Ten cases of post-inflammatory aneurysm of the thoracic aorta were studied morphologically using aortic wall and aortic valve tissue resected during the surgical repair of the lesions. Four cases of aortic aneurysm in Behcet's disease showed massive perivascular infiltration of the lymphocytes and plasma cells in adventitia and vasa vasorum. Fibrous obliteration of the vasa vasorum was seen, and neutrophilic infiltration was also associated in two cases with recurrent prosthetic valve failure. Three cases of aortic aneurysm associated with Takayasu's arteritis showed similar histologic features, but giant cells and histiocytic reactions were additional findings. Plasma cell infiltration was more pronounced compared to the Behcet's aortitis. One case of luetic aortitis showed a non-specific chronic inflammatory reaction with florid endothelial cell proliferation. One case of ankylosing spondylitis showed fibrous thickening at the periannular portion of the aortic valve cusps, but this finding was also seen in an aortic valve of a patient with Behcet's disease. One case without any disease association showed similar features of chronic inflammation with granuloma formation. The findings suggest that they have similar histologic features indistinguishable in terms of the clinical disease association, but a granulomatous reaction could be expected in Takayasu's arteritis.

Ischemic colitis is one of the most common intestinal ischemic injury in which more than 90% of patient are over 60 year-old. It results from impaired perfusion of blood to the bowel and is rarely caused by vasculitis such as systemic lupus erythematosus, polyarteritis nodosa, and Takayasu's arteritis. Takayasu's arteritis affects the aortic arch, medium-sized and large arteries but rarely involves inferior mesenteric artery. We report a case of Takayasu's arteritis involving inferior mesenteric artery which developed ischemic colitis in a 70 year old female. To the author's knowledge this is the first case report in Korea. A 70 year old woman who had suffered from Takayasu's arteritis for 5 years was admitted for sudden abominal pain and hematochezia. On sigmoidoscopy, there were multiple segmental longitudinal ulcerations around splenic flexure and diffuse hemorrhagic edematous mucosa from descending colon to sigmoid colon. On abdominal CT angiography, inferior mesenteric artery was not traced. We diagnosed it as ischemic colitis combined with Takayasu's arteritis. After the conservative treatment, abdominal pain and hematochezia disappeared. She was followed up to 2 years without recurrence of symptoms.

BACKGROUNDTakayasu's arteritis (TA) is a chronic idiopathic inflammatory disease that affects large and medium size arteries. The brachiocephalic trunk is the most frequently involved site in TA, and multi-vessel lesions are common. Surgical treatment includes vessel reconstruction surgery and percutaneous transluminal angioplasty (PTA). Herein, we report our preliminary experience with surgical treatment of cerebral ischemia caused by cervical arterial lesions due to TA.

METHODSFrom January 2000 to December 2007, 38 patients with cerebral ischemia caused by cervical arterial occlusive lesions due to TA were treated surgically. There were three males and 35 females, with an age range of 15 - 42 years (mean 26.5 years). All patients had operative repairs undertaken. Twenty eight patients received bypass operation and 10 patients received percutaneous transluminal angioplasty. One case with coronary stenosis received coronary artery bypass simultaneously. Patients were followed up for 11 months to eight years.

RESULTSThere were no peri-operative deaths in cerebrovascular reconstruction patients. Symptoms of cerebral ischemia were improved or cured in 25 of 38 patients. There was a low incidence of cerebral reperfusion syndrome. Two patients died at five and seven years after surgery due to heart failure. Another 8 patients (20%) required further surgery for stenosis (5 patients) or anastomotic aneurysms (3 patients). Percutaneous transluminal angioplasty was performed successfully for treatment of aortic and renal lesions. Repeated angioplasty for revascularization was performed in six PTA cases with restenosis after 5 - 24 months.

CONCLUSIONSWhen cerebral perfusion has potential to be affected by TA, a definitive corrective procedure is advised when the patient is relatively stable. Although the recurrence rate is very high, percutaneous transluminal angioplasty is the first choice procedure. Bypass operation is optimal for brachiocephalic-vessel involvement in TA. Cerebral reperfusion syndrome can be avoided by careful selection of the operation method and improved post-operative treatment.

OBJECTIVETo evaluate the clinical features, renal histopathology and therapeutic response to glucocorticoid and immunosuppressive agents in patients with glomerular disease associated with Takayasu arteritis (TA).

METHODSPatients with TA and renal biopsy-confirmed glomerular disease were investigated retrospectively. None of them had renal artery stenosis or occlusive changes.

RESULTSSix patients with glomerulopathy, accounting for 3.75% of the 160 TA patients admitted to our hospital at the same period, were analyzed. All of them were females with a mean age of 35.5 +/- 10.0 years. Four cases presented with lower extremity edema. Laboratory tests showed that one was nephrotic syndrome, three were nephrotic range proteinuria, and two of them had mild renal dysfunction. The other two patients were asymptomatic microscopic hematuria and proteinuria. Renal pathology revealed mild immunoglobulin A nephropathy in two cases, mild mesangial proliferative glomerulonephritis (GN), membranoproliferative GN, minimal change disease, and fibrillary GN in one case respectively. Five cases received glucocorticoids and cyclophosphamide therapy. Proteinuria and microscopic hematuria disappeared in 2 to 4 weeks after the initiation of therapy in three cases. The patient with membranoproliferative GN also reached complete remission of proteinuria and recovered renal function 6 months after the treatment.

CONCLUSIONSTA may induce glomerular disease as a part of its histological spectrum. Apart from ischemic glomerular disease, glomerular disease should be suspected when TA patients have microscopic hematuria or proteinuria, that may be therapeutically responsive to glucocorticoids and immunosuppressive agent in relative early phase.

Escherichia coli (E coli) O157 may cause abdominal pain and diarrhea followed by hematochezia. Most of cases resolve spontaneously after several days. Takayasu's arteritis affects medium- and large-sized arteries, aortic arch and its branch, and rarely affects inferior mesenteric artery. In case of Takayasu's arteritis with hematochezia, we must distinguish among ulcerative colitis, ischemic colitis, and infectious colitis with Takayasu's arteritis. We report a case of 17-year-old woman who suffered from hemorrhagic colitis by E. coli O157, and combined with leg claudication and abdominal pain by Takayasu's arteritis that affected abdominal aorta and inferior mesenteric artery. Sigmoidoscopy showed edematous, hyperemic mucosa and superficial ulcerations in the sigmoid colon. Abdominal CT scan showed diffuse submucosal edema, narrowing of distal abdominal aorta and inferior mesenteric artery. Hematochezia disappeared after the conservative treatment and leg claudication and abdominal pain disappeared after the aortic angioplasty.
