Acute myocardial infarctation in patients with critical ischemia underwent lower limb revascularization

Abstract

Background: Atherosclerosis is the main cause of peripheral artery occlusive disease (PAOD) of the lower limbs. Patients with PAOD often also have obstructive atherosclerosis in other arterial sites, mainly the coronary arteries. This means that patients who undergo infrainguinal bypass to treat critical ischemia have a higher risk of AMI. There are, however, few reports in the literature that have assessed this risk properly. Objective: The aim of this study was to determine the incidence of acute myocardial infarction in patients who underwent infrainguinal bypass to treat critical ischemia of the lower limbs caused by PAOD. Material and Methods: A total of 64 patients who underwent 82 infrainguinal bypass operations, from February 2011 to July 2012 were studied. All patients had electrocardiograms and troponin I blood assays during the postoperative period (within 72 hours). Results: There were abnormal ECG findings and elevated blood troponin I levels suggestive of AMI in five (6%) of the 82 operations performed. All five had conventional surgery. The incidence of AMI as a proportion of the 52 conventional surgery cases was 9.6%. Two patients died. Conclusion: There was a 6% AMI incidence among patients who underwent infrainguinal bypass due to PAOD. Considering only cases operated using conventional surgery, the incidence of AMI was 9.6%.

Posterior anesthesia for lower limb varicose veins: a case report with video

“…4 There are several techniques for treating varicose veins. [1][2][3] Being the most serious and operated on in the SUS system, they normally require anesthesia, with spinal anesthesia being the most used. When the patient does not have the saphenous vein removed, the patient can be operated initially in the prone position and later completed in the supine position.…”

“…Varicose veins are tortuous and dilated veins that appear due to diseased vessels that mainly affect the lower limbs. 1 Around 62% of women and 37% of men over 30 years of age in Brazil are affected by this disease. 1 Contrary to what you might think, varicose veins in the legs are not just an aesthetic problem.…”

The presence of a varicose vein indicates a diseased vein and is often the first sign of chronic venous insufficiency.…”

Evolução e qualidade de vida em pós-operatório de cirurgia vascular

“…Pacientes com esse quadro são mais suscetíveis a um IAM por conta do estresse cirúrgico com a produção aumentada de catecolaminas. Não por acaso, essa complicação desponta como importante causa de morte no perioperatório da cirurgia (Lins et al, 2013).…”

“…Nas pessoas com DAOP, também é mais comum se atestar casos de doença arterial coronariana (DAC). Em ambos os casos, as chances de o paciente necessitar de cirurgia são altas devido, principalmente, à aterosclerose (Lins et al, 2013).…”
