Femoral neuropathy following venoarterialextracorporeal membrane oxygenation therapy: a case report Albert Youngwoo Jang1, Young Jun Oh2, Seok In Lee3, Oh Kyung Lim4 and Soon Yong Suh1*
Abstract Background: Although life-threatening complications of extracorporeal membrane oxygenation (ECMO) are well described, non-life threatening complications are less known. Herein, we report a case of femoral neuropathy (FN) due to nerve compression caused by cannula compression and deep vein thrombosis (DVT) after successful ECMO therapy, which seriously undermined one’s quality of life. Case presentation: A 70-year old male presented to the emergency department for chest pain. The patient had cardiac arrest before percutaneous coronary intervention (PCI) and was inserted with ECMO. Although he was successfully weaned from ECMO 4 days after PCI, he consistently complained swelling, abnormal sensation, and weakness in his right lower extremity, where the cannulas were inserted. Imaging studies showed deep vein thrombosis (DVT) in his right leg, which was further treated with anticoagulants. Symptoms, however, remained after the regression of DVT. Nerve conduction study revealed femoral neuropathy, which may have been caused by ECMO cannula compression and tissue swelling. Conclusion: The current case proposes that non-life threatening complications of ECMO therapy can seriously affect quality of life. Venous drainage distant from the arterial cannula may prevent such complications. Keywords: Femoral neuropathy, Extracorporeal membrane oxygenation, Case report
Background Extracorporeal membrane oxygenation (ECMO) is a mechanical circulatory supporting device in patients with critical respiratory, cardiac, or combined failure. Due to great survival benefit, more than 24,000 cases of ECMOs were inserted in adults in the United States in 2019, which is approximately 6 times more compared with 2005 [1]. Life threatening neurologic complications, such as stroke, seizure, or intracranial hemorrhage have been reported [2]; however non-life threatening neurologic complications, such as neuropathy associated with ECMO cannulation are less known. * Correspondence: [email protected] 1 Division of Cardiology, Department of Internal Medicine, Gachon University Gil Medical Center, 1198 Guwol-dong, Namdong-gu, 405-760 Incheon, Republic of Korea Full list of author information is available at the end of the article
Herein, we report a case of femoral neuropathy (FN) caused by nerve compression and massive swelling due to deep vein thrombosis (DVT) following ECMO cannulation, which seriously undermined the patient’s quality of life.
Case presentation A 70-year-old male with a history of hypertension, diabetes mellitus, and atrial fibrillation presented to the emergency department with chest pain lasting for 1 hour. The patient did not have any previous neurologic deficits or surgical, family, or genetic history, although he was a heavy smoker (75 pack-years). His initial blood pressure was 109/62 mmHg with a heart r
