Most common complication of mastectomy is:
**Core Concept**
Lymphedema is a chronic swelling of the limb, typically the arm, caused by the disruption of lymphatic vessels and nodes, often resulting from surgical removal or damage to these structures.
**Why the Correct Answer is Right**
The most common complication of mastectomy is indeed lymphedema, particularly in the arm. This occurs due to the removal or damage of lymph nodes and vessels during the surgical procedure. The lymphatic system plays a crucial role in the drainage of interstitial fluid, proteins, and other substances from the arm. When this system is compromised, fluid accumulation leads to swelling, which can become chronic and irreversible if not managed properly. The risk of lymphedema is higher in patients undergoing axillary dissection or radiation therapy.
**Why Each Wrong Option is Incorrect**
**Option A:** Seroma is a potential complication of mastectomy, but it is not the most common one. Seroma refers to the accumulation of fluid in the surgical wound, which can be managed with drainage or aspiration.
**Option B:** Infection is a possible complication of mastectomy, but it is not the most common one. Infection can be prevented with proper wound care and antibiotic prophylaxis.
**Option C:** Hematoma is a potential complication of mastectomy, but it is not the most common one. Hematoma refers to the accumulation of blood in the surgical wound, which can be managed with drainage or compression.
**Clinical Pearl / High-Yield Fact**
Lymphedema is a preventable complication of mastectomy if proper lymphatic sparing techniques are employed during surgery, and patients receive postoperative care and education on lymphedema prevention and management.
**Correct Answer:** D. Lymphedema.
