Successful term pregnancy after selective arterial embolization of symptomatic arteriovenous malformation in the setting of gestational trophoblastic tumor.

Background: Patients with arteriovenous malformations (AVMs) are at risk for significant vaginal hemorrhage, and are traditionally managed surgically. In the patient desiring future fertility, conservative management via selective arterial embolization is a reasonable option. Only a few cases have been previously reported of successful pregnancy after this procedure in the setting of gestational trophoblastic disease (GTD).

Treatment of fibromuscular dysplasia and renal artery aneurysm with use of a stent-graft.

A Jostent stent-graft was placed in a renal artery with a focal stenosis and an associated aneurysm in a young patient with fibromuscular dysplasia. Arteriographic follow-up at 16 months showed that the stent-graft remained patent and the aneurysm was excluded.

Cost-effectiveness of percutaneous treatment of iliac artery occlusive disease in the United States.

Objective: The costs of percutaneous transluminal angioplasty and stent placement for iliac artery occlusive disease in the United States were assessed and the cost-effectiveness was evaluated.

Materials And Methods: Lifetime costs and quality-adjusted life expectancy were estimated using a Markov decision model for a hypothetic cohort of patients with life-style-limiting claudication caused by an iliac artery stenosis for whom a percutaneous intervention was indicated. Various percutaneous treatment strategies were evaluated, each consisting of an initial intervention followed by a secondary intervention.

Frequency of pulmonary embolism in patients with low-probability lung scan and negative lower extremity venous ultrasound.

Study Objectives: To define the prevalence of pulmonary embolism (PE) in patients who are undergoing pulmonary arteriography because of a high clinical suspicion for PE but who have had a low-probability lung scan and a negative lower extremity venous ultrasound examination.

Design: A retrospective review of the medical records of 365 consecutive patients who underwent pulmonary arteriograms for suspected PE was undertaken.

Results: Of the 365 pulmonary arteriograms, 62 were performed in patients with suspected PEs despite a low-probability lung scan and a negative lower extremity venous ultrasound examination.
