Mural Thrombus (mural + thrombus)
Selected AbstractsSurgical Technique for Massive Mural Thrombus in the Left AtriumJOURNAL OF CARDIAC SURGERY, Issue 5 2007Masaru Yoshikai M.D. The fresh autologous pericardium was used to cover the roughened left atrial endocardium after the removal of the mural thrombus. This procedure seems useful to prevent not only the perioperative thromboembolism caused by the dislodgement of the fragmented small thrombus but also any long-term future thrombus formation by creating a smooth surface layer with the autologous pericardium. [source] Is It Safe to Initiate Selective Cerebral Perfusion with Normothermia?JOURNAL OF CARDIAC SURGERY, Issue 5 2005Mizuho Imamaki M.D. Cerebral circulation is isolated from systemic circulation to avoid cerebral embolization due to detachment of atherosclerotic material from the aorta, caused by the "sandblasting" effect of high-velocity jets of blood exiting the aortic cannula. However, neither the safety of SCP at normothermia nor the influence of extended SCP time has been sufficiently clarified. To clarify the safety of P-SCP, the comparison study of P-SCP and conventional SCP (C-SCP) was performed retrospectively. Methods: Fifty-seven patients (C-SCP group: 29 patients; P-SCP: 28 patients) underwent surgery between 1992 and 2002. Results: Nine (15.8%) in-hospital death occurred; 4 in the C-SCP group (13.8%) and 5 in the P-SCP group (17.9%) (NS). The SCP time was 136.6 ± 68.5 minutes in the C-SCP group and 195.8 ± 30.7 minutes in the P-SCP group (p < 0.05). One patient in each group exhibited postoperative neurological dysfunction. Conclusion: It may be little dangerous to initiate the SCP with normothermia. P-SCP may be useful in cases in which there is pedunculated atherosclerotic material, or mural thrombus in the ascending and arch aorta. [source] Mycotic pseudoaneurysm following a kidney transplant: A case report and review of the literaturePEDIATRIC TRANSPLANTATION, Issue 5 2009Ignacio Osmán Abstract:, Vascular complications represent a significant cause of morbidity and mortality following a kidney transplant. Pseudoaneurysms are rare, occurring in approximately 1% of cases. We present a 15-yr-old patient who received a kidney transplant in the right iliac fossa. Thirty-six days following the transplant, the patient was admitted to the hospital because of a marked increase in serum creatinine levels, arterial hypertension, scrotal edema, and lower right limb pain. The patient did not present fever or raised inflammatory markers. A pseudoaneurysm was diagnosed by means of a Doppler echography and a CT. By a selective arteriography of the right iliac artery, we placed a 8 × 5 cm stent to isolate the pseudoaneurysm, due to the high risk of an extensive defect occurring in the arterial wall. Forty-eight h later the patient underwent transplant nephrectomy. Seven days following surgery, the patient experienced febrile syndrome and therefore another CT was carried out which showed a large abscess around the stent. So we decided to perform another intervention in order to drain this abscess. Due to the extensive loss of the arterial wall where the prosthesis was largely exposed, we ligated the common iliac and external iliac arteries, removed the prosthesis and performed a femoro-femoral bypass with the usual subcutaneous positioning of the prosthesis (separate from surgical site). The stent and mural thrombus were sent for culture analysis and Candida albicans was observed. The diagnosis of a pseudoaneurysm in these types of patients continues to be considered as a surgical emergency by the majority of authors. Transplantectomy is the most frequently used treatment technique. Positioning a stent prior to transplantectomy avoids ligature of the iliac artery in the majority of cases. [source] | ||||||||||
