Use of Off-pump Coronary Artery Bypass Surgery Among Patients with Malignant Disease

Right hepatectomy under cardiopulmonary bypass for hepatocellular carcinoma with inferior vena cava tumor thrombus: a case report

BACKGROUND

The prognosis of hepatocellular carcinoma (HCC) with vascular invasion is extremely poor, especially in patients with tumor thrombus (TT) of the inferior vena cava (IVC), which is an oncological emergency with a high risk of sudden death due to TT extension or migration. Herein, we describe a case of HCC with TT of the IVC that rapidly extended into the right atrium (RA), in which right hepatectomy was performed under cardiopulmonary bypass.

CASE PRESENTATION

A 64-year-old man was diagnosed with HCC with IVC TT, and right hepatic lobectomy was scheduled. While awaiting surgery, he complained of respiratory distress and rushed to the emergency room. The TT had reached the RA, and the patient was in a state of oncologic emergency. We requested the cooperation of the cardiovascular surgery department, and under artificial cardiopulmonary support, the right atrium was incised, and a part of the TT was removed. The IVC was clamped to prevent tumor dispersal, and right hepatic lobectomy was performed. The remaining thrombus was excised along with the right lobe of the liver by incising the IVC. There were no serious postoperative complications, and the patient is alive 1 year and 5 months postoperatively.

CONCLUSION

Hepatic resection with cardiopulmonary bypass could be an option for HCC with TT reaching the RA.

Surgical treatment of lung cancer in patients with coronary artery surgery

The objective was to improve the surgical treatment tactics in patients with non-small cell lung cancer (NSCLC) and coronary heart disease (CHD), requiring myocardial revascularization.

Methods and materials. Two groups consisting of 24 patients operated on for NSCLC were examined. In one group, operations for NSCLC were performed in the second stage after coronary artery bypass grafting (CABG). Survival rates in both groups and factors influencing them were evaluated.

Results. The number of postoperative complications in both groups was comparable: 20.8 % in patients with CABG and 16.6 % in the group operated only for NSCLC. Indicators of relapse-free and overall survival did not differ significantly from each other (p=0.90 and p=0.95). Only the stage of the disease (p=0.009) and the implementation of complex cancer treatment in case of its necessity (p=0.035) had a reliably impact on the long-term results of the operation. The first stage of myocardial revascularization surgery did not affect the results of treatment (p=0.94), as well as the age of patients, the volume of performed surgery, the morphological picture of the tumor.

Conclusion. The staging approach to the treatment of patients with NSCLC and critical forms of CHD requiring myocardial revascularization is reliable, convenient and does not affect the long-term results of treatment.

Perioperative safety of simultaneous off-pump coronary artery bypass grafting with non-cardiac surgery of moderate-to-severe severity

BACKGROUND

To evaluate the perioperative safety of simultaneous off-pump coronary artery bypass grafting (OPCABG) with non-cardiac surgery.

METHODS

From September 2013 to January 2019, patients who underwent OPCABG surgery in the Department of Cardiology, Peking University First Hospital were included in this retrospective study. A total of 54 patients who underwent simultaneous surgery were defined as simultaneous surgery group. A total of 108 patients who had recently undergone isolated OPCABG surgery, and had similar vascular reconstruction methods were selected for matching, and these patients were defined as the OPCABG group. The general data and laboratory indicators were detected and were used as baseline data, and the EuroSCORE II scoring system was used to evaluate the surgical risk of patients based on these data. During surgery, intraoperative indicators were assessed and evaluated during surgery. In addition, evaluation of postoperative indicators was performed, including mechanical ventilation time, residence time in ICU, and proportion of perioperative myocardial infarction, perioperative stroke, postoperative renal failure, and surgical wound infection.

RESULTS

All the combined non-cardiac surgeries were assessed to be of moderate-to-severe grade by operative severity scoring system. The analysis of intraoperative indicators showed that there were no significant differences in proportion of emergency or urgent surgery, cases of arterial and venous anastomosis, and proportion of intraoperative blood transfusion between two groups (P > 0.05). Meanwhile, the values of operation time and intraoperative blood loss of patients in simultaneous surgery group were significantly higher than that in OPCABG group (P < 0.05). No perioperative death events occurred in this study. In terms of postoperative indicators, the values of operation duration and intraoperative blood loss of patients in simultaneous surgery group were significantly higher than that in OPCABG group (P < 0.05).

