[Myocardial infarction in pregnancy].

Myocardial infarction during pregnancy and puerperium is very rare. Increased awareness of its possible occurrence is important for diagnosis. We report on a 37-year-old woman without coronary risk factors who suffered an anterior septal infarction in the last trimester. Coronary angiography one month after normal delivery and two months after infarction revealed normal coronary arteries. Ventriculography showed anteroseptal akinesia. The assumed etiology of myocardial infarction appears to be coronary spasm. A history of vasospasm in other vascular beds, migraine and Raynaud's phenomenon support this hypothesis. The literature is reviewed with special emphasis on clinical picture, prognosis, etiology and management of myocardial infarction during pregnancy.

[Microsurgery of the fallopian tube].

The goal of infertility surgery is to restore anatomic relationship to as close to normal as possible maximizing the chances for conception and intrauterine pregnancy. The outcome has been markedly, improved by the advent of microsurgical techniques. More than 10 years of microsurgical experience have enabled us to clearly define situations where infertility surgery is especially successful. In refertilization after tubal sterilization, the results with microsurgery are unsurpassed. In proximal, but also distal, postinfectious tubal disease, intrauterine pregnancy rates are clearly better than those achieved with in vitro fertilization or other techniques.

Modern synthetic suture materials and abdominal wound closure techniques in gynaecological surgery.

The introduction of modern synthetic suture materials and an individualized approach to wound closure techniques in gynaecological surgery has created new options. Although many issues remain open to question, we have no doubt that catgut and chromic catgut can be declared obsolete in gynaecological surgery. The choice of synthetic suture materials has to be made on personal preferences and clinical experience. If the use of non-absorbable sutures is desired, with few exceptions monofilament suture material is clearly the first choice. Abdominal opening and closure techniques and the selection of appropriate suture materials have to be considered as important factors in minimizing wound healing complications. The decision-making process is based on the knowledge of anatomy, wound healing and possible risk factors. From theoretical considerations, mass closure of all layers apart from skin is considered to be the superior concept. The incidence of incisional hernias and sinus formation will depend on proper technique and possibly the choice of suture material. Some suggestions to individualize opening and closure of the abdomen are made although prospective randomized trials in gynaecology have not yet been performed.

Dihydroergotamine and heparin or heparin alone for the prevention of postoperative thromboembolism in gynecology.

The efficacy of combined dihydroergotamine and heparin (DHE-heparin) medication (2500 IU sodium heparin and 0.5 mg DHE, both given subcutaneously twice daily) or low doses of heparin (5,000 IU of sodium heparin given subcutaneously thrice daily) in preventing postoperative thromboembolic complications was investigated in a prospective, randomized trial in 125 patients over the age of 40 years undergoing elective major gynecological surgery. The I125-fibrinogen uptake test was used for the diagnosis of deep vein thrombosis. There was no statistically significant difference in the incidence of thromboembolism between the groups. Major bleeding occurred less often (p < 0.05) in the DHE-heparin group.

Prevention of postoperative thromboembolism by dextran 70 or low-dose heparin.

The efficacy of intravenous infusion of dextran 70 or subcutaneous administration of low-dose heparin in preventing postoperative thromboembolic complications has been investigated in a prospective randomized trial. During part 1 of the study, 232 patients over the age of 40 years who were undergoing major gynecologic surgery underwent a complete test protocol. The 125I fibrinogen uptake test (FUT) was used for the diagnosis of deep vein thrombosis (DVT) in 117 patients in the dextran and 115 patients in the heparin group. Heparin was significantly more effective than dextran for reducing DVT (P less than .001). During part 2 of the study no FUT was done but the incidence of clinical and fatal pulmonary embolism (PE) and the number of complications were studied. Of 444 patients (parts 1 and 2) 1 fatal and 2 nonfatal pulmonary emboli were diagnosed. All the emboli occurred in the dextran group. The benefit: hazard ratio appeared to favor heparin for the prophylaxis of DVT.
