Coil embolization of an acutely expanding spontaneous splenic artery dissection

Spontaneous isolated celiac and splenic artery dissection with splenic infarction

Spontaneous isolated celiac artery dissection is considered an uncommon clinical condition. Rarer still is spontaneous isolated celiac and splenic artery dissection, with a total of 42 reported cases. There is no known definitive cause of visceral artery dissections, but risk factors include male sex, age in 5th or 6th decade, hypertension, and connective tissue disorders. The presentation varies, diagnosis is principally radiographic, and the mainstay of treatment is anticoagulation or antiplatelet therapy. Splenic infarction is a common finding with splenic artery dissection, although the strength of this association has not previously been reported. Herein we present a case of spontaneous isolated celiac and splenic artery dissection with splenic infarction that was successfully managed with blood pressure control and antiplatelet therapy. We review previous literature, principles of diagnosis and management, and incidence and outcomes of splenic infarction as it related to splenic artery dissection.

Benefit of vessel closure with the Azur CX Peripheral Coil System in small children with complex CHD

Vessel occlusion is a frequently used procedure to close congenital or acquired collaterals or communications. We report two cases of successful vessel closure, in small infants with CHD, using the Azur CX Peripheral Coil System. The low profile of the device, the controlled delivery of the coils, and the delivery through a microcatheter make it particularly interesting for the occlusion of highly tortuous vessels in children.
