Traumatic superficial temporal artery aneurysm

Traumatic aneurysm of the superficial temporal artery is an uncommon lesion. Two cases of post-traumatic superficial temporal artery aneurysm are presented.     

Traumatic aneurysm of the middle cerebral artery

The authors report a case of giant traumatic true aneurysm of the middle cerebral artery. A review of the related literature and a general revision are presented.     

Traumatic aneurysm of the peripheral cerebral artery]

Two cases of traumatic aneurysm of peripheral cerebral artery were reported. Case 1. A 6-year-old girl was severely injured on her head by automobile accident. Plain skull films showed depressed fracture in the left frontal region. Left common carotid angiogram 25 days after the injury revealed small aneurysm of a cortical branch of the anterior cerebral artery. Cranioplasty and removal of the aneurysm was performed. Postoperative course of this patient was uneventful. Case 2. A 4-year-old girl fell downstaris and struck her left temporal region. On admission, she was unconscious and plain skull films showed multiple linear fractures. No aneurysm was demonstrated in the right common carotid angiogram immediately after the head trauma. Since her general condition gradually improved, she discharged 23 days after the head trauma. 63 days after the injury, she developed sudden onset of severe headache, vomiting, and status epilepticus. Right common carotid angiogram showed a large aneurysm arising from a branch of right pericallosal artery at the free edge of the falx. Parent artery of the aneurysm was clipped. Postoperatively, the patient made uneventful recovery. 60 reported cases of traumatic aneurysm of peripheral cerebral artery were reviewed and analyzed in etiology, diagnosis, clinical course, treatment and pathogenesis.     

Traumatic aneurysm of the occipital artery secondary to paintball injury

Paintball is an "extreme sport" that has been steadily growing in popularity since the early 1980s. Although this activity is considered recreational, there are a number of inherent dangers associated. Most notably, the number of head and neck injuries due to paintball participation has been increasing in recent years. In this paper we present the first reported case of occipital artery traumatic pseudoaneurysm resulting from a paintball accident. The presentation, diagnosis and intraoperative findings are detailed. A discussion including a review of the literature is also presented. The authors recommend a re-evaluation of guidelines within the paintball sporting industry, including improvements in protective equipment.     

Traumatic aneurysm of the cortical branch of the middle cerebral artery

A 22-year-old patient is described in whom sudden deterioration developed on the 9th day after severe craniocerebral trauma. Left common carotid angiography demonstrated an aneurysm on a cortical branch of the middle cerebral artery and subdural haematoma. During the operation the aneurysm was excluded from the circulation.     

外伤性颞浅动脉瘤（附7例分析）

目的探讨外伤性颞浅动脉瘤的诊断和治疗方法。方法回顾性分析7例外伤性颞浅动脉的临床表现、手术方法和治疗结果。所有病例均因外伤后额部或颞部进行性增大肿物就诊,无颞浅动脉瘤破裂出血病例,全部病例在局部麻醉下切除动脉瘤囊肿,其中1例为分又部梭形动脉瘤。结果病理报告均为假性动脉瘤,动脉外膜存在。无术后头皮缺血、坏死发生。结论根据外伤史、颞浅动脉走行上搏动性肿物的特点,颞浅动脉瘤即可明确诊断。动脉壁中膜弹力层断裂,局部因动脉血流搏动冲击膨出形成可能是颞浅动脉瘤形成的另一个机制。动脉瘤切除术是治疗颞浅动脉瘤的有效方法。     

Traumatic intracranial aneurysm: a brief review.

Traumatic intracranial aneurysms are uncommon and represent fewer than 1% of all cerebral aneurysms. They may develop after blunt or penetrating head injuries and can present both diagnostic challenges and surgical difficulties. Because traumatic aneurysms are fragile and prone to rupture, early diagnosis with cerebral angiography and prompt treatment are essential. We present two patients with traumatic aneurysms and discuss their aetiology, classification, clinical presentations, diagnosis, and treatment options.     

