Venous-Only Transcatheter Closure: A Safe and Effective Strategy for Patent Ductus Arteriosus

Abstract

Objectives: This study aimed to assess the feasibility and effectiveness of transcatheter device closure of patent ductus arteriosus (PDA) exclusively through an isolated venous route.

Methodology: A retrospective descriptive study was conducted at the Rawalpindi Institute of Cardiology. Patient data from 2019 to 2023 undergoing PDA closure using transcatheter devices were analyzed. PDA diagnosis was established via echocardiography, and the procedure was performed solely through a venous line under fluoroscopy, omitting the traditional method of using both arterial and venous lines.

Results: A total of 212 patients underwent transcatheter PDA closure through a venous-only route, with ages ranging from 6 months to 14 years. The mean weight was 10.07 kg (range: 5 kg to 27 kg, SD 4.43). The average procedure time was 30 ± 10.3 minutes (range: 15.0 to 65 minutes), and fluoroscopy time was 5.4 ± 3.18 minutes (range: 2.1 to 19 minutes). Immediate closure was achieved in all patients, with no residual leaks or device embolization observed. Additionally, there were no reported complications such as arrhythmia, vascular access issues, or significant blood loss. No cases of aortic or pulmonary stenosis were identified, and no deaths occurred. All patients were discharged within 48 hours post-procedure.

Conclusion: Transcatheter closure of PDA exclusively through the venous route, without the use of an arterial line, demonstrates itself as an effective and safe method for PDA closure.
