Abstract:
Purpose: To evaluate the feasibility of interventional biopsy, the component of stenotic tissues of shunt tract and mechanism of shunt stenosis. Materials and Methods: The pathologic specimens of stenotis shunt tract were obtained in 10 patients with catherization endovascular biopsy clamp and atherectomy methods, then they were undergone routinely with HE stain and immunocytochemical stain, and observed procedures under microscope. Rusults: all of interventional biopsy were succeeded without complication. The microscopies, findcarge of stenotic tissue were primarily composed of fibrotic granulations and thrombi with inflammatory cells and exuberant foam cells derived from endothelial cells, smooth muscle cells and rhagiocrine cells. Conclusion: 1)The interventional biopsy is a safe and effective method. 2)The stenosis in parenchymal tract is related to thrombosis and tissue orangnization.
