Amplatzer vascular plug in renal artery embolization: case report and review of the literature

Abstract

Background: Arterial embolization constitutes a safe and effective therapeutic possibility in the treatment of numerous renal pathologies in election and in urgency. Over the years, numerous embolizing materials have been proposed: fibrin (temporary occlusion), glues, coils, and microspheres. The use of St. Jude Amplatzer vascular plug (AVP) constitutes a more recent and less widespread therapeutic choice, and its use in the renal district is not yet widespread although potentially very valid. Case presentation: We present 3 renal arterial embolizations performed with AVP performed between January 2019 and February 2020: two patients had a very bulky renal heteroplastic lesion and were candidates for nephrectomy, and a third patient instead was affected by a high-flow FAV post-biopsy. In our experience, the use of AVP for the treatment of renal arteriovenous fistula and neoplastic masses has given excellent results without any complications during and after the treatment. In all cases, a single plug was used which perfectly adapted to the target artery resulting in complete occlusion of the vessel in a short time. Conclusion: Renal artery embolization performed with AVP has growing potential and numerous advantages in terms of the time of the procedure, speed of embolization, and precision of occlusion, but with a relative increase in costs.

Amplatzer Vascular Plug in Renal Artery Embolization: Case Serial and Review of the Literature

“…This RAE performed with AVP has growing potential and numerous advantages in terms of the time of the procedure, speed of embolization, and precision of occlusion. 14,15 The prospective randomized study showed pre-operative renal artery embolization to be a safe procedure with relatively low complications rate. To our experience, pre-operative renal artery embolization seemed to be a useful tool in surgical management of huge mass and advanced disease.…”

Technical aspect in renal artery embolization in renal tumors: A case series

“…The literature advises obtaining preoperative imaging studies prior to embolization, such as CT scan or MRI, to better identify the unique anatomy and plan the intervention. Laboratory tests comprising of hemoglobin level, renal, cardiac, and hepatic function, and coagulation indexes are also essential [7] .…”

Obstructive oligospermia: the role of interventional radiology in its diagnosis and treatment

“…Treatment of obstructive azoospermia is usually surgical and involves the recovery of sperm through TESE and microTESE techniques. The advantages of interventional vascular radiology that allows minimally invasive treatments of the genitourinary system are described in the literature [ 22 , 23 ]; it allows the diagnosis and treatment of varicocele by endovascular scleroembolization [ 24 ]. However, there are no papers in the literature describing the treatment of obstructive oligozoospermia.…”
