Liver Lymphatic Imaging and Interventions: Resurrection of the Forgotten Knowledge
Semin intervent Radiol 2020; 37: 318-323 DOI: 10.1055/s-0040-1713638Lymphatic imaging and interventions are gaining wider acceptance as the treatment of various lymphatic diseases. Meanwhile, the liver lymphatic system remains relatively unknown despite its physiological importance. Liver lymph has been at the center of the lymphatic research since the 19th century; however, the acquired knowledge has not been used in clinical research and treatment due to the lack of robust imaging methods. Recently introduced liver lymphangiography and interstitial embolization allow for the diagnosis and treatment of several diseases as...

Complications during Lymphangiography and Lymphatic Interventions
Semin intervent Radiol 2020; 37: 309-317 DOI: 10.1055/s-0040-1713448Lymphangiography as a diagnostic procedure dates back to the 1950s and was widely performed for several decades until being supplanted by other advanced imaging techniques. With the advent of thoracic duct embolization to treat chylothorax, Constantin Cope ushered in a transition from lymphangiography as a diagnostic procedure to a precursor for lymphatic intervention. Subsequently, technical modifications and applications of lymphatic embolization to other medical conditions have greatly expanded the scope and application of lymphangiography and lymphatic...

An Algorithmic Approach to Minimally Invasive Management of Nontraumatic Chylothorax
Semin intervent Radiol 2020; 37: 269-273 DOI: 10.1055/s-0040-1713444Chylothorax is a rare condition characterized by lymph accumulation in the pleural space. When it occurs independent of trauma, it is even more rare and difficult to treat as identification of lymphatic leak is unpredictable. In addition, treatment of this condition with conventional lymphangiography and thoracic duct embolization may not result in positive outcomes. As such, the role of contrast-enhanced dynamic magnetic resonance lymphangiography to guide treatment is key to maximizing success with the advantage of localizing the site of lymphatic leak. ...

Radiofrequency Ablation, Where It Stands in Interventional Radiology Today
Semin intervent Radiol 2019; 36: 398-404 DOI: 10.1055/s-0039-1697945Radiofrequency ablation (RFA) is one of the first developed minimally invasive definitive cancer therapies. The safety and efficacy of RFA is well documented and has led to its incorporation into multiple international societal guidelines. By expanding on the body of knowledge acquired during the clinical use of RFA, alternative ablative technologies have emerged and are successfully competing for locoregional therapy market share. The adaption of newer ablative technologies is leading to a rapid decline in the utilization of RFA by interventional radiolog...

Hepatic Microwave Ablation in Challenging Locations
Semin intervent Radiol 2019; 36: 392-397 DOI: 10.1055/s-0039-1697003In recent years, there has been increased utilization of microwave ablation (MWA) in the treatment of soft tissue tumors. MWA has several theoretical advantages over radiofrequency ablation (RFA) by achieving a more rapid and sustained heating of tissues, increased efficacy in tissues with poor thermal conductivity, and less susceptibility to heat sink effect. While its greater power output has led to appropriate caution when applying this energy to soft tissue tumors, many commonly held beliefs regarding contraindications to MWA are unsupported by data an...

Ethanol Ablation of Neck Metastases from Differentiated Thyroid Carcinoma
Semin intervent Radiol 2019; 36: 381-385 DOI: 10.1055/s-0039-1696651Differentiated thyroid cancer often metastasizes to cervical lymph nodes, characteristically with slow growth rate and low-level aggressiveness. Cervical lymph node resection is the treatment of choice, but ethanol ablation offers a therapeutic option for patients with few nodes unresponsive to radioiodine therapy and who are poor surgical candidates. The ethanol ablation procedure is minimally invasive, guided sonographically, easily and safely repeated, and easily implemented with minimal technology and cost. Transient nerve injury is infrequent and virt...

Interventional Cryoneurolysis: What Is the Same, What Is Different, What Is New?
Semin intervent Radiol 2019; 36: 374-380 DOI: 10.1055/s-0039-1696705Cryoneurolysis is the deliberate application of cold temperatures to nerves for therapeutic purposes. The idea of treating pain with this technique is thousands of years old and has evolved over time through the application of surgical techniques, nerve stimulation and/or landmark guidance, and through device development. Recent integration of the interventional radiology skill set to this space has unlocked a myriad of opportunities—primarily through a unique ability to percutaneously access deep structures in the body with accuracy and precision, a...

Magnetic Resonance –Guided Prostate Ablation
Semin intervent Radiol 2019; 36: 351-366 DOI: 10.1055/s-0039-1697001In 2019, the American Cancer Society (ACS) estimates that 174,650 new cases of prostate cancer will be diagnosed and 31,620 will die due to the prostate cancer in the United States. Prostate cancer is often managed with aggressive curative intent standard therapies including radiotherapy or surgery. Regardless of how expertly done, these standard therapies often bring significant risk and morbidity to the patient's quality of life with potential impact on sexual, urinary, and bowel functions. Additionally, improved screening programs, using prostatic-speci...
