Not just during puncture, try to avoid mistakes by delivering the Guidewire under fluoroscopy rather than blindly inserting it. If the Guidewire is again sent to the wrong location at this time, it can only be a special situation.
Is there something obstructing the vessel? Arterial occlusion usually occurs in the lower limbs and is unlikely to occur in the upper limbs. Doctors will administer heparin, an interventional surgery requires dual antiplatelet therapy, and what doctors fear most is massive bleeding during the transportation of the Guidewire. If the patient is tense, vascular spasms can also indicate Guidewire jamming, for which doctors routinely administer verapamil and nitroglycerin to slightly relieve such symptoms.
