Outcomes of urgent carotid endarterectomy for stable and unstable acute neurologic deficits

OBJECTIVE The aim of the study was to assess the outcomes of carotid endarterectomy (CEA) performed in an urgent setting on acutely symptomatic patients selected through a very simple protocol. METHODS From January 2002 to January 2012, 193 symptomatic patients underwent CEA. Of these, 90 presented with acute symptoms, and after a congruous carotid stenosis was identified, underwent urgent operations (group 1): 27 patients had transient ischemic attack (group 1A), 52 patients had mild to moderate stroke (group 1B), and 11 patients had stroke in evolution (group 1C). The remaining 103 patients with a nonrecent neurologic deficit were treated by elective surgery in the same period (group 2). End points were 30-day neurologic morbidity and mortality. RESULTS The median delay of urgent CEA (U-CEA) from deficit onset was 48 hours (interquartile range, 13-117 hours). Groups 1 and 2 were comparable in demographics. Acute patients showed a higher rate of stroke at presentation (70% vs 37%; P = .001) and of history of coronary artery disease (30% vs 13.5%; P = .007). Acute patients sustained six postoperative strokes (6.6%). Neurologic outcomes were correlated to clinical presentation: no strokes occurred in group 1A patients, and 5.8% group 1B patients and 27.3% group 1C patients had postoperative stroke (P < .01). Postoperative mortality was 4.4% for U-CEA: one fatal myocardial infarction, one intracranial hemorrhage, and two thromboembolic strokes. Elective patients sustained four postoperative strokes (3.9%), with one death (0.9%) as a consequence of hyperperfusion cerebral edema. U-CEAs performed ≤48 hours from symptom onset had a lower postoperative stroke rate than those performed >48 hours (4.4% vs 8.8%; P = .3). Among patients presenting with a stroke (group 1B), the National Institutes of Health Stroke Scale (NIHSS) assessment at discharge showed improvement in 79% (although only 25% had ≥4 points in reduction), stability in 17%, and deterioration in 4%. Patients with moderate stroke were slightly better in NIHSS improvement than those with mild stroke (median NIHSS variation at discharge, -3 vs -1; P = .001). CONCLUSIONS Our results with U-CEA confirm that this population has a higher risk profile compared with elective surgery. The type of acute presentation is correlated with perioperative risk. U-CEA was safe when performed on patients presenting with transient ischemic attack. An acceptable complication rate was achieved for patients with minor to moderate strokes. The poorest outcomes occurred in patients presenting with stroke in evolution: U-CEA in these patients should be offered with extreme caution, although we are aware that a conservative treatment may not grant a better prognosis.

Seat belt injuries of the abdominal aorta in adults--case report and literature review

Blunt abdominal trauma with major vascular involvement is found to be rare. Although few series have been reported in the literature, the true incidence of blunt abdominal aortic injury is unknown. Different modalities of blunt trauma may occur among civilians with steering wheel and seat belt injury secondary to motor vehicle accident the most frequent. Mechanical forces produce variable patterns of injury; therefore, the onset of signs and symptoms can be different. Dissection and thrombosis of the abdominal aorta have been frequently described among seat-belted adult patients with major vascular involvement. The associated abdominal viscus and/or vertebral lesions must always be taken into account. Prompt diagnosis allows adequate surgical treatment. We present the case of a 66-year-old woman, restrained front passenger involved in a motor vehicle collision, who had small bowel transection, vertebral fractures, and aortic partial occlusion below inferior mesenteric artery with bilateral iliac artery involvement. Along with the case reported, the purpose of this study is to highlight and compare features and management of the previous cases described in the English literature.

