Extracranial carotid artery dissection may manifest as arterial stenosis or occlusion, or as dissecting aneurysm formation. Anticoagulation and/or antiplatelet therapy is the first-line treatment, but because it is effective and less invasive than other procedures, endovascular treatment of carotid artery dissection has recently attracted interest. We encountered two consecutive cases of traumarelated extracranial internal carotid artery dissection, one in the suprabulbar portion and one in the subpetrosal portion. We managed the patient with suprabulbar dissection using a self-expandable metallic stent and managed the patient with subpet-rosal dissection using a balloon-expandable metallic stent. In both patients the dissecting aneurysm disappeared, and at follow-up improved luminal patency was observed.

Carotid artery dissection is a significant cause of stroke in young patients. It may be asymptomatic and go undiagnosed, or minimal transient manifestations may follow, commanding a higher index of suspicion than ordinarily exists to avoid misdiagnosis. Reported herein is a 27-year-old man who suffered extracranial internal carotid artery dissection while practicing a Brazilian Jiu-Jitsu submission maneuver. The patient's condition suddenly deteriorated one week later due to distal embolization and stroke. Despite endovascular treatment, with stenting of the cervical carotid artery, neurologic deficits remained. Of note, the objective in martial arts, which is to kill or incapacitate, has yet to be fully tempered in transitioning to sport. Brazilian Jiu-jitsu, a relatively new and fast-growing form of martial art, places emphasis on submission maneuvers. Related injuries are not common knowledge and are poorly described in the literature. This account is intended to shed light on the risk of this discipline. Through education and improved supervision, vascular injuries of this nature and the potentially lethal or disabling consequences may thus be prevented in young athletes.

The incidence of spontaneous recanalization after traumatic internal carotid artery occlusion is very rare. We have experienced a case of spontaneous recanalization after a traumatic internal carotid artery occlusion. A 5-year-old boy developed contra-lateral hemiparesis and dysphasia after a blunt injury on the head and neck. He had a complete left internal carotid artery occlusion which was diagnosed through angiography. We treated the patient with an antiplatelet agent and rehabilitation. Six months later, he regained motor power of right extremities, language ability, and revisualization of internal carotid artery on the follow-up magnetic angiography. We confirmed a recanalization of injured internal carotid artery on the conventional cerebral angiography which was performed one year later. We suggest conservative treatment with serial angiographic studies as a possible option of traumatic internal carotid artery occlusion even though there is hemodynamic instability.

Surgical resection is the only option for the treatment of carotid body tumor. The tumor is characterized by its hypervascularity and adherence to the carotid artery. Neurovascular injuries have been a well known surgical complication during the procedure. We experienced a case of carotid artery injury during the resection of carotid body tumor and which was reconstructed with interposition graft using autogenous vein. Vascular injury as a complication during the resection of carotid body tumor was reviewed.

OBJECTIVETo discuss the diagnosis and management of traumatic carotid cavernous fistula (TCCF).

METHODSIn all 15 patients with TCCF confirmed by angiography, 8 patients got early diagnosis and cure. With Seldinger technique adopted in the puncture of femoral artery, Magic 3 F-1.8 F BD catheters combining with balloon were used to embolize the fistula or the internal carotid artery.

RESULTSEarly diagnosis and cure were achieved in 8 patients within one week and no sequelae occurred. Seven patients with delayed diagnosis who were cured beyond one week had some sequelae such as hypopsia in 5 cases, incomplete oculomotor paralyses in 3 and incomplete abducent paralyses in 2. Among all the 15 cases, the internal carotid artery was preserved in 12 cases accounting for 80%. Occluding the fistula with sacrifice of the internal carotid artery was performed in 3 cases and no repatency of the fistula occurred by following up beyond three months.

CONCLUSIONSThe preferred therapy for TCCF is to occlude the fistula using detachable balloon. The diagnosis and treatment for TCCF can significantly reduce occurrence rate of the complications and sequelae.

There are many vital structures in the neck, but they are not protected by bone. The neck is vulnerable to injury, and difficult to evaluate the extent of injury. Especially, penetrating neck wounds are potentially dangerous and require emergency treatment. A 56-year-old man with a penetrating neck injury by a grass cutter fragment was transferred from another hospital. There were no immediate life-threatening signs or symptoms. Carotid artery injury was suspected in the computed tomography scan. Emergent exploration was implemented by vascular surgery to remove the grass cutter fragment that had penetrated the left common carotid artery. We report a rare case of common carotid artery penetrating injury that was treated without any complications.

Penetrating neck injuries are potentially dangerous and require emergent management because of vital structures in the neck. A 35-year-old woman was transferred to the hospital with massive bleeding in her mouth and lacerations of her neck after the stab injuries. Contrast-enhanced computed tomography (CT) and angiography revealed a leakage at the pharyngeal portion of the right internal carotid artery. Emergent endovascular treatment was undertaken by using the stent technique. The leakage was completely occluded immediately after the procedure. There was no complication. The stent technique was safe and effective for the treatment of zone III carotid artery stab injuries.

Blunt carotid artery injury is uncommon, yet not rare. However, it is often underdiagnosed because of inconsistent early symptoms or masking by the presence of coexisting brain and spinal injuries. The delay between the accident and the onset of cerebral ischemic symptoms is variable and has been reported to range from minutes to ten years. However, to our knowledge, there has been no report on a case presented with delayed intracerebral hemorrhage 25months after blunt carotid artery injury. We report on a case with discussion of supporting evidence and possible mechanisms.
