RESUMO
From November, 1980, to May 1985, 699 patients have undergone percutaneous transluminal coronary angioplasty of 784 lesions at our institutions. Simultaneous surgical standby was available on all cases. One hundred twenty-four patients (18%) underwent immediate myocardial revascularization; 45 (6%) were operated on because the lesion could not be dilated. Seventy-nine patients (11%) underwent immediate operation for an acute complication of angioplasty: coronary occlusion in 45, dissection in 29, coronary perforation in three, and atrial perforation in one. Fourteen patients (18%) required cardiopulmonary resuscitation en route to the operating room, and 10 patients (20%) had insertion of an intra-aortic balloon pump in the cardiac catheterization laboratory. The average time from complication to reperfusion was 87 minutes, ranging from 40 to 165 minutes. An average of 2.0 grafts per patient (ranging from one to five grafts per patient) were performed. Of those 79 patients who underwent operation for an acute complication, one died (1.3%), 31 patients (39%) had a myocardial infarction according to enzyme criteria (creatine kinase-myocardial band greater than 40 IU), and 17 patients (22%) had new Q waves on the electrocardiogram. Good results are related to minimizing the time the myocardium is ischemic. No patient in whom reperfusion was begun in less than 75 minutes had a Q wave infarction or a creatine kinase-myocardial band level greater than 40 IU. Simultaneous surgical standby is the only method allowing immediate access to surgical facilities. A standby team of eight persons and equipment were immediately available for emergency bypass grafting for an average of 3.6 hours (range 1.3 to 5.4 hours per angioplasty attempt). The patient charges for this simultaneous standby were $632.00 per angioplasty attempt, or $442,278.00 for the entire series. The actual cost of the standby was over $1,700.00 per attempt totaling $1,188,843.00 for the 699 patients. This underestimation of the cost of surgical standby has occurred in other series, because little mention has been made of this cost in the published reports on the cost effectiveness of angioplasty. In terms of time demands, over 2,500 hours were spent by surgeons standing by for the 699 attempts. Simultaneous surgical standby is the most effective means of limiting the time the myocardium is ischemic after an angioplasty complication. However, this method is costly, necessitating more of a financial and time commitment than generally anticipated. Future studies of the cost effectiveness of angioplasty should include the cost of surgical standby with accurate per-patient cost accountability.

To assess the safety and efficacy of concomitant pulmonary resection and cardiac operation requiring cardiopulmonary bypass, the records of 19 patients were reviewed. Eighteen patients (94.7%) presented with cardiac symptoms and were found to have pulmonary pathology of indeterminate etiology. Pulmonary resections were performed through a median sternotomy in all but 1 patient, who underwent posterolateral thoracotomy and right middle lobectomy after repositioning because dense adhesions prevented adequate dissection through the initial incision. A total of 24 resections were performed. Sixteen (66.7%) were performed on cardiopulmonary bypass. Six wedge resections (25.0%) were performed before bypass. Two lobectomies (8.3%) were performed after infusion of protamine sulfate. Nine patients (47.4%) had benign pathology, 7 (36.8%) had primary carcinoma, and 3 (15.8%) had metastatic disease. Bleeding complications occurred in 15.8% of patients (3/19). There was 1 perioperative death (5.3%), which was due to adult respiratory distress syndrome after intraoperative hemorrhage followed lobectomy for bullous disease. Another patient required lateral extension of the sternotomy during an episode of exsanguinating intraparenchymal pulmonary hemorrhage, which resulted in lobectomy, as well as costochondral and sternal osteomyelitis. A third patient required exploration for bleeding at the staple line. Postoperative complications occurred in 7 patients (36.8%) and were predominantly respiratory (5/7, 71.4%) (p = 0.006). The median postoperative hospitalization was 15 days. Although comparison of patients who underwent pulmonary resection during bypass with those who had resection either before heparinization or after protamine infusion showed no significant difference with respect to age, incidence of malignancy, operation performed, complications, postoperative hospitalization, or survival, this was probably due to the small number of patients in the study.(ABSTRACT TRUNCATED AT 250 WORDS)

