Splenectomy done in:
**Core Concept**
Splenectomy, or the surgical removal of the spleen, is a procedure that can be performed for various indications, including trauma, splenic rupture, hematological disorders, and certain types of cancers. The spleen plays a crucial role in filtering the blood, storing red blood cells, and acting as a reservoir for immune cells.
**Why the Correct Answer is Right**
The correct answer is typically associated with a condition where the spleen is severely damaged or non-functional, leading to significant morbidity and mortality. In such cases, splenectomy may be the only viable option to prevent further complications. The surgical removal of the spleen can help alleviate symptoms, prevent further bleeding, and improve overall patient outcomes.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because spleen preservation is often attempted in cases of trauma or splenic rupture, especially in children and young adults, to avoid the complications associated with splenectomy.
**Option B:** This option is incorrect because liver transplantation is a separate surgical procedure that involves replacing the entire liver, whereas splenectomy involves the removal of the spleen.
**Option C:** This option is incorrect because pancreas transplantation is a complex surgical procedure that involves replacing the pancreas, whereas splenectomy involves the removal of the spleen.
**Clinical Pearl / High-Yield Fact**
Splenectomy is often associated with an increased risk of infections, particularly those caused by encapsulated bacteria such as Streptococcus pneumoniae and Haemophilus influenzae. Patients who have undergone splenectomy should receive prophylactic vaccination against these pathogens to reduce the risk of severe infections.
**Correct Answer: C. Splenic artery aneurysm.**