Traumatic distal anterior cerebral artery aneurysm in a child: a case report

Traumatic intracranial aneurysms constitute less than 1% of all intracranial aneurysms. A case of traumatic distal anterior cerebral artery aneurysm in 18 months old child, treated successfully by microsurgical excision of aneurysm is being reported, along with review of the literature.     

Postpartum dissecting aneurysm of the basilar artery.

BACKGROUND AND PURPOSE: Dissecting aneurysms arising from the vertebrobasilar complex are rare and difficult to manage. More of their natural history needs to be known before treatment can be optimized. CASE DESCRIPTION: We report a postpartum dissecting aneurysm of the right vertebrobasilar artery in a 31-year-old woman that was confirmed by angiographic identification of a double lumen. The intracranial segment of the right vertebral artery was thrombosed proximal to the aneurysm. The patient, managed conservatively, recovered well and, when reexamined 2 months later, was found to be neurologically intact. A repeat angiographic study at that time demonstrated that the aneurysm had resolved. CONCLUSIONS: Proximal occlusion may have protected the aneurysm from rupture and further dissection, thereby making surgery unnecessary.     

Traumatic arteriovenous fistula of the superficial temporal artery.

Arteriovenous fistula of the scalp is relatively rare. The superficial temporal artery is particularly vulnerable to trauma due to its long and relatively exposed course in the scalp. We report a traumatic arteriovenous fistula of the superficial temporal artery treated by complete surgical excision and review the literature with regard to etiology, clinical manifestations, pathogenesis, diagnosis and management of these unusual lesions.     

Confabulation following aneurysm of the anterior communicating artery.

Nine subjects with aneurysms of the anterior communicating artery (ACoA) and 17 subjects with other intracranial hemorrhages (ICH) were evaluated for confabulatory responses under two naturally occurring conditions: (1) when subjects were not oriented to person, place, month and year, (2) when subjects were fully oriented. Confabulation was observed in all 9 of ACoA patients both during disoriented and oriented periods. In contrast, 7/17 of the other ICH patients showed signs of confabulation while disoriented, whereas only one continued to display confabulatory tendencies while fully oriented. Confabulation was more severe in the ACoA group. These data suggest that the confabulation observed in the other ICH group may be secondary to an acute confusional state while the prolonged confabulation in ACoA patients may be a manifestation of a more primary cerebral disorder.     

Postpartum dissecting aneurysm of the posterior cerebral artery.

Intracranial dissecting aneurysm may cause subarachnoid hemorrhage (SAH) or infarction, and postpartum dissecting aneurysm is rare. A 30-year-old 6 days postpartum woman presented with posterior cerebral artery (PCA) dissection evolving dramatically over a short period. She had been well until 6 days after delivery when she suffered sudden onset of headache, vomiting, and unconsciousness. CT scan demonstrated SAH and digital subtraction angiography (DSA) revealed a fusiform dilatation of the left PCA (P3/P4 segment). The initial diagnosis was ruptured dissecting aneurysm, and conservative management was recommended in the acute period. DSA showed smoothening of the vascular wall 6 days after onset, and obliteration of the left P3/P4 segment was observed 13 days after onset. She was discharged without neurological deficits 26 days after onset. Postpartum SAH due to dissecting aneurysm of the PCA is rare, but should be considered in the differential diagnosis of postpartum headache.

Frequency of the callosomarginal artery and proposal of a hypothesis with regard to its phylogenetic significance

The neuroanatomic study of the callosomarginal artery was performed by simple and careful dissection in 52 human brains. The observation was made with stereoscopic magnifying glass. The results were the following: the callosomarginal artery was present in 36.6% (19/52) of the cases on the right hemisphere and 29% (15/52) on the left hemisphere; unilateral absence on those hemispheres was of 17.3% (9/52) and 25.0% (13/52), respectively; bilateral absence was of 46.1% (24/52). The register of the presence or absence of the artery was based on proposed criteria by Moscow and col. With regard to phylogenetic signification one has considered the hypothesis that the development of the callosomarginal artery possibly was closely related with a structural and physiological expansion of the neocortex in man.
