Changes in job strain in relation to changes in physiological state. A longitudinal study

A sample of 73 men and women aged 22-63 years and working in six different occupations (air traffic controllers, waiters, physicians, symphony orchestra musicians, baggage handlers, and airplane mechanics) participated in a longitudinal study four times during a year. The spontaneous variations in job strain (determined as the self-reported ratio between psychological demands and decision latitude) were substantial. The average difference between the occasion with the highest level of strain and the occasion with the lowest level was 25% of the total mean. Systolic blood pressure during workhours, as well as self-reported sleep disturbance, increased when demands increased in relation to decision latitude. Among men with a depressive tendency (according to a diary) morning plasma prolactin levels increased markedly with increasing job strain. Among subjects with a positive family history of hypertension the increase in systolic blood pressure at work was particularly pronounced, and among the men in this group a lower than expected level of morning cortisol was found measured during the period with the highest level of strain.

Adenosine-to-inosine RNA editing controls cathepsin S expression in atherosclerosis by enabling HuR-mediated post-transcriptional regulation

Adenosine-to-inosine (A-to-I) RNA editing, which is catalyzed by a family of adenosine deaminase acting on RNA (ADAR) enzymes, is important in the epitranscriptomic regulation of RNA metabolism. However, the role of A-to-I RNA editing in vascular disease is unknown. Here we show that cathepsin S mRNA (CTSS), which encodes a cysteine protease associated with angiogenesis and atherosclerosis, is highly edited in human endothelial cells. The 3' untranslated region (3' UTR) of the CTSS transcript contains two inverted repeats, the AluJo and AluSx⁺ regions, which form a long stem-loop structure that is recognized by ADAR1 as a substrate for editing. RNA editing enables the recruitment of the stabilizing RNA-binding protein human antigen R (HuR; encoded by ELAVL1) to the 3' UTR of the CTSS transcript, thereby controlling CTSS mRNA stability and expression. In endothelial cells, ADAR1 overexpression or treatment of cells with hypoxia or with the inflammatory cytokines interferon-γ and tumor-necrosis-factor-α induces CTSS RNA editing and consequently increases cathepsin S expression. ADAR1 levels and the extent of CTSS RNA editing are associated with changes in cathepsin S levels in patients with atherosclerotic vascular diseases, including subclinical atherosclerosis, coronary artery disease, aortic aneurysms and advanced carotid atherosclerotic disease. These results reveal a previously unrecognized role of RNA editing in gene expression in human atherosclerotic vascular diseases.

Social support, job strain and musculoskeletal pain among female health care personnel

OBJECTIVES

This study explored the relationship between psychosocial work environment and the musculoskeletal pain among health care personnel.

MATERIALS AND METHODS

Ninety registered nurses and nurse's aides working in different hospitals in or just outside Stockholm and working in different kinds of care constituted the study group. Data were collected by means of questionnaires, including questions about symptoms (low-back pain, pain in the neck, and pain in the shoulders), the perception of social support from co-workers and superiors, conflicts, feelings of isolation, poor relations with superiors, psychological demands, authority over decisions, and skill utilization (job-strain factors).

RESULTS

An ordinal univariate logistic regression analysis showed that psychological demands, authority over decisions, skill utilization, and support at work had a statistically significant effect on symptoms from the lower back, while symptoms from the neck and shoulders were related to support a work only. When support at work and job strain were entered into a multivariate logistic regression model, a difference in the patterns of associations between low-back pain and symptoms from the neck and shoulders was found. Symptoms from the back were significantly related to job strain--the higher the strain, the more symptoms in the low back. Symptoms from the neck and shoulders on the other hand were more associated with social support at work--the lower the support score the more severe the symptoms.

CONCLUSIONS

Low-back pain seemed to be related to job strain, while symptoms from the neck and shoulders were to a greater extent related to relational and emotional factors.

Influence of job strain and emotion on blood pressure in female hospital personnel during workhours

A homogeneous sample of 56 women who were between the ages of 20 and 59 years and worked in acute emergency care, child psychiatry, or a pediatric outpatient clinic comprised the subjects of this study to determine the relationship between job strain and blood pressure. Job strain was measured with a standardized questionnaire, and blood pressure during workhours with self-triggered equipment. Endocrine factors (morning concentration of plasma prolactin, cortisol, and dehydroepiandrosterone) and emotional states recorded in diaries were also studied. Significant interrelationships occurred among perceived job strain, plasma prolactin, and diastolic blood pressure during workhours even when body mass index, age, family history of hypertension, level of education, and mood state were adjusted for in a multiple regression analysis. Thus job strain of female care givers was associated with systolic and diastolic blood pressure during workhours and also with diastolic blood pressure at rest, but not with blood pressure during leisure time.

