Thromboembolic obstruction of the renal artery is a serious clinical problem, but rarely diagnosed. The diagnosis is not usually established until irreversible renal parenchymal damage occurs. Here, we present a case of renal artery thromboembolism in a patient who had atrial fibrillation and was treated by selective intra-arterial infusion of tissue plasminogen activator (TPA). A 69-year-old male was admitted to our hospital with a one-hour history of palpitation and epigastric pain. He had inferior myocardial infarction and percutaneous coronary intervention to the right coronary artery two weeks before. Coronary angiogram was performed, and no significant stenosis was detected. One hour later, epigastric pain spread to the left flank region. Spiral computerized tomography showed occlusion of the left renal artery. Emergency abdominal angiography was performed, and selective intra-arterial infusion of TPA was started promptly. The abdominal pain disappeared, and urine output remained adequate. Forty-eight hours later, angiographic follow-up confirmed the complete lysis of the thrombus in the left renal artery. No renal or hemorrhagic complications were observed, and the patient was discharged four days later with normalized renal function on oral anticoagulation.
We present a patient who underwent endoscopic retrograde cholangiopancreatography procedure for bile duct stone removal and sphincterotomy. Upon completion of the procedure, the patient experienced severe chest pain. Because myocardial infarction was the likely diagnosis, we immediately performed a coronary angiography, which identified severe coronary lesions without any total occlusion. Being skeptical of the possible cause, we searched for alternative causes and interestingly found pneumothorax, pneumomediastinum, and retro-intra-abdominal free air. This rare complication is particularly important for a cardiologist because they should be aware of such a complication, and correlation with the symptoms and coronary lesions should always be made.
Ischemic mitral regurgitation (IMR) is an important risk factor in coronary artery bypass grafting (CABG) operations. The decision to perform concomitant mitral annuloplasty along with the CABG depends on the surgeon's choice. The aim of this study was to evaluate the results of posterior annuloplasty procedures with autologous pericardium performed in patients with midadvanced and advanced functional ischemic mitral regurgitation.Study participants were 36 patients with IMR (mean age 59 +/- 10 years) who underwent posterior pericardial annuloplasty and CABG operations between 2002 and 2007. Preoperative and postoperative (mean follow-up 18 +/- 1 months) MR grade, left atrium diameter, left ventricle end systolic diameter, left ventricle end diastolic diameter, left ventricle ejection fraction, and mitral valve gradients were measured with transthoracic echocardiography.There was one late mortality (2, 8%) but none of the patients required reoperation for residual MR. We did not observe thromboembolism, bleeding, or infective endocarditis. The mean MR grade decreased from 3.4 +/- 0.5 to 0.5 +/- 0.6 (P < .01), left atrium diameter decreased from 45.3 +/- 5.5 mm to 43.2 +/- 3.8 mm (P < .01), left ventricle end diastolic diameter decreased from 53.2 +/- 5.6 mm to 50.9 +/- 5.5 mm (P < .01), and left ventricle end systolic diameter decreased from 39.7 +/- 5.8 mm to 34.6 +/- 6.5 mm (P < .01), whereas mean left ventricle ejection fraction increased from 37.9% +/- 6.1% to 43.7% +/- 7.3% (P < .01). In the late postoperative term, the functional capacity of the patients increased from mean New York Heart Association class 2.6 +/- 0.9 to 1.1 +/- 0.5. We did not observe any gradient in the mitral valve preoperatively in any patient, but in the follow-up, the mean gradient increased to 1.3 +/- 2.1 mmHg (P < .01).Posterior pericardial annuloplasty with CABG in the treatment of IMR provides efficient mitral repair and significant decrease in the left atrium and left ventricle diameters, and provides a significant increase in left ventricular function. These results show IMR to be as effective as the other annuloplasty techniques. IMR is performed with autologous material and therefore does not entail any risk of complications from prosthetic material and is highly cost-effective.
