Key result
Transvenous pacemaker implantation can lead to late complications such as innominate vein thrombosis and subsequent chylothorax, which was successfully treated with talc pleurodesis and angioplasty.
Case Report (n=1)
This case highlights that innominate vein thrombosis can occur as a late complication of transvenous pacemaker implantation and rarely present as a refractory chylothorax.

May prompt evaluation for venous thrombosis in late chylothorax after pacing; single case leaves open incidence and management.
A case of chylothorax following innominate vein thrombosis, which developed as a late complication of transvenous pacemaker implantation, is discussed. A 78-year-old man presented with a refractory left-sided pleural effusion, which turned out to be chylothorax. He had undergone a transvenous pacemaker implantation 6 years earlier for sick sinus syndrome. The aetiological workup showed occlusion of the innominate vein as the cause for the chylothorax. The chylothorax resolved following pleurodesis with talc slurry, and the innominate vein was recanalized by angioplasty. To our knowledge this is the first report of a case of this nature.

Thomas et al. (2005) conducted a case report in Chylothorax following innominate vein thrombosis (n=1). Transvenous pacemaker implantation was evaluated. Transvenous pacemaker implantation can lead to late complications such as innominate vein thrombosis and subsequent chylothorax, which was successfully treated with talc pleurodesis and angioplasty.
