“…Additionally, injuries to neighboring structures such as aortic branches were noted, along with concomitant damage to major vessels such as the subclavian or splenic arteries observed in the reported cases [3]. In rare instances, traumatic pseudoaneurysms might involve cerebral arteries, like the anterior cerebral artery (ACA), due to avulsion from trauma [4]. In our patient's case, her traumatic AVP manifested as a saccular pseudoaneurysm/varix (Figure 2).…”

High-speed motor vehicle collisions (MVCs) often result in severe musculoskeletal, neurological, and vascular injuries. Among these, azygos vein pseudoaneurysms (AVPs) are a rare and potentially lifethreatening vascular complication. Our case study highlights an instance of an AVP arising from a highvelocity MVC, underscoring their critical significance in trauma scenarios. Additionally, this report delves into the complexities of managing AVPs, both traumatic and idiopathic, emphasizing the urgent need for intervention and the intricacies of their treatment.

“…In that report, a head CT scan showed SAH and a tBBA from the initial examination as in the present case, and the aneurysm was noted to enlarge over a short period of time. Most traumatic aneurysms are pathologically pseudoaneurysms, characterized by a short-term change in shape, [10][11][12] and the case described by Haji et al reflects these characteristics. The commonality between the present case and that of Haji et al is that the traumatic ICA aneurysm had already ruptured at the time of initial presentation.…”

Ruptured cerebral aneurysms that occur in the anterior wall of the internal carotid artery (ICA) are known as blood blister-like aneurysms (BBAs); they have been reported to account for 0.3% to 1% of all ruptured ICA aneurysms. In this report, we describe the treatment of an unusual traumatic BBA (tBBA) with high-flow bypass using a radial artery graft, which resulted in a favorable outcome. A 59-year-old female suffered from an acute epidural hematoma, traumatic subarachnoid hemorrhage, and traumatic carotid-cavernous sinus fistula (tCCF) after being involved in a motor vehicle accident. Her angiography results showed tCCF and a tBBA on the anterior wall of the right ICA. On the fourth day after injury, we found rebleeding from the tBBA and performed an emergency high-flow bypass using a radial artery graft with lesion trapping as a curative procedure for the tCCF and tBBA. Postoperatively, right abducens nerve palsy appeared, but no other neurological symptoms were noted; the patient was thereafter transferred to a rehabilitation hospital 49 days after injury. Traumatic ICA aneurysms commonly occur close to the anterior clinoid process, form within 1 to 2 weeks of injury, and often rupture around 2 weeks after trauma. This case was considered rare as the ICA was likely injured and bleeding at the time of injury, resulting in a form of tBBA; this allowed early detection and appropriate treatment that resulted in a good outcome.

“…It is estimated that 30% of all intracranial cerebral aneurysms involve the ACA. [ 7 , 24 ] Aggressive surgery should be planned to treat aneurysms caused by dissection because these aneurysms are associated with a high risk of rupture. Further, occlusion of the ACA due to traumatic intracranial artery dissection is uncommon.…”

Background: Cerebrovascular injuries (CVIs) are not usually considered in the differential diagnosis of sport-related head injuries (SRHIs). We encountered a rugby player with traumatic dissection of the anterior cerebral artery (ACA) after impact on the forehead. Head magnetic resonance imaging (MRI) with T1-volume isotropic turbo spin-echo acquisition (VISTA) was used to diagnose the patient. Case Description: The patient was a 21-year-old man. During a rugby tackle, his forehead collided with the forehead of an opponent. He did not have a headache or disturbance of consciousness immediately after the SRHI. On the 2nd day of illness, he had transient weakness of the left lower limb several times. On the 3rd day of illness, he visited our hospital. MRI revealed occlusion of the right ACA and acute infarction of the right medial frontal lobe. T1-VISTA revealed intramural hematoma of the occluded artery. He was diagnosed with acute cerebral infarction due to dissection of the ACA and was followed up for vascular changes with T1-VISTA. The vessel had recanalized and the size of the intramural hematoma had decreased 1 and 3 months after the SRHI, respectively. Conclusion: Accurate detection of morphological changes in cerebral arteries is important for the diagnosis of intracranial vascular injuries. When paralysis or sensory deficits occur after SRHIs, it is difficult to differentiate between concussion from CVI. Athletes with red-flag symptoms after SRHIs should not merely be suspected to have concussion; they should be considered for imaging studies.
