Rifled carotid: Internal carotid artery thrombosis from prolonged carrying of a military rifle.

BACKGROUND

Traumatic carotid artery thrombosis is uncommon and it usually results from penetrating injuries and less commonly secondary to blunt trauma. It can lead to delayed clinical presentation, which leads to delay in the diagnosis. Soldiers in combat scenario also can present with such an illness, which results from varied modes of injuries. Our case illustrates an unusual cause of carotid thrombosis.

CASE PRESENTATION: Our patient is a 37-year-old soldier who developed neck pain and headache following a 5 km training run with rifle on the shoulder and subsequently developed left upper limb weakness and evaluation revealed extracranial right internal carotid thrombosis. He was managed with anticoagulants and antiplatelets with complete resolution of the thrombosis and complete recovery of the weakness.

CONCLUSION

Blunt trauma to the neck in the form of carrying a rifle for a prolonged duration can result in injury to the carotid vessels leading to delayed neurological presentation. Educating the troops regarding such a mode of illness will prevent such a catastrophic nature of vascular injury resulting in ischaemic stroke.
