[Risk surgery of the carotid. A balanced assessment of the use of locoregional anesthesia].

The authors report their experience with regional anaesthesia in carotid surgery. They performed 80 carotid endarterectomies in 79 patients. Thirty-three patients were at high surgical risk because of contralateral internal carotid artery occlusion or bilateral stenosis (greater than 70%) or ischemic brain areas for past stroke. In this high risk group 4 strokes were registered in the postoperative period, while no strokes appeared in patients non at risk.

[Funnel chest and pigeon chest today].

The authors report on the results of sternochondroplasty according to Ravitch in a group of 31 patients with funnellike or carinated chest. The results appear to be conditioned to the type of anomaly, to the kind of surgery performed, to the age at which the patients undergo surgery. From a functional viewpoint results appear to be markedly better in pectus carinatum as compared to those in pectus excavatum. The latter anomaly requires a prolonged traction of the anterior thoracic "volet": this excludes any possibility of using external traction techniques (poor results in 25-30% of cases). The high percentage of fair results with reference to marring scars or partial excavations of the thoracic wall has lead us to operate (with reference to some ages: less than 5 years old; 9-14 years old) on these patients after they have reached age 15. The authors hope that a larger number of patients will be treated conservatively (in cases of carinated chest) or else that they undergo minor plastic surgery (in funnel chest cases).

Recurrence of autonomous hyperparathyroidism in calcium nephrolithiasis.

In a woman with bilateral recurrent calcium nephrolithiasis and hypercalciuria, hypercalcemia developed and she underwent parathyroid surgery, which led to excision of a histologically-confirmed adenoma. The patient became normocalcemic but remained hypercalciuric despite reduction of dietary calcium intake. Several calculi recurred in both kidneys. Four to six years after parathyroidectomy, hypercalcemia recurred and the patient underwent a new surgical exploration; a parathyroid gland with diffuse adenomatous aspects and another gland with pure hyperplasia were excised. Once again, after surgery the patient became normocalcemic but remained hypercalciuric. Evidence for a "renal calcium leak" hypercalciuria was obtained, and thiazide administration led to normalization of urinary calcium excretion. In calcium nephrolithiasis, persistent hypercalciuria may lead to recurrence of autonomous hyperparathyroidism.

Postoperative chylothorax. Six cases in 2,500 operations, with a survey of the world literature.

We have systematically reviewed the literature concerning iatrogenic chylothorax and shall report our personal observations on the subject. Despite an increasing number of thoracic operations, injuries to the thoracic duct are infrequent. Cardiovascular and esophageal procedures are the most frequent causes of chylothorax. Malformations of the thoracic duct and other organs of the mediastinum have often been involved in lymphatic injury. Consequently, we believe that a complicating chylothorax may result from varied causes rather than solely from a surgical error.
