Lymphatic leak complicating central venous catheter insertion

Area of Science:

• Cardiology
• Vascular Surgery
• Critical Care Medicine

Background:

• Central venous access is a common procedure with known risks.
• Patients with severe pulmonary hypertension often have complex hemodynamic profiles.
• Tunneled central venous catheters are used for long-term access.

Observation:

• A case of inadvertent lymphatic disruption during tunneled central venous catheter insertion is presented.
• The patient had pre-existing raised left and right atrial pressures and severe pulmonary hypertension.
• This complication led to significant hemodynamic instability.

Findings:

• Lymphatic disruption is a rare but serious complication of central venous catheterization.
• The hemodynamic instability was directly linked to the lymphatic injury.
• This specific complication during tunneled catheter insertion appears to be previously unreported in medical literature.

Implications:

• Highlights a novel risk associated with central venous catheter insertion in specific patient populations.
• Emphasizes the importance of careful technique and awareness of potential lymphatic injury.
• Suggests the need for further investigation into the incidence and management of this rare complication.
