Selective induction hyperthermia following transcatheter arterial embolization with a mixture of nano-sized magnetic particles (ferucarbotran) and embolic materials: feasibility study in rabbits

APPLICATIONS ENDOVASCULAR EMBOLIZATION FOR PERSISTENT HEMATURIA AT HUE CENTRAL HOSPITAL: NINETEEN CASES SERIES Background: Due to an induced arterio-ureteral fistula is very common after a renal partial surgery, traumatic, biopsy, arteriovenous malformations (AVM), arteriovenous fistulas (AVF). Endovascular interventions include a variety of methods and embolic materials of different circuit nodes for the purpose of completely vascular embolization causing extravasation or reduce the size of the AVM, AVF and False aneurysms, minimizing complications and recurrence. Patient and Method: Nineteen patients were performed the transcatheter arterial embolization (TAE) in Hue central hospital from 10 /2013 to 12 /2018, 19 cases had persistent hematuria. Results: All had excluded extravasation after embolization, no recurrent hematuria. Conclusion: Applications endovascular embolization in persistent hematuria is an effective and safe therapeutic method, it can be widely apply. Keywords: Intravascular intervention, prolonged hematuria

Purpose: Wunderlich syndrome (WS) with hypovolemic shock secondary to ruptured renal angiomyolipoma (rAML) represents an urgent condition. Hence, we reported our experience with transcatheter arterial embolization (TAE) using different embolic materials under this condition.Methods: This retrospective study consisted of 22 patients. Embolic materials including particles, microcoils, and liquid embolic agents were selectively used based on the decisions of interventional radiologists. Technical success was defined as the complete occlusion of bleeding vessels on the final renal angiogram. Clinical success was defined as the absence of re-hemorrhage needed for repeat endovascular or surgery treatment after TAE.Results: The articulated materials were used when WS presented without aneurysms; a combination of particulate materials and microcoils or Glubran 2 alone were used for WS with aneurysms. The technical success based on 24 episodes of TAEs in 22 patients was 100% (24 of 24). Repeat TAE was achieved in two patients with hemorrhages re-occurring two days after the initial embolization with microcoils alone. The clinical success was 90.9% (20 of 22). No nontarget embolization or embolization-related complications occurred during the TAE procedure. Of the patients, 27.3% (6 of 22) experienced minor complications of post-embolization syndrome (PES). During a median follow-up time of 34 months, no recurrent hemorrhage that required repeat endovascular or surgical treatment for hemostasis occurred.Conclusion: Urgent TAE with the selective use of different embolic materials is an effective alternative to control WS with hypovolemic shock secondary to ruptured rAML. The condition of presenting with or without aneurysms may determine the embolic materials employed.
