Flashcards in Inguinal Region Deck (19):
0

Cold lower border of external oblique muscle

From ASIS to pubic tubercle

Inguinal ligament

1

Oval opening in transversalis fascia

Lateral to inferior epigastric artery

Deep inguinal ring

2

Triangular opening in external oblique muscle

Lateral to pubic tubercle

Superficial inguinal ring

3

Begins from deep to superficial inguinal ring

Transmit the following structures:
- spermatic cord (males)
- round ligament of the uterus (female)

Inguinal canal

4

Protrudes directly through anterior abdominal wall within Hesselbach triangle

Medial to inferior epigastric vessels

Older males, rare in women

Protrudes on straining, disappears at rest

Felt with pulp of the finger

Direct inguinal hernia

5

Protrudes through the deep inguinal ring --> enters inguinal canal --> superficial inguinal ring (exit) --> scrotum

Lateral to inferior epigastric vessels

Above & medial to the pubic tubercle

Young males

Tender, painful mass that continues into the scrotum

Felt with tip of the finger

Indirect inguinal hernia

6

Protrudes through femoral canal below the inguinal ligament

Below & lateral to the pubic tubercle

Medial to femoral vein

More common in females, appears on right side

Prone to early strangulation

Femoral inguinal hernia

7

Surgical repairs of hernias

Bassini repair

McVay repair (Cooper ligament repair)

8

Transversalis fascia & conjoint tendon are sutured to inguinal ligament (Poupart's ligament)

Bassini repair

9

Transversalis fascia & conjoint tendon are sutured to Cooper's ligament (pectineal ligament)

McVay repair (Cooper ligament repair)

10

Surgical repair may damage the ff nerves:

Iliohypogastric nerve
- anesthesia of ipsilateral abdominal wall & inguinal region

Ilioinguinal nerve
- anesthesia of ipsilateral penis, scrotum & medial thigh

11

Layers of abdominal wall

Skin

Superficial fascia
(Camper & Scarpa)

Superficial perineal space (extravasated urine)

External oblique muscle

Internal oblique muscle

Transverse abdominis muscle

Transversalis fascia

Extraperitoneal fat

Parietal peritoneum

12

Coverings of testes & spermatic cord

Skin

COLLE'S fascia & Dartos muscle

Superficial perineal space (extravasated urine)

External spermatic fascia

Cremasteric fascia & muscle

Does not continue into scrotal area

Internal spermatic fascia

Extraperitoneal fat

Tunica vaginalis

13

Testis fails to descend into scrotum, testis may be found in inguinal canal or abdominal cavity

Cryptorchidism

14

Small patency of processus vaginalis allows peritoneal fluid to flow into --> fluid filled cyst

Hydrocele

15

Metastasize to superficial inguinal nodes

Scrotal cancer

16

Metastasize to deep lumbar nodes near renal hilus

Testicular cancer

17

Extravasated urine from saddle injury --> leak into superficial perineal space between COLLE'S fascia & Dartos muscle & external spermatic fascia

Trauma

18

Vasectomy citrus through the ff:

Skin --> COLLE'S fascia & Dartos muscle --> external spermatic fascia --> cremasteric fascia & muscle --> internal spermatic fascia --> extraperitoneal fat

- Tunica Vaginalis is not cut
