Carotid surgery in octogenarians: is it worthwhile?

Controversy surrounds the role of carotid endarterectomy in octogenarians. Although the prognosis of severe degree carotid stenosis is more ominous in the elderly, operative risk seems more important in the aged. To evaluate the presumed detrimental effect of advanced age on the mortality-morbidity of carotid endarterectomy, the authors reviewed their common experience with carotid surgery in patients aged 80 years or more. From 1980 to 1994, 129 octogenarians were operated on for occlusive carotid artery disease in two university hospitals. The data for these patients, 80 years of age and older (group 1) are compared to these for a large middle age group (less than 80 years) (group 2) operated by the same surgeons during that period. The baseline characteristics of both groups were similar, except for smoking, diabetes and previous myocardial revascularization, more prevalent in the younger age group. In the elderly group prophylactic surgery for asymptomatic stenosis was done in 36%, versus 40% of the middle aged patients, and for stroke in evolution in 8% versus 4% (p < 0.05). The perioperative stroke rate was 0.8% in the group older than 80 years, compared to 1.2% for non octogenarians (NS). The operative mortality was similar for both age groups (2.3 and 1.5 respectively). The long-term results gave a similar outlook for both age groups. The 5-year stroke-free rate reached 89% for group 1 versus 91% for group 2. The 5-year survival rate, however, was less for the elderly patients (47% versus 77%, mean follow-up periods of 30 and 49 months). These results suggest that carotid endarterectomy can be safely done in elderly patients, with a similar risk/benefit ratio as for the younger patients. Advanced age, by itself, is not to be considered as contraindication to carotid surgery.

Isolated atherosclerotic aneurysms of the iliac arteries.

Atherosclerotic aneurysms limited to the iliac arteries are rare and entail a high risk of rupture. To evaluate the efficacy of prophylactic surgery, we retrospectively studied 15 patients (13 men and two women; mean age 69 years) treated for isolated iliac aneurysms in the Department of Cardiovascular Surgery at the University Hospital of Liège over a period of 18 years. They had a total of 25 aneurysms (20 common iliac and five internal iliac). Six patients were treated electively and nine on an emergency basis for rupture. Five of the emergency patients (33%) died in the early postoperative period (< 30 days); in each case the aneurysm had ruptured and an emergency operation was performed (55.5% mortality in the ruptured iliac aneurysm group). On the other hand, all patients treated electively survived. Our study is comparable to other recent series in the literature, which also reported a high incidence of rupture and death in emergency operations. Prophylactic elective surgery is recommended for iliac aneurysms.

[Role of carotid surgery in the prevention of cerebral infarction].

A significant part of transient or permanent cerebral ischemic attacks (CIA) are due to arterio-arterial emboli issued from carotid plaques. Surgery for carotid disobstruction aims to take out emboligenic plaques by endarterectomy (associated to angioplasty or not). The adversaries of surgical treatment sustain two main assertions: 1. carotid stenoses are not very dangerous, because the definitive thromboses they create are easily compensated by the development of collaterals, so that the risk for stroke is low. 2. this low and late risk of spontaneous carotid thrombosis is not greater than the immediate one following carotid surgery. Those objections have been encountered in randomized North American studies (Nascet & Veterans) that have been published in 1991 and 1993. They show the usefulness of correctly done surgical correction as well as for symptomatic as asymptomatic stenoses. So do we it, presenting the results of our series (2.282 procedures in 1.868 patients). The results of our series show a low combined morbidity-mortality rate (1.7%), and a yearly stroke of 1.4%.

[An unusual case of clear-cell carcinoma of the pancreas].

This case of clear-cell carcinoma of the pancreas was a rare for three reasons: a) discovery: the investigation was indicated after sudden digestive hemorrhage revealed by melena and anaemia; b) morphology: the tumour began in the head with a spheric tumoural bud and a pediculated extension into the duodenum; c) pathology a clear-cell tumour similar to the type seen in renal localizations. Only one other case of such a primitive tumour was found reported in the literature.

Potential benefits of laparoscopic aorto-bifemoral bypass surgery.

BACKGROUND: This series aims to prove the positive impact of laparoscopic approach in aortofemoral bypass grafting. METHODS: It concerns a retrospective non randomized study comparing 58 consecutive patients treated with laparoscopic procedure (n = 30) and with a standard open procedure (n = 28) in a single center. The different operating times, the complications and the follow-up of these two groups are compared RESULTS: The demographics and angiographic data of the two groups were comparable. Operating time was longer in the laparoscopic group. However, we noticed a significant shorter hospitalisation stay (p < 0.0001) after the laparoscopic procedure with a mean 5.1 days. There was no significant difference of morbidity. CONCLUSION: We suggest that the trans-peritoneal approach is the best way in laparoscopic procedure in term of exposure and ergonomics. Laparoscopic aortofemoral bypass grafting is feasible, safe and effective. Shortening of operating time is observed as surgeon's experience grows.

Abdominal aortic aneurysms in octogenarians.

The decision on whether to operate or not abdominal aortic aneurysms (AAA) in elderly depends on the relative risk of the operation versus the natural course of the unoperated AAA. From January 1984 to December 996, 138 patients, aged 80 years and older, were referred to our department for an aneurysm of 40 mm or more (transverse diameter) of the infrarenal abdominal aorta (95 asymptomatic, 15 painful, and 28 ruptured AAA). For 58 patients with asymptomatic AAA, operation was denied at referral because of transverse diameter less than 50 mm (n = 21), patient refusal (n = 10) or unacceptable operative risk or poor general condition (n = 27). Thirty-four of these observed AAA were ultimately operated after a mean delay of 41 months because of aneurysm enlargement (n = 15), aneurysm tenderness (n = 6) or rupture (n = 13). Overall, 52 patients had immediate (n = 37) or delayed (n = 15) elective repair of their AAA, with an in-hospital mortality of 5.7%. Urgent operation was done for 21 patients with a painful AAA. Six patients died at hospital (28% mortality rate). Emergent surgery was applied to 41 patients with ruptured AAA (including 13 AAA who ruptured during surveillance). The operative mortality in this subgroup attained 68%. Follow-up for the 77 survivors and the 24 non-operative patients averaged 43 months. The 5-year survival (operative mortality included) is 47% for electively operated patients, 30% for urgently and 20% for emergently operated patients. For comparison, the 5-year survival of an age and sex matched Belgian population is 63%. For the 24 medically followed AAA, the 5-year survival was 33%. In six cases, the cause of death was rupture of the AAA. Of the 58 patients for whom operation was initially not considered, 19 (33%) presented AAA rupture (13 operated in emergency and 6 who never came to surgery). The operative outcome of AAA repair in octogenarians is less favourable than in the younger age group (3.6% mortality after elective repair, 44% after operation for AAA rupture, according to our institution data). The authors conclude that AAA surgery should not be denied to octogenarians on the basis of advanced age alone. They recommend a straightforward surgery for otherwise healthy octogenarians with AAA of 50 mm diameter, surveillance up to 60 mm for high-risk patients and no surgery for unfit, bedridden or demented patients.