Transluminal angioplasty of isolated crural arterial lesions in diabetics with critical limb ischemia

Background: We investigated the long-term clinical results of transluminal angioplasty of isolated infrapopliteal arteries in diabetic patients with severe ischaemic foot lesions and the influence of different parameters on primary success, the long-term outcome and the survival rate. Patients and methods: Between January 2001 and May 2004 we performed 50 transluminal angioplasties in 52 (10 female, 42 male, mean age 69.3 years) diabetics with isolated lesions of crural arteries (tibio-peroneal trunk 41, anterior tibial 13, posterior tibial 5, peroneal artery 14) and limb threatening ischaemia (rest pain 12, tissue loss 40). In two patients the dilatation could not be performed due to vessel perforation and impossibility to catheter localization. The morphological classification of infrapopliteal lesions was determined according to guidelines provided by TransAtlantic Inter-Society Consensus (TASC) (17 type A, 16 type B, 13 type C, 4 type D). Results: Initial technical success after angioplasty of crural arteries could be obtained in 96%.Kaplan-Meier analysis showed a cumulative limb salvage of 92%,85% and 68, 9% after 6 months,one and two years, respectively. Patients falling in TASC group C had significantly higher risk of amputation. Overall survival at 1 year was calculated at 85% and at 2 years at 65%. Conclusion: Our results suggest that depending on the extent of lesions transluminal angioplasty of infrapopliteal artery stenoses and occlusions is considered as an effective and save therapy modality to avoid limb loss in diabetics with critical ischemia.

Circulating levels of TNF-like cytokine 1A correlate with the progression of atheromatous lesions in patients with rheumatoid arthritis

Interactions between TNF-like Cytokine 1A (TL1A) and its receptors, death receptor-3 (DR3) and decoy receptor-3 (DcR3) may be important in atherogenesis. We hypothesized that dysregulation of this system predicts formation of new atheromatic plaques in rheumatoid arthritis (RA). Forty-five patients were prospectively followed up for 40.5 ± 3.6 months. Serum concentrations of TL1A and DcR3 were measured at baseline and carotid and femoral arteries examined by ultrasound at baseline and at the end of follow-up. Individual serum levels of TL1A correlated with the progression of carotid atheromatic plaque height (Spearman rho = 0.550, p = 0.003). Patients with low TL1A and undetectable DcR3 serum levels at baseline showed significantly fewer newly formed carotid plaques during the next 3.5 years than the remaining patients (P = 0.016). Univariate analysis showed that a "low TL1A/DcR3" immunophenotype predicted a preserved atherosclerosis profile in carotid (P = 0.026), or carotid and/or femoral arteries (P = 0.022). Dysregulated TL1A-induced signaling may be associated with risk for accelerated atherosclerosis in RA.

Heregulin, cysteine rich-61 and matrix metalloproteinase 9 expression in human carotid atherosclerotic plaques: relationship with clinical data

OBJECTIVES

Heregulins (HRGs) are known to induce expression of angiogenic factors such as cysteine rich-61 (CYR61) and collectively to promote neoangiogenesis. Along with extracellular matrix remodelling, mediated by matrix metalloproteinases (MMPs), these factors are important in atherogenesis. The aim of the present study was to investigate HRG, CYR61 and MMP-9 expression and their relationship with clinical and histopathological findings in carotid occlusive disease.

MATERIALS AND METHODS

Specimens of human carotid atherosclerotic plaque (n=90) were obtained by endarterectomy. Expression of HRG, CYR61 and MMP-9 was assessed by immunohistochemical and Western blot analysis. Associations between protein expression and degree of carotid stenosis, presence of symptoms, presence of an infarct in CT scan and carotid plaque histopathology were investigated.

RESULTS

An increase in HRG, CYR61 and MMP-9 expression was found, particularly in neovascularized regions of the plaques. High HRG expression was associated with the degree of carotid stenosis (p=0.028) and plaque histopathology (p=0.002). More than half of specimens from plaques with >90% stenosis had intense expression of CYR61 (p=0.047). Increased expression of MMP-9 was associated with degree of stenosis and presence of cerebral infarct on CT scan (p=0.05).

