Chimney
Chimney (medicine)
Chimney (pronunciation: /ˈtʃɪmni/) is a term used in the medical field, particularly in the context of vascular surgery and interventional radiology. It refers to a technique used in endovascular procedures to preserve flow to branch vessels while excluding an aneurysm or other pathological condition.
Etymology
The term "chimney" in this context is derived from the visual similarity between the technique used in the procedure and a real-life chimney. The graft used in the procedure is likened to a chimney flue, allowing flow to continue unimpeded.
