Classification of pulmonary lesions into central and peripheral with a template applied on chest X-ray.

To facilitate the understanding of the anatomical localization of pulmonary lesions and to optimize diagnostic evaluation, a template was designed which, on conventional chest X-rays, could be employed to discriminate between central and peripheral pulmonary lesions. The term 'central' implies that the lesion should be visible in the tracheobronchial tree through a fibre-optic bronchoscope, and the term 'peripheral' suggests that the lesion is not visible through a bronchoscope. In 20 patients examined by fibre-optic bronchoscopy, the bronchoscope was wedged into four pre-selected segmental bronchi in each lung. Using fluoroscopy, the tip of the bronchoscope was marked out on the skin with leadshot. On subsequent chest X-rays, with posterior-anterior and right lateral views, the distances and angles of the markings of the bronchi were mapped out in relation to the main carina. These data were used to design the template.

Parapharyngeal abscess and torticollis.

The combination of a parapharyngeal abscess and torticollis in an adult, due to a spastic contraction of the sterno-cleido-mastoid muscle is an extremely rare condition. We have recently been exposed to such case, in which it was very difficult to make the diagnosis and where CT of the neck gave us the answers without any difficulty. The indication for CT at an early stage in unexplained neck infections is stressed.

Thrombectomy of acute iliofemoral venous thrombosis during pregnancy.

Acute iliofemoral venous thrombosis is six times more frequent among pregnant than nonpregnant women. The disease is serious because of the risk of pulmonary embolism. The treatment of choice with regard to prevention of post-thrombotic disorders is controversial. Pregnant women represent a therapeutic problem because thrombolysis is hazardous to the fetus. We have performed thrombectomy and temporary arteriovenous fistula in combination with anticoagulant treatment upon all pregnant or recently pregnant women coming to our department with acute iliofemoral venous thrombosis from August 1985 to March 1987. In this period, eight pregnant women and one woman 12 days after cesarean section were admitted. This is an incidence of 0.83 per 1,000 deliveries. All of the women were evaluated with a mean follow-up time of 15 months. Six of nine patients were clinically asymptomatic. Six had a normal ambulatory strain gauge volumetry and seven, a normal occlusion strain gauge plethysmography. Two women delivered by cesarean section, one woman had an induced abortion because of the disease, two women delivered after partus provocatus and four delivered spontaneously. We conclude that thrombectomy and temporary arteriovenous fistula together with heparin is a safe treatment of acute iliofemoral venous thrombosis during pregnancy. There is no need to interrupt the pregnancies except for obstetric reasons.
