IntroductionOver the years, operability criterias for cardiac surgery has been enhanced. Therefore, averege age of operated patients and co-morbidities have increased. 1) Cerebral injury is one of the most important complications of cardiac surgery which may cause mortality, morbidity, increased hospital costs and impaired quality of life. Perioperative cerebral injury includes stroke that occurs in 1.5% to 5.2% of patients, encephalopathy affecting 8.4% to 32% of patients. 2) Cognitive dysfunction has been reported in approximately 50% of patients at discharge, 36% at 6 weeks, 26%-33% at one year, and 42% at five years. 3,4) Pre-exisiting atherosclerotic plaque, thrombogenesis from the foreign surfaces of cardiopulmonary bypass, air from the cardiopulmonary bypass circuit, and pericardial fat globules are tought to be primary predictors of cognitive decline by creating microemboli during Purpose: The purpose of this study was to research the use of near-infrared spectroscopy (NIRS) on the neurocognitive functions in the patients undergoing coronary artery bypass grafting (CABG) with asymptomatic carotid artery disease. Methods: The study design was carried out with the participation of 79 patients in a prospective, randomized and double blind control method. The patients were separated into two groups as NIRS (n = 43) and no NIRS (n = 36). A neurocognitive test was applied preoperatively and postoperatively to all patients before discharge. Cognitive functions were evaluated by applying the Montreal Cognitive Assessment test (MoCA). Results: The decrease in the postoperative score of mean MoCA in no NIRS group was statistically significant when compared to preoperatively (p <0.001). Postoperative mean MoCA score was found to be significantly higher in NIRS group (NIRS: 26.8 ± 1.9 vs. no NIRS: 23.6 ± 2.5, p <0.001). It has been determined that there was a moderately positive significant correlation between the increase in the NIRS used patients (%) and increase in the MoCA score of the patients (r = 0.59, p <0.001). Conclusion: Intraoperative NIRS usage in the patients undergoing CABG with carotid artery disease might be useful due to its postoperative positive effects on the cognitive functions.
Hypercholesterolemia is related to increased risk of aortic valve calcification in patients with degenerative and congenital etiology. Preventive treatment of hypercholesterolemia could play an important role to decrease or inhibit development of aortic valve calcification.
We analyzed cases of re-exploration for bleeding after 19,680 open heart operations performed between January 1995 and January 2009 to determine the risk factors for mortality and morbidity. Half of the 282 patients reexplored had nonsurgical causes of bleeding. The patients were grouped according to the timing of reoperation, early re-exploration being on the day of the operation. Mortality, total morbidity, and the need for transfusion of any blood product were compared between the early and late re-exploration groups. Most patients (77.7%) were reexplored early. Overall mortality was 8.5% (24 patients). Mortality, total morbidity, renal, gastrointestinal, neurologic and infectious complications, and low cardiac output differed significantly between the 2 groups. Significant predictors of mortality were old age, female sex, left ventricular dysfunction, noncoronary operations, and delayed reoperation. Predictors of morbidity were old age, preoperative dialysis, tobacco use, chronic lung disease, and delayed reoperation. No factors were found to be associated with the need for transfusion.
The COVID-19 pandemic has presented a great challenge for the healthcare systems and healthcare workers worldwide. The resources and the infrastructure of the healthcare systems are reorganized to provide care for abundant number of pandemic patients. All elective procedures and treatments have either cancelled or postponed. Treatment of lower extremity ulcers may be misclassified as non-essential during this pandemic; however, without regular best wound care, these ulcers are at a great risk of becoming quickly infected, which may lead to an increased rate of septicemia, amputations, and even deaths in this fragile patient population. In this review, we discuss the treatment strategies for lower leg ulcers and vascular pathologies during pandemic and provide an algorithm for triage which may be a useful guide for vascular surgeons.
The tethering area, coaptation height, and distance between the commissures decreased significantly, thus posterior leaflet segment 2 plication in addition to ring annuloplasty may be the optional procedure to ensure freedom from moderate or severe mitral regurgitation.
SummaryGiant aortic aneurysm is defined as an aneurysm of the aorta of greater than 10 cm in diameter. This rare condition is associated with a high risk of morbidity and mortality and it may lead to fatal complications such as rupture and/or dissection if not managed with proper surgical planning and expertise. Other than atherosclerosis, the main causes of giant ascending aortic aneurysms include Marfan and Ehlers–Danhlos syndromes. Herein we report on a young male patient who had had an aortic valve replacement five years earlier due to a bicuspid aortic valve leading to aortic failure, accompanied by aortic coarctation. He had an aneurysmal expansion rate of 1.81 cm/year to reach a final aneurysmal diameter of 13.25 cm, which, to our knowledge, represents the largest size ever reported in the literature for such lesions, and in which the redo and aneurysmal wall were adjacent to the sternal margins.
Background: We aim to share our popliteal sciatic nerve block (PSB) experience, which we applied to diabetic and nondiabetic patients in the operating room of our hospital.
Methods: The patients who underwent PSB for foot and ankle surgery between October 1, 2021, and December 31, 2021, in Sakarya University Training and Research Hospital were evaluated retrospectively. All nerve blocks were administered by a single anesthesiologist. Demographic data of the patients and the duration of the operation, the type of operation, the time of application of the nerve block, whether it was single or bifurcation block, and the onset times of motor and sensory block were also recorded in the perioperative period.
Results: It was determined that PSB was applied to 49 patients over a 3-month period. The mean age of the patients was 61.33 ± 14.03 years, and 12 patients (24.5%) were women. The reason why the patients were operated on was amputation in 21 (42.9%) and wound debridement in 27 (55.1%). There were 37 patients in the diabetic group and 12 patients in the nondiabetic group. There was no significant difference between the two groups in terms of demographic data and operation characteristics, but it was observed that there was a significant difference in both sensory and motor block formation times between the two groups (P < .001).
Conclusions: In conclusion, we think that popliteal sciatic nerve block is easy to apply, the complication rate is low, and it is a suitable anesthesia method for patients who will undergo day surgery for foot ulcer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
