Mini-invasive Treatment of a Large Pseudoaneurysm of the Neck Related to Central Venous Catheter Placement: A Case Report

Mini-invasive Treatment of a Large Pseudoaneurysm of the Neck Related to Central Venous Catheter Placement: A Case Report

Chiara Palermo et al. Medicine (Baltimore).


Rationale: Central venous catheter (CVC) placement, particularly in emergency setting, may be associated with significant morbidity and mortality.

Patient concerns: A 33-year old woman with suspected pulmonary embolism, developed a pseudoaneurysm of the neck three days after a CVC placement in the right internal jugular vein, determining compression to adjacent neck structures.

Diagnoses: Computed tomography angiography and selective angiography demonstrated the presence of the pseudoaneurysm originating from the thyro-cervical trunk.

Interventions: The treatment was minimally invasive with endovascular exclusion first, and an open thrombectomy to resolve compressive syndrome two days later.

Outcomes: The color Doppler ultrasound confirmed the complete exclusion of the pseudoaneurysm with patency of the thyroid artery. A comprehensive review of literature on the risk factors and management of the unintended artery puncture was included.

Lessons: A correct technique under ultrasound guidance may reduce the incidence of unintended arterial injury during CVC placement. In patients with suitable anatomy and unfit for open repair, a minimally invasive approach provides a safe alternative to open surgery with excellent results.

Selective Angiography of the right thyro-cervical trunk confirmed the presence of the pseudoaneurysm (A, arrow) with active communication with the artery (B, arrow).

Endovascular repair of the pseudoaneurysm. A balloon expandable covered stent was released in the thyro-cervical trunk (A, arrow), and the post-procedure angiography confirmed the complete exclusion of the pseudoaneurysm and the patency of the inferior thyroid artery (B).

Mechanism of arterial injury. During the central venous catheter placement the needle was pushed too deep in the neck causing an accidental puncture of the thyro-cervical trunk (A, arrow). The unrecognized arterial injury in a patient with anticoagulation therapy slowly progressed to the formation of a giant pseudoaneurysm (B).