CONCLUSIONS

Simultaneous OPCABG surgery with non-cardiac surgeries of moderate-to-severe severity may not be associated with increased postoperative risks when compared with isolated OPCABG.

Early and Late Survival of On-Pump Cardiac Surgery Patients Formerly Affected by Lymphoma

BACKGROUND

Survival after cardiac surgery of patients formerly affected by lymphoma has not been well defined.

METHODS

Forty-five consecutive patients having prior Hodgkin's (HL patients, n=26) or non-Hodgkin's lymphoma (non-HL patients, n=19) underwent on-pump cardiac surgery at the authors' institution (2001-2016). Ischaemic, valvular, and ischaemic plus valvular heart disease were present in 14, 13, and 18 patients, respectively. Concomitant aortic disease was treated in three cases. The expected operative risk was calculated by the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II. The 10-year survival was estimated by the Kaplan-Meier method and the Charlson Comorbidity Index (CCI). The Cox proportional-hazards regression was used to evaluate the effect of some risk factors on survival.

RESULTS

With respect to non-HL patients, HL patients were younger (mean age, 52.5 vs. 64.7 years, p=0.0017) and underwent cardiac surgery later after lymphoma occurrence (median gap, 21.5 vs. 9.6 years, p=0.0079). No other intergroup differences as baseline characteristics, risk profiles (median EuroSCORE II, 2.3% vs. 3%, p=0.78), and in-hospital mortality (7.7% vs. 10.5%, p=0.99) were found. Older age, severe left ventricular dysfunction, and HL history were predictors of cardiac or cerebrovascular death (p<0.1). The 10-year, crude (40.4%) and adjusted (39.1%) nonparametric estimates of survival were lower than the expected survival by CCI (77.5%, p<0.0001). The 10-year nonparametric estimate of freedom from malignancy was 66.3%.

CONCLUSIONS

Immediate and long-term survival after on-pump cardiac surgery of patients formerly affected by lymphoma were worse than expected, according to universally used predictive scoring systems. There was an increased risk of malignant tumour.

Feasibility and efficacy of simultaneous off-pump coronary artery bypass grafting and esophagectomy in elderly patients

INTRODUCTION

To analyze the outcomes of off-pump coronary artery bypass grafting (OPCABG) and esophagectomy simultaneously for patients with coronary artery disease (CAD) and coexisting esophageal cancer.

METHODS

Twenty-two patients with CAD and coexisting esophageal cancer underwent combined surgical interventions were subjected to the study. OPCABG was performed first, followed by esophagectomy. All the corresponding data including clinicopathological characteristics and postoperative outcomes were all investigated.

RESULTS

All the combined procedures were performed successfully. The average number of grafts was 2.36. Tumors were located at the middle third of the esophagus in 5 patients, at the lower third of the esophagus in 8 patients, at the esophageal gastric junction (EGJ) in 9 patients, respectively. The operations were carried out through a left lateral thoracotomy approach in 21 patients while a median sternotomy and left lateral thoracotomy approach was used in 1 patient for his condition rapidly worsened. Postoperatively, pneumonia occurred in 4 patients (18.2%). During the follow-up, three patients died of cancer metastasis /recurrence (6, 18, 37 months) and one died of pneumonia (1 month). The cumulative 5 years survival rate is 52.9%.

CONCLUSIONS

The combined procedure of OPCABG and esophagectomy is a safe and effective treatment option for patients with severe CAD and esophageal cancer.

Concomitant off-pump coronary artery bypass and non-cardiovascular surgery

BACKGROUND

Reports on concomitant cardiac and non-cardiovascular surgeries have noted disadvantages in the use of extracorporeal circulation. We assessed the results of concomitant off-pump coronary artery bypass (OPCAB) and non-cardiovascular surgery, and compared them with isolated OPCAB results.

