20장, 문제 15

Mrs. Jackson, a 59-year-old woman, has undergone a left radical mastectomy (removal of the left breast and left axillary lymph nodes and vessels). Her left arm is severely swollen and painful, and she is unable to raise it to more than shoulder height.
Explain her signs and symptoms.
Can she expect to have relief from these symptoms in time? How so?

Step 1: Understand the surgical procedure and its consequences. A left radical mastectomy involves removal of the left breast along with the left axillary lymph nodes and vessels. These lymph nodes and vessels are crucial for draining lymph fluid from the left arm and surrounding tissues.
Step 2: Explain the cause of swelling (lymphedema). Since the lymph nodes and vessels on the left side have been removed, lymph fluid cannot drain properly from the left arm, leading to accumulation of fluid in the tissues. This causes swelling (lymphedema), which also results in pain and limited mobility.
Step 3: Connect the swelling to the limited arm movement. The severe swelling increases tissue pressure and discomfort, making it difficult and painful for Mrs. Jackson to raise her left arm above shoulder height.
Step 4: Discuss the potential for symptom relief over time. Some relief may occur as the body develops collateral lymphatic pathways to bypass the removed nodes, improving lymph drainage gradually. Additionally, physical therapy and compression garments can help reduce swelling and improve arm function.
Step 5: Emphasize the importance of ongoing management. While some improvement is possible, lymphedema can be chronic and may require lifelong care to manage symptoms and prevent complications such as infections.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Lymphedema

Lymphedema is swelling caused by the accumulation of lymph fluid, often occurring after lymph node removal or damage. In Mrs. Jackson's case, removal of axillary lymph nodes disrupts normal lymph drainage from the left arm, leading to fluid buildup, swelling, and pain.

Radical Mastectomy and Its Complications

A radical mastectomy involves removing the breast tissue along with axillary lymph nodes and vessels, which can damage lymphatic pathways. This surgery increases the risk of complications like lymphedema and restricted arm movement due to tissue scarring and nerve injury.

Management and Prognosis of Post-Mastectomy Lymphedema

While lymphedema can be chronic, symptoms may improve with treatments such as physical therapy, compression garments, and lymphatic drainage massage. Early intervention helps reduce swelling and pain, improving arm mobility and quality of life over time.

Once almost a rite of childhood, tonsillectomy (surgical removal of the tonsils) is now rarely performed. Similarly, while ruptured spleens were once routinely removed, they are now conserved whenever possible. Why should these lymphoid organs be preserved when possible?

A friend tells you that she has tender, swollen 'glands' along the left side of the front of her neck. You notice that she has a bandage on her left cheek that is not fully hiding a large infected cut there. Exactly what are her swollen 'glands,' and how did they become swollen?
