PURPOSE The authors report their experience treating progressive liver metastases from carcinoid tumor with doxorubicin, iodized oil, and gelatin sponge embolization. MATERIALS AND METHODS Of 23 patients, 18 had carcinoid syndrome and 19 had elevated urinary 5-hydroxyindoleacetic acid (5-HIAA) levels. Relief of symptoms, changes in 5-HIAA levels, and(More)
OBJECTIVE We evaluated the feasibility, tolerance, and efficacy of percutaneous hepatic vein or segmental portal branch balloon occlusion during radiofrequency ablation of hepatic malignancies. SUBJECTS AND METHODS Ten tumors were treated by percutaneous radiofrequency ablation during balloon occlusion of a hepatic vein (n = 8) or a segmental portal(More)
Our goal was to determine a subset of patients at high risk of developing liver abscesses after local treatment of liver tumors (LTLT) and establish guidelines for the conduct of LTLT in the safest conditions in such patients. Five hundred sixty-one LTLT, 489 transhepatic arterial chemoembolizations (TAC, 10 hepatic embolizations, and 62 percutaneous(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)
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)
BACKGROUND Some patients cannot undergo curative surgical procedures for liver metastases because of the risk of severe postoperative hepatic failure, which stems from a too-small future remaining liver (FRL). Preoperative portal vein embolization (PVE) is an effective means of creating hypertrophy of the FRL, thus permitting safe hepatic resection. The aim(More)
AIM To investigate intra-operator variability of semi-quantitative perfusion parameters using dynamic contrast-enhanced ultrasonography (DCE-US), following bolus injections of SonoVue(®). METHODS The in vitro experiments were conducted using three in-house sets up based on pumping a fluid through a phantom placed in a water tank. In the in vivo(More)
OBJECTIVE The aim of our study was to confirm the value of high-frequency and color Doppler sonography in evaluating the metastatic potential of melanomas. SUBJECTS AND METHODS Sixty-nine histologically proven melanomas in 67 patients were prospectively studied before surgical resection. A morphologic study was performed with a 20-MHz probe. The maximal(More)
INTRODUCTION The aim of this study was to determine the efficacy of Doppler ultrasonography (US) with perfusion software and contrast agent injection (DUPC) during radiofrequency (RF) treatment of local recurrent breast cancer. MATERIALS AND METHODS Ten patients were included in this monocentric prospective phase II study. DUPC was performed for each(More)
OBJECTIVE The objective of our study was to evaluate the efficacy and safety of radiofrequency ablation of hepatic metastases performed either percutaneously for treatment of hepatic metastases in patients deemed ineligible for surgery or intraoperatively during partial hepatectomy to destroy unresectable metastases. SUBJECTS AND METHODS Sixty-eight(More)
