Plural form; surgical procedures involving making an incision into an artery to access it for treatment or examination.
From 'arterio-' (artery) + Greek '-tomy' (cutting). This medical procedure term follows standard surgical naming conventions, with the plural indicating multiple such procedures.
Arteriotomies are often the first step in modern vascular surgery—surgeons must cut into an artery to thread in catheters, remove clots, or repair aneurysms, making this one of the most fundamental techniques in saving lives from vascular emergencies.
