Transjugular intrahepatic portosystemic shunt (TIPS) complications: what diagnostic radiologists should know.

Transjugular intrahepatic portosystemic shunt (TIPS) is an effective therapy for portal hypertension complications and can successfully treat variceal bleeding and refractory ascites. Although TIPS is relatively safe, procedural- or shunt-related morbidity can reach 20%, and procedural complications have a fatality rate of 2%. Delayed recognition and treatment of TIPS complications can lead to life-threatening clinical scenarios.

Percutaneous Trans-Hepatic Embolization of an Iatrogenic Extra-Hepatic Pseudoaneurysm of the Right Hepatic Artery in a Patient With Previous Occlusion of the Proper Hepatic Artery: An Endovascular Procedure to Avoid a Difficult Surgical Repair.

We report a case of successful percutaneous transhepatic, embolization of an iatrogenic extra-hepatic pseudoaneurysm (PsA) of the right hepatic artery (RHA) under combined fluoroscopic and ultrasonographic guidance. A 73-year-old man underwent percutaneous transhepatic biliary drainage placement in another hospital, complicated by haemobilia and development of a RHA PsA. Endovascular embolization was attempted, resulting in coil embolization of the proper hepatic artery, and persistence of the PsA.

Imaging of calcified hepatic lesions: spectrum of diseases.

Hepatic calcifications have been increasingly identified over the past decade due to the widespread use of high-resolution Computed Tomography (CT) imaging. Calcifications can be seen in a vast spectrum of common and uncommon diseases, from benign to malignant, including cystic lesions, solid neoplastic masses, and inflammatory focal lesions. The purpose of this paper is to present an updated review of CT imaging findings of a wide range of calcified hepatic focal lesions, which can help radiologists to narrow the differential diagnosis.

Multidisciplinary approach in the management of uterine intravenous leiomyomatosis with intracardiac extension: case report and review of literature.

Uterine intravenous leiomyomatosis is an uncommon tumor, usually arising from the uterus, with nodular masses which extend intravascularly over variable distances and may reach the inferior vena cava, right atrium, and pulmonary arteries. Early diagnosis and surgical intervention are crucial as intracardiac leiomyomatosis not only causes cardiac symptoms but may result in pulmonary embolism and sudden death. Complete tumor resection is key in disease management, thus rendering cardiac-extending uterine intravenous leiomyomatosis one of the most challenging conditions for surgical treatment.

Peripheral Artery Disease and Continuous Flow Left Ventricle Assist Device: An Engaging Complement Analysis May Help to Guide Treatment.

Use of continuous flow left ventricle assist device (CF-LVAD) in advanced heart failure (HF) patients results in clinically relevant improvements in survival, functional capacity, and quality of life. Peripheral artery disease (PAD) can occur in patients with CF-LVAD due to the high rate of concomitance between risk factors for atherosclerosis and HF. Diagnosis of PAD can be difficult in the specific setting of a patient supported by this kind of device because of the marked alteration in waveform morphology and velocity created by the artificial physiology of an LVAD.

Intrahepatic mass-forming cholangiocarcinoma: enhancement pattern on Gd-BOPTA-MRI with emphasis of hepatobiliary phase.

Purpose: To describe the Gd-BOPTA MRI findings of intrahepatic mass-forming type cholangiocarcinomas (IMCs), with emphasis on the hepatobiliary phase (HBP).

Methods: We reviewed retrospectively 29 IMC patients who underwent Gd-BOPTA-MRI between June, 2004 and June, 2014. Images were acquired prior to, and after, administration of 15-20 mL of Gd-BOPTA in the dynamic phase (arterial phase, portal venous phase, and 3-5 min phase), 10-15-min late phase, and 2-3 h HBP phase.

Natural course of extrahepatic nonmalignant partial portal vein thrombosis in patients with cirrhosis.

Purpose: To define the natural course of extrahepatic nonmalignant partial portal vein thrombosis (PVT), including the progression from partial to complete PVT, in patients with cirrhosis who had undergone multidetector computed tomography (CT).

Materials And Methods: This study was institutional review board and ethics committee approved. Written informed consent was obtained for each procedure.

Imaging findings of colonic wall redundancy in cystic fibrosis patients: two case reports.

Colonic wall redundancy (CWR) is a condition often seen in adult cystic fibrosis patients, but the imaging features of this condition are poorly described in the literature. Recognizing the radiological presentation of CWR is important because this condition can be confused with acute or acquired colonic diseases that can require specific treatment. We present two cases of CWR evaluated with ultrasound, 64-multidetector CT scan, and magnetic resonance.

Multidisciplinary imaging of liver hydatidosis.

Liver hydatidosis is a parasitic endemic disease affecting extensive areas in our planet, a significant stigma within medicine to manage because of its incidence, possible complications, and diagnostic involvements. The diagnosis of liver hydatidosis should be as fast as possible because of the relevant complications that may arise with disease progression, involving multiple organs and neighboring structures causing disruption, migration, contamination. The aim of this essay is to illustrate the role of imaging as ultrasonography (US), multi detector row computed tomography, and magnetic resonance imaging (MRI) in the evaluation of liver hydatidosis: the diagnosis, the assessment of extension, the identification of possible complications and the monitoring the response to therapy.

Thoracic complications following lung transplantation: 64-MDCT findings.

The aim of this review is to present the wide spectrum of common and uncommon thoracic complications that can affect the lung after transplantation. These complications were analyzed using 64 multi-detector row helical CT (MDCT). Sixty-four MDCT techniques and parameters are illustrated.

Complex hydatid cysts of the liver: a single center's evolving approach to surgical treatment.

In our study, we arbitrarily define complex hydatid cysts of the liver as either cysts with a diameter > or =10 cm, or as multiple and recurrent cysts. These types of cysts were then divided into two subgroups: giant cyst identified as a cyst with a diameter > or =10 cm, and complicated cyst as multiple, recurrent, abscessed cysts, or those resistant to conservative treatment. The aim of this study was to retrospectively analyze a series of 38 consecutive patients who underwent surgery for complex hydatid cysts over a period of 9 years at the same institute to determine the evolution of the surgical treatment and the risk factors for recurrence.
