title: [Spontaneous renal artery dissection: a case report].
abstract: A 65-year-old female was admitted to our hospital complaining of left upper abdominal pain. Although the symptom improved with observation, serum creatinine rose to 2.0 mg/dl. Slight atrophy of the left kidney was seen on abdominal plain computed tomography. In order to examine the possibility of renal infarction from thrombosis with angiography, we consulted the department of cardiovascular medicine. Even though we did not detect thrombosis with left renal angiography or intravascular ultrasound, there was a dissection finding localized at the left renal artery. Based on this finding, we made a diagnosis of spontaneous renal artery dissection and performed stent placement. Spontaneous renal artery dissection is extremely rare and the frequency of occurrence is reported to be less than 0.05%. Recently, however the frequency of detection has risen with the development of clinical imaging. We must keep in mind that the condition has the possibility of leading to renal blood circulation disorders.
