Anastomosis of I

Anastomosis of I in anatomy:

  1. Anastomosis – PNA (The anatomic nomenclature Parisian); Greek anastomosis – an anastomosis, from anastomoo – to supply with the mouth, an opening – natural connection of two hollow bodies (for example, channels, vessels);
  2. Anastomotic vessel (устар.) connecting two lymphatic or a blood vessel.

Allocate the following types of an anastomosis:

  • Arterial (arterialis) – an anastomosis in the form of an arterial branch or network which connects two arterial vessels;
  • Arterial extra organ (arterialis extraorganica) – an arterial anastomosis between the sites of arteries located out of the body supplied by them;
  • Arterial intraorganic (arterialis intraorganica) – an arterial anastomosis between sites of an artery in the body supplied by it;
  • Arterial intrasystem (arterialis intrasystemica) – an arterial anastomosis between branches of one main artery;
  • Arterial intersystem (arterialis intersystemica) – an arterial anastomosis between branches of various main arteries;
  • Arteriovenous glomerular [arteriovenosa glomeriformis – LNH (The Leningrad histologic nomenclature); synonym: a glome] – an arteriolovenulyarny anastomosis in the form of a ball of gyrose vessels which is surrounded with a joint capsule and is supplied with numerous nerve terminations;
  • Arteriolovenulyarny [arteriolovenularis – PNA (The anatomic nomenclature Parisian); arteriovenosa – BNA (The anatomic nomenclature Basel), JNA (The anatomic nomenclature Yenskaya); synonym: an arteriovenous anastomosis] – connection between an arteriole and a venule;
  • Venous (venosa) – between two venous vessels;
  • Kavo-kavalny (cavo-cavalis) – a venous anastomosis between inflows of the lower and upper venas cava;
  • Carotid and basilar (carotidobasilaris) – the arterial anastomosis between an internal carotid and basilar artery of a germ which is reduced by the time of the birth; at later age is anomaly of development;
  • Porto-caval (portocavalis) – a venous anastomosis between inflows hollow and portal veins; it is located in walls of an upper part of a rectum, a belly part of a gullet, etc.;
  • Channels [ductuum – LNE (The Leningrad embryological nomenclature)] – connection of a dorsal and ventral pancreat duct of a germ.

In Great Britain there is a law according to which the surgeon can refuse to do to the patient operation if he smokes or has excess weight. The person has to refuse addictions, and then, perhaps, he will not need an operative measure.
