An Unusual Complication in 3 Cases: Renal Subcapsular Hematoma Following Percutaneous Angioplasty

Renal artery stenosis is the leading cause of secondary hypertension. Percutaneous treatment options are safe and effective but can, in rare cases, entail possible complications such as renal subcapsular hematoma. Awareness of such complications will enable better management. Although post-intervention subcapsular hematomas are believed to occur secondary to wire perforation, in this report, we present 3 cases demonstrating reperfusion injury findings rather than wire perforation.
