Background: This study examined mid-term outcomes of valve surgery in the elderly, and focused on the difference in outcomes between isolated and combined valve surgery.
Methods: From January 2012 to June 2016, 113 consecutive patients aged 75 years and older underwent valve surgery. In all, 60 underwent isolated valve surgery (Group I), and 53 underwent combined valve surgery (Group C) involving the combination of any valve procedures or valve surgery with concurrent other procedure. Short- and mid-term outcomes were compared between the two groups.
Results: There was no significant difference in length of intensive care unit stay (2.8 days in Group S vs. 4.2 days in Group C, p = 0.08), hospital stay (16.2 vs. 18.7 days, p = 0.22), and mechanical ventilation (11.2 vs. 15.0 hours, p = 0.28). Neither was there any significant difference in operative mortality (1.6% vs. 5.6%, p = 0.25) nor morbidity (8.3% vs. 9.4%, p = 0.83) between the two groups. Actuarial survival rates at 1 and 3 years were 98.3% in Group S and 92.0% in Group C (log-rank p = 0.126).
Conclusion: Once patients have tolerated combined surgery during the early postoperative period, good survival rates equaling those of isolated valve surgery can be expected.
Purpose: Early antithrombotic therapy after bioprosthetic aortic valve replacement (AVR) is controversial. This study aimed to retrospectively compare between warfarin and aspirin treatment in the 3 months after bioprosthetic AVR for elderly patients more than 60 years old, and to determine the optimal antithrombotic therapy.
Methods: This retrospective study included 479 patients in single center from January 1994 to June 2014. Patients were divided into two groups (Wa group, warfarin; As group, aspirin). We searched our computerized clinical database for thromboembolic or bleeding events. Propensity score analysis was conducted to adjust for selection bias.
Results: All patients, except one patient, were followed-up in the out-patient department for 3 months after the operation. In all, 86 propensity-matched patient-pairs were derived. Early operative outcomes were similar in both the groups. There are one patient of thromboembolic event and three patients of bleeding events, but the prevalence was not significantly different (p >0.999).
Conclusion: The incidence of thromboembolic and bleeding events during early 3 months after bioprosthetic AVR were similar in Wa and As groups. If the patient does not have indications of warfarin, early antithrombotic therapy with aspirin only may be easier and more feasible for elderly patients.
Background: Peripheral arterial disease (PAD) affects 3%–10% of the population before the age of 70 years and 15%–20% after that age.
The aim of the study was to compare the incidence of complications and secondary interventions in patients who underwent each type of treatment.
Methods: We analyzed 734 medical records of the Department of Surgery at the 4th Military Teaching Hospital in Wroclaw, In total, 394 were operated on with open surgery; an endarterectomy (59.39%), a vascular prosthesis implantation (31.01%), or both of these techniques (6.6%), and 340 patients had angioplasty with (50.59%) or without stenting (49.41%).
Results: There were no statistically significant differences in the incidence of corresponding complications. The exception was the infection of the wound; significantly fewer were reported in the case of endovascular procedures (p = 0.0087). There were 12 occasions (3.53%) during endovascular surgeries when intraoperative conversion or re-operation using the open method occurred. In the case of open surgery, the mean hospital stay was 7.77 days (median: 8, mode: 8), while for endovascular management it was equal to 4.68 days (median: 4, mode: 3), p <0.0001.
Conclusion: The endovascular method results in a similar re-operation rate and number of complications as open surgery.
Background: Multiple studies have compared on-pump coronary artery bypass (ONCAB) grafting with off-pump coronary artery bypass (OPCAB) grafting, but the optimal surgical strategy has yet to be established. Furthermore, there is limited evidence regarding mid-term graft patency rates.
Methods: Between April 2001 and March 2014, 365 consecutive patients underwent isolated coronary artery bypass grafting (CABG; male: 75%; mean age: 69 ± 10 years). After propensity-score-matched analysis, we assessed the results of 67 patients in each group (ONCAB: group A, OPCAB: group B). The mean follow-up period of graft patency and survival rate was 35 ± 37 months and 54 ± 47 months, respectively.
Results: There were no significant differences in baseline characteristics between the two groups. There was a trend for an increased number of distal anastomoses in group B as compared to group A (group A vs. group B: 3.8 ± 1.1 vs. 4.1 ± 1.6, P = 0.17). The total graft patency rate was tend to be lower in group A, but not statistically significant (group A: 156 months, 45.2%; group B: 96 months, 72.6%; P = 0.21). There was no difference for survival and major-adverse-cardiac-and-cerebrovascular-events (MACCE) free rate (P = 0.42 and 0.76, respectively).
Conclusion: Propensity-score-matched analysis revealed no difference in mid-term survival rate, MACCE free rate, graft patency rates, and number of distal anastomoses between ONCAB and OPCAB groups.
Chemotherapy with bevacizumab followed by surgery is now a viable treatment option for pulmonary metastasis from colorectal cancer (CRC). We herein report two cases of late-onset pulmonary fistula after resection of pulmonary metastasis from CRC following perioperative chemotherapy with bevacizumab. One patient suffered from a late-onset pulmonary fistula that occurred 3 months after pulmonary resection, which was treated with chest drainage and pleurodesis. The other patient suffered from a pulmonary fistula after three cycles of chemotherapy with bevacizumab after pulmonary resection, and underwent surgery to treat the fistula.
This report presents a rare case involving a patient with a giant leiomyoma originating from the mediastinal pleura. The patient underwent a medical examination, and chest radiography revealed a giant tumor. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a well demarcated, heterogeneous mass which seemed to originate from the posterior mediastinum. Positron emission tomography (PET) showed the uptake of this tumor with a standardized uptake value of 4.9. We suspected that this tumor was a solitary fibrous tumor, and the patient underwent a surgical resection. Intraoperative exploration revealed a well-encapsulated tumor measuring 15 × 11 cm that appeared to originate from the mediastinal pleura. Immunohistochemical findings revealed a benign leiomyoma. We finally diagnosed the patient with a mediastinal leiomyoma. The present report describes CT, MRI, and PET findings of leiomyoma, and presents a review of relevant literature.
Trifecta is a stented bioprosthetic heart valve with a bovine pericardial sheet externally mounted on a titanium stent. This valve is applied only for aortic valve replacement (AVR), providing excellent hemodynamics and extremely low incidence of structural valve deterioration (SVD). A 76-year-old woman presented with dyspnea on effort 24 months after AVR with a 21-mm Trifecta valve. Echocardiography revealed severe aortic regurgitation with prolapse of a cusp of Trifecta valve, which suggested that she developed acute heart failure due to early SVD. In the operation, Trifecta valve had a cusp tear near the commissure with circumferential fibrous pannus ingrowth only at the inflow side. There was neither calcification nor infection. The Trifecta valve was successfully replaced with a new porcine bioprosthesis.
We describe our approach to resect a Pancoast tumor with thoracoscopic assistance in a partitioned incision. We used the LigaSure vessel-sealing system under thoracoscopy in chest wall resection for Pancoast tumor. This approach is of great utility: easy-to use and less invasive for Pancoast tumor resection.
