Core Tip

Core Tip: Extra-renal pseudo-aneurysms (EPSAs) are rare post-kidney transplantation, which might be life-threatening and usually need open surgical repair or even nephrectomy. EPSA combined with, or more precisely, caused by transplant renal artery stenosis is rare. There is still no consensus for the treatment of EPSAs. We report the diagnosis and spontaneous healing of an asymptomatic renal allograft EPSA caused by renal artery anastomotic stenosis, which was diagnosed in a timely manner and managed by conservative treatments. The stenosis was relieved after stent implantation, and the EPSA was cured spontaneously by completely filling with hypo-echoic thrombosis 8 mo after stenting.
