Relevant clinical history and physical exam
Case: 48 years-old female.
Clinical history: She was transferred to out hospital because of shock vital caused by malignant hyperthermia.
Her vital sign was fall into the cardiopulmonary arrest immediately on her arrival.
Past history: Schizophrenia
Vital sign on arrival: Cardiopulmonary arrest
Relevant test results prior to catheterization
Relevant catheterization findings
CAG: No fixed stenosis
Mechanical support: VA-ECMO (Arterial cannula; 15Fr from right femoral artery, Venous cannula; 18Fr from right femoral vein)
Treatment by dantrolene could recover the cardiac function and her vital sign, we decided to wean off VA-ECMO at day3.For removal of an arterial cannula, percutaneous access was performed using two Perclose ProGlide devices. First, a 6.0 mm balloon, which was advanced via the sheath of left femoral artery, was inflated at the right common iliac artery for interruption of blood flow. Then, two 0.035-inch coated guide wires through the arterial cannula, the ECMO arterial cannula was removed.Two Perclose ProGlide devices were inserted through the guide wire, and suturing was performed. A 6.0 mm balloon was finally inflated at the suturing point for complete hemostasis. Final angiogram showed no bleeding.
For removal of arterial cannula of ECMO, using with double Perclose ProGlide devices with a balloon could perform complete hemostasis. Because this method is less invasive, we think that this method is useful for patients with severe conditions.
