Dual-chamber pacemaker implantation can cause total venous obstruction, a complication that was successfully diagnosed with venography and treated with anticoagulant therapy in 2 cases.
Case Report (n=2)
Venous obstruction is a rare but possible complication of transvenous dual-chamber pacing that can be effectively managed with prompt anticoagulant therapy.
Clinicians should consider venography for unexplained symptoms after dual-chamber pacing; case reports leave incidence and optimal management open.
Transvenous endocardial pacing has been widely accepted as an effective means to treat patients with bradycardia, though there are some complications unique to this approach. For example, occlusion of the major vessels can be induced by the presence of a single pacing electrode, though it is an extremely rare occurrence. In this paper, we describe 2 cases of venous obstruction complications caused by dual-chamber pacemaker implantation. Venographic studies were useful to confirm the diagnosis, and immediate anticoagulant therapy resulted in a good course. It is speculated that this phenomenon will increase as physiological, dual-chamber pacing becomes more widely performed. Physicians must pay careful attention to the complication of venous obstruction when managing patients with implanted transvenous dual-chamber pacemakers.

Koike et al. (1988) conducted a case report in Bradycardia (n=2). Dual-chamber pacemaker implantation was evaluated on Venous obstruction. Dual-chamber pacemaker implantation can cause total venous obstruction, a complication that was successfully diagnosed with venography and treated with anticoagulant therapy in 2 cases.
