Postoperative investigation of left ventricular aneurysm resection.

We reviewed 35 patients undergoing resection of a chronic postinfarction left ventricular aneurysm. There was 5.7% operative mortality. Of the long-term survivors, 80% are functional class I or II. Ten patients had postoperative left ventriculograms studied by means of a computerized analysis of endocardial motion using internal orthogonal and radial grids. Postoperative end-diastolic volumes were much greater than normal and large akinetic areas were present although there was good improvement in the patient's functional capacity. Grid analysis of endocardial motion correlated better with the patient's postoperative clinical status than did measurements of end-diastolic pressure and volume, ejection fraction, or visual inspection of the postoperative left ventriculogram.

Massive pulmonary embolism permitting paradoxical systemic arterial embolism: successful surgical management.

The case of a young woman, receiving oral contraceptives, who developed massive pulmonary embolism producing circulatory collapse and paradoxical arterial embolism through a patent foramen ovale is documented.. Limb viability was threatened. Emergency management included removal of arterial and pulmonary emboli, surgical closure of the patent foramen ovale, inferior caval partitioning, ovarian vein ligation, and short-term anticoagulation. Recovery was rapid and complete.

The indications for pericardiectomy in the uremic pericardial effusion.

Uremic pericarditis developed in 37 of 295 patients (8 percent) admitted to the chronic hemodialysis program at our institution. Sixteen patients (43%) underwent limited pericardiectomy through a left anterior thoracotomy approach with no operative deaths and minimal morbidity (19%). Twenty-one patients (57%) were treated successfully with intensive hemodialysis. The use of pericardiocentesis did not avert cardiac tamponade in any patient in our series. The procedure was associated with two life-threatening complications and its use, therefore, has been limited in the therapy of uremic pericarditis. We recommend surgical intervention in all patients with hemodynamic instability and echocardiographic evidence of enlarging effusions or an effusion unchanged in size following 10 days of intensive hemodialysis.

Peripheral intravenous infiltration necrosis.

Peripheral extravasation of intravenous solutions containing calcium salts and/or 10% dextrose has caused significant local tissue necrosis in 8 patients, including 6 infants. These incidents prolonged hospitalization and in 5 cases caused severe disfigurement or imperiled limb function. Treatment followed established principles of debridement, early skin grafting and secondary reconstruction as needed. While intravenous alimentation or the administration of calcium salts if often indicated by the clinical situation, the physician administering these drugs must realize that extravasation may cause serious sequelae.

Exposure through a coronal incision for initial treatment of facial fractures.

The coronal incision approach to Le Fort III fractures gives excellent exposure for anatomical reduction and internal fixation of the fracture sites. Either an extracranial, or a combined intracranial procedure, is feasible. The exposure obtained not only facilitates the reduction and the fixation but, with the addition of transconjunctival incisions, the patient benefits by not having multiple surgical scars in the face.

Reconstruction of cranial defects.

We have found that small defects, particularly those within the hairline, are easily reconstructed with methy methacrylate prepared at the operating table. Larger defects, especially in children and active adults, are benefited by autogenous bone grafts and we prefer split rib. When the fabrication facilities are available the preformed silicone implants offer much to the surgeon. They may be sculptured to correct difficult contour problems such as in the supraorbital or forehead region and are especially useful to fill in defects where the bone is present, but depressed. These three methods have many advantages over the metallic implants. There is little complaint of the implant being cold when the patient is exposed to cold weather and a very important fact is that these methods not only provide a radiolucent reconstruction, but also do not affect EEG examination.
