Benjamin Jacobs, Chandu Vemuri
Nanoparticles, structures of less than 200 nm capable of delivering pharmacotherapeutics to sites of disease, have shown great promise for the treatment of many disease states. While no nanoparticle therapies for deep vein thrombosis are currently approved by the Food and Drug Administration, many of the unique features of these therapies have the potential to treat both deep vein thrombosis and its most significant sequela, postthrombotic syndrome, while limiting the hemorrhagic complications of current antithrombotic therapies...

The postthrombotic syndrome (PTS) is a frequent cause of long-term disability in patients with lower extremity deep vein thrombosis. A broad variety of interventions have been applied to patients with established PTS, including lifestyle, medical, compressive, endovascular, and open surgical therapies. However, the volume of evidence to support many individual elements of care is sparse, and important questions remain that must be answered to enable judicious individualization of PTS care. The purpose of this article is to describe what is known about PTS care elements and to identify important evidence gaps that merit future studies...

Deep vein thrombosis (DVT) is a prevalent disease. About 20 to 30% of patients with DVT will develop postthrombotic syndrome (PTS) within months after the initial diagnosis of DVT. There is no gold standard for diagnosis of PTS, but clinical signs include pitting edema, hyperpigmentation, phlebectatic crown, venous eczema, and varicose veins. Several scoring systems have been developed for diagnostic evaluation. Conservative treatment includes compression therapy, medications, lifestyle modification, and exercise...

REVIEW
Timothy A Carlon, Deepak Sudheendra
Approximately 10% of all deep vein thromboses occur in the upper extremity, and that number is increasing due to the use of peripherally inserted central catheters. Sequelae of upper extremity deep vein thrombosis (UEDVT) are similar to those for lower extremity deep vein thrombosis (LEDVT) and include postthrombotic syndrome and pulmonary embolism. In addition to systemic anticoagulation, there are multiple interventional treatment options for UEDVT with the potential to reduce the incidence of these sequelae...

REVIEW
Resmi Ann Charalel, Suresh Vedantham
The presence of cancer increases the risk of deep vein thrombosis (DVT), DVT recurrence, and treatment-related bleeding, and therefore offers distinctive clinical considerations when planning treatment. Anticoagulation with a low-molecular-weight heparin is the preferred initial and long-term therapy in cancer patients. Inferior vena cava filters may be used judiciously for patients with cancer-related DVT who have contraindications to anticoagulation or who exhibit breakthrough pulmonary embolism (PE) despite anticoagulation, but should be removed when the PE risk is felt to subside...

Over the past two decades, the incidence and recognition of venous thromboembolism (VTE) in children has significantly increased, likely as a result of improvements in the medical care of critically ill patients and increased awareness of thrombotic complications among medical providers. Current recommendations for the management of VTE in children are largely based on data from pediatric registries and observational studies, or extrapolated from adult data. The scarcity of high-quality evidence-based recommendations has resulted in marked variations in the management of pediatric VTE among providers...

REVIEW

Cavoatrial deep venous thrombosis (DVT) is diagnosed with increasing prevalence. It can be managed medically with anticoagulation or with directed interventions aimed to efficiently reduce the thrombus burden within the target venous segment. The type of management chosen depends greatly on the etiology and chronicity of the thrombosis, existing patient comorbidities, and the patient's tolerance to anticoagulants and thrombolytic agents. In addition to traditional percutaneous catheter-based pharmacomechanical thrombolysis, other catheter-based suction thrombectomy techniques have emerged in recent years...

REVIEW
Christopher Kabrhel
Pulmonary embolism response teams (PERTs) have recently been developed to streamline care for patients with life-threatening pulmonary embolism (PE). PERTs are unique among rapid response teams, in that they bring together a multidisciplinary team of specialists to care for a single disease for which there are novel treatments but few comparative data to guide treatment. The PERT model describes a process that includes activation of the team; real-time, multidisciplinary consultation; communication of treatment recommendations; mobilization of resources; and collection of research data...

