Deck 44: Vascular Surgery

Question 1

Which type of aneurysm is caused by a break in the integrity of the vessel wall,which requires an open repair?

A) Pseudoaneurysm
B) True aneurysm
C) Dissecting aneurysm
D) Saccular aneurysm

Answer 1

A
A pseudoaneurysm is usually caused by a break in the integrity in the vessel wall and this causes all the layers of the vessel to separate and bulge.A pseudoaneurysm differs from true aneurysm because it is caused by an outside source rather than vascular pathology.

Question 2

MATCHING
Match each procedure with its definition.
a.Embolectomy
b.Atherectomy
c.Balloon dilation
d.Intraluminal stent
e.Laser angioplasty
f.Thrombolytic therapy
g.Thrombectomy

Answer 2

E

Question 3

Which shunt is used to relieve portal hypertension to decompress esophageal varices?

A) Mesocaval shunt
B) Hepatorenal shunt
C) Suprahepatic shunt
D) Portacaval shunt

Answer 3

D
The portacaval shunt relieves hypertension by bypassing the obstruction and diverting the return flow of blood to the liver from the portal vein,thus decompressing esophageal varices.

D) Pulmonary fibrosis

Question 11

Which is a reason a shunt is used routinely during a carotid endarterectomy?

A) To prevent blood loss
B) To avoid making an arteriotomy in the carotid artery

Question 15

Which is a potential serious complication of a carotid endarterectomy?

A) Keloid scar formation
B) Brain injury due to embolized plaque
C) Inflammation due to scar formation
D) Anaphylactic reaction to thrombin

Question 16

Which of the following are used to protect the small intestine and colon during an abdominal aneurysmectomy?
