The aim of this research was to validate transcription magnetic resonance (MR) imaging (MRI) for gene transcript targeting in acute neurological disorders in live subjects. We delivered three MR probe variants with superparamagnetic iron oxide nanoparticles (SPION, a T2 susceptibility agent) linked to a phosphorothioate-modified oligodeoxynucleotide (sODN) complementary to c-fos mRNA (SPION-cfos) or beta-actin mRNA (SPION-beta-actin) and to sODN with random sequence (SPION-Ran).

A patient with a dissecting hematoma of the internal carotid artery following chiropractic neck manipulation is described. This injury, apparently previously unreported in the literature, is thought to be caused by trauma to the artery by rotatory movement of the neck and pressure against the artery by the transverse process of C-2.

OBJECTIVE: To determine what effect wrist extension has on ulnar artery blood flow. DESIGN AND SETTING: This is a descriptive study performed at a private chiropractic clinic. SUBJECT SELECTION: Sixty-three ulnar arteries were examined from thirty-two volunteers, 15 men and 17 women, whose ages ranged from 21-75 yr. Only wrists that were asymptomatic and freely mobile were candidates for ulnar artery examination.

A 29-year-old woman died from a right hemispheric infarction caused by dissection and subsequent thrombosis of the internal carotid artery after chiropractic manipulations of the neck. Pathologic study of several arteries of muscular and elastic type revealed a mediolytic arteriopathy with widespread mucoid degeneration and cystic transformation of the vessel wall caused by segmental degeneration of smooth muscle cells of the tunica media.

PURPOSE: To document a case of central retinal artery occlusion after chiropractic treatment. METHODS: An 87-year-old man suffered a central retinal artery occlusion immediately after chiropractic neck manipulation. RESULTS: A magnetic resonance angiogram showed an atherosclerotic plaque in the ipsilateral carotid artery, which probably shed emboli during cervical joint mobilization. CONCLUSION: The carotid arteries should be approached carefully in patients with known or suspected atherosclerotic disease of the carotid arteries.

PURPOSE: Blunt injuries to the internal carotid artery (ICA) at the base of the skull are uncommon but potentially dangerous lesions whose management remains unclear. We report a new surgical approach of the intrapetrosal portion of the ICA that was used in six patients with the help of an ear, nose, and throat surgeon. METHODS: During a 70-month period, seven consecutive patients (four women, three men; mean age, 35.7 years; range, 21 to 59 years) were admitted, six after a motor vehicle accident and one after a cervical manipulation. All patients had a neurologic deficit.

A 50-year-old woman presented a sudden left occipital headache and a posterior circulation stroke after cervical manipulation for neck pain. Magnetic resonance imaging documented a left intracranial vertebral artery occlusive dissection associated with an ipsilateral internal carotid artery dissection with vessel stenosis in its prepetrous tract. This is the first reported case showing an associate vertebral and carotid artery dissection following cervical manipulation. Carotid dissection was asymptomatic and, therefore, its incidence may be underestimated.

PURPOSE: To report a case of Horner's syndrome and dissection of the internal carotid artery after chiropractic manipulation of the neck. METHODS: Case report. A 44-year-old woman with no prior ocular or vascular history presented with severe right-sided head and neck pain, ptosis, and miosis following chiropractic treatment for a strained right shoulder muscle. RESULTS: Magnetic resonance angiography of the neck and brain revealed a dissection of the right internal carotid artery as well as a suggestion of subtle dissection in the right vertebral artery.

BACKGROUND: Cervical manipulation is used millions of times every year. Concern about cerebrovascular accidents (CVAs) is common, but actual cases are rarely reported. Premanipulative tests are presumed to identify patients at risk of CVA. In an earlier study we found no significant changes in the vertebral artery blood flow of patients with a positive premanipulative test with different head positions. Consequently, we questioned whether there is a role for premanipulative testing to identify patients at risk of CVAs.

Aneurysms of the extracranial portion of the internal carotid artery are rare, particularly in young patients. They usually develop following trauma, or secondary to infection involving the parapharyngeal space that extends to the vessel wall. This is a case of an internal carotid artery aneurysm presenting acutely following chiropractic neck manipulation with hypoglossal and glossopharyngeal nerve palsy. The imaging findings and subsequent operative management are described.
