Multiple Subsegmental Pulmonary Emboli Without Acute Cor Pulmonale

Multiple Subsegmental Pulmonary Emboli (MSSPE) is a type of pulmonary embolism (PE), which is a blood clot in the lungs. MSSPE occurs when there are multiple clots, each in a different part of the lung. These clots can block blood flow and cause damage to the lungs. MSSPE is often difficult to diagnose because the symptoms can be subtle.
