SEMINARS IN INTERVENTIONAL RADIOLOGY. Endovascular Management of Chronic Upper Extremity Deep Vein Thrombosis and Superior Vena Cava Syndrome

Charles Wiltrout, M.D. and Kimi L. Kondo, D.O.

Due to medical illness or pharmacotherapy, patients undergoing percutaneous interventions often have abnormal hemostasis. Its etiology may include alterations in the protein-based coagulation system, thrombocytopenia, deficient platelet function, or mixed deficits such as disseminated intravascular coagulation. In this article, the authors review the basic science of each of these etiologies, as well as their available methods of correction. They also review the evidence and guidelines regarding the assessment and treatment of coagulopathy in image-guided procedures. The periprocedural bleeding risk and the urgency of a given procedure guide the management of abnormal hemostasis in this patient population. Semin Intervent Radiol 2010;27:338–347.

SEMINARS IN INTERVENTIONAL RADIOLOGY. Pharmacology of Sclerotherapy

Giustino Albanese, M.D. and Kimi L. Kondo, D.O.

Sclerotherapy is the therapeutic use of sclerosants in the controlled destruction of undesired target tissues. Sclerosants have been used in vascular and nonvascular settings, both as primary and adjunctive therapy. Effective sclerotherapy requires a conceptual understanding of key questions about the process being treated, including the method of delivery, the presence of flow, and the required contact time to initiate sclerosis. However, beyond technique and delivery, practical and safe application of sclerotherapy requires an understanding of the uses, limitations, dosing, and side effects of sclerosants used during interventional radiology procedures. Agents discussed here include detergents and surfactants [ethanol, Sotradecol 1 (Bioniche Pharma, Pointe Claire, Quebec and Angiodynamics, Latham, NY), ethanolamine oleate], hypertonics (saline, glucose), and a review of several other types that are used less frequently.

SEMINARS IN INTERVENTIONAL RADIOLOGY. Chemotherapy Agents: A Primer for the Interventional Radiologist

Frank Mihlon IV, M.D., Charles E. Ray, Jr., M.D. and Wells Messersmith, M.D.

In this article, the authors review the basic principles of cancer chemotherapy and provide an overview of each of the general classes of chemotherapeutic agents with a target audience of interventional radiologists in mind. Special attention is paid to agents used in regional chemotherapy as well as agents commonly included in systemic chemotherapeutic regimens for patients who also require regional chemotherapy.

SEMINARS IN INTERVENTIONAL RADIOLOGY. Prophylactic Antibiotic Guidelines in Modern Interventional Radiology Practice

Eunice Moon MD, Matthew D.B.S. Tam, B.M.B.Ch., M.R.C.S., F.R.C.R., M.A.(Oxon), M.Clin.Ed., Raghid N. Kikano, M.D. and Karunakaravel Karuppasamy, M.B.B.S., F.R.C.R.

Modern interventional radiology practice is continuously evolving. Developments include increases in the number of central venous catheter placements and tumor treatments (uterine fibroid therapy, radio- and chemoembolization of liver tumor, percutaneous radiofrequency and cryoablation), and new procedures such as abdominal aortic aneurysm stent-graft repair, vertebroplasty, kyphoplasty, and varicose vein therapies. There have also been recent advancements in standard biliary and urinary drainage procedures, percutaneous gastrointestinal feeding tube placement, and transjugular intrahepatic portosystemic shunts. Prophylactic antibiotics have become the standard of care in many departments, with little clinical data to support its wide acceptance. The rise in antibiotic-resistant strains of organisms in all hospitals worldwide have forced every department to question the use of prophylactic antibiotics. The authors review the evidence behind use of prophylactic antibiotics in standard interventional radiology procedures, as well as in newer procedures that have only recently been incorporated into interventional radiology practice.

VASCULAR AND ENDOVASCULAR SURGERY. Endovascular Retrieval of Inferior Vena Cava Filter Penetrating Into Aorta: An Unusual Presentation of Abdominal Pain

Louise Yeuk Yan Yeung, MD, Geoffrey Steven Hastings, MD, and Jason Quinn Alexander, MD.

Inferior vena cava filters are commonly used in patients with contraindications to or failures of treatment with anticoagulation. However, these are not without complications. Serious complications include penetration of the filter struts into adjacent structures, including the aorta. The design of permanent filters makes retrieval in the instance of life-threatening complication complex, often requiring extensive surgical exploration. Retrievable filters may be more easily removed via endovascular methods, reducing the morbidity of surgical approaches. Vascular and Endovascular Surgery 44(8) 683-686. Copyright The Author(s) 2010

SEMINARS IN INTERVENTIONAL RADIOLOGY. Review of Pharmacology and Physiology in Thrombolysis Interventions

M. Grace Knuttinen, M.D., Ph.D., Neelmini Emmanuel, M.D., Furquaan Isa, M.D., Alex W. Rogers, Ron C. Gaba, M.D., James T. Bui, M.D. and Charles A. Owens, M.D.

Reperfusion therapy using thrombolytic agents has been shown to be a safe and effective treatment strategy for arterial ischemia, venous thrombosis, massive pulmonary embolism, and acute stroke. Thrombolytic agents have evolved over the course of a few decades, from nonfibrin selective to fibrin-selective agents. The development and modification of these agents have resulted in improved understanding of their pharmacologic attributes, and their effects on the complex molecular events that occur during thrombolysis goal-directed therapies. The current review focuses on the physiology and pharmacology of the thrombolytic agents that have been or are currently in use for interventional thrombolysis interventions. Attention is also given to the particular role that thrombolytic agents play in the current management of peripheral vascular disease and acute stroke. Semin Intervent Radiol 2010;27:374–383.
