Recurrent cutaneous decompression illness after PFO device implantation: a case report.
1University of Antwerp, Wilrijk, Belgium.
Summary
Patency of the foramen ovale (PFO) increases decompression illness (DCI) risk in divers. This case shows DCI can recur due to a PFO even after surgical closure, highlighting ongoing risks.
Area of Science:
- Cardiovascular Science
- Diving Medicine
- Hyperbaric Physiology
Background:
- Patency of the foramen ovale (PFO) is a known risk factor for decompression illness (DCI) in scuba divers.
- Divers with PFO may experience DCI despite adherence to standard decompression protocols, often referred to as an "undeserved hit."
- Percutaneous closure of PFO is a discussed intervention following DCI events.
Observation:
- This report details a scuba diver who experienced a recurrent cutaneous DCI.
- The DCI occurred four years after the initial treatment for a PFO with a percutaneous occluder device.
Findings:
- The recurrent DCI was attributed to a recurrent PFO, indicating potential device failure or incomplete closure.
- This case challenges the long-term efficacy of percutaneous PFO closure in preventing DCI in certain high-risk individuals.
Implications:
- The findings suggest that PFO recurrence after closure is possible and can lead to DCI.
- Further research is needed to understand the long-term durability of PFO closure devices and identify optimal management strategies for divers with PFO.
- This case underscores the complexity of managing PFO in divers and the need for individualized risk assessment.

1.1K
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

01:10PPE Use in Healthcare Settings II: Doffing
1.7K
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
