Summary
Rare ulnar artery aneurysms can result from repetitive tablet use, causing a rapidly expanding pseudoaneurysm. Prompt surgical repair, like end-to-end anastomosis, is crucial to prevent complications from this low-intensity trauma.
Area of Science:
- Vascular Surgery
- Trauma Surgery
- Hand Surgery
Background:
- Ulnar artery aneurysms are uncommon, often linked to hypothenar hammer syndrome from repetitive blunt trauma.
- Rapidly expanding ulnar artery pseudoaneurysms are exceptionally rare, typically resulting from penetrating injuries.
Observation:
- A unique case of a rapidly expanding pseudoaneurysm of the ulnar artery is presented.
- The pseudoaneurysm was caused by repetitive use of the hypothenar eminence supporting a tablet computer with a posterior notch.
- This notch was identified as a key factor in the injury's development.
Findings:
- Even low-intensity, repetitive trauma can injure the palmar ulnar artery.
- This injury mechanism can lead to the development of ulnar artery pseudoaneurysms.
- The case highlights an unusual cause of vascular injury in the hand.
Implications:
- Early diagnosis and surgical intervention, such as resection and end-to-end anastomosis, are vital for managing rapidly expanding ulnar artery pseudoaneurysms.
- This case broadens the understanding of potential causes for ulnar artery pseudoaneurysms beyond direct penetrating trauma.
- Awareness of this mechanism is important for clinicians treating hand and wrist injuries.

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...

01:15Bones of the Upper Limb: Ulna
11.2K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

646
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
