A safe percutaneous method to recanalize sharp venous occlusions that resist the passage of guidewires.
It is occasionally necessary to cross a sharp venous occlusion (a thin web of tissue without a lumen) and sometimes it is not possible to cross the stricture with a wire, so puncturing it with a sheathed needle is then required to enable stenting. Other methods have been reviewed; however, we think this balloon technique makes it a safer procedure.
