A

inferior epigastric a & v

31
Q

most common type of hernia

A

indirect inguinal

*more common in younger males but still the most common of all the types

32
Q

who is more likely to have an femoral hernia?

A

women

33
Q

direct inguinal hernia

A

medial to inferior epigastric vessels
pass through superficial inguinal ring, pass through Hesselbech’s triangle

34
Q

indirect inguinal hernia

A

lateral to inferior epigastric vessels,
pass through deep inguinal ring and into inguinal canal then through superficial ring

35
Q

Hesselbach’s triangle

A

medial - rectus abdominis m
inf - inguinal ligament
lat - inferior epigastric vessels

36
Q

sports hernia

A

not actual hernia
tear/strain of rectus abdominus m from pubic crest

37
Q

diastasis recti

A

separation of linea alba from increased abdominal pressure
ex: pregnancy

38
Q

cryptorchidism

A

one or both testes undescended
most common site is the inguinal canal

39
Q

varicocele

A

dilated vv in pampiniform plexus from increased venous pressure
“bag of worms”

40
Q

why is varicocele more common on the left side?

A

the acute angle of the L testicular v draining into the L renal v before joining the IVC

41
Q

testicular torsion

A

typically happens unilaterally and is where tissues around around the testes are not attached well to the testes twists around the spermatic cord and blood flow to the testes is cut off

42
Q

what typically protrudes through an incisional hernia?

A

omentum (peritoneum)
fat or an organ

43
Q

what does the inferior epigastric a give rise to?

A

cremasteric a in spermatic cord