Comparison of posterior and medial approaches for popliteal artery aneurysms

BACKGROUND Long-term results of the posterior approach (PA) for the treatment of popliteal artery aneurysms are lacking in the literature. We reviewed our experience during a 13-year period in patients with popliteal artery aneurysms, comparing those treated through a PA with those operated on through a standard medial approach (MA). METHODS Clinical data of all patients treated between February 1998 and October 2011 were retrospectively reviewed and outcomes analyzed. The Kaplan-Meier method was used to estimate survival, and χ(2), Wilcoxon, and log-rank tests were used for analysis. RESULTS A total of 77 aneurysms were treated in 65 patients (64 men). Mean age was 68 years (range, 48-96 years). Thirty-six aneurysms were asymptomatic (47%). Mean sac diameter was 2.8 ± 1 cm. A PA was used in 43 PAAs (55%) and an MA in 34. The PA and MA patients differed significantly in age (median being older), smoking history (more frequent in PA), and renal insufficiency and cerebrovascular disease (higher for MA). In 42 cases the aneurysm was symptomatic (54.5%) for chronic limb ischemia, with intermittent claudication in 18 patients, acute ischemia in 17, blue toe syndrome in 3, compression on adjacent structures in 3, and rupture with severe acute pain in 1. All PA repairs consisted of aneurysmectomy with an interposition graft with end-to-end anastomoses; among MA repairs, 22 interposition grafts and 12 bypasses were performed. A polytetrafluoroethylene graft was used in 54 cases. Five patients had an early thrombosis (two PA and three MA). No perioperative deaths occurred. Two patients sustained a permanent (PA) and a temporary (MA) peroneal nerve lesion. There were no early amputations. The median in-hospital stay was longer for MA (10 days) than for PA (7 days; P = .02). Median follow-up was 58.8 months (range, 5 days-166 months). Nine patients died during follow-up of unrelated causes. The 5-year primary and secondary patency rates were 59.6% ± 8.6% and 96.5% ± 3.4%, respectively, for PA, and 65.1% ± 11.1% and 79.4% ± 9.7%, respectively, for MA (P = .53 for primary patency rate and P = .22 for secondary patency rate). Limb salvage was 100% at 5 years and 93.3% ± 6.4% at 10 years for PA and 91.1% ± 6.3% at both time points for MA (P = .28). CONCLUSIONS PA and MA both achieved satisfactory results in primary and secondary patency rates, as well as limb salvage, during long-term follow-up. The differences between the two groups were small and not statistically significant. PA was burdened by similar postoperative nerve and wound complications compared with MA. The in-hospital stay after PA was significantly lower.

Fast-track in abdominal aortic surgery: experience in over 1,000 patients.

BACKGROUND Fast-track recovery programs have led to reduced patient morbidity and mortality after surgery. Minimally invasive surgery and anesthesia, with programs of early postoperative recovery are the main aspects of fast-track recovery programs. The optimization of pain control, early mobilization, and oral feeding allows for a rapid functional rehabilitation, which leads to minor morbidity and early discharge from the hospital to home. METHODS We enrolled all nonemergent patients treated for elective abdominal aortic surgery for an aneurysm or obstructive disease from April 2000 to June 2014. The fast-track protocol was applied to all these patients. A transperitoneal aortic approach was used through a left subcostal incision and was complemented with epidural anesthesia-analgesia and a protocol of early rehabilitation. RESULTS A total of 1,014 patients were treated for elective aortic surgery. For 980 patients (96.6%), clear liquids followed by a semisolid diet were tolerated starting on the afternoon of the day of intervention (day 0). Nine hundred eighty-seven patients (97.3%) began early ambulation on day 0, and for 81.2% of the population, regular colonic function returned within the second postoperative day. Seventeen deaths (1.7%) occurred. Nine hundred ten patients (89.7%) had no complications. The median hospital length of stay was 3 days for the entire series, and 80.4% of patients (n = 815) were discharged to their homes between the second and fifth days after surgery. CONCLUSIONS The fast-track program can be efficiently and safely applied to aortic surgery and that this program improves surgical outcomes, allows for earlier discharge, and reduces costs.

Ruptured hemiarch and descending thoracic aorta aneurysm: hybrid treatment

Ruptured aortic arch aneurysm is a life threatening disease. Surgical repair has an high perioperative mortality rate and totally endovascular treatment is a challenge. Hybrid repair has been proposed as a valuable approach. We report the case of a patient with a contained rupture of aortic arch aneurysm. We treated him with a debranching of supraortic vessels with carotid-carotid and carotid-subclavian bypass and deployment of two enodgrafts in two different times. We consider hybrid treatment for arch and hemiarch a feasible option for aortic arch aneurysms in non emergent and in an emergency setting with an improvement in perioperative morbidity and mortality.

patients (23%) were clustered in group 1 and 47 (77%) in group 2. Both groups were homogeneous for clinical characteristics and preoperative morphological risk factors. There were no differences in preoperative median TV, THV, %VR, EgV, and number of implanted coils between groups. Patients in group 1 had a significantly wider EFV (59 6 13 cc vs 42 6 27 cc; P 1⁄4 .009) and lower CCoil (0.09 6 0.03 vs 0.18 6 0.21) than patients of group 2. ELIIp was significantly related to the presence of EFV >46 cc (86% group 1 vs 42% group 2; P 1⁄4 .006) and CCoil <0.17 coil/cc (100% group 1 vs 68% group 2; P 1⁄4 .014). Conclusions: AAA sac coil embolization is effective to reduce incidence of ELIIp in selected high-risk patients, and the CCoil may be considered to determine the necessary number of coils to obtain a complete AAA sac thrombosis.
