PowerPort Removal Surgery — How Fractured Catheters Are Retrieved

Why Fractured Catheter Fragments Must Be Removed

The standard of care for a retained intravascular catheter fragment is retrieval whenever technically feasible and procedurally safe for the patient. Reasons for retrieval include: prevention of bacterial colonization and biofilm formation that causes recurrent bloodstream infections; elimination of the arrhythmogenic (arrhythmia-causing) mechanical irritation of the right ventricular endocardium; prevention of cardiac perforation from fragment movement; removal of the thrombogenic foreign body that promotes clot formation; and elimination of the inflammatory stimulus that drives pulmonary vascular remodeling and pulmonary hypertension.

The decision to retrieve is individualized. A fragment clearly accessible in the right atrium or main pulmonary artery via percutaneous snare technique poses lower procedural risk and retrieval is strongly favored. A fragment deeply embedded in peripheral pulmonary arteries or already partially endothelialized (incorporated into vessel wall tissue) may pose higher retrieval risk than retention risk in elderly or medically fragile patients. Interventional cardiologists and cardiothoracic surgeons must weigh these considerations on a case-by-case basis. The fact that retrieval is required — whether percutaneous or surgical — is itself evidence of significant harm caused by the device defect.

Percutaneous Catheter-Based Retrieval

Percutaneous retrieval is performed by an interventional radiologist or interventional cardiologist in a cardiac catheterization laboratory using fluoroscopic guidance (live X-ray). A retrieval catheter is introduced via the femoral vein in the groin and advanced under fluoroscopic visualization to the fragment location. A snare device — a loop of wire — or a basket catheter is used to capture the fragment and pull it back through the venous system for removal through the femoral access sheath. The procedure typically requires conscious sedation and local anesthesia. Success rates for right-heart and main pulmonary artery fragments approach 70-90%, but peripheral pulmonary artery fragments are significantly more challenging and may require multiple attempts or specialized retrieval tools.

Open Surgical Retrieval

When percutaneous retrieval fails, is anatomically not feasible, or when the fragment has caused cardiac injury requiring direct surgical repair, open thoracic or cardiac surgery is required. The cardiothoracic surgeon performs a sternotomy (incision through the breastbone) or thoracotomy (incision between the ribs) under general anesthesia. In cases where the fragment is in the right ventricle or has perforated the cardiac wall, cardiopulmonary bypass (heart-lung machine support) may be required during the surgical repair. Recovery from open cardiac surgery involves ICU care, extended hospitalization (typically 5-10 days or more), and a prolonged recovery period of 4-8 weeks. Scarring, post-thoracotomy pain syndrome, and the psychological impact of major cardiac surgery are compensable damages in PowerPort litigation.

Documentation for Your Legal Claim

The retrieval procedure generates critical legal documentation: the interventional radiology or surgical operative report describing the fragment location, appearance, and retrieval method; the pathology report if the fragment was sent to pathology (which can confirm the polyurethane material and degradation features); and the procedural imaging (fluoroscopy, cine loops, or intraoperative photographs) showing the fragment in situ before retrieval. Patients and attorneys should ensure that all retrieval-related records are preserved, including the physical device fragment if it was retained by the hospital pathology department. This documentation is foundational to the causation evidence in a PowerPort lawsuit.
