Partition of Calibrated Tris-acryl Gelatin Microspheres in the Arterial Vasculature of Embolized Nasopharyngeal Angiofibromas and Paragangliomas

Liver/biliary injuries following chemoembolisation of endocrine tumours and hepatocellular carcinoma: Lipiodol vs. drug-eluting beads

“…This may explain why treatment location was close to statistical significance. In our study, we mostly used 500-700 lm DEBs, that probably did not travel deep into the tumour given the size of tumour vessels, which are usually smaller than 300 lm [33]. Therefore, the beads we used might have remained in extra-tumoural vessels and may thus have increased damage to the extra-tumoural liver.…”

Idarubicin-Loaded ONCOZENE Drug-Eluting Embolic Agents for Chemoembolization of Hepatocellular Carcinoma: In Vitro Loading and Release and In Vivo Pharmacokinetics

“…For example, in the PRECISION V study, half of doxorubicin was delivered within 2 mL 300-500 mm DC Bead DEE agents, and the other half was delivered within 2 mL 500-700 mm DC Bead DEE agents (3). There are now arguments to recommend the use of small DEE agents (ie, r 300 mm) for transarterial chemoembolization with DEE agents of HCC because it was shown in a human nonmalignant model that the diameter of intratumoral vessels was o 310 mm (17). In a large study of 237 patients with unresectable HCC comparing the safety of various sizes of DEE agents, smaller diameters (100-300 mm) were not associated with increased complications (18).…”

Elastic characteristics of microspherical embolic agents used for vascular interventional radiology

“…6). The research group lead Laurent has demonstrated the deformable characteristics of microsphere affect clinical consequences because of leading to the different distribution (Laurent et al, 2004(Laurent et al, , 2005(Laurent et al, , 2006. In particular using TGMS, Laurent et al (2004) reported that softer agents were delivered more distally than rigid agents.…”
