a 44 y/o woman is brought to the emergency deparment 40 minutes after being stabbed in the left groin. bp: 120/84, pulse: 100, resp: 16. examination of the wound shows a small hematoma and no external bleeding. popliteal and pedal pulses are palpable in the left lower extremity below the injury. lacerations of the femoral artery and vein are found and reapaired. three days postoperatively she has progresively severe pain in the lef lower extremity, and swelling of the leg from the knee down. which of the following is the most likely cause of her new symptoms?

a) arterial embolism
b) compartment syndrome
c) lymphatic disruption of the injury
d) thrombosis of the femoral vein
e) wound hemorrhage

ok may b its compartment synd

D

what's the Mx in this situation of femoral vein thrombosis?

b) compartment syndrome

compartment syndrome after vascular injury, may be due to reperfusion. This reperfusion syndrome is likely related to the ischemic depletion of high-energy phosphate forms and ischemic muscle injury.

there is no pain of the passive movements, just swelling is not enough for the diagonosis of compatment syndrome. i would go for D. because of surgery, the function of vein is disturbed and the blood flow is deceased and ... So I guess the answer is D

  #12

Why not C? the lymphatics are for sure damaged and why is the leg only swollen below the knee? not very typical for DVT also there are no DVT signs described.

I took C


  #13

sever pain. after vascular injury.... mm I am thinking compartment syndrome wink

  #14

Compartment syndrome does NOT present 3 days post op. Lymphatic obstruction would not present with pain only progressive edema. Arterial would present differently with decreased pulses or cyanosis. I go for thrombosis, progressive pain and swelling is typical. If they told u all the classical signs of DVT this q would be too easy.


  #15

Agree with D

  #16

hm i had lymphatic obstruction and that is painful. i also saw some patients with painful lymphedema. i still dont know what the fact that the sweeling is only below the knee should tell us?

  #17

I picked C too.
The structures are injured but only vessles were repaired.

d
check the difference.
Lymphedema

Essentials of Diagnosis

Painless edema of upper or lower extremities.
Involves the dorsal surfaces of the hands and fingers or the feet and toes.
Developmental or acquired, unilateral or bilateral.
Edema is pitting initially and becomes brawny and nonpitting with time.
Ulceration, varicosities, and stasis pigmentation do not occur. There may be episodes of lymphangitis and cellulitis.


  #19

B or D?
Not sure, but tilts towards venous thrombosis
