1/4. Intestinal infarction in rheumatoid arthritis. Three cases due to unusual obliterative vascular lesions.During a ten-year period, we observed three patients with complicated rheumatoid arthritis (RA) and bowel infarction in which the distal mesenteric vessels were occluded by proliferative endarteritis characterized by intimal proliferation, without vessel wall necrosis or inflammation. Proliferative endarteritis was originally described in patients with RA and digital infarcts and has only rarely been noted in patients with visceral infarcts. Our three patients' pathologic features suggested that these vascular lesions were progressive and rendered patients vulnerable to bowel infarction during periods of decreased cardiac output. Two of the three patients had intestinal infarction without clinical or pathologic evidence of systemic vasculitis. Proliferative endarteritis of visceral arteries rarely causes morbidity and mortality in patients with RA.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/4. femoral artery infection complicating intraaortic balloon pumping.Infection of the femoral artery (endarteritis) complicating intraaortic balloon pumping has not been reported. Most reports of complications with this pump have not emphasized wound infection. Whether the balloon is inserted by open or percutaneous technique, infection remains a problem. During the past 7 years, 32 of 50 patients (64 percent) who had intraaortic balloon pump insertion survived balloon removal. In four patients, wound infection of the groin developed with involvement of the femoral artery. sepsis was due to P. aeruginosa in three patients and E. cloacae in one. All patients required variable degrees of resection of the infected femoral artery wall. One had successful arterial reconstruction with vein patch angioplasty alone after debridement of the vessel wall. In a second patient, resection of the common femoral artery with interposition of a saphenous vein that had been reconstructed to enhance its diameter to that of the femoral artery was accomplished. Dehiscence of a vein patch angioplasty occurred in the remaining two patients with resultant hemorrhage. Further resection of the femoral artery was required with femoro-femoral saphenous vein grafting in one patient and iliofemoral vein grafting in another. Tissue coverage of the reconstructed vessel was best accomplished using a tensor fascis lata myocutaneous flap. All patients survived the infection without amputation.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/4. Herpes zoster vasculitis: demonstration by MR angiography.A patient presented with multiple cerebral infarcts in various vascular territories after having been treated for herpes zoster ophthalmicus. magnetic resonance angiography demonstrated multiple focal stenoses involving the proximal intracranial vessels which corresponded to endarteritis at autopsy.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
4/4. Thrombendarteriitis pulmonalis carcinomatosa Ceelen: an immunohistological investigation.A 65-year-old woman died in sudden right heart failure caused by thrombendarteriitis pulmonalis carcinomatosa Ceelen 16 months after resection of a rectal carcinoma. autopsy disclosed a complex picture of multiple tumour cell emboli in small pulmonary arteries associated with local thrombosis and thrombus-associated vessel wall reaction. This was characterized by movement of medial muscle cells into the thrombus. In addition, affected vessels showed a prominent perivascular tumour-related infiltration by lymphocytes which are identified immunohistochemically as CD3-reactive T-cells.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
