Pseudoaneurysm; Stone chip injury; Subclavian artery; Pulsatile swelling
A pseudo aneurysm, also known as a false aneurysm, is a hematoma that forms as a result of a leaking hole in artery. Hematoma was contained by the surrounding tissues. Also it must continue to communicate with the artery to be considered a pseudo aneurysm. Post stab injury subclavian artery pseudoaneurysm is rare entity with great significance because of risk of complications like thrombosis, rupture, gangrene, limb loss and should be operated early whenever diagnosed. Our case report has 18 year male patient with history of accidental stone chip injury to left supraclavicular region followed by pulsatile swelling after five days due to subclavian artery pseudoaneurysm. We excised pseudoaneurysm with direct closure of opening in subclavian artery and removal of stone chip.
According to the literature data, post traumatic pseudoaneurysm is rare . Most common site is common femoral artery, followed by radial and brachial artery but subclavian artery is very rare because trauma to it is rare. Incidence of complications associated with such pseudoaneurysm is estimated around 2–6% . We present a case of the patient in whom pseudoaneurysm of left subclavian artery developed after five days of accidental stone chip injury and was successfully treated by surgical excision of pseudoaneurysm and removal of stone chip with direct closure of opening in subclavian artery.
A 18 -years-old male patient was admitted at our Institute with history of accidental injury to left supraclavicular region lateral side by stone chip while walking nearby to stone chipper (Figure 1A). After five days the patient noticed gradually increasing pulsatile swelling at injury site. Clinical examination revealed presence of pulsating mass at injury site of 12 by 12 cm in diameter. Left brachial, radial and ulnar artery pulsations are palpable. Chest X ray showed radiopaque stone chip below left clavicle (Figure 1B). Ultrasonography and CT angiography verified presence of pseudo aneurysm connected by opening in second part of left subclavian artery (12 cm in diameter) (Figure 2).
