Vacuum for straightening the microcatheter after intra-aneurysmal looping: The "Lagman vacuum" technique.

In many cases, an intra-arterial microcatheter loop is necessary to bypass the neck of wide-necked giant aneurysms for the placement of a stent across it. The removal of this loop is usually challenging, and many techniques have been described to achieve it. We describe a simple novel technique for straightening the microcatheter across the aneurysm's neck, without the need for additional products/devices or complex exchanging techniques. The method has been successfully applied in two cases. We named this novel maneuver the "Lagman vacuum" technique.
