Abstract
|
|
|
|
Spontaneous renal artery dissection (SRAD) is a rare disease entity. The diagnosis is usually delayed because clinical presentation is non-specific. We report three cases of symptomatic SRAD complicated by renal infarction which occurred in previously healthy middle-aged male patients. They visited the hospital due to acute abdominal or flank pain. They had no specific underlying disease or trauma history. The laboratory tests and physical examination were normal. They were not suspected of having SRAD initially, but computed tomography (CT) revealed dissection of the renal artery with distal hypoperfusion leading to renal infarction. They were treated conservatively with anticoagulation and/or antiplatelets for 6 months. They had a 6-month regular follow-up with CT, where resolution was confirmed in one patient and all patients remained asymptomatic. These cases emphasize the importance of clinical suspicion of SRAD in previously healthy patients who complain of abdominal pain without specific findings on initial investigation.
