OBJECTIVE. The purpose of our study was to assess the relationship between time intervals of CT examinations and the stages of hepatocellular carcinomas (HCCs) detected during the surveillance of patients with liver cirrhosis.
Purpose: To evaluate the feasibility and safety of magnetic resonance (MR) imaging–controlled transurethral ultrasound therapy for prostate cancer in humans.
OBJECTIVE. The purpose of this study was to evaluate a new imaging technique for the assessment of breast cancer tumor margins. The technique entails deployment of a high-resolution optical imaging needle under ultrasound guidance. Assessment was performed on fresh ex vivo tissue samples.
Living donor liver transplant (LDLT) is a major surgical undertaking. Detailed pre-operative assessment of the vascular and biliary anatomy is crucial for safe and successful harvesting of the graft and transplantation. Computed tomography (CT) and magnetic resonance imaging (MRI) are currently the imaging modalities of choice in pre-operative evaluation. These cross-sectional imaging techniques can reveal the vascular and biliary anatomy, assess the hepatic parenchyma and perform volumetric analysis. Knowledge of the broad indications and contraindications to qualify as a recipient for LDLT is essential for the radiologist reporting scans in a pre-transplant patient. Similarly, awareness of the various anatomical variations and pathological states in the donor is essential for the radiologist to generate a meaningful report of his/her observations. CT and MRI have largely replaced invasive techniques such as catheter angiography, percutaneous cholangiography and endoscopic retrograde cholangiopancreatography. In order to generate a meaningful report based on these pre-operative imaging scans, it is also mandatory for the radiologist to be aware of the surgeon’s perspective. We intend to provide a brief overview of the common surgical concepts of LDLT and give a detailed description of the minimum that a radiologist is expected to seek and report in CT and MR scans performed for LDLT related evaluation.
Background—Catheter-based renal sympathetic denervation (RDN) reduces office blood pressure (BP) in patients with resistant hypertension according to office BP. Less is known about the effect of RDN on 24-hour BP measured by ambulatory BP monitoring and correlates of response in individuals with true or pseudoresistant hypertension.
AIM: To perform a meta-analysis of palliative stent placement vs palliative surgical decompression for management of incurable malignant colorectal obstructions.
AIM: To investigate the clinical advantages of the stent-laparoscopy approach to treat colorectal cancer (CRC) patients with acute colorectal obstruction (ACO).
Primary liver cancer and liver metastases are among the most frequent malignancies worldwide, with an increasing number of new cases and deaths every year. Traditional surgery is only suitable for a limited proportion of patients and imaging-guided percutaneous thermal ablation has achieved optimistic results for management of hepatic malignancy. This synopsis outlines the first clinical practice guidelines for ultrasound-guided percutaneous microwave ablation therapy for hepatic malignancy, which was created by a joint task force of the Society of Chinese Interventional Ultrasound. The guidelines aim at standardizing the microwave ablation procedure and therapeutic efficacy assessment, as well as proposing the criteria for the treatment candidates.
Hepatocellular carcinoma (HCC) represents one of the most common neoplasms worldwide. Surgical resection and local ablative therapies represent the most frequent first lines therapies adopted when liver transplantation can not be offered or is not immediately accessible. Hepatic resection (HR) is currently considered the most curative strategy, but in the last decade local ablative therapies have started to obtain satisfactory results in term of efficacy and, of them, radiofrequency ablation (RFA) is considered the reference standard. An extensive literature review, from the year 2000, was performed, focusing on results coming from studies that directly compared HR and RFA. Qualities of the studies, characteristics of patients included, and patient survival and recurrence rates were analyzed. Except for three randomized controlled trials (RCT), most studies are affected by uncertain methodological approaches since surgical and ablated patients represent different populations as regards clinical and tumor features that are known to affect prognosis. Unfortunately, even the available RCTs report conflicting results. Until further evidences become available, it seems reasonable to offer RFA to very small HCC (< 2 cm) with no technical contraindications, since in this instance complete necrosis is most likely to be achieved. In larger nodules, namely > 2 cm and especially if > 3 cm, and/or in tumor locations in which ablation is not expected to be effective or safe, surgical removal is to be preferred.
AIM: To evaluate clinical outcomes of patients that underwent surgery, transarterial embolization (TAE), or supportive care for spontaneously ruptured hepatocellular carcinoma (HCC).
AIM: To evaluate the clinical efficacy of an expanded polytetrafluoro-ethylene-covered Fluency stent compared with that of a polyethylene terephthalate-covered Wallgraft stent for the management of transjugular intrahepatic portosystemic shunt (TIPS) dysfunction.
Objectives The aim of this prospective randomized study was to assess the impact of renal artery denervation in patients with a history of refractory atrial fibrillation (AF) and drug-resistant hypertension who were referred for pulmonary vein isolation (PVI).
OBJECTIVE. Thromboembolic disorders are leading causes of morbidity and mortality, with treatment and prophylaxis a priority. There has been a heavy dependency upon warfarin and heparin for anticoagulation for 60 years. This is likely to change with the emergence of novel oral anticoagulants.
OBJECTIVE. The objective of our study was to assess outcomes after evaluation of immature hemodialysis arteriovenous fistulas (AVFs) via 3-French brachial artery access and to identify the incidence of arterial and venous puncture site spasm.
OBJECTIVE. The purpose of this study is to determine a concentration of iodinated contrast media in saline and 5% dextrose in water (D5W) for organ hydrodissection, a technique used to physically separate and protect tissues adjacent to thermal ablations.
