Angiographic Findings and Embolotherapy in Renal Arterial Trauma

Abstract

In hemodynamically stable and controlled patients selective and superselective embolization is a safe and effective method for the management of renal vascular injury.

The role of interventional radiology in trauma

“…Initial haemostasis was achieved in all 43 patients reported in three retrospective series. [22][23][24] Rebleeding occurred in three patients (two of whom were treated with further embolisation), and abscess occurred in one patient. Ultimately, delayed nephrectomy was performed in five of the 43 patients but there were no deaths.…”

The need for early angiography in patients with penetrating renal injuries

“…Embolization of renal vessels results in renal devascularization, and can occasionally lead to renal abscess or even kidney loss. One group reported that 4 of 22 patients (18%) required nephrectomy after renal embolization for trauma [29]. The use of balloon-expandable stent grafts to salvage a kidney after penetrating injury to the renal artery was recently described [30].…”

Spontaneous Perirenal Hemorrhage in End-Stage Renal Disease Treated with Selective Embolization

“…5,6 However, this intervention, especially for the hemodynamically unstable patients, requires experience on the selective and hyperselective embolism with the availability of the proper facilities in the emergency setting. 7 Major complications of the technique are incomplete embolization, coil migration leading to injury of adjacent organs, and postinfraction syndrome including fever, nausea, and vomiting and flank pain. Minor complications include dissection of vessel and groin hematoma, renal intimal dissection, and renal abscess.…”
