Question 1

Which complication is most feared after hepatic arterial chemoembolization?

Accepted Answer

Post-embolization syndrome

Answer

Post-embolization syndrome (fever, pain, nausea) is the most common complication after TACE, though hepatic abscess and non-target embolization are most feared serious complications.

Question 2

In inferior vena cava filter placement, what is the preferred infrarenal placement position?

Accepted Answer

Below the renal veins to preserve renal vein drainage

Answer

Infrarenal placement preserves renal vein drainage and avoids caval thrombosis that would compromise renal function.

Question 3

Absolute contraindication to thrombolysis in acute limb ischemia includes:

Accepted Answer

Recent stroke within 2 months

Answer

Recent stroke within 2 months is an absolute contraindication to catheter-directed thrombolysis due to the high risk of intracranial hemorrhage.

Question 4

Radiofrequency ablation (RFA) of liver tumors causes cell death primarily through:

Accepted Answer

Thermal coagulation necrosis from resistive heating

Answer

RFA applies alternating current that causes ionic agitation and frictional resistive heating, producing coagulative necrosis at temperatures above 60°C.

Question 5

Which angiographic finding is pathognomonic of active gastrointestinal hemorrhage?

Accepted Answer

Extravasation of contrast into the bowel lumen

Answer

Active contrast extravasation pooling in the bowel lumen during mesenteric angiography directly identifies the bleeding point and guides embolization.
