In traumatic bleeding in the area of the liver, haemostasis may be performed within the framework of diagnostic arteriography by means of embolization. Arterial access likewise facilitates embolization and cytostatic treatment of liver tumours (following angiographic insertion of the catheter), (s. tab. 8.4)... 

Fig. 7.6a-c. Planar scintigraphy shows a focal high uptake area that could be interpreted as tumoral (a). Fusion images demonstrate that the uptake is placed outside the liver, in a vascular structure (b). A retrospective review of the angiographic images shows contrast accumulation, thus also MAA accumulation in a vascular stump located between the catheter and the coils (c)...

Typically the procedure starts with a 5-F angiographic catheter which is used to select the main trunk of the visceral artery. This is used both for performance of the diagnostic arteriogram as well as to provide a conduit to direct the microcatheter into the visceral artery. The choice of the initial 5-F catheter depends greatly on personal preference but also depends on the particular shape of the target artery the target artery. 

Arterial vasospasm is the most common complication associated with passage of the guidewire and catheter into the uterine artery. Because of its diameter and tortuosity, the uterine artery is prone to spasm. In theory, embolization of an artery in spasm may not result in a lasting occlusion since relaxation of the vessel can increase luminal diameter enough to allow flow around the embolization particles [2], This may lead to a false angiographic end-point with secondary redistribution of the embolization particles [2, 10]. The systematic use of microcatheters and microguidewires has been shown to minimize the occurrence of spasm and medications such nitroglycerin or papaverine maybe effective to treat spasm [2].
