This study analyses retrospectively 100 consecutive thoracotomies performed for lung cancer before end 1986. Chest CT scan assessed mediastinal lymph node disease, chest wall invasion and mediastinal invasion, with an overall accuracy of 75, 93 and 91 per cent respectively; mediastinal lymph node disease was significantly more underestimated in the stage III group. Characteristics, type of surgical and adjuvant therapy and follow-up were analysed in the T3 (16 patients) and the N2 (18 patients) group. Complete resection was possible in only a minority of the cases: 3 in the T3 group and one in the N2 group. Of the T3 group, 3 patients have survived more than 3 years and 3 are actually still alive. Of the N2 group, only 2 patients are still alive. Most deaths were due to generalization of the disease.

Diagnosis of arterial occlusive disease of the lower extremities by laser Doppler flowmetry.

Laser Doppler Flowmetry offers the possibility of non-invasive and continuous recording of tissue blood flow. Skin blood flux in resting state and during postocclusive reactive hyperemia was measured at the pulpa of the toe in 21 normal lower limbs and in 58 limbs with arterial occlusive disease. Proper assessment of postischemic flux- and time- parameters (beginning of reactive hyperemia, peak flux, time of peak flux and duration of hyperemic flux) permits accurate separation of healthy and diseased limbs.

Posttraumatic rupture of the thoracic aorta.

Ten patients with traumatic lesions of the thoracic aorta were seen in a hospital. Most were victims of traffic accidents and presented severe associated lesions along with their vascular trauma. We found that the vascular injuries were clinically manifest in only a minority of patients. The remaining ruptures were discovered through CT-scanning of the mediastinum or angiography. We believe that in every major trauma victim aortic lesions should be actively sought for by complimentary examinations to guarantee maximum survival of the patients.

Recurrent pulmonary embolism: importance, diagnosis, management and prevention.

Pulmonary emboli, even small, cause irreparable lung damage. Recurrent pulmonary emboli further increase the amount of non functional lung tissue and may result in incapacitating respiratory disease or death. It is therefore mandatory that the disease be correctly diagnosed and adequately treated. As prevention is better than cure, every patient presenting with clinical signs of deep venous thrombosis (DVT) should be correctly explored. The site and size of thrombosis must be visualized preferably with contrast venography with imaging of the veins of the limbs, iliac veins and vena cava. Risk factors such as obesity, immobilization etc. must be taken into account. Underlying disease such as heart disease and venous insufficiency must be treated. Malignancy must be looked for as in a recent series of patients with primary DVT which were studied, 15% presented with an up till then unknown malignant disease. In patients presenting with recurrent DVT this percentage rose to 20%. When a patient presents with DVT of the femoro-iliac vena cava axis, aggressive treatment must be adopted. Fibrinolysis or if this is contra-indicated, thrombectomy will be used. A vena cava filter may be necessary and longterm anticoagulation is mandatory. The same rationale is applicable in cases of pulmonary embolus whether it is a primary event or a recurrence.

Transaxillary thoracotomy for treatment of spontaneous pneumothorax.

This study reports the retrospective analysis of operative treatment of 20 cases of spontaneous pneumothorax during the last 4 years. Surgical indications included recurrence, recollapse of the lung on clamping the chest tube, nonexpansion of the lung despite adequate drainage or persistent air leak, and giant bulla. A transaxillary thoracotomy was used in all cases to treat sites of air leak and subpleural blebs by resection (14 cases) or oversutering (4 cases) combined with pleural abrasion (19 cases) or apical pleurectomy (1 case). This approach has met with excellent results without major morbidity or mortality.

Fibromuscular dysplasia of the internal carotid artery.

An observation on symptomatic fibromuscular dysplasia of the internal carotid artery, surgically treated by graduated internal dilatation is presented. Fibromuscular dysplasia is a segmental, nonatheromatous disease of small to medium-sized arteries, affecting mainly renal arteries. Involvement of the internal carotid artery is often an incidental angiographic finding in asymptomatic patients, but can be associated with specific neurologic symptoms requiring surgical treatment. The histopathologic character, the pathogenesis, the clinical manifestation, the diagnosis and the therapeutic possibilities of this affection are discussed.

Femorofemoral bypass grafting in high-risk patients.

A total of 37 extra-anatomic femorofemoral bypasses were inserted for severe unilateral iliac artery stenosis or a thrombosed graft limb of an aorto-bifemoral bifurcation graft. All patients were severely debilitated and at high risk for direct aorto-iliac reconstruction. 30% suffered severe claudication; 70% had ischemic restpain or trophic lesions. 43% died during a mean follow-up period of 17 months. This study demonstrates that the extra-anatomic femoro-femoral bypass procedure is an effective alternative therapeutic modality for high-risk patients with an acceptable operative mortality (5.4%) and morbidity to improve the quality of life.

[Systematic research on an etiology in apparently primary deep venous thrombosis. Apropos of 59 cases].

Primary deep vein thrombosis was confirmed by phlebography in 59 cases between Jan. 1981 and Jan. 1984 in the department of Cardiovascular Surgery of the Academic Hospital of the V.U.B. Brussels. Investigations conducted in all patients included blood and urine analyses, chest radiography, electrocardiogram, gynecologic or urologic examinations and abdominal and pelvic ultrasound imaging. Findings demonstrated one or more risk factors in 92% of cases, the principal ones being obesity, a history of thromboemboli and, in women, the use of oral contraceptives. Nine patients had cancer and 4 of these received combined surgery-chemotherapy. All cases of so-called primary deep vein thrombosis should be investigated routinely for risk factors, because of the need and possibilities for treatment in some of them, particularly since procedures are non-invasive, of low cost, and easily performed during initial heparin therapy.
