Selective arterial embolization with gelatin particles for refractory knee hemarthrosis

Recurrent Hemarthrosis Following Knee Arthroplasty Treated with Arterial Embolization

“…The largest series reporting on this procedure, outside of the previous work from our institution, included five patients all of whom had clinical resolution of their symptoms after embolization with gelatin particles [9]. No complications were reported in this group, though one patient did require two procedures because of technical difficulties during the first attempt at embolization.…”

“…If these measures do not resolve the patient's symptoms, an open or arthroscopic synovectomy was the recommended treatment option for a number of years [2,4]. Recently, arterial embolization has been described in a small number of cases as a novel method to treat recurrent hemarthrosis without the morbidity of surgical intervention [5][6][7][8][9]. The goal of this case series is to present the results of 13 consecutive cases of transcatheter arterial embolization for recurrent hemarthrosis after knee arthroplasty.…”

Endovascular management of recurrent hemarthrosis of the knee: a case series

“…Three patients in our cohort underwent embolization with gelatin foam-based slurry (Gelfoam; Pfizer). This was at the discretion of the interventionalist and although successful embolization has been performed using gelatin based embolic agents previously (Yamagami et al 2013 ), this is based on smaller scale trials and we prefer the use of PVA particles due to their more predictable and consistent particle size and non-temporary nature (Sheth et al 2017 ). Calibrated microspheres would be expected to further improve predictable embolic size range due to more tightly calibrated particle sizing.…”
