BackgroundSubthalamic Deep Brain Stimulation (DBS) have demonstrated in the last decades to determine an important clinical improvement in advanced and selected Parkinson's disease (PD) patients. However, only a minority of parkinsonian patients meet the criteria to undergo DBS, and the surgical procedure itself is often stressful, especially for patients experiencing severe OFF state. Subcutaneous Apomorphine continuous administration is suitable as an adjunctive therapy capable of improving a suboptimal DBS result. Here we hypothesize a possible role for subcutaneous apomorphine infusion to alleviate severe OFF state in parkinsonian patients undergoing DBS, thus allowing intraoperative microrecording and patient's collaboration during clinical testing.Case presentationA 68-year-old man, suffering from a very long PD-history, characterized by a severe akinetic status and dramatic non-motor features while in OFF, underwent Subthalamic-DBS keeping a slight but continuous apomorphine infusion (1.8 mg/hour), able to guarantee the right degree of patient's collaboration without interfering with microelectrode recordings. There were no intra or perioperative complications and after the procedure he experienced a marked clinical benefit, being able to stop apomorphine administration.ConclusionsHere we described the first Subthalamic DBS procedure performed with a low and stable dopaminergic stimulation guaranteed by subcutaneous Apomorphine continuous infusion. For its rapidity of action and prompt reversibility, apomorphine could be particularly suitable for use during difficult surgical procedures in PD, allowing more therapeutic opportunities for patients who would otherwise be excluded from the DBS option.
