Cardiovascular implantable electronic device (CIED) has helped with advanced technological improvement in the cardiac field and has been a long-term alternative to medical management. There are different forms of CIEDs such as pacemakers, implantable cardioverter-defibrillators, and cardiac resynchronization therapy. These devices are efficient in establishing near-normal hemodynamics and circulation that ultimately aid physicians to improve the quality of life for their patients. However, there are risk factors that can result in postoperative complications, including infection, lead and pulse generator complications, heart complications, medication-related complications, and psychosocial complications. To ensure optimal outcome of CIED placement, preprocedural measures need to be in place such as matching the right candidate and using appropriate devices. This review aims to highlight the surgical techniques for CIEDs, the associated postoperative complications, and long-term health effects.

Among 716 patients with intracranial blastomatous changes 74 showed diplopia as a consequence of involvement of the oculomotorius, trochlearis or (and) the abducens nerve. Diplopia as primary symptom of disease was observed in 20 cases. Patients with isolated initial diplopia were on average 10 years younger than patients where diplopia occurred only in the further course of the tumour. There were no preceding other diseases demonstrable in patients with initial diplopia. Papilloedema did not occur significantly more frequently in them than in patients with diplopia as secondary symptom. In rare cases latency between occurrence of diplopia and further symptoms may be months to two years. For this reason exact neurologic and ophthalmologic follow-up controls, particularly in young patients with isolated persistent diplopia, are required.
