A 61-year-old man was admitted with an exhausted permanent VVI pacemaker, which was implanted 21 years back for a symptomatic intermittent complete heart block. Initial assesments and a pacemaker telemetry revealed acceptable parameters for the existing lead. So a pulse-generator replacement was planned keeping the original lead and the procedure was expected to be simple and uneventful. During the procedure, after the extraction of pulse generator, the old lead was found not to be suitable for connection with the new pulse-generator and no adopter was available to connect them. So it was planned to get a new lead, to be inserted through subclavian venepuncture. However, after getting the venous access there was resistance in lead insertion and the same could not be negotiated. A subclavian venography later revealed total occlusion of the the right innominate vein with collateral circulation [Figure 1]. At this point, the procedure was terminated. The old lead was insulated and kept as such, while a new pacemaker and lead were implanted on the contralateral side [Figure 2]a and b. No further complication occurred and the patient was discharged subsequently in a stable condition.

Venous thrombosis and stenosis at the implantation site are not very uncommon complications after pacemaker placement, with varying incidence in different series. , A study from India revealed diabetes, smoking, hypertension, obesity, previous myocardial infarction, chronic obstructive pulmonary disease (COPD), and congestive heart failure to be more frequently associated with permanent pacemaker-related upper extremity deep venous complications.  In a systematic evaluation of upper extremity deep vein lesions after cardiac device implant, Da Costa et al.  suggested previous use of transvenous temporary leads and a left ventricular ejection fraction less than 40% as independent risk factors to higher incidence of venous lesions 6 months after transvenous pacemaker implant. Advanced age (>65 years), though not qualifying as a risk factor to a higher incidence, encouraged the development of more advanced venous stenosis. In their cohort, some degree of venous lesions were detected in 64% of patients 6 months after transvenous pacemaker implant, but only 5.2% were symptomatic. Therefore, in pacemaker lead replacement procedures, an evaluation of the patency of the subclavian and innominate veins by venography is recommended.  Furthermore, in this manner, the optimal site of puncture can be assessed and possible damage to the already implanted leads could be avoided.
In our case, we did not plan for lead replacement at the onset, but had to go for the same eventually with all the inconvenience thereafter. So, from our experience we strongly recommend routine cineangiography of subclavian vein preoperatively in all the cases of permanent pacemaker lead replacement as well as pulse-generator exchange.
