CSFA Intraoperative Procedures and Techniques 4

Question 1

During a mastectomy with sentinel lymph node biopsy, the blue-stained lymph node is identified but appears to be in close proximity to the axillary vein. What is the first assistant's primary responsibility at this moment?

Accepted Answer

Provide meticulous retraction and clear visualization to protect the vein during dissection

Answer

The first assistant's primary role is to provide optimal retraction and exposure so the surgeon can safely dissect the sentinel node away from the axillary vein.

Question 2

What does the term 'cystotomy' refer to in the context of intraoperative technique?

Accepted Answer

Incision into the urinary bladder or cystic structure

Answer

Cystotomy is the surgical incision into the bladder or any cystic structure, commonly performed for stone removal or intravesical procedures.

Question 3

During a laparoscopic appendectomy, the surgical first assistant is using an endoscopic stapler to divide the mesoappendix. The stapler fires but the tissue appears inadequately transected. What is the correct next step?

Accepted Answer

Notify the surgeon and evaluate the staple line before proceeding

Answer

A misfire or incomplete staple line requires stopping to assess the situation with the surgeon before any further action to prevent hemorrhage or incomplete division.

Question 4

When assisting during an open inguinal hernia repair using the Lichtenstein tension-free mesh technique, the mesh is anchored along the inguinal ligament using which suture material?

Accepted Answer

Monofilament permanent or slowly absorbable suture

Answer

Permanent or slowly absorbable monofilament suture secures the mesh to the inguinal ligament to ensure durable fixation without long-term foreign body braided suture issues.

Question 5

A patient undergoing a total knee arthroplasty has a tourniquet applied to the upper thigh. The surgical first assistant is asked to set the tourniquet pressure. What is the standard recommended tourniquet pressure for a lower extremity procedure?

Accepted Answer

100–150 mmHg above systolic blood pressure

Answer

Tourniquet pressure for the lower extremity is typically set 100–150 mmHg above systolic pressure to ensure arterial occlusion while minimizing tissue damage.
