According to a [systematic review of published data](https://pubmed.ncbi.nlm.nih.gov/32835790/), the overall mortality rate following major amputation is: - 3.5% at one month - 20% at one year - 28% at three years - 44.1% at five years - 51.3% at six to seven years - 58.5% at eight to nine years Add to that the increased risks of depression, decreased mobility and loss of independence, and the case for prioritizing limb salvage is undeniable. Infrainguinal bypass has the power to change a patient’s trajectory, but only if the bypass works. Measuring blood flow intraoperatively helps surgeons confirm that the bypass is working.  ## Why Measure Flow  A successful bypass requires three things: adequate inflow, a patent graft and good outflow. Even the most experienced surgeons can encounter technical complications like poor anastomosis, graft kinks or narrowing. When flow isn’t measured during the procedure, these issues may go undetected until the patient returns with symptoms or the graft fails entirely. That’s where [Transonic Vascular Flowprobes (FMV-Series)](https://www.transonic.com/vascular-flowprobes) and [Transonic Optima Flowmeter](https://www.transonic.com/optima-meters) make the difference, allowing you to: - Confirm graft patency before closure - Quantify blood flow in mL/min, not just velocity - Make data-driven, in-the-moment surgical decisions that reduce the risk of early failure It’s a simple addition to your workflow, but one that can have a major impact on outcomes.
