Summary
Traumatic internal mammary artery disruption causes a localized hematoma, not a pleural effusion. This previously undescribed injury can result from blunt or penetrating trauma.
Area of Science:
- Vascular Surgery
- Trauma Surgery
- Diagnostic Imaging
Background:
- Internal mammary artery (IMA) injuries are rare.
- Previous reports have not detailed IMA disruption leading to extrapleural hematomas.
Purpose of the Study:
- To describe a previously unreported consequence of traumatic internal mammary artery injury.
- To characterize the presentation and diagnosis of IMA disruption.
Main Methods:
- Review of ten cases with traumatic IMA disruption.
- Angiographic verification of injury and hematoma formation.
Main Results:
- Traumatic IMA disruption results in well-circumscribed extrapleural hematomas.
- Haemothorax is not a typical finding in these cases.
- Both blunt and penetrating trauma can cause IMA disruption.
Conclusions:
- Traumatic IMA disruption is a distinct clinical entity.
- Extrapleural hematoma is the characteristic finding.
- Angiography is crucial for diagnosis.

01:12Arteries of the Upper Limbs
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
