Multiple Choice Questions MCQ

Question 24# Print Question

Which statement is false?

A. The parascapular flap is vascularized by the transverse branch of the circumflex scapular vessels

B. The anterolateral thigh flap is normally vascularised by the descending branch of the lateral circumflex femoral vessels

C. The skin island of the osteocutaneous fibula free flap is generally circulated by septocutaneous branches from the peroneal vessels running off posterior of the fibula

D. The venous outflow of the radial forearm flap can be based on either the concomitant veins of the radial artery or on the cephalic vein or on both

E. The scapular angle is circulated through the angular branch which comes from the thoracodorsal vessels

Question 21# The names of Salmon, Manchot, Taylor, Morain, and Tempest are all associated with our knowledge of which of the following?
A. Microsurgery
B. Breast reconstruction
C. Blood supply to skin
D. Nerve supply to skin
E. Free flap reconstruction
Blood supply to skin. Carl Manchot wrote about the blood supply of the skin in 1889 and Michel-Marie Salmon used radio opaque preservatives to investigate the arteries of the skin in 1936. Manchot’s work was reviewed by Morain in 1985 and Salmon’s was translated and edited by Taylor and Tempest in 1988.

Question 22# To prevent microvascular anastomosis occlusion in a standard microsurgical case you should:
A. Keep the operating theatre temperature high
B. Make sure both vessels are of the same caliber
C. Make sure there is no intimal damage in either vessel
D. Inject a bolus of heparin before putting the clamp on the vessel
E. Never release the vein before starting the arterial anastomosis
Make sure there is no intimal damage in either vessel. The only real issue is to have good flow with undamaged intima and no debris inside the vessel or at the anastomotic site in a standard case with no other associated blood clotting or trauma issues.

Question 23# Which of the following statements is false?
A. Polyglactic acid (Vicryl®) is a synthetic polyfilament suture which loses its tensile strength after 4-5 weeks and is said to be absorbed at 3 months
B. Polydioxanone (PDS®) is a synthetic monofilament suture which loses its tensile strength after 3 weeks and is absorbed at 2 months
C. Polypropylene (Prolene®), a polymer of propylene, is a monofilament, non-absorbable suture which can be used to repair fascia, tendon, muscle and vessels
D. ‘Catgut’ sutures are derived from sheep intestine, lose their tensile strength after 7-10 days, and are absorbed at 2 months
E. All of the above
PDS sutures maintain tensile strength for up to 8 weeks, and take up to 6 months to absorb.

Question 25# When a free flap is failing due to venous or arterial thrombosis:
A. Do not re-explore because the salvage rate is low
B. It is reasonable to re-explore the next day
C. The use of streptokinase is the procedure of choice
D. Administer IV heparin and wait
E. It is necessary to attempt removal of the entire propagated clot

Question 24# Which statement is false?
A. The parascapular flap is vascularized by the transverse branch of the circumflex scapular vessels
B. The anterolateral thigh flap is normally vascularised by the descending branch of the lateral circumflex femoral vessels
C. The skin island of the osteocutaneous fibula free flap is generally circulated by septocutaneous branches from the peroneal vessels running off posterior of the fibula
D. The venous outflow of the radial forearm flap can be based on either the concomitant veins of the radial artery or on the cephalic vein or on both
E. The scapular angle is circulated through the angular branch which comes from the thoracodorsal vessels
The parascapular flap is vascularised by the transverse branch of the circumflex scapular vessels. A is false; the parascapular flap is supplied by the descending branch; the scapula flap is supplied by the transverse branch.