CONCLUSION

HRG, CYR61 and MMP-9 are highly expressed in human atherosclerotic carotid plaques. The association with the degree of stenosis and/or plaque histopathology implies an involvement in lesion progression.

Acute limb ischemia among patients with COVID-19 infection

OBJECTIVE/BACKGROUND

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been associated with thrombotic complications such as deep vein thrombosis or stroke. Recently, numerous cases of acute limb ischemia (ALI) have been reported although pooled data are lacking.

METHODS

We systematically searched PubMed, Embase, Scopus, and the Cochrane Library for studies published online up to January 2021 that reported cases with SARS-CoV-2 infection and ALI. Eligible studies should have reported early outcomes including mortality. Primary endpoints included also pooled amputation, clinical improvement, and reoperation rates.

RESULTS

In total, 34 studies (19 case reports and 15 case series/cohort studies) including a total of 540 patients (199 patients were eligible for analysis) were evaluated. All studies were published in 2020. Mean age of patients was 61.6 years (range, 39-84 years; data from 32 studies) and 78.4% of patients were of male gender (data from 32 studies). There was a low incidence of comorbidities: arterial hypertension, 49% (29 studies); diabetes mellitus, 29.6% (29 studies); dyslipidemia, 20.5% (27 studies); chronic obstructive pulmonary disease, 8.5% (26 studies); coronary disease, 8.3% (26 studies); and chronic renal disease, 7.6% (28 studies). Medical treatment was selected as first-line treatment for 41.8% of cases. Pooled mortality rate among 34 studies reached 31.4% (95% confidence interval [CI], 25.4%%-37.7%). Pooled amputation rate among 34 studies reached 23.2% (95% CI, 17.3%-29.7%). Pooled clinical improvement rate among 28 studies reached 66.6% (95% CI, 55.4%%-76.9%). Pooled reoperation rate among 29 studies reached 10.5% (95% CI, 5.7%%-16.7%). Medical treatment was associated with a higher death risk compared with any intervention (odds ratio, 4.04; 95% CI, 1.075-15.197; P = .045) although amputation risk was not different between the two strategies (odds ratio, 0.977; 95% CI, 0.070-13.600; P = .986) (data from 31 studies).

CONCLUSIONS

SARS-CoV-2 infection is associated with a high risk for thrombotic complications, including ALI. COVID-associated ALI presents in patients with a low incidence of comorbidities, and it is associated with a high mortality and amputation risk. Conservative treatment seems to have a higher mortality risk compared with any intervention, although amputation risk is similar.

Outcome of infrainguinal revascularization for critical limb ischemia in diabetics with end stage renal disease

Background: End stage renal disease [ESRD] and diabetes have a negative effect on outcome of arterial reconstructions, because they are associated with a vulnerability to infection, an infrageniculate arterial occlusive disease and an increased perioperative risk. The combination of both in critically ischemic patients is traditionally considered a great threat to their limb or life. The risk/benefit ratio of revascularization in this clinical setting is marginal and therefore the decision making is controversial. This study was undertaken to determine the results of arterial reconstruction in patients with end-stage renal disease and diabetes mellitus. Patients and methods: The outcome of 97 patients undergoing 121 arterial reconstructions due to lower limb threatening ischemia were reviewed. Primary and secondary patency rates as well as survival and limb salvage were estimated. Results: Thirty-day operative mortality rate was 10.3%. At one month, one year and 2 year follow-up, the survival rate was 89.7%, 77.6% and 44.2% respectively. Limb salvage at 6 months was 85.6%, at 12 months 75.3% and at 2 years 56.3%. The primary and secondary patency was 92.4% and 93.2% at 6 months and 71.7% and 72.7% at 12 months, respectively. Conclusions: Diabetic patients with ESRD attained an acceptable graft patency and limb salvage but they sustained higher perioperative mortality and morbidity and reduced survival.

Relationship between iNOS expression and aortic cell proliferation and apoptosis in an elastase-induced model of aorta aneurysm and the effect of 1400 W administration

BACKGROUND

In the present study, we employed an elastase infusion-dependent abdominal aortic aneurysm (AAA) model to examine inducible nitric oxide synthase (iNOS) expression in relation to cellular proliferation and apoptosis in this pathologic condition. Furthermore, we employed N-(3-(aminomethyl)benzyl)acetamidine (1400 W), a previously shown selective iNOS inhibitor, to further explore this relationship.

