Intracardiac thrombi: Frequency,location, etiology,and complications: A morphologic review—Part III

Intracardiac thrombus may develop as a consequence of multiple underlying cardiac disorders. Left ventricular (LV) aneurysm following acute myocardial infarction has been associated with intra-aneurysmal thrombus and emboli. Part III of this 5-part article on intracardiac thrombus focuses on the frequency and consequence of thrombus associated with LV aneurysm.

A new approach for acute embolus occlusion of the superior mesenteric artery

Acute embolus occlusion of the superior mesenteric artery (SMA) either demonstrates a poor prognosis, or forces the patients to endure miserable postoperative dietary lives. Recently, we developed a new successful technique which reduced the length of the intestinal segment that had to be removed. The technique was as follows: (1) the distal end of the SMA was ligated to avoid perfusion of the necrotic segment, and (2) a Fogarty balloon catheter was inserted from the distal end of the SMA and then passed proximally to remove any remaining clots. Using the above-described technique on 3 cases from 1992 to 1994, we were thus able to shorten the length of the intestine that had to be removed and thereby greatly improve the patients' postoperative dietary lives.     

The efficacy of non-clamping selective cerebral perfusion in distal aortic arch aneurysm repair: Report of a case

Successful repair of a distal aortic arch aneurysm without aortic cross-clamping was carried out in a 74-year-old man, using a combination of special separate cerebral perfusion and retrograde coronary perfusion, termed non-clamping selective cerebral perfusion. We believe that satisfactory results following aortic arch surgery in elderly patients can only be achieved through the prevention of emboli derived from an aortic cross-clamping site, and shortened ischemic time of the vital organs.     

Surgical removal of a branch retinal artery embolus: a case report

A patient with embolic retinal artery occlusion of sixty-hour duration underwent a surgical procedure resulting in the removal of one embolus and the fragmentation with distal flow of a second. Visual acuity improved from counting fingers to 20/200 and was stable 3 months postoperatively.Supported in part by Public Health Service Grant EY02377, from the National Eye Institute, National Institutes of Health, Bethesda, MD     

胃癌脉管内癌栓中EGFRc-Met和Ki-67的相关性分析

目的:分析胃癌患者脉管内癌栓与EGFR、c-Met和Ki-67表达的关系及其对疾病预后影响.方法:检测EGFR、c-Met和Ki-67在88例胃癌组织,其中包括脉管内癌栓阳性者39例中的表达情况,分析脉管内癌栓阳性组与阴性组患者1年及3年生存率的差异.结果:脉管内癌栓阳性组中EG-FR、c-Met和Ki-67的强阳性表达率均高于脉管内癌栓阴性组,差异有统计学意义(P<0.05).脉管内癌栓阴性患者1年、3年生存率高于同期阳性组,差异有统计学意义(P<0.05).结论:EGFR、c-Met和Ki-67的表达与脉管内癌栓及患者预后密切相关,脉管内癌栓是胃癌患者预后不良的标志.     

Prophylactic placement of vena caval filters: A cautionary note

Greenfield filter placement in patients without deep venous thrombosis has been performed when such patients were felt to be at high risk for asymptomatic deep venous thrombosis and subsequent embolus. In this group placement is termed truly prophylactic to differentiate from placement in a patient with documented deep venous thrombosis which has not yet embolized. A retrospective review of Greenfield filter placement at five Dayton, Ohio, community hospitals over three years revealed 59 filters placed in 58 patients. Of these 90% were placed surgically and 10% percutaneously at an average cost of $4,141.00 per surgical procedure. Indications included traditional as well as true prophylaxis. A low morbidity and no mortality related to filter placement was observed. The high efficacy and safety of filter placement seen at large institutions is also found in our community hospital experience despite placement by physicians who perform the procedure infrequently. Although filter placement in patients at a high risk for silent fatal pulmonary emboli may prevent a rare mortality, widespread use of this modality for pulmonary embolus prophylaxis is costly and not without patient risk. We caution against the use of Greenfield filters for pulmonary embolus prophylaxis in patients without deep venous thrombosis until evidence of superior efficacy compared to other forms of prophylaxis can be demonstrated.
