Postembolization Syndrome

Selective arterial embolization (SAE) for renal angiomyolipoma (rAML) is effective to treat or prevent bleeding. We report our experience using a cyanoacrylate–Lipiodol mixture. We performed a single-center retrospective review of all rAMLs embolized with cyanoacrylate glue between July 2014 and June 2020. Demographics, tuberous sclerosis complex (TSC) status, clinical presentation, angiography features, and follow-up data were recorded. Pre- and post-procedure rAML sizes and volumes were estimated from computed tomography (CT) or magnetic resonance imaging (MRI) studies. Kidney function was assessed before and after the procedure. We identified 24 patients (22 females and 2 males, mean age 51 years) treated for 27 AMLs, either prophylactically (n = 20) or as an emergency (n = 4). Technical success was achieved for 25/27 AMLs; two patients, each with a single AML, required nephrectomy and repeated embolization, respectively. Major complications occurred in three patients and minor complications such as postembolization syndrome in 15 patients. AML volume reduction after embolization was 55.1% after a mean follow-up of 15 months (range, 1–72 months). Factors associated with greater volume reduction were a smaller percentage of fat (p = 0.001), larger initial rAML volume (p = 0.014), and longer follow-up (p = 0.0001). The mean creatinine level did not change after SAE. Embolization of rAMLs with a mixture of cyanoacrylate and Lipiodol is feasible, safe, and effective in significantly decreasing tumor volume.

Objective: To evaluate the efficacy and complications of selective arterial embolization in renal angiomyolipoma and to identify predictive factors for tumor rupture.Materials and Methods: Overall, 21 patients with 25 renal angiomyolipoma (AML) underwent selective arterial embolization (SAE) between January 2008 and June 2019, comprising 15 cases involving prophylaxis embolization of a tumor >4 cm diameter and 10 involving embolization for a ruptured tumor. Multidetector computed tomography (MDCT) was performed pre- and post-SAE, using the 2D tumor diameter in the ruptured AMLs. Three-dimensional volumetry and density histogram were performed for determining the total tumor volume, fat, and angiomyogenic component reduction in the unruptured AMLs. The predictive factors for tumor rupture, the treatment outcome and complications were analyzed. Results: The clinical success rate was 84% (21/25 cases) and the technical success rate was 96% (24/25 cases). The 3D volume post-SAE within 1-3 months showed a greater decrement of the enhanced angiomyogenic component than the fat component, with median percentages of -62.2% and -18.4%, respectively (p-value = 0.333). Minor complications were post-embolization syndrome (5 case, 20%) and minimal renal infarction (4 cases, 16%). Renal abscesses were the major complications (3 cases, 12%). A factor associated with tumor rupture was the presence of an intra-tumoral aneurysm (p-value < 0.05).Conclusion: SAE is an effective treatment for renal AML with a high technical and clinical success rate and limited complications. Three-dimensional volume measurement and density histogram analysis might be better tools than two-dimensional CT to evaluate post-SAE response, which is crucial for management planning.
