Lymphatic imaging and intervention in a pediatric population: Anesthetic considerations

Area of Science:

• Pediatric Anesthesiology
• Interventional Radiology
• Lymphatic Imaging and Intervention

Background:

• Severe pediatric lymphatic disorders often require advanced diagnostic and therapeutic interventions.
• These procedures necessitate general anesthesia due to immobility requirements for accurate catheter/needle placement and patient comfort.
• Managing medically complex pediatric patients under anesthesia presents significant logistical and medical challenges.

Purpose of the Study:

• To review the anesthetic management and outcomes of pediatric patients undergoing lymphatic imaging and intervention.
• To evaluate the safety and feasibility of these procedures in a specialized pediatric center.
• To identify complications and care escalation patterns in this high-risk population.

Main Methods:

• Retrospective review of a one-year cohort of pediatric patients undergoing lymphatic procedures.
• Data collected included patient demographics, comorbidities, anesthetic details, concurrent procedures, and intensive care unit (ICU) outcomes.
• All patients received general anesthesia with paralysis and controlled ventilation.

Main Results:

• 106 anesthetics were administered to 68 pediatric patients (4 days to 17 years).
• 98% of patients were American Society of Anesthesiologists (ASA) class 3 or 4, with 79.4% having significant comorbidities.
• 76% of procedures involved concurrent interventions; 25% of patients experienced complications within 24 hours of ICU admission.

Conclusions:

• Improved lymphatic access and Dynamic Contrast-enhanced Magnetic Resonance Lymphangiography enable treatment for severe lymphatic disorders.
• Anesthetic management for these high-risk pediatric patients is complex, often involving multiple procedures.
• Intensive care observation is crucial for managing potential complications in the immediate postoperative period.
