Percutaneous transcatheter embolization is a widely practiced method of minimally invasivetherapeutic vascular occlusion that has been successfully applied to arrest hemorrhagies. Percutaneous transcatheter embolization is defined as the intravascular deposition of an embolic device or agent to produce intentional vessel occlusion. Embolic vascular occlusion may be performed at any arterial level and it may be temporary or permanent. [1] The advantages of transcatheter hemostatic interventions include rapid vascular control, remote access with maintenance of normal tissue barriers, and avoidance of general anesthesia.

We considered seven patients (5 male, mean age 70-yo) treated with cardiological pericardium covered stent for acute visceral bleeding (3 traumatic, 1 iatrogenic), pseudoaneurysm (2 idiopatic) and stenosis with high rupture risk (1 iatrogenic). All patients presented vascular lesion in a not expendable artery. Four patients presented acute hemorrhage signs withanemization and hemodynamicinstability; while 3 were high hemorrhagic risky lesions. All patients presented a vessel diameter between 1.5 and 3 mm with acute hemorrhage or pseudoaneurysm. Vessel involved were: the hepatic artery (Fig. 3 -...

Technical success was achieved in all patients. After a DSA and a superselective angiographic study that demonstrated the bleeding or the pseudoaneurism, seven pericardium covered stent (Aneugraft, Endotech) were released and in three patients coils embolization completed the procedure. The bleeding ceased after stent graftimplantation in all patients and vessel patency was maintained, evaluated with completion angiography. Complete clinical success was achieved withthe resolution of signs and symptoms (restoringhaemodynamicstability). Complete exclusion of the hemorrhage and pseudoaneurysm thrombosis was obtained at following CT control. The mean...

The pericardium covered stent (Aneugraftcovered stent, Endotech) was effective to control acute hemorrhagy avoiding vessel exclusion. Results show pericardium covered stent can be safely used in the treatment of hemorrhages, pseudoaneurysm and small vessel steno-occlusion with good results in terms of complete arterial rupture and pseudoaneurysm exclusion and patency of the stents.
