Clinical observation of modified lower limb immobilized time after transfemoral cerebral angiography

Abstract

Objective: To explore the feasibility and safety of modified lower limb immobilized time after transfemoral cerebral angiography. Methods: A total of 100 cases of cerebrovascular angiography with modified lower limb immobilized time in the cerebrovascular disease fifth ward of Henan People's Hospital from March 1, 2019 to May 20, 2019 were prospectively collected. The modified lower limb immobilized time was defined as removing the bandage after 4 hours of lower limb immobilized, and getting out of bed to ambulate after 2 hours exercise of the punctured side lower limb on the bed. The primary safety observation indicators included subcutaneous hematoma, pseudoaneurysm, and arteriovenous fistula after lower limb excercise. Secondary safety indicators included puncture point oozing and deep venous thrombosis of the punctured lower limb. Results: All patients had no delayed subcutaneous hematoma, pseudoaneurysm and arteriovenous fistula. There were three other adverse events. One patient had subcutaneous congestion on the puncture side when the elastic bandage automatically released for 2 hours in bed, but the skin was soft and not indurated. The reason for subcutaneous blood stasis may be the spread of subcutaneous hematomas during puncture. The hematoma did not increase after the pressure bandage continued for 2 hours when patients were getting out of bed, and no pseudoaneurysm occurred within 24 hours. One patient developed a small amount of oozing, but no hematoma at the puncture site when the bandage removed after 4 hours of bed rest. No oozing and hematoma formation when patients continued to give another pressure 4 hours. One patient had a small subcutaneous hematoma after the conventional ultrasound, but no visible hematoma was visible to the naked eye. No deep vein thrombosis was found in all patients by ultrasound within 24 hours. Conclusions: It is safe and feasible to ambulate after immobilized the lower limbs for 4 hours and get out of bed for 6 hours after transfemoral cerebral angiography, but it still needs to be confirmed by large number of controlled studies.
