Transarterial embolization of renal cell carcinoma as an adjunctive therapy prior to cryoablation: a propensity score matching analysis

Selective Arterial Embolization with N-Butyl Cyanoacrylate Prior to CT-Guided Percutaneous Cryoablation of Kidney Malignancies: A Single-Center Experience

“…In addition, and in agreement with other reports, no significant change in eGFR after the procedures was found in our study, suggesting that SAE before PCA is safe regarding the renal function [ 5 , 36 , 43 ]. In addition, no complication related to SAE, such as puncture site complication, occurred in our study.…”

“…Embolization significantly decreased complications between size-matched lesions without impacting renal function or recurrence [ 5 ]. This is in contrast with another retrospective study that included 9 patients treated with SAE and PCA and 18 patients treated with PCA alone, in which no significant difference was found in the rate of complications [ 43 ]. However, a comparison of preprocedural and postprocedural hematocrit showed a 2.1 ± 15.4% decrease in the SAE + PCA group versus 9.3 ± 8.3% in the PCA alone group, although the difference did not reach statistical significance ( p = 0.152) [ 43 ].…”

In our study, although a notable proportion of patients were treated with antiplatelet or anticoagulant therapy, only four bleeding events occurred with three small peri-renal hematomas and one larger hematoma, the latter being the only one that required blood transfusion.…”

“…Embolization was repeated the same way in other arteries feeding the tumor that had been previously identified. SAE was considered successful when occlusion of at least one feeding artery was achieved with only partial or no tumor blush upon subsequent angiography and complete SAE was defined as occlusion of all feeding arteries with no residual tumor blush upon subsequent angiography [ 43 ]. Partial tumor blush was mainly due to small feeding arteries either not eligible to microcatheterization or impossible to embolize while preserving adjacent healthy kidney parenchyma.…”

Pneumodissection during Percutaneous Renal Ablation Resulting in Air Embolism: Percutaneous Management and a Review of the Literature

“…Several case series have demonstrated that embolization prior to PA is both safe and technically feasible [16][17][18] ; however, a recent propensity score matching analysis failed to show an objective benefit to the combined approach as it relates to bleeding complications. 19 Both larger retrospective and prospective data are needed to address its clinical utility in either preventing complications or improving oncologic outcomes.…”