METHODS

Adult male Wistar rats were randomized into separate groups. Group A served as a control and received an intra-aortic saline infusion, while groups B, C, and D received an intra-aortic elastase infusion according to standard protocols. The animals in group C were administered postoperatively the highly selective iNOS inhibitor, 1400 W, while rats in group D received regularly the same compound preoperatively and postoperatively. The animals were killed at postoperative days 7 and 14. Aorta diameter and nitric oxide (NO), nitrite/nitrate, and MDA levels were measured. iNOS expression was assessed by immunohistochemistry and Western blot analysis, while Ki-67 immunohistochemistry and TUNEL assay were used to evaluate cellular proliferation and apoptosis, respectively.

RESULTS

Increased iNOS and NO levels accompanied aneurysm development in groups B, C, and D, but these levels were significantly lower in groups C and D, compared with group B. Interestingly, very low but detectable levels of iNOS were found in the control group, indicating a basal constitutive level. Cell growth parameters were augmented in group B compared with group A. In contrast, groups C and D exhibited a significant decrease of the cellular growth parameters but did not attain normal values.

CONCLUSIONS

iNOS-derived NO is associated with the cellular growth parameters of the vessel cells, predominantly smooth muscle cells. Selective iNOS blockage ameliorates the cellular remodeling in AAAs.

Highly Conserved Sequence of Exon 15 BRAF Gene and KRAS Codon 12 Mutation among Greek Patients with Colorectal Cancer

Background

The RAS/RAF/MEK/MAP kinase pathway is essential to intracellular signaling transduction regulating cell proliferation, differentiation and death. We investigated the occurrence of exon 15 BRAF and KRAS codon 12 mutations among Greek patients with colorectal cancer.

Methods

Sixty-one samples from patients with sporadic colorectal adenocarcinomas were studied for exon 15 BRAF mutations. DNA from surgically resected specimens was analyzed by a combination of polymerase chain reaction and direct sequencing. KRAS codon 12 mutational analysis was technically possible in 58 samples (58/61) by a combination of polymerase chain reaction and restriction fragment length polymorphism.

Results

No exon 15 BRAF mutations were detected in any of the colon cancer specimens. The frequency of KRAS codon 12 mutations was 29.3% (17/58). Patients aged <70 years more frequently presented carcinomas harboring KRAS codon 12 mutations than patients aged >70 years (p=0.028). Patients between 61 and 70 years of age were more likely to be carriers of this mutation (p=0.040).

Conclusions

Despite the limited study sample, our data suggest that BRAF mutations might be present less frequently than KRAS mutations in Greek patients with colorectal carcinomas. Further research involving larger patient series will be necessary to confirm these findings and to assess possible ethnic, environmental and lifestyle influences on BRAF and KRAS mutagenesis.

Vascular endothelial cadherin expression in human carotid atherosclerotic plaque and its relationship with plaque morphology and clinical data

OBJECTIVES

To determine the relationship between Vascular Endothelial (VE)-cadherin expression in carotid plaques, carotid plaque morphology and clinical findings of carotid disease.

MATERIALS AND METHODS

Fifty-three formalin-fixed, paraffin embedded specimens of human carotid atherosclerotic plaque obtained by endarterectomy and 20 normal postmortem arteries (control group) were studied. Thirty patients were symptomatic and 23 asymptomatic. The expression of VE-cadherin was examined by an avidin-biotin immunoperoxidase technique using specific monoclonal antibodies against this molecule. We used a scale for the estimation of the expression of the VE-cadherin, in which negative expression was indicated by 0, weak expression by 1, and strong expression by 2. In serial sections we also determined the cellular phenotype of atherosclerotic plaques: i.e. the endothelial cells (F8), macrophage (CD68) and smooth muscle cells. Possible relations between variables in statistical analysis were examined by the chi-square test or Fisher's exact test.