Two hundred twenty-one consecutive adult cardiac surgical patients were examined prospectively for nutritional protein state, acute phase protein response, and delayed hypersensitivity reaction in an attempt to identify patients at high risk for the development of sternal wound infection, which occurred in 6 patients (2.7%). There was no significant correlation between preoperative nutritional protein concentrations (retinol-binding protein, prealbumin, and transferrin) and acute phase protein levels (C-reactive protein, alpha 1-acid glycoprotein, and complements B and C3), nor a statistically significant relationship between nutritional state or acute phase protein response and the development of sternal infection. Preoperative complement C3 levels were elevated, however, in 80.0% of those in whom sternal infections developed compared with 30.6% of those with well-healed wounds. Similarly, postoperative concentrations of alpha 1-acid glycoprotein were elevated in 80.0% of those in whom sternal infections developed compared with 28.6% of those with well-healed wounds. There was no correlation between delayed hypersensitivity and the risk of sternal infection, nor between preoperative nutritional protein and acute phase protein values. Seventy-three percent of patients were anergic on postoperative day 2. Stepwise logistic regression showed that age, body weight, preoperative intensive care unit stay, repeat median sternotomy, internal mammary artery grafting, postoperative hemorrhage, and postoperative cardiac arrest correlated with the development of sternal infection, whereas transfusion requirement, reexploration for bleeding, and the operation performed did not. We conclude that routine delayed hypersensitivity testing is of no value in predicting high-risk cardiac surgical patients when the anergy battery is placed on the preoperative day. Although statistically insignificant, possibly due to the small number of patients in whom sternal infection developed in this study (type II error), a larger study might find preoperative complement C3 and post-operative alpha 1-acid glycoprotein levels to be predictive of patients at risk for the development of sternal wound infection. The final logistic model for the predicted risk 2%) of sternal wound infection is: PREDSWC = exp(EQ)/1 + exp(EQ) where EQ = (0.38 x age) + (0.24 x weight) + (5.42 x preop ICU) + (4.39 x redo) + (7.14 x IMA) + (4.49 x hemorrhage) + (8.81 x arrest) - 62.72, and where preop ICU, redo, hemorrhage, and arrest are defined as yes (1) or no (0), IMA-is defined as 0, 1, or 2, age is in years, and weight is in kilograms.

One hundred thirty-six patients underwent thrombolytic therapy for acute evolving myocardial infarction from June, 1981, through December, 1982. Of these patients, 51 underwent coronary bypass procedures from two hours to 90 days (average, 16 days) following thrombolytic therapy. Six (12%) had single-vessel disease, 15 (29%) had double-vessel disease, and 30 (59%) had triple-vessel involvement. Ejection fraction values ranged from 21 to 60%. The average number of grafts performed per patient was 3.4. There were no operative deaths in this series. Postoperative hemorrhagic problems were minimal, and the incidences were no different from those for other coronary bypass patients. In follow-up ranging from 2 to 18 months, there was no recurrence of severe angina or other clinical evidence of saphenous graft occlusion in the thrombolysed vessels. Of the 45 patients eligible to return to work, 40 (89%) have done so. The data from this series suggest that surgical myocardial revascularization after intracoronary thrombolytic infusion for acute myocardial infarction can be performed safely and that complete recovery and a high return-to-work ratio can be anticipated.

Autotransfusion was used in 38 patients with ruptured ectopic pregnancy. There was no mortality in this series. Transfusion-related morbidity occurred in six patients; two developed clinical coagulopathy; two, pulmonary edema; and two had minor transfusion reactions to concomitantly used banked blood. The procedure is safe and efficient and represents less risk to the patient than does the use of banked blood. The savings of the large amount of banked blood is certainly in keeping with a more salutary use of this valuable resource.

A case of sweat gland carcinoma arising from the right fifth finger which later metastasized to the regional lymph nodes and the lungs is the subject of this report which attempts to establish further the true characteristics of this definite pathological entity. The diagnosis of sweat gland carcinoma has been loosely applied to a variety of lesions, and it was not until recently that more exact and appropriate criteria were used to establish the diagnosis of sweat gland carcinoma. The case reported in this manuscript possesses most if not all the criteria necessary to make a diagnosis of sweat gland carcinoma. Further review of the literature shows that this is a rare and aggressive neoplasm as this case illustrates. Radical surgery of the primary lesions with radical regional lymph node dissection whenever possible is recommended for the initial treatment, and combination chemotherapy and radiotherapy may be employed in the palliative treatment of the more advanced forms of the disease.
