[Myocardial ischemia and carotid surgery. Holter study of 21 severe coronary patients. Preventive effect of intravenous trinitrin].

Cervical carotid artery surgery is increasingly being performed in elderly, polyvascular, high risk patients, some of whom have severe coronary artery disease. Is this right? The effects of this almost routine surgical procedure from the technical point of view were analysed with respect to the coronary lesions. 1. A retrospective study of coronary events occurring in the peroperative or immediate postoperative period and at short term was carried out in 367 patients aged over 70 years old (average 73,4 years) undergoing 424 cervical carotid artery procedures with a particularly high coronary risk. 2. A prospective study of ischemic ECG changes occurring in the period between induction of anaesthesia and the 4th postoperative day was performed by Holter monitoring in 21 patients with severe coronary artery disease. The mortality and morbidity observed were very low and could be further reduced by certain anaesthetic and pre-and postoperative techniques. In particular, prophylactic intravenous trinitrin (0,5 to 1,5 gamma kg/min) was most effective in protecting the myocardium in 15 patients with severe angina (classes III and IV of the NYHA classification). The authors conclude that the surgical result depends mainly on the neurological status of the patients, the best results being obtained in asymptomatic patients (stage 0) or those having suffered transient ischemic attacks (stage 1). The global mortality and morbidity rate was less than 2 p. 100 in those groups. On the other hand, long-term survival depends mainly on the severity of the coronary artery disease.

[Aneurism in a persisting sciatic artery. One case (author's transl)].

The authors report on the first case of aneurism in a persisting sciatic artery observed in France. The condition was complicated by truncular embolism and fissuration and was successfully treated by endo-aneurismorrhaphy. Restoration of arterial continuity is nevertheless necessary in most cases of aneurysm affecting a complete persistant sciatic artery (providing the vascular supply for the whole lower limb) which represents the commonest anatomical type.

[Severe ischemic accidents from ergotism. A report on 3 cases. Value of a new antidote : sodium nitropruside (author's transl)].

The autors describe 3 recent cases of severe ischemic accidents from ergotism affecting different regions. Two of the cases resulted from taking Gynergene (ergotamine tartrate) for a short period, while the other case followed continuous administration of Desernil (Methysergide) for 3 years. The third case was treated at a late stage by continuous peridural anesthesia and various vasodilators without success and led to very severe mutilations in two young women. The third case was treated by continuous infusions of sodium nitropruside (SNP) under hemodynamic control, and recovery was rapid and complete. The value of SNP as an antidote for severe ergotism is discussed, together with its mode of administration, and precautions necessary when prescribing this extremely powerful vasodilator treatment for this indication.

[Surgical treatment of chemodectomas of the neck (author's transl)].

About 16 cases of chemodectomas of the neck, with surgical management during the five past years, the authors present an actualisation about surgery of these tumors of the paraganglionnary system at the level of the neck. After recording the different means of the diagnosis, particulary carotid arteriography, they insist about the necessity of a complete excision of these tumors because of local risks due to the neurovascular compression and infiltration, and because of general risks due to malignant metastasis. Three major risks run with surgery in these cases: hemorrhagic, neurologic, and vascular risks (because of the possible extension to the carotidian axis). 14 total excisions and 1 incomplete excision were performed; 1 no-operated tumor was noted because of the death of the patient before surgery due to a metastatis paraplegia. 4 resections of the carotidian axis with 1 repair by end to end anastomosis and 3 by a vein graft were necessary. No mortality after surgery in these patients was encountered. No recurence, no metastatic phenomen in our patients after the total excision of the primary chemodectoma of the neck even for one histologically maligant tumor, three years ago.

[Splenic trauma complicating translumbar aortography : a report on 2 cases (author's transl)].

Two very rare cases of splenic trauma following high translumbar aortography are described. Two types of clinical picture are observed : severe intraperitoneal hemorrhage, subcapsular and then intraperitoneal, from rupture of the spleen, and septic peritonitis following rupture of an intra- and perisplenic abscess. The authors review the frequency, mechanism, and prevention of complications following translumbar aortic puncture.

[Treatment by a direct surgical approach of a false arterio-venous traumatic aneurysm between the vertebral artery and the internal jugular vein at the level of the atlas (author's transl)].

The authors report a case of traumatic arteriovenous fistula between the vertebral artery and the internal jugular vein at the level of the atlas, treated successfully by a direct surgical approach which permitted exclusion after simple dissection. The relative ease of the surgical approach of the suboccipital segment of the vertebral artery may permit one to extend this technique to other more common indications, in particular due to atheroma.
