Neurovascular devices, though not technically part of neurosurgery, play a huge role in allowing patients to mitigate and recover from oftentimes life-altering conditions in the brain. This month, we’re putting the spotlight on the neurovascular devices market – and breaking down the medical conditions, reimbursements, companies, and brands for healthcare supply chain professionals.
The neurovascular discipline deals with the vasculature system within the cranium (head). Stroke is the most common neurovascular issue treated according to Medicare Severity-Diagnosis Related Group (MS-DRG) counts. Strokes are further classified as hemorrhagic (bleeding) or ischemic (non-bleeding). According to Center for Disease Control (CDC) statistics, 140,000 people die each year from strokes in the US and 795,000 people suffer a stroke.
Other common conditions are aneurysms and arteriovenous malformations (AVMs). Aneurysms occur when the arterial wall weakens and starts to bulge, and if it ruptures can cause a Hemorrhagic stroke. AVMs are abnormal vascular connections between the arteries and veins in the brain, these reduce blood flow and thus oxygen carrying capacity. Since people who suffer from strokes and other forms of vascular issues tend to be of Medicare age – which is public information, we can get a good look at the overall cases that are being performed per year.
The surgical procedure with the highest reimbursement was MS-DRG 020 Intracranial vascular procedures w/PDX hemorrhage w/MCC and the lowest surgical procedure was MS-DRG 027 craniotomy & endovascular intracranial procedures w/o CC/MCC. The highest reimbursement for non-surgical medical management in 2020 was for MS-DRG 061 medical management of ischemic stroke or transient ischemia w/TPA w/MCC and the lowest reimbursement was for MS-DRG 066 medical management of hemorrhagic or cerebral infarction w/o CC/MCC. Download the spotlight on neurovascular devices for all the DRGs and their reimbursements. See table: Hospital Medicare Reimbursement for neurovascular cases, FY 2020.
As to the top manufacturers, Stryker, Medtronic, Penumbra, Integra/Codman, and Terumo/Microvention comprised nearly 90% of the neurovascular market in the Curvo Labs database. The largest product category by sales was neurovascular embolization coils, plugs, and other items used in embolization. The next category by sales was thrombectomy catheters, which remove a thrombus in the vasculature.
It is worth noting that some thrombectomy can be done anywhere in the vasculature of the body and some devices used in neurovascular procedures can have other indications such as for peripheral vascular procedures.
Some of the largest neurovascular devices by brands were the Target coils by Stryker, the Solitaire System by Medtronic, the Pipeline flow diverter stent by Medtronic, and the Yasargil aneurysm clip by Aesculap.