There has been a resurgence of interest in defining the optimal treatment for severe pulmonary embolism (PE), fueled by pivotal and provocative trials, new catheter-based medical devices, and growing evidence of deleterious short- and long-term outcomes. In this environment, and especially given the multidisciplinary nature of PE care, the interventional radiologist (IR) needs to become an astute, disease-specific expert. This review article describes the following "steps" an IR can take to reach this level: (1) understand PE stratification and epidemiology; (2) recognize the treatment goals for massive PE; (3) recognize the wide range of attitudes toward therapeutic escalation for submassive PE; (4) recognize what we do not know about the treatment of submassive PE and the limitations of current studies; (5) know the literature surrounding inferior vena cava filter insertion for severe PE; (6) integrate into the longitudinal care of the patient; and (7) be at the leading edge of new trials and technologies...

Several new oral anticoagulants have recently been approved for the treatment of venous thromboembolism (VTE). In this review, we discuss the currently approved drugs and the factors that influence the choice of anticoagulant in a given patient. Once anticoagulation is initiated, periodic monitoring of adequacy of anticoagulation may be necessary depending on the choice of anticoagulant and patient-related factors, such as renal function. Situations that may warrant need for monitoring and the tests available for this purpose are discussed...

Biliary obstruction occurs in a wide variety of malignant and benign conditions. The following is a unique case of biliary obstruction caused by external compression of the hepatic duct by a gallstone (Mirizzi syndrome). Owing to unusual imaging characteristics of the stone, the mass was initially mistaken for a malignancy or hepatic pseudoaneurysm. It was not until the patient developed gallstone ileus that the correct diagnosis was made.

REVIEW
Rakesh Navuluri
Hemobilia is a rare source of upper gastrointestinal bleeding, though the incidence is increasing along with the rise in minimally invasive biliary interventions. Prompt diagnosis and treatment rests on having appropriate clinical suspicion which should be based on the patient's presenting signs and symptoms, as well as history including recent instrumentation. Endoscopy should be reserved for cases of upper gastrointestinal bleeding with low suspicion for hemobilia. Interventional radiology may be the first-line diagnostic and therapeutic option for patients with a high suspicion of hemobilia...

Biliary disease in infants and children frequently presents diagnostic and therapeutic challenges. Pediatric interventional radiologists are often involved in the multidisciplinary teams who care for these patients. This article reviews several notable causes of biliary disease in children who have not undergone liver transplantation, describes the role of percutaneous interventional procedures in managing these conditions, and details applicable biliary interventional techniques.

Postoperative biliary leaks have become more common in the past three decades since the development of laparoscopic biliary surgery. The role of the radiologist and interventional radiologist is important in the diagnosis and treatment of such complications, and can play an adjunctive role in the definitive surgical repair. Ultrasound, computed tomography, magnetic resonance cholangiopancreatography, nuclear medicine cholescintigraphy studies, and percutaneous transhepatic cholangiograms (PTC) are the various imaging modalities used for diagnosis...

REVIEW
Ashley Altman, Steven M Zangan
Differentiating benign and malignant biliary strictures is a challenging and important clinical scenario. The typical presentation is indolent and involves elevation of liver enzymes, constitutional symptoms, and obstructive jaundice with or without superimposed or recurrent cholangitis. While overall the most common causes of biliary strictures are malignant, including cholangiocarcinoma and pancreatic adenocarcinoma, benign strictures encompass a wide spectrum of etiologies including iatrogenic, autoimmune, infectious, inflammatory, and congenital...

REVIEW
Karan Gulaya, Shamit S Desai, Kent Sato
The role of percutaneous cholecystostomy (PC) in the management of acute cholecystitis and cholangitis is outlined in the revised 2013 Tokyo Guidelines. These two emergencies constitute the vast majority of PC performed today for therapeutic purposes, and research has repeatedly shown the utility of PC in these conditions. PC is typically employed in the management of critically ill patients who are not surgical candidates. Indications and contraindications to PC are reviewed. Additional innovative applications of PC have been developed since it was first described in 1980...