RESULTS

Expression of VE-cadherin was observed in small newly established vessels, particularly in areas with intense inflammatory infiltrations by macrophages and leucocytes. A strong expression of VE-cadherin was evident particularly in symptomatic instead in asymptomatic patients (43% vs. 13%, p=0.057), in high degree stenosis group (81% vs. 0%, p=0.005), and in patients with ischaemic infarct in brain scan (71% vs. 23%, p=0.021). On the other hand, there was no relation between molecule expression and plaque ultrasonic characteristics (echogenic or echolucent, p=0.499). Finally, there was a significant statistical correlation in the expression of VE-cadherin and the histological type of the plaque, namely fibrotic and complicated plaques. Strong VE-cadherin expression was observed in 64% of complicated plaques instead of 6.5% in fibrotic plaques (p=0.001).

CONCLUSION

An intense expression of VE-cadherin in carotid plaques is linked with plaque instability, high degree of stenosis and clinical events. This molecule seems to be a marker of progression of the atherosclerotic plaque.

Absence of association with cancer risk and low frequency of alterations at a p53 responsive PIG3 gene polymorphism in breast and lung carcinomas

The mechanisms of p53-dependent apoptosis involve a set of genes that possess the ability to modulate oxidative stress. One of them PIG3, is induced by p53 through a microsatellite in its promoter region. This microsatellite was found to acquire its full structure and p53-functional dependence only in Hominoidea (apes and humans) and has been proposed to represent an evolutionary adaptation of tumor suppressor mechanisms. Microsatellite instability and genetic constitution, comprising the presence of the low repetition allele (10 TGYCC repeats), at this locus have been hypothesized to provide an increased risk for cancer development. Therefore, in the present analysis we examined this polymorphism in two common human cancers, lung and breast and compared it with corresponding control cases. Furthermore, for lung cancer we employed two different ethnic groups, Greek and British. Analysis of this locus in this types of tumors showed: (1) a very low frequency of microsatellite instability and loss of heterozygosity (1.4% and 4%, respectively) in the examined carcinomas, (2) the homozygous presence of the 10 repeats allele only in the control cases, and (3) a non-significant increase of the most frequent allele (15 repeats) in the cancer groups as compared to control ones. The last two observations were found in both Greek and British populations. Taken together, these data do not support the notion that this PIG3 polymorphism is associated with an increased risk for cancer susceptibility. Larger studies including other types of cancer should also be performed.

Radiofrequency tissue ablation in an experimental model of grade IV renal trauma: a preliminary report

BACKGROUND

The kidney is one of the most frequently injured intraabdominal organs. In this study, we investigated the efficacy and safety of radiofrequency ablation (RFA) as a kidney-preserving hemostatic technique for grade IV renal trauma.

METHODS

A grade IV injury was induced in the right kidney of 12 Landrace pigs. Then RFA was applied around the injury in 10 animals until hemostasis was achieved; two animals were not treated (control group). The treated animals were killed humanely on days 0, 3, 7, 14 and 21 and examined. The kidneys were subjected to histologic and radiologic examination.

RESULTS

The two untreated animals died from hypovolemic shock. Hemostasis was achieved in all treated animals. We had no operative deaths and no morbidity. No blood, pus, urine, or other fluid was found at the time of death. In one animal, a fistulous lesion leading to the collecting system was identified, but no urine leakage was observed. At histology, the ablated areas were found to consist of three zones: an inner necrotic one, a zone of neutrophils digesting necrotic tissue, and an outer zone with possibly reversible damage.

CONCLUSIONS

Radiofrequency ablation is an efficient and safe hemostatic method for grade IV renal trauma. Further study is needed to investigate the possible application of this method to humans and its percutaneous or laparoscopic use.

Right subclavian double steal syndrome: a case report

Introduction

Double-steal syndrome represents a causative factor for blood flow compromise of the cerebral vascular bed with transient neurologic symptoms. We present the case of a patient with innominate artery atherosclerotic occlusion, manifested as blood flow reversal in the vertebral and common carotid arteries. Symptomatic atherosclerotic occlusive disease of the innominate artery is relatively rare and represents less than 2% of all extracranial causes of cerebrovascular insufficiency.

Case presentation

We report on a 73-year-old male patient who presented at our hospital for the evaluation of dizziness and episodes of syncope. Angiography and color Doppler examinations documented the double syndrome as retrograde flow in the right vertebral artery and the right carotid artery.

Conclusion

Constituting an indication for surgical correction, his condition was managed with the performance of carotid-carotid extra-anatomic bypass for the permanent reestablishment of antegrade blood flow in the vascular network supplying the brain. Carotid-carotid extra-anatomic bypass was a good option for our patient, since he remains symptom free after one year of follow up.

