Abstract:
Renal artery pseudoaneurysm (RAP) is an uncommon but potentially life-threatening condition that is often difficult to diagnose. Rarely, it can occur as a complication associated with a percutaneous renal biopsy procedure. The clinical manifestations vary from asymptomatic lesions found incidentally on imaging studies to a mass causing high blood pressure, pain, haematuria and rupture. Although the risk of rupture is considered low, RAP is associated with a high death rate if ruptured. Currently, with the aid of high-quality interventional radiology, this challenging pathology can be effectively treated. In this report, we describe a case of RAP that was incidentally discovered 4 years after percutaneous renal biopsy which was successfully treated with selective angiographic embolisation.

Blood and Nerve Supply to the Kidney
Bloody Supply to the Kidneys:
The kidneys receive their blood supply from the renal arteries, which branch off from the abdominal aorta—the main artery supplying the abdomen and lower body. The renal arteries enter the kidneys at the hilum, a notch on the medial side of each...
