Fig. 8.4. a Nonselective celiac angiogram in a patient with a large splenic pseudoaneurysm after trauma. Note the marked vasospasm and contrast pooling in the left upper quadrant, b Coaxial use of a microcatheter to obtain access distal to the neck of the pseudoaneurysm despite the vasospasm, c Follow-up splenic angiogram after coil embolization of the splenic artery. No further contrast extravasation was noted and the patient s vitals stabilized. (Courtesy of James R. Duncan, MD)...

Exophytic tumors - Exophytic tumors can be challenging due to their complex vascular supply. Vascular tumors, especially HCC, can parasitize blood flow from many other sources, such as intercostal arteries, renal and adrenal arteries, as well as the splenic artery. A transcatheter CT angiogram can be performed with the catheter in the vessel of interest. Contrast is injected directly into the catheter while CT images of the liver are acquired, giving an extremely accurate view of contrast distribution [8J. If no extra-tumoral blood flow is seen, one can use this vessel to deliver Y microspheres. 

Fig. 3.10a-d. A large splenic artery false aneurysm is demonstrated near tbe bilum of tbe spleen (a). Tbe 6-F RDC catheter is advanced into tbe orifice of the splenic artery and a microcatheter is passed to the site of injury in the distal splenic artery (b). The microcatheter is advanced distally beyond the site of the communication with the false aneurysm. Micronester coils are placed distal and proximal to the origin of the false aneurysm (c and d) and the final angiogram demonstrates occlusion of the lower pole of the spleen with preservation of the upper pole...
