Coronary artery vasospasm (CAV) is a reversible, transient form of vasoconstriction with clinical manifestations ranging from stable angina to acute coronary syndromes (ACS). Vasospasm epicardial arteries or associated micro-vasculature can lead total subtotal occlusion and has been demonstrated in nearly 50% patients undergoing angiography for suspected ACS. The mechanism CAV described literature, but subgroup presenting intracranial hemorrhage, it appears be multifactorial. These tend have...

Traumatic carotid artery thrombosis is uncommon and it usually results from penetrating injuries less commonly secondary to blunt trauma. It can lead delayed clinical presentation, which leads delay in the diagnosis. Soldiers combat scenario also present with such an illness, varied modes of injuries. Our case illustrates unusual cause thrombosis.Our patient a 37-year-old soldier who developed neck pain headache following 5 km training run rifle on shoulder subsequently left upper limb...
