Abstract
This case report describes a patient with a history of liver cirrhosis who underwent neck reconstruction surgery and subsequently experienced substantial chyle leakage, reaching volumes of up to 6,620 mL per day. Conservative interventions such as fasting, a low-fat diet, total parenteral nutrition, drainage management, somatostatin analogs, and factor XIII supplementation proved ineffective, and the patient exhibited a refractory treatment course. The pronounced chyle leakage in this instance was hypothesized to be linked to increased lymph production resulting from portal hypertension associated with liver cirrhosis. Given the resistance to conservative treatment, thoracic duct embolization was performed by the interventional radiology department, effectively controlling the chyle leakage. The patient experienced a favorable clinical trajectory, devoid of complications. These findings indicate that thoracic duct embolization is a safe and efficacious minimally invasive treatment for refractory and massive chyle leakage following neck dissection and may represent a promising alternative before surgical intervention.