Retroperitoneal perforation of a duodenal diverticulum with colonic necrosis -- report of a case

Primary duodenal diverticula are usually asymptomatic. About 115 perforations have been reported, but none with right colon necrosis. We report a 45-year-old woman, with a five days history of high fever along with epigastric and periumbilical pain. Physical examination revealed right upper and lower quadrant tenderness with peritoneal signs. White blood cell count was 11 500/mm (3) while biochemical and hepatic biology tests were normal. Abdominal radiographs showed no pathologic findings. Ultrasound disclosed fluid in the lower pelvis. Computerized tomography revealed fluid collection in the right hepatorenal space. Intraoperative findings included purulent fluid in the lower pelvis, segmental necrotic changes of the right colon, and a perforated diverticulum on the antimesenteric border of the third part of the duodenum. Surgery consisted of right hemicolectomy and ileo-transverse anastomosis, diverticulectomy, and decompressive lateral duodenostomy at the second duodenal portion. The patient had an uneventful postoperative course. A contrast study from the duodenostomy tube on the 6 (th) postoperative day showed no leakage or obstruction. Duodenostomy tube was removed on the 14 (th) postoperative day. Histology confirmed the diagnosis of a primary duodenal diverticulum.

Late Sac Rupture due to a Type IV Endoleak after Previous Endovascular Aortic Aneurysm Repair: A Case Report

Type IV endoleaks have been identified as endoleaks of low flow, and rupture risk has been estimated to be minimal in literature. Therefore, conservative treatment has been recommended in most cases. We are presenting a rare case of late rupture due to type IV endoleak that was treated with open repair applying a novel surgical technique.

Presternal gastric bypass for late postpneumonectomy esophagopleural fistula

A 71-year-old diabetic patient underwent right pneumonectomy with wide mediastinal lymph node dissection for lung cancer (right upper lobe). Postoperatively he developed pleura empyema that was successfully treated - drainage and Eloesser window, followed by adjuvant radiotherapy. Two months later he developed an esophagopleural fistula. Due to the patient's physical condition primary repair of the esophageal rupture was considered a high-risk operation. Stenting was also considered as inappropriate due to the existing contamination. Bypassing with the use of the stomach as conduit was preferred due to its simplicity compared to the colon. In order to avoid mediastinum after the postradiation alterations and because of the Eloesser window we adopted a presternal subcutaneous position. Twenty-eight months after the by pass procedure the patient is in good health being able to eat and drink, has gained weight and shows no evidence of malignancy. Presternal gastric esophageal bypass has never been reported as a treatment for esophagopleural fistula. This case report indicates its possible successful use in this debilitating setting, although more experience is needed.

Management of massive presacral bleeding during low pelvic surgery -- an alternative technique

Although massive presacral bleeding during rectal mobilization is uncommon, it can rapidly destabilize a patient. So, effective hemostasis is critical in severe presacral hemorrhage due to the fatal course of this complication. Among the reported methods are packing, thumbtacks, inflatable devices, muscle tamponade, muscle fragment welding and application of endoscopic staplers. Local hemostatic agents in conjunction with other methods such as diathermy, cyanoacrylate tissue adhesives and application of bone wax are among other alternatives which may help to treat this serious complication. The aim of this study is to describe the anatomic and physiologic basis of our mode of treatment, which is new in the literature approach, treating two patients with presacral bleeding during low anterior resection for rectal cancer. The technique is the early clamping of the infrarenal aorta and suture ligation of the bleeding points from the presacral plexus.

New paradigms in minimally-invasive vascular surgery

INTRODUCTION

Vascular surgery has been greatly evolved during the last decades and novel minimally invasive techniques have been introduced. Aim of this review is to briefly present all these advances and compare them with traditional repairs.

AREAS COVERED

The authors have extensively searched literature through the Pubmed and Embase databases. All articles published up to December 2021 referring to minimally invasive techniques used for treatment of peripheral artery disease, carotid disease, aortic aneurysms and venous disease were evaluated. Minimally invasive techniques under investigation included endovascular and hybrid techniques, robot-assisted and laparoscopic approaches.

EXPERT OPINION

Several minimally invasive techniques such as endovascular and hybrid approaches have been extensively used during the last two decades to treat vascular surgery patients offering them lower mortality and morbidity risks. Novel robot assisted techniques have shown promising results in preclinical studies although further clinical evaluation is needed.
