title: Unipuncture double-access method in emergent endovascular procedures.
abstract: We describe a technique to gain an additional endovascular access in acute situations in which a large-bore introducer is already inserted or in situations in which multiple accesses are impaired because of other reasons. Using an existing percutaneous femoral artery access, a second guide wire is inserted into the introducer, which is later withdrawn and applied onto one of the two guide wires. A double-wire access is then achieved. This access can be used, for example, for angiography or embolization catheters. This method might be useful in situations in which a quick and unplanned extra access is needed. It is, for example, applicable in hemodynamically unstable patients in whom percutaneous access can be difficult to obtain or in aortic endovascular procedures when an unplanned access is needed to insert an additional catheter for angiography and embolization.
