  • Title: [Intravascular stents for treatment of systemic venous obstructions].
    Author: Schranz D, Michel-Behnke I, Schmid FX, Oelert H.
    Journal: Z Kardiol; 1996 Jul; 85(7):477-81. PubMed ID: 8928545.
    Abstract:
    Two young adults, 16 and 18 years of age were admitted with complete occlusion of the superior vena cava pathway following previous Mustard procedure. In both patients, perforation of complete occluded vein segment using a straight guidewire and subsequent sequential enlargement by balloon dilation were successfully performed by a left subclavian vein approach. Implantation of a 30 mm Palmaz-stent resulted in a widely patent channel of the vena cava superior into the systemic venous atrium. In short-term follow-up of 3 months both stents remained patent. Repeat dilation of the stents was performed after 3 months. A third patient with systemic venous obstruction was a 3-year old child who suffered low cardiac output following modified Fontan operation caused by a narrowing of the superior vena cava to right pulmonary artery connection and stenosis of distal left pulmonary artery. The severe hemodynamic problem was resolved by implantation of Palmaz-stents in the two separate obstructions. At recatheterization 6 months later, both stents were patent without any residual pressure gradient.
