Risk Of Death

Abstract. Background: Diabetes mellitus increases the risk of ischaemic stroke in the general population but its impact on early outcome after the carotid endarterectomy (CEA) is controversial with conflicting results. Patients and methods: This prospective study includes 902 consecutive CEAs. Patients were divided into non-diabetic and diabetic groups and subsequently analysed. Early outcomes in terms of 30-day stroke and death rates were then analysed and compared. Results: There were 606 non-diabetic patients. Among 296 diabetic patients, 83 were insulin-dependent. The cumulative TIA/stroke rate was statistically higher in the diabetic group (2.6 vs. 5.7 %, P = 0.02). Stroke was more frequent in the diabetic group (2.0 vs. 4.4 %, P = 0.04) comparedto TIA (0.7 vs. 1.4 %, P = 0.45). Mortality was statistically more frequent in diabetic patients (0.2 vs. 1.7 %, P = 0.01). The 30-day stroke/death rate (2.6 vs. 5.7 %, P = 0.02) was also statistically higher in the diabetic group. Factors that were identified to increase risk of death and stroke in multivariate analysis were: use of insulin for blood glucose control (OR = 2.47, 95 % CI 1.61–4.68, P = 0.01), higher low-density lipoprotein cholesterol value (OR = 1.52, 95 % CI 1.15–2.22, P < 0.01), presence of coronary disease (OR = 2.04, 95 % CI 1.40–3.31, P = 0.03), peripheral artery disease (OR = 2.14, 95 % CI 1.34–3.65, P = 0.02), complicated plaque (OR = 1.77, 95 % CI 1.11–3.68, P = 0.03), contralateral carotid artery occlusion (OR = 2.37, 95 % CI 1.25–4.74, P = 0.02), shunt use (OR = 3.46, 95 % CI 1.18–7.10, P < 0.01), and among diabetic patients higher HbA1c levels (OR = 1.28, 95 % CI 1.05–1.66, P = 0.03). Clamp toleration was associated with lower risk of death and stroke rates (OR = 0.43, 95 % CI 0.23–0.76, P < 0.01). Conclusions: In our study, perioperative neurological complications and mortality were statistically higher in diabetic patients compared to non-diabetic patients during CEA. Further research will have to show whether other treatment modalities of carotid artery stenosis and better glycaemia and dyslipidaemia controlling in diabetics can reduce this risk.

Abstract. Background: Insufficient evidence exists to support the safety of carotid endarterectomy (CEA) following intravenous thrombolysis (IVT) for acute ischaemic stroke. Our study aimed to report a single-centre experience of patients treated over a five-year period. Patients and methods: Departmental computerised databases were interrogated to identify patients who suffered an ischaemic stroke and subsequently underwent thrombolysis followed by CEA. Mortality and stroke within 30 days of surgery were defined as the primary outcome end points. Results: Over a five-year period, 177 out of a total of 679 carotid endarterectomies (26 %) were performed in patients presenting with acute ischaemic stroke. Twenty-five patients (14 %) received IVT prior to CEA in the form of alteplase. Sixty percent of patients were male with a mean age of 68 years. Sixteen patients (64 %) underwent CEA within 14 days of IVT and the median interval between thrombolysis and CEA was 7.5 days (range, 3–50 days). One female patient died of a further intraoperative stroke within 30 days of surgery, yielding a mortality rate of 4 %. Two patients (8 %) suffered from cardiac complications postoperatively resulting in a short high dependency unit stay. Another two patients (8 %) developed local wound complications, which were managed conservatively without the need for re-operation. The median hospital length of stay was 4.5 days (range, 1–33 days). Conclusions: Our experience indicates that CEA post-thrombolysis has a low incidence of mortality. Further high quality evidence is required before CEA can be routinely recommended following IVT for acute ischaemic stroke.

Background: In the present study the perioperative complication rate is compared between high- and low-risk patients when carotid endarterectomy (CEA) is routinely performed under local anaesthesia (LA). Patients and methods: From January 2000 through June 2008 1220 consecutive patients underwent CEA under LA. High-risk patients fulfilled at least one of the following characteristics: ASA 4 classification, “hostile neck”, recurrent ICA stenosis, contralateral ICA occlusion, age ≥ 80 years. The combined complication rate comprised any new neurological deficit (TIA or stroke), myocardial infarction or death within 30 days after CEA, which was compared between patient groups. Results: Overall 309 patients (25%) were attributed to the high-risk group, which differed significantly regarding sex distribution (more males: 70% vs. 63%, p = 0,011), neurological presentation (more asymptomatic: 72% vs. 62%, p = 0,001) and shunt necessity (33% vs. 14%, p < 0,001). In 32 patients 17 TIAs and 15 strokes were observed. In 3 patients a myocardial infarction occurred. Death occurred in one patient following a stroke and in another patient following myocardial infarction, leading to a combined complication rate of 2,9% (35/1220). In the multivariate analysis only previous neurological symptomatology (OR 2,85, 95% CI 1,38-5,91) and intraoperative shunting (OR 5,57, 95% CI 2,69-11,55) were identified as independent risk factors for an increased combined complication rate. Conclusions: With the routine use of LA, CEA was not associated with worse outcome in high-risk patients. Considering the data reported in the literature, it does not appear justified to refer high-risk patients principally to carotid angioplasty and stenting (CAS) when LA can be chosen to perform CEA.
