We present a unique case of a 56-year-old female with complex cloacogenic carcinoma history who experienced intraoperative episodes of ventricular tachycardia and pulselessness of unclear etiology. The etiology was later found to be related to a nephroureteral stent that had perforated the right ureter, entered the right ovarian vein, traversed up the inferior vena cava, and nestled in the right atrium.
Keywords: cardiac arrest; cloacogenic carcinoma; nephroureteral stent; ovarian vein; ventricular tachycardia.
