Late sequelae of penetrating cardiac injuries.

Fifty-four patients who survived a penetrating cardiac injury were assessed for late cardiac complications. The mean follow-up after injury was 23 months. Clinical history and physical examination suggested cardiac complications in nine patients (17 per cent). Electrocardiogram was abnormal, but usually not diagnostic, in 17 (31 per cent). Routine two dimensional Doppler echocardiography revealed abnormalities in 17 (31 per cent). Ten patients (19 per cent) had valvular or septal defects. Other abnormalities included pericardial effusion, ventricular and septal dysfunction, and ventricular dilatation. Although it is impossible to determine how many of these abnormalities were post-traumatic, it seems that the incidence of late sequelae of cardiac injuries is high, and it is recommended that routine late follow-up of these patients should be done. Assessment should include routine echocardiograms.

Are carotid body tumours malignant?

Carotid body tumours (CBTs) are slow-growing, malignant neoplasms by virtue of their local spread by continuity and contiguity and metastatic spread by lymph and blood. This article reports the findings of a pathological study of the growth characteristics of CBTs.

Giant lateral neck swellings.

Four patients with extremely large lateral neck swellings are described. In the discussion the controversy about using radiotherapy: (i) to make an 'inoperable tumour operable', and (ii) to 'sterilise the operative field' is considered. It is concluded that modern radiotherapeutic techniques probably satisfy these requirements.

Multiple malignant paragangliomas. A case report.

The extra-adrenal paraganglia may be divided into branchiomeric (parasympathetic) and paraxial or para-aortic (sympathetic) networks. A patient is described with two synchronous branchiomeric paragangliomas--a carotid body tumour (glossopharyngeal) and a cardiac chemodectoma (vagus). Both tumours were locally invasive and therefore, by definition, malignant.

Carotid body tumours. A review of 52 cases.

During a 22-year period (1962-1984) 52 carotid body tumours were encountered in 50 patients. In addition, 2 of the patients had tumours of the glomus intravagale. One patient had a recurrent tumour, the first one having been removed 23 years previously. The ages ranged from 23 to 80 years, the female/male ratio was 2:1, and the right side was affected twice as often as the left. Four patients were treated non-surgically; 3 were too elderly and frail to undergo the operation and in the 4th case the tumour was considered inoperable. In 2 cases excision was attempted but abandoned for technical reasons. In the remaining 44 patients 46 tumours were excised, with grafting of the internal carotid artery in 6 cases. There were 2 deaths (4.5%), 1 after hemiplegia and 1 a pulmonary embolus. Eight patients were left with cranial nerve palsy, which had been present preoperatively in 5 cases. Of the tumours 7 (13.5%) were found to be malignant. The results of endocrine studies when undertaken were normal. Although ultrasonography and computed tomography were used in some cases, arteriography was the definitive mode of investigation.

Isolated granulomatous pancreatitis.

Only five patients with clinically apparent noncaseating granulomatous pancreatitis have been recorded, so far as we can tell. We describe a patient with noncaseating granulomas confined to the pancreas who developed obstructive jaundice and acute abdominal pain.

Carotid body tumors.

A review of carotid body tumors is presented together with a personal series of 16 patients managed in 4 years. Angiography was diagnostic in all instances. Five patients showed evidence of local invasion, while no patient had distant spread. Early recognition and surgical management were effective in the treatment of all operable tumors. Local removal of group 1 tumors without shunting is safe, with no morbidity or mortality in this series. The use of an indwelling shunt in group 2 tumors is recommended because of the risk of vessel wall damage during dissection and because reduction in blood supply to these large tumors facilitates their removal. We also recommend the use of an indwelling shunt in group 3 tumors when an en bloc resection of the vessels and tumor is performed in order to maintain cerebral perfusion.
