Detection of covert myocardial sarcoidosis by scalene node biopsy.

The antemortem diagnosis of myocardial sarcoidosis is rare in patients without overt signs of the disease. Two patients are presented to alert physicians to the value of early scalene node biopsy when sarcoidosis could be the cause of marked disturbances in cardiac conduction. The first patient, aged 29 years, had first, second, and third degree atrioventricular block and intermittent left and right bundle-branch block; the second, aged 59 years, had second degree atrioventricular block and complete right bundle-branch block. Both had diagnoses of sarcoidosis based on scalene node biopsy. The cardiac conductive disturbance improved, and the symptoms disappeared with steroid therapy.

The coin lesion story: update 1976. Twenty years' experience with thoracotomy for 179 suspected malignant coin lesions.

We reviewed 179 patients who had undergone thoracotomy and resection of a suspected malignant coin lesion of the lung over the past 20 years to see if a policy of early thoracotomy was therapeutically valid. The average diameter of all lesions was 1.6 cm; the average diameter of 27 malignant lesions (15 percent) was 1.8 cm. Follow-up of the 27 patients with malignant neoplasms was 100 percent. The present survival rate of the 19 patients with primary lung cancer is 89 percent (17/19). Of 12 cases of primary lung cancer followed for five years, ten (83 percent) survived. The five-year survival of the eight patients with metastatic lesions was 25 percent (2/8). There were no postoperative deaths and few serious postoperative complications (four patients or 2 percent). Very small primary lung cancers detected and treated early do have the same poor prognosis as larger primary cancers.

Effective surgical palliation of giant compressive bullous emphysema (vanishing lung syndrome): long-term follow-up.

Giant compressive bullous emphysema is rare. The three major considerations for operation involve a breathless patient with giant bullae occupying more than one-third of one lung field who has a positive pulmonary arteriogram revealing diminished blood flow to the involved lung. Finally, we think that the survivors in our series, eight long-term postoperative patients alive one year to 14 years, supply gratifying evidence that surgery can provide effective and safe palliation.

Prognostic value of electroencephalography in cardiac surgery.

One hundred seventeen patients undergoing cardiac operations over a two-year period were studied. Electroencephalograms were recorded preoperatively, in the recovery room (up to 12 hours following operation), 24 hours later, and further as required. Operative and anesthesia data were correlated with EEG findings. All patients had normal EEGs preoperatively. This unusual occurrence may largely reflect the absence of congenital heart disease and the small number of valvular lesions in our patients. Prognosis was not significantly influenced by age. Bypass time appeared directly related to outcome by group but not individually. Hypotension prior to pumping occurred most often and mean blood loss was greatest in the patients who had abnormal EEGs in the recovery room with progressively worsening patterns until death. In the recovery room many patients were awake, while others were either drowsy, lethargic, or asleep. Some were comatose. The level of consciousness was not as prognostic as was the EEG. The pattern of EEGs in the first few postoperative days is more important than any single record by itself. All those who showed progressive deterioration in the first two or three days died shortly thereafter.

Distal propulsion of vena cava umbrella by cardiac massage.

Distal propulsion of a 28 mm umbrella filter from vena cava to femoral vein occurred in a 75-year-old woman during external cardiac massage. After cardiac massage, filter position must be checked roentgenographically. Optimal management of distal migration might include placement of a second umbrella to prevent recurrent emboli and proximal migration of the dislodged umbrella.
