Aortic rupture is a frequent cause of death in chest trauma. The coincidence with other associated severe lesions and the absence of clear cardiographic signs may induce to an important delay in the diagnosis. We report a case in which the late apparition of arterial hypertension expressed as an acute aortic coarctation syndrome pointed out the diagnosis. We review the pathogenic mechanisms of arterial hypertension in traumatic aortic rupture and the utility of different diagnostic procedures.

A population based study was carried out over a 25-year period (1972-1997) to disclose the clinical and pathological features of aortic dissection based on the analysis of 79 (71 acute and 8 chronic) consecutive cases of disease observed in an defined population of 106,000 inhabitants. Of the 79 patients 65 (82.3%) were admitted to hospital and 14 (17.7%) died out of hospital. Their ages ranged from 36 to 97 years (mean, 65.4 yrs), 49 (62.0%) were men and 30 (38.0%) were women with means 61.2 and 69.1 years, respectively. The male/female ration was 1.6:1. All but two operated patients died. The pain was the leading symptom. Every patients had some kind of cardiovascular and respiratory signs. Neurologic symptoms occurred in 27/65 (41.5%) patients. In five patients the clinical picture of abdominal catastrophe and in two patients renal failure occurred. The major vessels were affected in 32/75 (42.7%) autopsies. Aortic rupture were seen in 64/79 (81.0%) cases. Five spontaneous healings were observed. The hypertension, the advantaged age and the arteriosclerosis are regarded as the mean predisposing factors.

The term acute aortic syndrome comprises in addition to classic dissection also two recently described entities--penetrating ulcer and intramural haematoma. Forty-two necropsy cases of acute aortic syndrome were encountered during the last six years--41 dissections and one penetrating ulcer; the intramural haematoma was not seen. According to the DeBakey classification, there were 26 dissections of type I, 8 of type II, 1 of type IIIA, and 4 of type IIIB; in 2 cases the dissection was confined to the abdominal aorta. The dissection had a chronic character in four cases. Aortic rupture was found in 24 cases (59%), most frequently (19x) into the pericardial cavity. The aortic dissection continued into aortic branches in 25 patients (61%), causing stenosis/obstruction of coronary arteries in 7, of branches of the arch in 20, of abdominal arteries in 12, and of renal arteries in 17 patients, respectively. Histologically, there were degenerative lesions of the Erdheim type in the media of 10 aortas (from 21 completely examined). As possible risk factors for aortic dissection there appeared hypertension in 32 patients, anuloaortic ectasia in 11, saccular aneurysm ot the abdominal aorta in 6, family history of dissection in 2, Marfan syndrome in 2, prolaps of the mitral valve in 2, and bicuspid aortic valve in 2 patients, respectively. The aortic dissection was iatrogenic in 7 patients, presenting as a complication of a cardiosurgical or invasive cardiological procedure.
