1

What is the femoral triangle boundaries?

card image

Superiorly - Inguinal ligament

Laterally - Sartorius

Medically- Adductor longus

2

What is the femoral sheath?

Fascial tube 3-4cm below inguinal ligament that cantains the femoral vein, artery, and deep inguinal lymph nodes but NOT femoral Nerve

3

What is the proper organization of the vein artery nerve in the femoral triangle?

card image

NAVeL Lateral to Medial

Nerve,Artery,Vein,empty, Lymph

4

The layers of abdominal muscles superficial to deep?

External Oblique

Internal Oblique

Transversus Abdominis

Tranversalis facsia

5

The spermatic cord is composed of what layers of aponeurosis?

card image

ICE tie

Internal spermatic fascia = tranversalice

Cremasteric muscle = internal oblique

External spermatic fascia = external oblique (anatomic hole passes the spermatic cord thru this structure)

6

What is a hernia?

A protrusion of peritoneum through an opening, usually at a site of weakness

7

What is at risk when you have a hernia?

incarceration = can't go back

Strangulation = ischemia

8

What are the four major types of hernias?

Diaphragmatic

Indirect inguinal

Direct inguinal

Femoral

9

What is a diaphragmatic hernia (Hiatal hernia)?

Abdominal structures enter the thorax thru weakness or congenital defect?

10

Which size is a diaphragmatic hernia most common?

left because liver protects the right.

11

What are the two subtypes of diaphragmatic hernias?

Sliding and para-esophageal

12

What is a sliding hernia?

Gastroesophageal junction is displaced upward

gives Hourglass stomach

13

What is a paraesophagel hernia?

Fundus protrudes into the thorax.

14

What are the locations of ingual (direct/indircet) and femoral?

card image

Direct inguinal is medial to inf epigastic vessels

Indirect inguinal is Lateral to inf. epigastic vessels

Femoral in inferior to inguinal ligament and medial to femoral vessels

15

Indirect inguinal hernia enter where?

DEEP inguinal ring into scrotum (covered by same three layers as spermatic fascia)

Lateral to inf. epigastric vessels

16

What may causes indirect inguinal hernias in infants?

failure of processus vaginalis to close

Males>>>females

17

Where does a direct inguinal hernia go?

Directly thru inguinal(hesselbach) triangle.

Medial to inf. epigastric vessels

ONLY EXTERNAL part of spermatic cord

18

Femoral Hernias more common in men or women?

COmplications?

Women

Strangulation higher risk

19

What is the inguinal (Hesselbach) triangle?

card image

Inferior Epigastric vessels

Lateral Rectus Abdominis

Inguinal Ligament
