main branch were excluded. The mortality rate in the first 2 months after treatment was 7% in noncirrhotic patients, 2.8% in patients with(More)
PURPOSE To evaluate the feasibility, efficacy, and tolerance of self-expanding metallic stent insertion under fluoroscopic guidance for palliation of symptoms related to malignant gastroduodenal obstruction. MATERIALS AND METHODS Seventy-two patients (38 men, 34 women) aged 25-98 years (mean, 62 years) with duodenal (n = 43), antropyloric (n = 13),(More)
Right portal vein embolization (PVE) was performed in patients in need of wide hepatectomy to induce preoperative hypertrophy of the future remnant liver (FRL), which would have been insufficient for safe resection. PVE was achieved with cyanoacrylate or gelatin sponges by using a percutaneous subxiphoid approach in 10 patients with tumors in noncirrhotic(More)
BACKGROUND/AIMS Lipiodol chemoembolization is a widely used method of treatment in patients with unresectable hepatocellular carcinoma, but its efficacy is still debated. The aim of our study was to assess the efficacy of lipiodol chemoembolization in patients with unresectable hepatocellular carcinoma. METHODS Seventy-three patients with unresectable(More)
OBJECTIVE Our objective was to describe the technical aspects and evaluate the feasibility, safety, and efficacy of endovascular management of mechanical complications related to implanted central venous devices. MATERIALS AND METHODS One hundred fifty-six patients with cancer, who ranged in age from 3 months to 75 years (mean +/- SD, 47 +/- 18 years),(More)
Our objective was to report the outcome in patients with liver metastasis from endocrine tumors who underwent transarterial chemoembolization (TACE) as first-line non-surgical treatment. From January 1990 to December 2000, 14 patients with progressive unresectable liver metastases from digestive neuroendocrine tumor were treated with TACE (mean of 3.6(More)
Dynamic contrast-enhanced ultrasonography (DCE-US) using the contrast agent Sonovue and vascular recognition imaging software is a novel technique that enables the detection of microvessels and quantitative assessment of solid tumor perfusion using raw linear data. Clinical trials have shown that DCE-US can be used to assess the anticancer efficacy of(More)
