- In the Swedish vascular registry 7473 carotid endarterectomies are registered, in 10% the indication being a symptomatic stenosis. There are great variations in indication for carotid endarterectomy within Sweden. During the last five years the combined postoperative mortality and/or postoperative permanent stroke has varied between 3% in 1999 and 1.5% in 2003. During the same period not a single patient operated on for a symptomatic carotid stenosis experienced these complications.

Journal article (peer-reviewed)abstract
- Objective: The purpose of this multicentre study was to analyse the outcome of thoracic endovascular aortic repair (TEVAR) in patients with ruptured descending thoracic aortic aneurysm (rDTAA).Methods: This is a nationwide retrospective study including all patients who underwent TEVAR for rDTAA at six major vascular university centres in Sweden between January 2000 and December 2015. Outcome measures were analysed using Kaplan-Meier estimator and multivariable Cox regression.Results: There were 140 patients (age [mean +/- SD] 74.1 +/- 8.8 years; 56% men; aneurysm size 64.8 +/- 19 mm), with rDTAA. In 53 patients (37.9%), the left subclavian artery was covered, and in 25 patients (17.9%) arch vessel revascularisation was performed. In total, 61/136 patients (45%) had a major complication within 30 days post TEVAR. Stroke (n = 20; 14.7%) was the most common complication, followed by paraplegia (n = 13; 9.6%) and major bleeding (n = 13; 9.6%). TEVAR related complications during follow up included endoleaks 22.1% (30/136; 14 type 1a, six type 1b, 10 not defined). In total, re-interventions (n = 31) were required in 27/137 (19.7%) patients. The median follow up time was 17.0 months (range 0-132 months). The Kaplan-Meier estimated survival was 80.0% at one month, 71.7% at three months, 65.3% at one year, 45.9% at three years, and 31.9% at five years. Age (HR 1.03; 95% CI 1.00-1.07; p = .046), history of stroke (HR 2.35; 95% CI 1.194.63; p = .014), previous aortic surgery (HR 2.11; 95% CI 1.15-3.87; p = .016) as well as post-operative major bleeding (HR 4.40; 95% CI 2.20-8.81; p = .001), stroke (HR 2.63; 95% CI 1.37-5.03; p = .004), and renal failure (HR 8.25; 95% CI 2.69-25.35; p = .001) were all associated with mortality.Conclusions: This nationwide multicentre study of patients with rDTAA undergoing TEVAR showed acceptable short- but poor long-term survival. Adequate proximal and distal aortic sealing zones are important for technical success. High risk patients and post-operative complications need to be further addressed in an effort to improve outcome.

Cathepsin L is significantly associated with apoptosis and plaque destabilization in human atherosclerosis

Journal article (peer-reviewed)abstract
- Objective: Human atherosclerotic lesions overexpress elastolytic and collagenolytic cathepsins with unclear pathological implications. The aim of this study was to investigate the relationship among expression of cathepsin L. macrophage apoptosis in coronary artery disease (CAD) patients, clinical symptoms and plaque severity Of human carotid atheroma.Methods and results: Quantitative immunohistochemical analysis of human carotid atherosclerotic lesions (n = 49) showed that expression of lysosomal cathepsin L was significantly increased in atherosclerotic plaques with formation of the necrotic core and rupture of the cap. In those Plaques, cathepsin L was associated mainly with CD68-positive macrophages, whereas significant lower levels of smooth muscle cell actin were detected. The expression of cathepsin L in these plaques was also correlated with apoptosis and the stress protein ferritin. Plaques from symptomatic patients showed greater increased levels of cathepsin L than those front asymptomatic patients. Human monocyte-derived macrophages from CAD patients (n = 7) showed significantly higher levels of cathepsin L, cellular lipids and apoptosis versus cells from matched healthy donors (n = 7). 7Beta-hydroxycholesterol significantly enhanced cathepsin L in cells from healthy donors but not in Cells from CAD patients. Moreover. macrophage apoptosis was significantly correlated with expression of cathepsin L in cell nuclei and membranes.Conclusion: The results Suggest that cathepsin L is involved in death of macrophages necrotic Core formation and development of atherosclerotic plaque instability. Macrophage lysosomal cathepsin L and related apoptosis may be potential targets for modulation or imaging of vulnerable plaques in human atherosclerosis.
