Background: We as spine surgeons increasingly need to carefully screen our own patients for major medical/cardiac comorbidities to determine if they are candidates for spine surgery. Our medical/cardiac colleagues rarely understand how long anti-platelet aggregates and non-steroidal anti-inflammatories (NSAIDs) have to be stopped prior to spine operaeitons, and when it is safe for them to be reinstated. Case Study: A patient over 65 years of age, presented with 6 months of increased bilateral lower extremity sciatica, and 2-block neurogenic claudication. The MR scan showed moderate to severe lumbar stenosis L2-S1 with grade I L4-L5 spondylolisthesis, and multiple bilateral synovial cysts. Nevertheless, his neurological examination was normal. Further, he had > 5 stents placed within the last five years, and had undergone cardiac surgery two years ago requiring placement of a bovine aortic valve, and resection of a left ventricular wall aneurysm. He was also still on full dose Aspirin (325 mg/day), and Clopidogrel (75 mg po bid). Notably, 3 prior spinal surgeons (neurosurgery/orthopedics) had recommended multilevel lumbar laminectomy with instrumented fusions (e.g. including multilevel transforaminal lumbar interbody fusions (TLIF)). Conclusions: Despite multilevel L2-S1 stenosis, Grade I L4-L5 spondylolisthesis, and multilevel bilateral synovial cysts, the patient’s normal neurological examination and multiple cardiac comorbidities (i.e. requiring continued full-dose ASA/Clopidogrel) precluded, in my opinion, offering surgical intervention. Rather, I referred the patient to neurology for conservative management. What would you have done?
