Postcoarctectomy mesenteric arteritis presenting as neonatal appendicitis.

Area of Science:

• Pediatric Surgery
• Vascular Surgery
• Neonatal Medicine

Background:

• Coarctation of the aorta is a congenital heart defect requiring surgical repair.
• Post-operative complications can arise, necessitating vigilant monitoring in neonates.
• Mesenteric arteritis is a rare but serious inflammatory condition affecting mesenteric blood vessels.

Observation:

• A case of mesenteric arteritis occurred in a 5-day-old infant following coarctectomy.
• The condition presented diagnostic challenges, leading to a delayed diagnosis.
• The infant experienced a fatal outcome due to the complications of mesenteric arteritis.

Findings:

• Mesenteric arteritis post-coarctectomy is a critical diagnostic consideration in neonates.
• Key alert symptoms include fever, intestinal bleeding, ileus, nausea, vomiting, leukocytosis, hypertension, and abdominal pain.
• Prompt initiation of treatment is vital to avert severe consequences.

Implications:

• Increased awareness of mesenteric arteritis is needed in neonates with similar surgical histories.
• Developing diagnostic protocols for post-operative mesenteric arteritis can improve patient outcomes.
• Early intervention strategies are essential for managing this rare but life-threatening complication in infants.
