Preoperative vascular mapping increase rate of successful hemodialysis vascular access operation. Several studies recommend using this procedure routinely. But some studies recommend using this procedure in selected patients. So this study aims to determine the impacts of preoperative vascular mapping in unfavorable-examined patients. 55 patients were studied retrospectively from August 2006 to October 2009. Before April 2008, the operative plans were based on physical examination (group 1). After April 2008, the surgeon did preoperative vascular mapping prior to the operation in unfavorable-examined patients (group 2). The results were compared. There were high maturation rates in favorable-examined patients. In unfavorable-examined patients, preoperative vascular mapping can identified nonpalpable favorable vein which successful maturation of 18.75%. Complementary duplex scan decrease rate of unsuccessful operation significantly (p = 0.037) but does not increase maturation rate. Careful physical examination is important part before operation. Preoperative vascular mapping has benefit only in patients with unfavorable-examined patients. It finds some nonpalpable favorable vein and decrease unsuccessful exploration.
