[Show abstract][Hide abstract] ABSTRACT: Although classic type A and B aortic dissections have been well described, less is known about the natural history of penetrating atherosclerotic ulcers of the thoracic aorta. This study differentiates penetrating ulcer from aortic dissection, determines the clinical features and natural history of these ulcers, and establishes appropriate correlates regarding optimal treatment.
A retrospective review of patient records and imaging studies was conducted with 198 patients with initial diagnoses of aortic dissection (86 type A, 112 type B) at our institution from 1985 to 1997.
Of the 198 patients, 15 (7.6%) were found to have a penetrating aortic ulcer on re-review of computed tomographic scans, magnetic resonance images, angiograms, echocardiograms, intraoperative findings, or pathology reports. Two ulcers (13.3%) were located in the ascending aorta; the other 13 (86.7%) were in the descending aorta. In comparison with those with type A or B aortic dissection, patients with penetrating ulcer were older (mean age 76.6 years, p = 0.018); had larger aortic diameters (mean diameter 6.5 cm); had ulcers primarily in the descending aorta (13 of 15 patients, 86.7%); and more often had ulcers associated with a prior diagnosed or managed AAA (6 of 15 patients, 40.0%; p = 0.0001). Risk for aortic rupture was higher among patients with penetrating ulcers (40.0%) than patients with type A (7.0%) or type B (3.6%) aortic dissection (p = 0.0001).
Accurate recognition and differentiation of penetrating ulcers from classic aortic dissection at initial presentation is critical for optimal treatment of these patients. For penetrating ulcer, the prognosis may be more serious than with classic type A or B aortic dissection. Surgical management is advocated for penetrating ulcers in the ascending aorta and for penetrating ulcers in the descending aorta that exhibit early clinical or radiologic signs of deterioration.

[Show abstract][Hide abstract] ABSTRACT: A 25-year-old Japanese woman had both ulcerative colitis and Takayasu's disease and was positive for HLA-A24, BW52, and DR2. She was found to have thickening of the wall of the carotid artery on contrast-enhanced computerized tomography of the neck and chest. Prednisolone, beraprost, and sulfapyridine achieved rapid remission of both diseases.

[Show abstract][Hide abstract] ABSTRACT: Clinically, penetrating atheromatous ulceration of the aortic wall may be confused with either symptomatic thoracic aneurysm or classic spontaneous aortic dissection. Aortography and computed tomographic (CT) scanning of the thoracic aorta provide specific diagnostic information which permits one to distinguish this lesion from atherosclerotic aneurysm and classic dissection. Hallmarks of findings on aortography and CT scan include the presence of the ulcer and an intramural hematoma. Since the findings may be disarmingly subtle, the potentially progressive and serious nature of this condition may remain unappreciated. Recognition of the penetrating atheromatous ulcer and distinguishing it from aortic dissection arising just distal to the origin of the left subclavian artery is mandatory. Resection of only a conservative segment of the proximal descending aorta suffices for classic dissection in the upper descending thoracic aorta, but the penetrating aortic ulcer requires graft replacement in the area of the ulcer and intramural hematoma.
