[Anatomic-clinical presentation. Testicular teratocarcinoma with thoracic-abdominal adenopathy].

This case report of a young man with a testicular germ cell-teratoma tumor illustrates the necessity of a multidisciplinary sequential approach to ensure chance of cure. The outcome of patients with advanced germ cell tumor depends on the optimal clinical management. Residual masses are frequent, and their histology can be different than the initial one (i.e., only residual mature teratoma cells or necrosis-fibrosis). Therefore a second surgery on residual masses with curative intent, may be important to optimalize the treatment and follow up.

Carotid chemodectomas. Experience with nine cases with reference to preoperative embolization and malignancy.

The medical records of nine patients (five female and four male, mean age 58 +/- 5 years) presenting with a carotid chemodectoma between 1983 and 1995 were reviewed. In two cases (22%) the diagnostic was not suspected at the time of initial presentation. The most common complaint was a swelling in the anterolateral region of the neck. One patient (11%) presented with a preoperative peripheral nerves deficits (vagus and hypoglossal palsies and Horner's syndrome). Two tumours were embolized preoperatively with polyvinyl alcohol particles. Complete surgical excision was possible in each patient and the plane of resection was adventitial. In three cases, early ligation of the external carotid artery facilitated the resection. In two patients, the vagus nerve was sacrificed because of tumour involvement. No operative mortality was observed and no vascular complication occurred. In addition to the patient with preoperative neurologic symptoms, three patients developed peripheral nerve deficits (vagus and hypoglossal nerves) postoperatively. Two of these deficits were transient. These peripheral neurologic complications were observed with the largest tumour sizes. Two cases were malignant (lymph nodes and bony metastases). These two patients received postoperative radiotherapy. The mean follow-up period 63 +/- 19 months. No patient developed local recurrence during the follow-up. Two patients died during the follow-up, one for condition unrelated to their disease and the second from metastatic dissemination. In conclusion, carotid chemodectomas may be safely resected. The best way to minimize the rate of complications is to operate them at an early stage of evolution.

Right aortic arch with aberrant left subclavian artery. Report of two cases.

Two cases of adult asymptomatic right aortic arch with an aberrant subclavian artery are reported. They were discovered at time of coronary surgery. Preoperative coronary arteriography failed to demonstrate the anomalies. In one case, the right arch was suspected on chest x-ray and preoperative barium oesophagography. In one case, the proximal suture of one saphenous bypass graft was performed on the left common carotid artery. Right aortic arch is a malformation rarely discovered in adults. It generally produces no symptoms when not associated with cardiac disease.

Determination of the expansion rate and incidence of rupture of abdominal aortic aneurysms.

Expansion rate and incidence of rupture of abdominal aortic aneurysms in relation to their size is a source of debate. We studied 114 patients (out of a cohort of 752 consecutive patients admitted with abdominal aortic aneurysms) who were denied any immediate operation because of patient's refusal, high surgical risk, or small transverse diameter as assessed by CT scanning and ultrasonography. All patients not operated on underwent from two to six repeated examinations during an average follow-up period of 26.8 months (range, 3 to 132). Forty-seven patients (41.2%) were subsequently operated on electively because of marked increase of transverse diameter of the aneurysm (n = 44) or for other reasons (n = 3), with a death rate of 0%. Eighteen other patients underwent emergency operation for leaking or ruptured aneurysms, and there were five deaths. The incidence of rupture was clearly related to the final diameter value, rising from 0% in aneurysms less than 40 mm to 22% in large size aneurysms (greater than or equal to 50 mm). Among the 49 patients not operated on, one died of rupture before operation and five of causes unrelated to the disease. Using individual serial measurements, we determined the linear expansion rate of the aneurysm, which proved to be related to initial diameter values: 5.3 mm/year for diameters less than 40 mm (n = 49), 6.9 mm/year in the 40 to 49 mm group (n = 41), and 7.4 mm/year for diameters of 50 mm or more (n = 24).(ABSTRACT TRUNCATED AT 250 WORDS)
