Clinical Outcomes of EVAR and TEVAR in Treating Abdominal and Thoracic Aortic Aneurysms: A Retrospective Study in Indonesia

Abstract

Double lumen catheter (DLC) is a commonly used temporary vascular access in patients with chronic kidney disease (CKD) undergoing hemodialysis. Despite its effectiveness, the use of DLC carries a high risk of emergent complications such as infection, catheter dysfunction, and systemic clinical deterioration. This study aimed to evaluate the clinical characteristics and risk factors associated with emergency DLC insertion at the Provincial General Hospital of West Nusa Tenggara. A retrospective observational study was conducted involving 91 patients who underwent DLC insertion in the emergency operating room (OK CITO) from January to March 2024. Data were obtained from the hospital's procedural registry and analyzed descriptively. The results showed that most patients were male (65.9%) and belonged to adult or elderly age groups. The most frequent site of catheter insertion was the right internal jugular vein (94.5%). The leading risk factors indicating emergency DLC placement included catheter dislodgement (26.4%), catheter dysfunction (17.5%), decreased consciousness (15.4%), and shock (9.9%). These indications were largely related to advanced complications of CKD. The findings highlight the essential role of DLC in urgent clinical scenarios but also emphasize the need for preventive measures through proper catheter care, post-insertion monitoring, and patient education to reduce complications and improve the safety of hemodialysis treatment.
