Percutaneous transluminal angioplasty of iliac arteries: the importance of functional studies.

Results of percutaneous transluminal angioplasty of 60 iliac arteries are presented, with a follow-up of 3 to 12 months. The patency rate at 1 year was 95% using the thigh-brachial index as the criterion and 86% with the ankle-brachial index. Study of the patients with an exercise test component improved the sensitivity of the evaluation, demonstrating that both indices tend to underestimate the functional improvement. The authors propose a simple, cost-effective way for practitioners to follow-up their patients after percutaneous transluminal angioplasty.

Giant cell arteritis presenting with aortic dissection: two cases and review of the literature.

Aortitis is the most serious location of the disease giant cell (temporal) arteritis (GCA). Aortic dissection or the rupture of an aortic aneurysm can be responsible for sudden death among patients with GCA. This report discusses two cases of GCA presenting with aortic dissection. One case had histologically proven giant cell aortitis. The second case was a fatal aortic dissection preceded by a stroke. We describe the main features of aortic dissection and aortitis during GCA, reviewing the existing literature on this subject, and focusing on the requirement of prospective aortic imaging studies to screen patients with this kind of location.

Recurrence of intravenous talc granulomatosis following single lung transplantation.

Advanced pulmonary disease is an unusual consequence of the intravenous injection of oral medications, usually developing over a period of several years. A number of patients with this condition have undergone lung transplantation for respiratory failure. However, a history of drug abuse is often considered to be a contraindication to transplantation in the context of limited donor resources. A patient with pulmonary talc granulomatosis secondary to intravenous methylphenidate injection who underwent successful lung transplantation and subsequently presented with recurrence of the underlying disease in the transplanted lung 18 months after transplantation is reported.

Prospective study of transbronchial biopsies in the management of heart-lung and single lung transplant patients.

A prospective study of 219 bronchoscopies in 54 heart-lung and in 2 single lung transplant recipients was undertaken over a 12-month period by a single operator. For histologic study, an average of 17.3 transbronchial biopsy specimens (range, 6 to 56) were taken from three lobes (or from two lobes and lingula of one lung). A further two specimens were taken for culture. The average procedure time was 14.4 minutes (SE 0.31). An estimate of the probability of rejection being missed, depending on the number of specimens taken and based on the method of Gilman and Wang, suggests 18 biopsy specimens are required to have 95% confidence of diagnosing rejection. Sensitivity for diagnosing rejection by histologic study of transbronchial biopsy specimens was 94%, and specificity was 90%. The simple grading of severity of rejection that was used was related both to the number of specimens demonstrating rejection and to the severity of graft airway mucosal inflammation seen at bronchoscopy. The major complication encountered, on 27 occasions, was bleeding of more than 100 ml. On no occasion did bleeding result in any long-term complication. Extensive transbronchial biopsy is a simple, relatively safe, and quick procedure, with a high sensitivity and specificity for diagnosing rejection and lung infection.
