Interventional therapy of vascular complications caused by the hemostatic puncture closure device angio-seal (see comments)

摘要

The hemostatic puncture closure device Angio-Seal is a quick, safe, and easy-to-use system, allowing rapid sealing of the vascular access site following coronary angiography and interventional procedures. It is advantageous for patients in whom early mobilization is desired and may therefore decrease hospital costs. Despite the documented low complication rate, there are some specific problems. Reporting on five cases, we describe problems in diagnosis and possible interventional therapy of Angio-Seal-associated complications such as stenosis, occlusion, or peripheral embolism. Our experience led to the concept of precise diagnosis in any patient with leg symptoms and early interventional treatment with the aim of complete removal of the intra-arterial parts of the Angio-Seal device. Any delay in diagnosis and treatment increases the risk of additional thrombotic occlusion. Spontaneous dissolution of the Angio-Seal sponge limits interventional possibilities of complete removal.
