Colonic Ischemia, Perforation, and Colectomy after a Complicated Endovascular Embolization for Type II Endoleak with the Use of Cyanoacrylate Glue

one case, postmortem examination revealed a catheter fragment lodged in the valve after the malpositioned catheter had been pulled back at bedside and the tip unknowingly left behind. These events did not result in immediate lethal malfunction; rather, acute alterations in cardiac output eventually progressed to unrecoverable circulatory collapse over the span of 2–5 days. Recognition of catheter or wire entanglement with the artificial valve may allow for immediate retrieval with only transient cardiovascular impairment. It is unclear what the long-term sequelae of such an event would be and whether normal flow dynamics could be restored. This event remains a significant risk that should be mentioned while obtaining informed consent from the patient and during documentation after the procedure. In the right clinical setting, similar transvenous procedures can be offered to patients with a Total Artificial Heart. We chose an A-shaped multipurpose catheter because it is easily torqued and allows directional passage of a wire. This is our standard access catheter for transvenous liver biopsies; however, any similar type of catheter would have sufficed. A stiff exchange wire
