External iliac artery dissection secondary to endofibrosis in a cyclist

Endofibrosis of the external iliac artery is an uncommon disease affecting primarily young, otherwise healthy, endurance athletes. Thigh pain during maximal exercise with quick resolution postexercise is characteristic of the so-called cyclist's iliac syndrome. We report an unusual case in which the typical endofibrotic plaque was accompanied by dissection of the external iliac artery. The patient was treated surgically with excision of the affected artery segment and placement of an interposition graft. This case highlights an unusual finding in association with external iliac artery endofibrosis and provides an opportunity to briefly review the literature on the subject

Congenital absence of the external carotid artery: Atherosclerosis without a bifurcation

AbstractWe report the case of a patient with congenital absence of the external carotid artery in whom we performed a carotid endarterectomy. The radiographic features and operative findings are presented. Four similar cases previously reported in the literature are reviewed. A comment on the pathophysiology of atherosclerosis at the carotid bulb in the absence of a bifurcation and a brief discussion on the possible embryologic explanation of this anomaly are discussed.

Ischemic Colitis Secondary to Ergotamine Use: A Case Study

A 48-year-old woman with a history of chronic migraines, initially admitted for inpatient management of intractable migraine headaches, developed new onset abdominal pain, hypotension, and diarrhea on hospital day number ten. In our institution's headache unit, patients are treated by a multidisciplinary approach, including individualized drug therapy based on diagnosis and previous response to therapy. Given the patient's hypotension and clinical appearance, she was transferred to the intensive care unit and treated for septic shock and metabolic acidosis. A bedside colonscopy revealed diffuse ischemic colitis. Final pathology after colon resection showed widespread, transmural necrosis of the colonic wall. We review the pathophysiology of ergotamine use and its potential association with ischemic colitis

Small Bowel Ischemia in a Sickle Cell Patient

We report a case of small bowel ischemia secondary to sickle cell disease. Acute bowel ischemia is an uncommon presentation of patients with sickle cell disease. Historically, only a handful of cases have been reported. We also provide a summary of the literature relevant to sickle cell patients with acute bowel ischemia
