| Roux-en-Y anastomosis | Anastomosis of the distal end of the divided jejunum to the stomach, bile duct, or another structure, with implantation of the proximal end into the side of the jejunum at a suitable distance below the first anastomosis, the bowel then forming a Y-shaped pattern. (05 Mar 2000) |
| microvascular anastomosis | Anastomosis of very small blood vessels performed under a surgical microscope. (05 Mar 2000) |
| circular anastomosis | Anastomosis performed after cutting each structure to be joined in a plane vertical to the ultimate flow through the structures. (05 Mar 2000) |
| Clado's anastomosis | Anastomosis in the right suspensory ligament of the ovary between the appendicular and ovarian arteries. (05 Mar 2000) |
| conjoined anastomosis | The joining together of two small blood vessels by side-to-side elliptical anastomosis to create a single larger stoma for subsequent end-to-end anastomosis. (05 Mar 2000) |
| postcostal anastomosis | <anatomy> Longitudinal anastomosis of intersegmental arteries giving rise to the vertebral artery. (05 Mar 2000) |
| cruciate anastomosis | Crucial anastomosis, a four-way anastomosis between branches of the first perforating branch of the deep femoral, inferior gluteal and medial and lateral circumflex femoral arteries, located posterior to the upper part of the femur. Formerly described as commonly occurring; investigations show it rarely occurs in the four-way "cross" pattern. (05 Mar 2000) |
| Potts' anastomosis | Direct side-to-side anastomosis between aorta and pulmonary artery as a palliative procedure in congenital malformation of the heart. Synonym: Potts' anastomosis. (05 Mar 2000) |
| precapillary anastomosis | An anastomosis between arterioles just before they become capillaries. (05 Mar 2000) |
| precostal anastomosis | Longitudinal anastomosis of intersegmental arteries in the embryo that gives rise to the thyrocervical and costocervical trunk. (05 Mar 2000) |
| Hofmeister-Polya anastomosis | More specifically see Hofmeister's operation, Polya's operation. (05 Mar 2000) |
| Hyrtl's anastomosis | A communicating loop between the right and left hypoglossal nerves, lying between the geniohyoid and genioglossus muscles or in the substance of the geniohyoid; it is found in about one in ten persons. Synonym: Hyrtl's anastomosis. (05 Mar 2000) |
| Damus-Stancel-Kaye anastomosis | A procedure for subaortic stenosis, entails the creation of an end-to-side pulmonary trunk/aortic anastomosis, performed along with a Fontan procedure, particularly for patients with a double inlet left ventricle. Synonym: Damus-Stancel-Kaye anastomosis. (05 Mar 2000) |
| intermesenteric arterial anastomosis | The series of arterial arches formed in the mesentery by anastomoses between adjacent jejunal and ileal arteries and from which vasa recta arise. The arterial arcades of the ileum are shorter and more complex than those of the jejunum. See: arterial arches of ileum, arterial arches of jejunum. Synonym: intermesenteric arterial anastomosis, Riolan's arc, Riolan's arcades. (05 Mar 2000) |
