From April 1981 to December 1988, a total of 23 patients were operated upon for the repair of an aneurysm of the descending thoracic aorta with a tridodecylmethylammonium chloride (TDMAC)-heparin-impregnated shunt. There were 20 men and 3 women. The ages ranged from 29 to 72 years with a mean of 52.3 years. The major pathological change of the aortic wall was medial cystic necrosis in 19 patients and atherosclerosis in 4. Among them, only 6 patients underwent elective surgery, while 17 patients underwent emergency operations with the surgical indication being shock in 4, oliguria in 3, persistence of chest pain in 2, massive hemoptysis in 1, rapid size progression of the aneurysm in 3, and impending rupture of the aneurysm in 4. During surgery, the aortic cross-clamping time ranged from 40 to 76 minutes with a mean of 54 minutes. Hospital death was limited to 2 patients with a mortality rate of 8.7%. Postoperative complications were noted in 5 patients, cerebrovascular accidents in 4 and transient paraparesis in 1. However, the clinical conditions recovered before those patients were discharged. The follow-up period ranged from 4 to 84 months with a mean of 32.3 months. Except for 1 patient who died of anaphylactic shock due to drug allergy, the other 20 survivors had an apparent improvement of their clinical status and life quality.

Between 1978 and 1992, 70 patients were operated for type B aortic dissection (tear in the descending aorta without involvement of the ascending aorta). 15/70 (21%) patients had an acute dissection (onset of symptoms < 24 h), 19/70 (27%) a subacute dissection (onset of symptoms < 14 days), and 36/70 (51) a chronic dissection (onset of symptoms > 14 days). The indications for surgery in cases of acute dissection were: hematothorax, oliguria, leg ischemia and persistent pain. Persistent hypertension was an additional indication in cases of subacute dissection. In large majority (93%) of chronic dissections the indication for surgery was enlarged aortic diameter. In 86% (60/70) graft replacement of the aorta was performed, in 6% (4/70) extra-anatomic bypass, in 3% (2/70) fenestration, in 3% (2/70) thrombendarterectomy, in 3% (2/70). The overall mortality was 17% (12/70); 27% of acute dissection, 26% for subacute dissection, and 8% for chronic dissection. The morbidity for acute dissection was 73%, of subacute dissection 43%, and of chronic dissection 12%. The most frequent complications were: leg ischemia (8 patients), renal failure (4 patients), paraparesis (4 patients) and sepsis (2 patients). No paraparesis was encountered in surgery of the chronic dissection. Conservative treatment was tried in all acute B-dissections, with surgical therapy being reserved for complications of the dissection, such as rupture, such as rupture, risk of rupture (hematothorax, large aortic diameter resp. expansion, persistent hypertension, persistent pain) or ischemia of distal vascular beds. Long-term survival for chronic type B dissections is good. Strong control of risk factors (hypertension) is essential.
