Description:
The novel DERIVO 2heal Embolisation Device (Acandis, Pforzheim, Germany) is a flexible, fully radiopaque flow-diverter with a fibrin-based nano-coating, which is supposed to make the device inert to the coagulation cascade. We report a case of pseudoaneurysm treatment with this device under single anti-platelet therapy (SAPT). A female patient underwent endoscopic surgery for chronic rhinosinusitis. During surgery, the lateral wall of the sphenoid wall and the adjacent internal carotid artery was injured, leading to massive hemorrhage, which was treated with compression and tamponades. Eleven days after the procedure, the patient developed a rapidly growing pseudoaneurysm at the injury site with a relevant risk of upcoming aneurysm rupture. The aneurysm was treated by implantation of a DERIVO 2heal. A SAPT regimen was chosen due to the recent massive hemorrhage and anticipating enhanced progressive aneurysm occlusion. There were no thromboembolic complications and there was no morbidity. After 5 days, the pseudoaneurysm was completely occluded. The observations of the presented case are promising and warrant further investigation of this device.
