CANS Risk Management & Mitigation 4

Question 1

A patient reports sudden skin blanching in the nasolabial fold area during filler injection. The IMMEDIATE next step is:

Accepted Answer

Apply nitroglycerin paste and massage vigorously, then inject hyaluronidase

Answer

Skin blanching indicates arterial compression or occlusion; nitroglycerin paste causes vasodilation while hyaluronidase dissolves filler to restore perfusion.

Question 2

Which statement about hyaluronidase use in vascular emergencies is CORRECT?

Accepted Answer

It can be injected in high doses across the entire involved vascular territory, not just the injection site

Answer

In vascular occlusion, hyaluronidase should be injected liberally throughout the affected arterial territory, not limited to the injection site, to maximize filler dissolution.

Question 3

Which component of a pre-treatment consultation MOST directly reduces medicolegal risk?

Accepted Answer

Conducting a thorough medical history including medications, allergies, and prior treatments

Answer

A complete medical history identifies contraindications, interaction risks, and prior complications, forming the legal and clinical basis for safe treatment.

Question 4

When managing a patient with post-procedural hyperpigmentation after laser treatment, which risk factor should have been identified in the pre-treatment assessment?

Accepted Answer

Fitzpatrick skin types IV–VI or recent sun exposure

Answer

Darker Fitzpatrick skin types and recent UV exposure are the primary predictors of post-inflammatory hyperpigmentation after laser procedures.

Question 5

A patient wants to combine neurotoxin and filler in the same session. The most important risk mitigation step is:

Accepted Answer

Complete filler placement first to avoid toxin migration distorting filler landmarks

Answer

Filler should be placed before neurotoxin in combination sessions to preserve anatomical muscle landmarks; neurotoxin can then be applied without distorting injection guidance.
