Chemoembolization of hepatocellular carcinoma with HepaSphere 30-60 μm. Safety and efficacy study.

Background: This study examined the safety, pharmacokinetics, and efficacy of transarterial chemoembolization of hepatocellular carcinoma (HCC) using a newly developed size of a superabsorbent polymer drug-eluting embolic material.

Methods: Forty-five patients with documented HCC (Child-Pugh score A/B: 55.5 %/44.

Long term recurrence analysis post drug eluting bead (deb) chemoembolization for hepatocellular carcinoma (hcc).

Unlabelled: BACKROUND-AIMS: To determine long term outcomes, regarding recurrence and survival, in patients with HCC that achieved complete response after initial treatment with drug eluting beads (DEB) using DC Bead loaded with doxorubicin (DEB-DOX).

Methodology: Forty-five patients with HCC, not suitable for curative treatments that exhibited complete response (EASL criteria) to initial DEB-DOX treatment were retrospectively analyzed after a median follow up period of 63 months. Child-Pugh class was A/B (62.

Image-guided radiofrequency ablation (RFA) of unresectable hepatic tumors using a triple-spiral-shaped electrode needle: initial experience in 34 patients.

We evaluated the safety and efficacy of image-guided radiofrequency ablation (RFA) using a triple-spiral-shaped electrode needle for unresectable primary or metastatic hepatic tumors. Thirty-four patients with 46 index tumors were treated. Ablation zone, morbidity, and complications were assessed.

Image-guided radiofrequency ablation of a pancreatic tumor with a new triple spiral-shaped electrode.

Image-guided, minimally invasive treatment modalities have become an area of considerable interest and research during the last few years for the treatment of primary and secondary liver tumors. We report our experience with an unresectable pancreatic tumor, treated with application of radiofrequency ablation under CT guidance that even though a complication occurred during the procedure, had excellent results on follow-up CT scans.

Lower gastrointestinal bleeding treated with transcatheter arterial embolization. Case report and review of the literature.

Acute lower gastrointestinal bleeding, is often a dramatic situation, associated with mortality rate up to 28%. Currently transcatheter alternatives have found their place in the therapeutic spectrum of this situation. An interesting question is when should this procedure be performed and which are the difficulties when performing it.

Endovascular stenting for the management of port-a-cath associated superior vena cava syndrome.

Port-a-cath systems are often essential for the administration of long-term chemotherapy in the treatment of malignancies because they improve venous access, but they are associated with complications, mainly thrombosis of central veins. In the present report, we describe a case of right subclavian and superior vena cava port-a-cath-related thrombosis causing superior vena cava syndrome (SVCS) in a patient affected by Hodgkin's disease. The patient underwent percutaneous revascularization with stent positioning, experiencing immediate relief of symptoms.

Patient radiation exposure measurements during interventional procedures: a prospective study.

This is a prospective study with the purpose of assessing patient radiation dose and stochastic risk (risk for fatal cancer) in a patient population undergoing interventional radiological (IR) procedures. Measurements were performed on 36 consecutive patients undergoing percutaneous transluminal angioplasty (PTA, n=18), transjugular intrahepatic portosystemic shunt (TIPS, n=3), diagnostic angiography (DA, n=6), arterial embolization (AE, n=3), and hepatic neoplasm chemoembolization (HCE, n=6). Kerma area product (KAP) was used as a measure of x-ray exposure to the patient.

Evaluation of spiral computed tomography versus ventilation/perfusion scanning in patients clinically suspected of pulmonary embolism.

Objective: To prospectively evaluate the diagnostic accuracy of spiral computed tomography (CT) versus ventilation/perfusion (V/Q) scanning in the examination of patients clinically suspected of having pulmonary embolism (PE).

Patients And Methods: Sixty-three patients, presenting to the emergency department and departments of radiology and nuclear medicine of a large hospital, highly suspected of having PE, underwent sequential imaging testing with V/Q scanning and contrast-enhanced spiral CT, in addition to other clinical and laboratory tests.

Results: PE was diagnosed in 42 (66.

Rare right ventricular myxoma detected incidentally on a FAST examination.

A young man underwent Focused Assessment with Sonography in Trauma (FAST) scan for blunt abdominal trauma. An incidental finding on the pericardial view was the presence of a tumor in the right ventricle. Detailed cardiac imaging and subsequent excision revealed the presence of a myxoma.

Transjugular intrahepatic portosystemic shunt in cavernomatous portal vein occlusion.

A 72-year-old patient with liver cirrhosis and cavernomatous portal vein occlusion presented with refractory ascites. We treated the patient with transjugular intrahepatic portosystemic shunt: transjugular transhepatic puncture of an intrahepatic hilar collateral vein was performed; transjugular intrahepatic portosystemic shunt was created between the right hepatic vein and the patent superior mesenteric vein using this hilar collateral vein as the connecting pathway. The ascites was resolved and the patient remains asymptomatic, while shunt patency is maintained 16 months after the intervention.

Giant adrenal myelolipoma with minimal fat content in a patient with homozygous beta-thalassemia: appearance on MRI.

Giant adrenal myelolipoma is an uncommon entity. We present the atypical MR imaging findings of a giant adrenal myelolipoma in a patient with homozygous beta-thalassemia with histopathology correlation. The tumor showed a drop in signal on the opposed-phase images, with no evidence of macroscopic fat contents, and demonstrated very high signal intensity on T2-weighted images.

Ultrasonographic detection of regional lymph node metastases in patients with intermediate or thick malignant melanoma.

Careful monitoring of regional lymph nodes and early detection of metastases in malignant melanoma patients has an impact on their survival, since it may permit beneficial surgical therapy. Palpation is routinely used in clinical practice. The value of ultrasonography for routine follow-up of melanoma patients, still, is not generally accepted.

Internal iliac artery aneurysm embolization with fibrin sealant: a simple and effective solution.

Endovascular treatment of internal iliac artery (IIA) aneurysms is an attractive alternative to surgical management, because the former is associated with less morbidity and mortality. Embolization with coils or exclusion of the IIA orifice with stent-grafts are the preferred techniques. Although uncommon, technical failures occur with reported aneurysm rupture.

Pancreatitis-associated splenic artery pseudoaneurysm: endovascular treatment with self-expandable stent-grafts.

We present a patient with a splenic artery pseudoaneurysm (SAPA) treated with placement of self-expandable stent-grafts. The procedure was complicated by stent-graft migration, but successful management resulted in lasting exclusion of the SAPA, while the patency of the splenic artery was preserved. This is the first report of self-expandable stent-graft treatment of SAPA.

"Absent" pulmonary artery in one adult and five pediatric patients: imaging, embryology, and therapeutic implications.

Objective: The purpose of this article is to present serial clinical and imaging findings for the "absent" pulmonary artery. Data from six patients with this condition (five unilateral cases and one bilateral case) provide evidence concerning its embryology and illustrate the therapeutic implications of surgical intervention.

Conclusion: In our series, we found the anatomy of the absent pulmonary artery to be consistent with a distal ductal origin and involution of the proximal sixth aortic arch.

Mammographic changes associated with raloxifene and tibolone therapy in postmenopausal women: a prospective study.

Objective: The prolonged use of estrogen therapy is associated with a slightly increased risk of breast cancer. Alternative therapies that are effective in the prevention of menopause, having associated morbidities but no unwanted effects, are of primary interest in the pharmacologic research. The aim of this study was to evaluate the effect of two alternative to estrogens drugs, the selective estrogen receptor modulator raloxifene and the tissue-specific tibolone, on the mammographic appearance of the breast.
