Parasternal mediastinoscopy

The value of parasternal mediastinoscopy in staging bronchial carcinoma.

Computed tomography (CT) is the non-invasive staging procedure of choice for assessment of metastasis to mediastinal lymph nodes in patients with bronchial carcinoma. Cervical mediastinoscopy can provide histologic evidence of mediastinal spread to the peritracheal, tracheobronchial and subcarinal lymph nodes. Sub-aortic and para-aortic nodes cannot be sampled via this route. The present study ...

The Left Parasternal Impulse.

A lift or heave which is palpable at the left sternal edge is an accepted clinical sign of right ventricular hypertrophy. The parasternal impulse has been recorded in normal subjects and in patients with heart disease, and the results are described in this paper. A detailed description of the instrument used to make the recordings has already been published (Beilin and Mounsey, 1962). This inst...

Experience with Mediastinoscopy.

The parasternal defect.

The parasternal defect, or Morgagni hernia, may not be as rare as previous authors have stated. Brown (1952) gives its incidence as 3 % of diaphragmatic defects, and Harrington (1951) in a review of 334 cases of diaphragmatic hernia found it in 14 only. In the mass radiography units at Portsmouth and Southampton 30 cases have been picked up and a further three cases have been found in patients ...

Tuberculosis and mediastinoscopy.

Biopsy of lymph nodes at mediastinoscopy has been the method of diagnosis of tuberculosis in 14 patients; Mycobacterium tuberculosis was cultured from the nodes in nine cases, and in five there was histological evidence of the disease but cultural confirmation was lacking. All patients had radiographic abnormality of the superior mediastinum, and a frequent finding at mediastinoscopy was medias...
