Corona mortis

The corona mortis or also the arcus mortis ( Latin "wreath of death" from corona , "crown" or "wreath" or arcus , "[vessel] arch" and mors, mortis , "death") is particularly well developed Anastomosis (vascular connection) between the inferior epigastric artery and the obturator artery .

In addition to the arteria cremasterica in men and the arteria ligamenti teretis uteri in women, the inferior epigastric artery gives off a ramus pubicus (vascular branch), which in turn sends out a ramus obturatorius . This ramus obturatorius anastomoses with the ramus pubicus , which is given off by the arteria obturatoria . This anastomosis runs over the femoral septum (→ Lacuna musculorum et vasorum ), which can serve as a hernial port for a femoral hernia . For operations of such a breach may be difficult satiable bleeding occur in violation of the vessels, which v. a. previously resulted in a correspondingly high mortality and thus justified the name of corona mortis . Today, any bleeding that occurs can be treated better, for example by embolization (see Hemostasis for further medical practices on hemostasis). The risk can also be better assessed preoperatively through sonography or angiography . Nevertheless, a residual risk cannot be ruled out.

In addition to the often described anastomosis between arteries as the cause of corona mortis , venous structures can also lead to similar complications.
