ABSTRACT
ABSTRACT

Objective:

to report the prevalence of arterial corona mortis and to describe its surgical and clinical applicabilities.

Methods:

We dissected 60 hemipelvises (50 men and 10 women) fixed in a 10% formalin solution for the purpose of gathering information on corona mortis. We measured the caliber and length of the obturator artery and its anastomotic branch with the aid of a digital caliper and submitted the data to statistical analyzes and comparisons with the GraphPad Prism 6 software.

Results:

arterial corona mortis was present in 45% of the studied sample. The most common origin of the obturator artery was the internal iliac artery; however, there was one exceptional case in which it originated from the femoral artery. The caliber of the anastomotic branch was on average 2.7mm, whereas the caliber of the obturator artery was 2.6mm.

Conclusion:

the vascular connections between the obturator, internal iliac, external iliac and inferior epigastric arterial systems are relatively common over the upper pubic branch. The diameter and a trajectory of the anastomotic artery may vary. Thus, iatrogenic lesions and pelvic and acetabular fractures can result in severe bleeding that puts the patient's life at risk.
RESUMO
RESUMO

Objetivo:

relatar a prevalência da corona mortis arterial e descrever suas aplicabilidades cirúrgicas e clínicas.

Métodos:

sessenta hemipelvises (50 homens e 10 mulheres) fixadas em uma solução de formalina a 10% foram dissecadas com o propósito de obter informações sobre a corona mortis. Medidas do calibre e comprimento da artéria obturatória e seu ramo anastomótico foram mensuradas com o auxílio de um paquímetro digital e submetidas a análises e comparações estatísticas no programa GraphPad Prism 6.

Resultados:

a corona mortis arterial esteve presente em 45% da amostra estudada. A origem mais comum da artéria obturatória foi da artéria ilíaca interna, porém, houve um caso excepcional no qual a artéria obturatória se originou da artéria femoral. O calibre do ramo anastomótico foi em média 2.7mm, enquanto que o calibre da artéria obturatória foi 2.6mm.

Conclusão:

as conexões vasculares entre os sistemas obturatório, ilíacos interno e externo e epigástrico inferior são relativamente comuns sobre o ramo superior da pube. O diâmetro e a trajetória dessa artéria anastomótica podem variar. Assim, lesões iatrogênicas, fraturas pélvicas e acetabulares podem resultar em hemorragias graves que colocam a vida do paciente em risco.
