Complications of high intensity focused ultrasound in patients with recurrent and metastatic abdominal tumors

Figure 1 CT 2 months before HIFU shows a tumor mass in the upper abdomen (arrow), with the SMA running out from the center (arrowhead).

Figure 2 T1 weighted imaging of MRI 1 wk before HIFU shows a large tumor in the upper abdomen (arrow), with the SMA running out from the center of tumor (arrowhead).

Figure 3 The target tumor presented as a white coagulative necrosis in the exploratory laparotomy 3 d after HIFU (arrowhead), the purple ischemia of the necrotic small intestines are also shown (arrowhead), and the SMA turned out from the center of tumor (arrow).
