Abstract

To describe the experience of our institution in image-guided renal nodules percutaneous cryoablation, evaluating demographic and technical aspects as well as efficacy, safety and follow up. Retrospective study approved by our institutional review board. Seventy-one renal tumors evaluated in 60 patients treated with image guided percutaneous renal cryoablation from January 2009 to December 2015. No patient was excluded from study, even those who were lost on follow up. All the procedures were guided both by ultrasound and tomography. An argon and helium based cryoablation machine was used for all treatments. Hydrodissection was performed when the bowel or ureters were within 1 cm (iodinated contrast media in dextrose solution). Complications were assessed by the terminology criteria of the National Institutes of Health (NIH). Patients were monitored and evaluated by ultrasound, tomography, MRI and/or PET-CT. In most procedures (91.9%) only one nodule was treated. Nodules had a median size of 1.6 cm. Most nodules (61,9%) were exophytic. Hydrodissection and retrograde warm pyeloperfusion were performed in most procedures. Among all variables evaluated in univariate analysis, nearness of nodule to collecting system and anterior/po...Continue Reading

Autoimmune Hemolytic Anemia

Autoimmune hemolytic anemia (AIHA) occurs when antibodies directed against the person's own red blood cells (RBCs) cause them to burst (lyse), leading to an insufficient number of oxygen-carrying red blood cells in the circulation. Discover the latest research on AIHA here.
