Brainstem infarction in a patient with internal carotid dissection and persistent trigeminal artery: a case report

<p>Abstract</p> <p>Background</p> <p>The primitive trigeminal artery (PTA) is the most commonly described fetal anastomosis between the carotid and vertebrobasilar circulations.</p> <p>Case presentation</p> <p>We report a 42-year-old patient presenting with internal carotid dissection, and imaging features of brainstem infarction.</p> <p>Conclusion</p> <p>Based on the imaging studies we presume occlusive carotid dissection with extensive thrombosis within a persistent trigeminal artery as the cause of this brainstem ischemia.</p

Sciatic neuropathy associated with persistent sciatic artery.

Persistent sciatic artery is a congenital vascular anomaly of the arterial supply to the lower extremity. Thrombosis, distal embolization, aneurysmal dilatation, and rupture of this vessel with compression of the sciatic nerve have been recorded. Although rare in occurrence, complications of persistent sciatic artery should be included in the differential diagnosis of sciatic neuropathy. We present a case of an acute sciatic neuropathy secondary to pseudoaneurysm formation of a persistent sciatic artery. We demonstrate the diagnostic usefulness of magnetic resonance imaging

Dissections after childbirth

The occurrence of spontaneous internal carotid or vertebral artery dissection after childbirth remains rare. To our knowledge, seven cases of arterial dissection in the postpartum period have been described in the literature as single case reports. We report four additional cases of internal carotid and vertebral artery dissection in the puerperal period, documented by angiography. Physicians should consider the possibility of arterial dissection in any young patient presenting with acute ischemic stroke, including women in the postpartum period. The availability of modern noninvasive ultrasound and imaging techniques may result in earlier diagnosis and facilitate identification of this condition
