Revisiting the Anatomical Landmark-Guided Central Venous Access Device Insertion: A Retrospective Cohort Study.

Abstract

Ultrasound (USG) guidance is superior to blind and open cut-down techniques for accurate puncture of the internal jugular vein (IJV) or subclavian vein, but it increases the cost and duration of the procedure. Here, we report our experience with the reliability and consistency of anatomic landmark-guided technique for Central Venous Access Device (CVAD) insertion in a low-resource setting. A retrospective analysis of the prospectively maintained database of patients undergoing CVAD insertion through one of the jugular veins was performed. Central venous access was achieved using a standardized anatomic insertion landmark (apex of Sedillot's triangle). Ultrasonography (USG) and/or fluoroscopy assistance was taken as and when required. Over 12months (October 2021 to September 2022), a total of 208 patients underwent CVAD insertion. Central venous access was successfully achieved using anatomic landmark-guided technique in all but 14 patients (6.7%), in whom USG guidance or C-arm was used. Eleven out of 14 patients who needed guidance for CVAD insertion had body mass index (BMI) of more than 25, one had thyromegaly while the remaining two had an arterial puncture during cannulation. CVAD insertion-related complications included deep vein thrombosis (DVT) in five, extravasation of chemotherapeutic agent in one, spontaneous extrusion related to a fall in one, and persistent withdrawal-related occlusion in seven patients. Anatomical landmark-guided technique of CVAD insertion is safe and reliable, and can reduce the need for USG/C-arm in 93% of the patients.
