What does anastomosed mean?
"Anastomosed" describes tubular structures — most often blood vessels, but also plant veins, fungal filaments, and river channels — that have been joined so that they interconnect and allow flow between them. It serves both as the past tense of the surgical verb "anastomose" (as in "the surgeon anastomosed the artery to the graft") and as an adjective for naturally or artificially interconnected networks (as in "richly anastomosed capillaries"). The term derives from Greek roots meaning roughly "to furnish with a mouth," reflecting the idea of opening one channel into another. Because it is technical vocabulary, it appears chiefly in medical literature, operative reports, and scientific descriptions rather than everyday conversation, where simpler words like "connected" would be preferred. For readers of anatomy, surgery, or vascular medicine, however, it is indispensable vocabulary.
Connected surgically or naturally so as to open communication between tubular structures.
"The surgeon anastomosed the vein graft to the coronary artery."
Almost always encountered in passive constructions in clinical writing: 'the vessels were anastomosed'.
Describing vessels or channels that are interconnected so that flow can pass between them.
"The tumor was fed by a network of anastomosed vessels."
The word comes from Greek roots meaning 'to provide a mouth' — because when surgeons join two vessels, they are literally giving the circulation a new opening between them.

Etymology of anastomosed
"Anastomosed" stems from the Greek "anastomōsis," formed from "ana-" ("up, back") and "stoma" ("mouth"), literally suggesting the provision of an opening or outlet. The noun "anastomosis" entered English via Latinized medical usage around the early 17th century, and the verb "anastomose" followed as surgeons and anatomists needed a way to describe creating such connections. Other English words sharing the "stoma" root include "stoma" itself (used in botany and surgery) and "stomatitis" (inflammation of the mouth).
