Summary
Pacemaker lead-induced venous thrombosis affects 30-45% of patients, often remaining asymptomatic due to collateral circulation. Early recognition and treatment of acute deep venous thrombosis are crucial for reducing complications.
Area of Science:
- Cardiology
- Vascular Surgery
- Medical Device Complications
Background:
- Transvenous pacemaker implantation is common, but venous complications, particularly thrombosis, can occur.
- Pacemaker lead-induced venous thrombosis affects a significant percentage of patients, ranging from 30% to 45%.
Purpose of the Study:
- To review the incidence, clinical features, diagnostic evaluations, and treatments of venous complications after transvenous pacemaker implantation.
- To highlight the importance of recognizing and managing pacemaker lead-induced venous thrombosis.
Main Methods:
- Systematic review of 63 published articles on pacemaker lead-induced venous thrombosis.
- Analysis of data on clinical features, diagnosis, and treatment strategies.
Main Results:
- Venous thrombosis is a common complication, occurring early or late after pacemaker implantation.
- Most chronic cases are asymptomatic due to collateral circulation, but acute thrombosis is often symptomatic.
- Venous obstruction can impact medical therapies and pacemaker lead management.
Conclusions:
- Routine follow-up is essential to identify pacemaker lead-induced venous thrombosis.
- Timely diagnosis and treatment, including anticoagulation, thrombolysis, or venoplasty, are vital to minimize morbidity and mortality.
