Balloon venoplasty for disdialysis syndrome due to pacemaker-related superior vena cava syndrome with chylothorax post-bacteraemia: A case report

BACKGROUND

Although superior vena cava (SVC) syndrome has also been reported as a late complication of pacemaker (PM) implantation, acute onset of SVC syndrome caused by disdialysis syndrome in patients with PM implantation is very rare. There are no specific therapies or guidelines.

CASE SUMMARY

A 96-year-old woman receiving dialysis was implanted with a PM due to sick sinus syndrome. She was referred to our facility for chest discomfort experienced during dialysis. Upon examination, unilateral pleural effusion on the right side was cloudy with a foul odour. The patient was diagnosed with pyothorax and treated with antibiotics. After the effusion was reduced, it gradually reaggravated and remained cloudy. In this case, SVC syndrome, which is generally considered a late complication after PM implantation, rapidly developed following the bacteraemia, resulting in impaired venous return, chylothorax, and disdialysis syndrome. After catheter intervention for SVC stenosis, the patient's symptoms promptly improved. The patient has been recurrence-free for a year.

CONCLUSION

Acute SVC syndrome can cause dysdialysis in PM-implanted patients. Catheter intervention alone has improved this condition for a traceable period.

Safety of same-day discharge versus overnight stay strategy following cardiac device implantations: a high-volume single-centre experience

BACKGROUND

The strategy of cardiac implantable electronic device (CIED) implantations performed as day-case admissions has gained a wider acceptance overtime; however, data on safety are still limited. This study aims to investigate the safety of a same-day discharge protocol introduced in our hospital for the postprocedural management of patients undergoing CIED implantation.

METHODS

Α prospective, non-interventional, non-randomised study performed in a single high-volume implanting centre for a 16-month period (March 2020 to June 2021). At total of 821 of 965 (85.1%) patients scheduled for elective CIED implantation were considered to be eligible for inclusion in the Short-stay Device Management Protocol. These patients were compared with a historical group of 932 patients, meeting the same inclusion criteria.

RESULTS

Procedure was successful in 812 patients (98.9%), committed to same-day discharge versus 921 of 932 patients (98.8%) admitted for overnight stay (p = 0.87). Overall, 90-day complication rate was comparable in both groups (4.14% vs 4.07%, p = 0.95), as was major (1.46% vs. 1.82%, p = 0.55) and minor (2.67% vs. 2.25%, p = 0.64) complication rates. The composite early post-procedural complication rates and late post-procedural complication rates were comparable among groups (0.97 vs 1.18%, p = 0.70 and 0.73% vs 0.64%, p = 0.83, respectively). Six hundred sixty-seven patients (84%) preferred the same-day discharge strategy. Finally, a reduction of 792 bed-days was recorded, resulting in possible financial Health System benefits.

CONCLUSIONS

Same-day discharge is feasible and safe in the majority of patients referred for CIED implantation. Additionally, same-day discharge is preferred by patients and may reduce procedure-related costs due to significant bed-day reductions.
