   Abstract 

Resection of giant sacrococcygeal teratoma with high-vasculature in newborns can be a fatal procedure due to massive bleeding of the tumor. Endovascular embolization of the arteries that supply the tumor may lead to minimal blood loss. We present a case of giant high-vascular sacrococcygeal teratoma type-1 that was embolized in an infant born at 35 weeks gestation. This procedure lead to a safe, surgical resection with minimal bleeding: 12 ml.

   Introduction Top


Sacrococcygeal teratoma may be detected antenatally by physical examination and imaging. [1] When sacrococcygeal teratoma has a high vascular component and a diameter exceeding 10 cm, it has a high risk of rupture and consequently profuse bleeding before and especially during surgical resection. [2],[3] We present a case of a giant high-vascular sacrococcygeal teratoma type-1 that was treated with preoperative endovascular embolization prior to its complete surgical resection.


   Case Report Top


A giant high-vascular sacrococcygeal teratoma type-1 was detected in a female fetus by prenatal ultrasound and magnetic resonance [Figure 1]. [1] The patient with the giant sacrococcygeal teratoma (maximum diameter 15.5 cm) was delivered by cesarean birth at 35 weeks gestation, with a weight of 3240 g [Figure 2]. Two hours later, through the left subclavian artery, the patient underwent abdominal aorta angiography. This confirmed the high-vascular tumor supplied by the middle sacral artery and distal vessels from the right internal iliac artery [Figure 3]. All these arteries were embolized distally with gelatin sponges. With the angiographic overlay technique, the embolization of the middle sacral artery was completed with a metallic pushable coil deployed proximally. [2],[3] The final control demonstrated a success ful embolization of the tumor [Figure 4]. Total procedure time was 55 min. The patient received a total of 20 ml of fluids and 6ml of non-ionic contrast medium of concentration of 300 mg/dl (maximum contrast medium dose 2 ml/kg). Consequently, the neonate was transferred from the angiographic suite to the surgical one. The resection of the giant sacrococcygeal teratoma was quite easy because the bleeding was really minimal: only 12 ml. Pathologic evaluation confirmed the teratomatous nature of the tumor.

   Conclusion Top


The feeding arteries of giant high-vascular sacrococcygeal teratoma of a newborn are perfectly identified by an angiography. Preoperative endovascular embolization of the feeding arteries is a safe and effective procedure that leads to a minimal blood loss during the tumor surgical resection.
