The teaching points of this exhibit are: 1. Etiology and clinical features of various types of renal arteriovenous shunts (rAVSs) 2. The imaging features of rAVSs 3. The classifications of rAVSs 4. The endovascular treatments for rAVSs based on its etiology and angioarchitectures  

A. Etiology and clinical features of rAVSs B. Imaging features of rAVSs • Normal anatomy of renal arteries and veins • Imaging features of rAVSs on CT, MRI and angiography C. Classifications of rAVSs • rAVMs; cirsoid type, angiomatous type, aneurysmal type • Traumatic rAVFs D. Endovascular treatment • Endovascular treatment for rAVSs • Treatment techniques of transcatheter embolization, including selection of embolic materials, catheters, and other adjunctive techniques, based on their types and angioarchitectures Outline The rAVSs is a rare pathological communication between renal arteries and veins, which can cause retroperitoneal hemorrhage, massive hematuria, pain and high-output heart failure. Transcatheter embolization has been accepted as a less-invasive and effective treatment; however it has a risk of complications including renal infarction and pulmonary embolism. For the safe and effective treatment, treatment strategy based on the types and angioarchitectures of rAVFS are mandatory.
