1/314. fibromuscular dysplasia involving coronary arteries--a case report.

    The authors report a young patient with fibromuscular dysplasia involving multivessels including coronary arteries. If young patients have chest pain on effort, fibromuscular dysplasia of coronary arteries must be considered. As fibromuscular dysplasia is a chronic progressive disease and some cases progress rapidly in a few months, careful follow-up and comprehensive medical management may be necessary in such patients.

2/314. Bilateral fibromuscular dysplasia in identical twins.

    fibromuscular dysplasia is an arterial occlusive disorder that often affects the renal arteries and leads to renovascular hypertension. The cause of this disease is unknown. However, the occurrence in siblings suggests that genetic factors may play a role. We describe two cases involving hypertensive identical twins with fibromuscular dysplasia of the renal arteries. This unique clinical case reinforces a possible hereditary nature of this arterial occlusive disorder. ( info)

3/314. Case report of fibromuscular dysplasia presenting as stroke in a 16-year-old boy.

    fibromuscular dysplasia of the carotid artery is uncommon, but not rare. Although the true incidence and prevalence of the disease are not known, reported figures in adults range between 0.6% by angiography and 1.1% at autopsy. Most case reports of stroke caused by carotid fibromuscular dysplasia describe findings in adult subjects, although there are a few reports of the disease in children. In the present case, we describe a 16-year-old boy with fibromuscular dysplasia confined to one internal carotid artery and its branches, and in whom the disease declared itself by stroke. This case serves as a basis for considering diagnostic methods, treatment options, and future research in pediatric patients with cerebrovascular disease caused by fibromuscular dysplasia. ( info)

4/314. An unusual type of combined aortic coarctation due to fibromuscular dysplasia.

    A 3-year-old patient is described with an unusual form of co-arctation due to hypoplasia of the transverse arch and fibromuscular dysplasia involving a long segment of the thoracic aorta. Surgical repair required resection of the aorta from the distal transverse arch to the mid-descending thoracic aorta, and replacement with a 16-mm Dacron interposition graft. This case demonstrates the importance of preoperative evaluation of the entire aorta in the presence of co-arctation due to fibromuscular dysplasia. ( info)

5/314. Autotransplantation and stent implantation for bilateral renal artery fibromuscular dysplasia.

    A 36-yr-old male was found to have renovascular hypertension due to an occluded right renal artery and 70% stenosis in the left renal artery, caused by fibromuscular dysplasia. The right kidney was supplied by collateral blood flow, and secreted more renin than the left kidney. Two differential therapeutic approaches were taken: autotransplantation for the right kidney and percutaneous transluminal renal angioplasty followed by stent implantation for the left. The renovascular hypertension was treated with these therapies, preserving renal function in this patient. ( info)

6/314. Successful Wallstent implantation for extensive iatrogenic renal artery dissection in a patient with fibromuscular dysplasia.

    PURPOSE: To describe a case of renal artery stenosis with fibromuscular dysplasia (FMD) and extensive iatrogenic dissection treated with Wallstent implantation. methods AND RESULTS: An 83-year-old woman with a history of coronary artery disease and hypertension presented at another facility with exertional angina and poorly controlled hypertension. Renal arteriography uncovered a critical right renal artery stenosis with severe FMD. However, angioplasty resulted in extensive dissection of the renal artery, for which the patient was referred to our institution. The renal artery was recanalized via the left brachial approach with restoration of flow using a Wallstent and a Palmaz stent. The patient's blood pressure was controllable after this procedure, and follow-up duplex imaging with flow velocities at 6 months showed patent right renal artery stents. CONCLUSIONS: Owing to its length and flexibility, the Wallstent endoprosthesis was a useful treatment modality in this case of extensive renal artery dissection. ( info)

7/314. fibromuscular dysplasia of the external iliac artery.

    A 47-year-old female with fibromuscular dysplasia of both external iliac arteries was treated by percutaneous balloon catheter angioplasty. The immediate result was unsatisfactory. On discharge from hospital, the patient was only able to walk one kilometer, and had reduced ankle:arm blood pressure indices. Conservative treatment with anticoagulants for three months, followed by ticlopidine, and exercise for six months led to complete recovery. ( info)

8/314. A case of sudden death caused by fibromuscular dysplasia.

    After sudden unexpected death in a previously healthy 42 year old woman, necropsy examination showed myocardial infarction caused by occlusion of a vital coronary artery by fibromuscular dysplasia. This is a rare arterial disease with a clinical onset usually in the third or fourth decades of life. The aetiology is not fully understood but since it affects vital (cerebral and coronary) blood vessels it often has fatal consequences. ( info)

9/314. Thrombosed giant coronary artery aneurysm presenting as an intracardiac mass.

    Giant coronary artery aneurysms are rare in adults and are usually found in association with Kawasaki's disease arising in childhood. We report a case of a thrombosed giant right coronary artery aneurysm presenting as an intracardiac mass detected after inferior wall myocardial infarction. Histologic analysis indicated that fibromuscular dysplasia was the underlying cause of the aneurysm. ( info)

10/314. Pulmonary arterial fibromuscular dysplasia: a rare cause of fulminant lung hemorrhage.

    Arterial fibromuscular dysplasia (FMD) represents a collection of noninflammatory and nonatherosclerotic vascular diseases with a poorly understood etiology. Classically occurring in renal and cerebral arteries, this entity has also been reported in coronary, carotid, and other medium and small arteries. One case occurring in the pulmonary vasculature has been reported. Fatal hemothorax and lung hemorrhage have multiple causes, including other vascular malformations and connective tissue disorders; however, cases of pulmonary FMD are exceedingly rare. We report what appears to be the second such association, occurring in a 69-year-old man. The patient presented with a 3-week history of increasing dyspnea, fatigue, and productive cough; 3 days of increasing back and chest pain; and syncope. Chest radiograph showed a "white-out" of the left lung. The patient died shortly after admission from a fulminant respiratory disease of undetermined etiology. At autopsy he was found to have a massive left hemothorax resulting from an unsuspected pulmonary arterial fibromuscular dysplasia. ( info)