METHODS

Of 2,439 patients who underwent OPCAB between 1999 and 2014, 115 patients underwent concomitant OPCAB and non-cardiovascular surgery. Combined non-cardiovascular diseases included 63 malignant and 52 benign diseases. Concomitant non-cardiovascular surgeries performed were general (n=62), thoracic (n=47), orthopedic (n=3), urologic (n=2) and otolaryngologic surgeries (n=1). Operative results were compared between the OPCAB patients who underwent concomitant non-cardiovascular surgeries (group 1, n=115) and isolated OPCAB patients (group 2, n=2,251). Because preoperative characteristics of the two groups were different, a 1:2 propensity score-matched analysis was performed and operative results of the two matched groups were compared.

RESULTS

Operative mortality rates were 0.9% (1/115) in group 1 and 1.0% (22/2,251) in group 2 (P=0.909). Although there were differences in preoperative patient characteristics, postoperative complications, including atrial fibrillation (36.5% vs. 28.8%), perioperative myocardial infarction (MI) (4.3% vs. 5.2%), acute renal failure (1.7% vs. 4.9%), mediastinitis (0.9% vs. 0.8%), bleeding reoperation (0.9% vs. 2.9%), and respiratory complications (2.6% vs. 2.1%), did not show significant differences between the two groups. After a 1:2 propensity score-matched analysis, there were no statistical differences in operative complications between the two groups.

CONCLUSIONS

Concomitant OPCAB and non-cardiovascular surgeries were not associated with increased mortality and postoperative morbidities when compared with isolated OPCAB.

Cancer in heart disease patients: what are the limitations in the treatment strategy?

Cardiovascular disease and cancer are leading causes of morbidity and mortality, and can both be present in one patient. In patients with simultaneous disease, the most threatening disease should be treated first. This is usually heart disease, but this can pose specific problems. If percutaneous coronary intervention is preferred, bleeding and thrombotic tendencies have to be taken into account in the subsequent treatment of the malignancy. With coronary artery bypass grafting, the advantages and disadvantages of one- or two-stage procedures, and the use of extracorporeal circulation have to be balanced. Development of heart disease after treatment of malignancy could be due to radiotherapy and chemotherapy. The effects of these cancer treatments have to be taken into account for the treatment options of the heart disease and the postoperative prognosis.

Surgical management of coronary artery disease associated with malignancy

Surgical management of patients with combined coronary artery disease and malignancy remains a challenge. In this review the time of surgical intervention, whether to treat the malignancy or the coronary artery disease first, and which bypass technique should be used during myocardial revascularization are reviewed to determine the most optimal strategy to manage patients who require coronary surgical revascularization and present with an underlying malignancy.

Simultaneous nephrectomy and coronary artery bypass grafting through extended sternotomy

Background

The advances in surgical techniques, resuscitation and anesthesiology support over the last years have allowed simultaneous thoracic and abdominal operations to be made for cancer and concomitant severe heart vessel disease relieving the patient from several diseases simultaneously and achieving long lasting remission or cure.

Clinical case

A simultaneous nephrectomy and coronary artery bypass grafting procedure through extended sternotomy is reported. A 63-year-old man with severe coronary artery disease was found to have renal carcinoma.

Diagnosis

Postoperative pathological investigation of the tumor revealed the presence of renal cell carcinoma pT3a N0 M0, G2. Coronarography revealed advanced three-vessel coronary artery disease.

Treatment

We successfully performed a simultaneous curative surgery for renal carcinoma and coronary artery bypass graft surgery under cardiopulmonary bypass using a novel technique of extended sternotomy. Simultaneous surgery thus appears to be a beneficial and safe approach for the treatment of coronary artery disease and resectable renal cancer in carefully selected patients.

Detrimental effect of cardiopulmonary bypass (CPB) on malignant disease

Patients with coronary artery disease associated with malignancy are a difficult group of patients to treat. The ideal approach to manage them is still controversial. Both problems can be manage by either a combined or staged operation. The use of CPB during revascularization of the myocardium among patients with malignant disease, may have an effect on dissimination of malignant cells. This was observed among two of our patients. We believe that the use of off-pump technique to revascularize the myocardium is a safe approach and can be performed either in combined or staged surgery to resect malignant disease.
