Injecting hemostatic matrix in the path of biopsies: efficacy, potential complications, and the management of such complications

Abstract: ObjectiveTo describe the technique of injecting hemostatic matrix, as well as the experience of our interventional radiology department in its application.Materials and MethodsWe conducted a single-center study with retrospective analysis of the experience of our group in the use of hemostatic gelatin matrix in percutaneous biopsies.ResultsIn a total of 73 biopsies in different organs, such as the liver, kidney, and spleen, hemostatic gelatin matrix was introduced into the coaxial needle. The only complication… Show more

“…Other alternatives such as conjugated oestrogens and recombinant human epoietin take between several hours to days to improve platelet function and are thus impractical for use as a prophylactic agent before kidney biopsies 5 . Injection of haemostatic gelatin matrix in the path of the percutaneous kidney biopsy and transjugular biopsies have been proposed for individuals at high bleeding risk, 31,32 but these techniques require specialised skills and lack strong evidence to recommend them. It may be that the absence of good alternatives to prevent post‐biopsy bleeding in at‐risk uraemic individuals prompted the proposed KHA‐CARI guideline to suggest that nephrologists should continue their existing practices, but to be wary of excessive fluid intake should DDAVP be used 12…”

“…Although angiographic techniques are highly effective, non‐angiographic techniques are also effective, and offer a potentially less invasive alternative for preventing hemorrhage‐related morbidity associated with renal or liver biopsy 25 . For example, introduction of hemostatic matrix, such as gelatin matrix, via coaxial needles used for percutaneous kidney and liver biopsies has been reported to be an effective measure to prevent hemorrhage 26 . It has been demonstrated that percutaneous “plugging” of biopsy tracks with PVA foam may help prevent post liver biopsy hemorrhage 27 .…”

“…Due to concerns of hyponatremia [10], further trials are suggested prior to routine usage [11]. In addition, injecting hemostatic matrix in the path of renal biopsies has been used to treat bleeding [12] and to prevent post biopsy bleeding [13].…”
