Pulmonary arteriovenous fistula in a patient with Rendu-Osler-Weber syndrome

Pulmonary arteriovenous fistula (PAVF) is an abnormal connection between pulmonary arteries and veins. Patients with PAVF may have the Rendu-Osler-Weber syndrome, a disease transmitted by autosomal dominant mechanisms. Here we describe a case of PAVF in a 56-year-old woman, who was admitted to our department because of dyspnea, hemoptysis, and a mass in the left lower lung found on chest X-ray. The diagnosis of PAVF was suspected according to clinical and physiological criteria and confirmed by magnetic resonance imaging of the chest. The PAVF was removed by left lower lobectomy. Anamnestic and clinical investigations of the patient's relatives led to the diagnosis of the Rendu-Osler-Weber syndrome.

[Traumatic lesions of the diaphragm]

The authors report their experience of 21 cases of post-traumatic hernias of the diaphragm. On the basis of the results obtained by discussion of etiologic, diagnostic and therapeutic patterns they make at the conclusion that the high mortality, associated with diaphragmatic hernias, can be reduced only with a short time of diagnosis and a prompt surgical treatment of the associated lesions.

Descending necrotizing mediastinitis. Surgical drainage and tracheostomy

OBJECTIVE

To outline the most appropriate treatment of descending necrotizing mediastinitis.

DESIGN

Case series.

SETTING

General community, institutional practice, hospitalized care.

PATIENTS

Five consecutive cases of descending necrotizing mediastinitis that were treated at our institution from 1983 to 1995. Selection criteria included clinical manifestations of severe cervical infection, characteristic radiographic features, documentation of the mediastinal infection at operation, and establishment of the relationship of the oropharingeal infection with the mediastinal process. Cases of mediastinitis due to perforation of the cervical esophagus were excluded. A cervicothoracic computed tomographic scan was obtained in the last 4 patients on admission. In the first case, computed tomographic scanning was not yet available at our institution.

INTERVENTIONS

All patients underwent drainage of the cervical infection through a cervical incision. Mediastinitis was drained by thoracotomy in 2 patients, since the lower mediastinum was involved, whereas 3 patients underwent cervicomediastinal drainage alone. Tracheostomy was performed in 2 patients.

RESULTS

All patients survived, with a short hospital stay (mean, 35 days).

CONCLUSIONS

Cervicomediastinal drainage is adequate when the descending mediastinitis is limited to the upper mediastinum. Thoracotomy has to be performed only when the process has diffusely spread below the carina. Early diagnosis is crucial, and we strongly recommend a cervicothoracic computed tomographic scan in every patient with deep cervical infection. We consider tracheostomy not always necessary. Adequate early drainage, with the cervical wounds left open, and antibiotic and anti-inflammatory therapy should prevent upper airway obstruction.
