EUROPEAN JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY. Bilateral biliary drainage for malignant hilar obstruction using the stent-in-stent method with a Y-stent: efficacy and complications

Kim, Dong Uk; Kang, Dae Hwan; Kim, Gwang Ha; Song, Geun Am, Kim, Chang Wonb; Kim, Suk; Jang, Ae Lee

Background: The usefulness of bilateral stent placement for malignant hilar obstruction is still under debate. Nevertheless, many endoscopists advocate the placement of an endoscopic bilateral metal stent using various new devices and techniques.

JACC. Renal Sympathetic Denervation Does Not Aggravate Functional or Structural Renal Damage

Oliver Dörr, MD; Christoph Liebetrau, MD; Helge Möllmann, MD; Stephan Achenbach, MD; Daniel Sedding, MD; Sebastian Szardien, MD; Matthias Willmer, MD; Johannes Rixe, MD; Christian Troidl, PhD; Albrecht Elsässer, MD; Christian Hamm, MD; Holger M. Nef, MD

Renal sympathetic denervation (RSD) is an interventional treatment option for resistant arterial hypertension (HT) (1). Previous investigations of RSD excluded patients with progressive chronic kidney disease because of potential RSD-related kidney damage ((1),2). Diagnosis of acute kidney injury is a clinical challenge; because of the absence of clinical symptoms, the diagnosis is based on biomarkers. However, a critical problem is the diagnostic gap for commonly used biomarkers during the early period after acute kidney injury. Highly sensitive biomarkers, such as urinary neurophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule (KIM)-1, are early, maybe even real-time, markers for the early detection of even minor structural and functional kidney damage.

JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY. Transcatheter Arterial Chemoembolization Using Cisplatin Powder Mixed with Degradable Starch Microspheres for Colorectal Liver Metastases after FOLFOX Failure: Results of a Phase I/II Study

JACC: CARDIOVASCULAR INTERVENTIONS. Endovascular Treatment of Resistant and Uncontrolled Hypertension

Matthew C. Bunte, MD; Eduardo Infante de Oliveira, MD; Mehdi H. Shishehbor, DO, MPH

The treatment of resistant hypertension has undergone remarkable advancements in recent years. Endovascular radio frequency renal sympathetic denervation (RSD) has shown initial success in treating resistant hypertension by targeting the connection between the brain and renal sympathetic nerves. However, the encouraging results of first-generation RSD have been tempered by important procedural limitations and a need for long-term results of safety and efficacy. In an effort to build on early clinical success, several second-generation RSD technologies are now being developed that may improve procedural safety and efficacy. Preliminary evidence for some of the latest technologies is now available. In this review, we summarize the current evidence in support of RSD and consider unique features of several new technologies that are likely to refine the endovascular treatment of resistant hypertension.

JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY. Hepatotoxicity after Transarterial Chemoembolization and Transjugular Intrahepatic Portosystemic Shunt: Do Two Rights Make a Wrong?

Maureen P. Kohi, M, Nicholas Fidelman, MD, David M. Naeger, MD, Jeanne M. LaBerge, MD, Roy L. Gordon, MD, Robert K. Kerlan Jr, MD

Purpose: To compare the rates of hepatotoxicity after transarterial chemoembolization for hepatocellular carcinoma (HCC) in patients with and without a transjugular intrahepatic portosystemic shunt (TIPS) who were stratified into comparable risk groups.

JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY. Transjugular Retrograde Cannulation of the Portal Vein via Patent Ductus Venosus: Alternative Access for Endovascular Hepatic Interventions

Ossama Al Masalmeh, MD, Raja Shaikh, MD, Gulraiz Chaudry, MD, ChB, Heung Bae Kim, MD, Steven J. Fishman, MD, Ahmad I. Alomari, MD, MSc

Abstract: The use of the patent ductus venosus via a transjugular approach to access the portal system for endovascular treatment of hepatic vascular anomalies in three infants is reported. Two patients had an arterioportal fistula, and one had a rapidly involuting congenital hemangioma. All patients underwent arteriography followed by embolization of the vascular anomalies without complications. This alternative route is technically simpler and likely safer than transarterial and transhepatic approaches.
