ABSTRACT
Objectives:To investigate the effect of TP 5 on the immune function and infection rate in patients undergoing cardiopulmonary bypass(CPB) operation. Methods:Ninety four patients were divided into two groups to observe the effect of TP 5 on the immune function and infection rate. Results:The immunological parameters in the TP 5 group was better than the control group, and postoperative infection was prevented. Conclusions:TP 5 can improve patients' cell mediated immunity and reduce infection rate.
ABSTRACT
Objective To investigate the indications and efficacy of endovascular stenting for the treatment of thoracic aortic aneurysm.Methods From March 2005 to October 2008,21 patients with Stanford type B aortic dissection,5 cases of pseudoaneurysm,and 2 patient with intramural hematoma complicated with ulcer of the aortic wall were treated by endovascular stenting under general(2 cases) or local(26 cases) anesthesia in our hospital.Medtronic Talent stent was employed in 10 cases,Medtronic Valiant stent was used in 12,and microinvasive straight-type stent was used in 6 patients.Results The operation was completed successfully in all of the 28 cases.Angiography showed that the gaps in the aorta were closed without endoleak.No patient had chest pain or neurological complications.The patients were discharged in(4.5?1.1) days(range 3-7 days).Five patients developed fever after the operation and were cured by indomethacin in one month.One week after the surgery,in 21 cases,CT scan showed enlarged aortic dissection,improved blood supply,thrombus in the false lumen of the thoracic aorta,and a false lumen in the abdominal aorta.In the 5 cases with pseudoaneurysm,CT scan confirmed that the rupture was closed with thrombus being detected in the lumen.The aortic ulcers that were detected in the 2 cases,who had intramural hematoma,were covered by the stents.Of the patients,a follow-up of(21.3?10.2) months(range 1-40 months) was available in 23 patients,who had no complications during the period.Conclusions Endovascular stenting is a simple,safe and effective method for Stanford type B aortic dissection,pseudoaneurysm,and intramural hematoma,resulting in quick recovery,less complications,and short hospital stay.
