Critical chronic ischemia in patients with underlying arterial occlusive disease requires vascular reconstructive surgery. The limited supply of suitable small-diameter autologous vascular grafts in many patients and obvious disadvantages of synthetic bypass material demand the development of clinically usable tissue-engineered blood vessel substitutes. Despite substantial progress in the field over the last two decades, their implementation into the clinical routine has been challenging. The limited replicative life span of human adult vascular cells and their slow rate of collagenous matrix production in vitro have posed important problems in the development of mechanically robust and biologically functional engineered grafts...

Background: The complex endovascular repair of aortic aneurysms and dissections with fenestrated or branched stent grafts (FB-EVAR) remains challenging for interventional vascular surgery. To date, the evidence regarding treatment patterns and outcome measures consists of single center studies; however, it might be reasonable to validate results with multicenter real-world evidence. Methods: Health insurance claims data from Germany's third largest insurance provider, DAK-Gesundheit, were used to determine outcomes following FB-EVAR of non-ruptured thoracic aorta (TA) or thoracoabdominal including pararenal abdominal (TAA) aorta...

Background: Abdominal aortic aneurysms (AAA) have most probably an inflammatory origin, whereby the elastica is the layer actually involved. In the past, collagen weackness was supposed to be the shared cause of both, AAA and incisional hernias. Since the development of new techniques of closure of the abdominal wall over the last decade, collagen deficency seems to play only a secondary etiologic role. Objectives: The aim of the study was to investigate whether the incidence of incisional hernia following laparotomy due to AAA differs from that of colorectal interventions...

Visceral artery aneurysms are rare with an incidence of only 0.01-0.1% of the population. Open surgical or endovascular elimination should be performed for aneurysms greater than 2 cm in size. The risk of aneurysm rupture is then approximately 25-40%. If the aneurysm ruptures the mortality can be as high as 76%. For mycotic aneurysms or spurious aneurysms there is no lower limit to the diameter size for the need of treatment. Sudden abdominal pain during pregnancy can be caused by visceral artery aneurysms and must be further clarified...

Chronic ischemia of the lower extremities is an everyday problem in vascular surgery clinics. In Germany, approximately 3% of all hospitalizations are due to peripheral artery disease (PAD), with critical limb ischemia (CLI) in particular showing a rapid increase. The consequences of chronic undersupply range from reduced walking distance to loss of limbs. At the beginning there are stress factors, such as hyperlipidemia (LDL), free radicals, arterial hypertension, infections or subclinical inflammation that interfere with endothelial homeostasis and cause endothelial dysfunction with increased permeability...

REVIEW
U Rother, W Lang
Critical limb ischemia (CLI) remains a challenge for an interdisciplinary therapeutic team due to chronic nonhealing wounds. Against this background, there is a necessity of quality control after revascularization. Beside the isolated evaluation of the macrocirculation by Ankle-Brachial or Toe-Brachial Index measurements, the microcirculation as an additional important factor of wound healing often remains underestimated. The following article gives an overview about the current investigation methods for noninvasive perfusion control of the CLI patient...

This article summarizes the current study situation on treatment of asymptomatic carotid artery stenosis and discusses the evidence situation in the literature. The 10-year results of the ACST study have shown that in comparison to conservative treatment, carotid endarterectomy (CEA) has retained a positive long-term effect on the reduction of all forms of stroke. All multicenter randomized controlled trials comparing CEA with carotid artery stenting (CAS) and, in particular the SAPHIRE and CAVATAS studies, have in common that despite a basic evidence level of Ib, the case numbers of asymptomatic patients are too small for a conclusive therapy recommendation...

Endovascular treatment of thoracic and thoracoabdominal aortic diseases is accompanied by a risk of spinal ischemia in 1-19% of patients, depending on the entity and extent of the disease. The use of perioperative drainage of cerebrospinal fluid is one of the invasive measures to reduce the occurrence of this severe complication. This article reviews the incidence of spinal ischemia, its risk factors, the evidence for carrying out cerebrospinal fluid drainage and its modern use by means of an automated, pressure controlled system (LiquoGuard®7)...

BACKGROUND: Guidelines summarize medical evidence, they identify the most efficient therapy under study conditions and recommend this therapy for use. The physician now has the challenge to translate a therapy that is efficient under laboratory conditions to a patient who is an individual person. To accomplish this task the physician has to make sure that (I) the ideal typical therapy is applicable and effective in this individual patient taking the special features into consideration, that (II) therapy is compliant with the norm including guidelines, laws and ethical requirements (conformity) and that (III) the therapy meets the patient's needs...

The pathogenesis of venous thromboembolism (VTE) is still not completely understood. Experimental animals in which human deep vein thrombosis can be modeled are useful tools to investigate the pathogenesis of VTE. Besides the availability of transgenic and genetically modified mice, the use of high frequency ultrasound and intravital microscopy plays an important role in identifying thrombotic processes in mouse models. In this article, an overview about the application of various new technologies and existing mouse models is provided, and the impact of venous side branches on deep vein thrombosis in the mouse model is discussed...

BACKGROUND: The most important structural proteins of the vascular wall are collagen and elastin. Genetically linked connective tissue diseases lead to degeneration, aneurysm formation and spontaneous dissection or rupture of arteries. The most well-known are Marfan syndrome, vascular Ehlers-Danlos syndrome (type IV), Loeys-Dietz syndrome and familial aortic aneurysms and dissections. OBJECTIVE: This review article addresses the current status of endovascular treatment options for important connective tissue diseases...

BACKGROUND: Intermittent claudication (IC) is a common condition that causes pain in the lower limbs when walking and has been shown to severely impact the quality of life (QoL) of patients. The QoL is therefore often regarded as an important measure in clinical trials investigating intermittent claudication. To date, no consensus exits on the type of life questionnaire to be used. This review aims to examine the QoL questionnaires used in trials investigating peripheral arterial disease (PAD)...

Infectious aortitis is a rare but life-threatening disease. Due to impending local and systemic complications, prompt diagnosis and initiation of effective causal treatment are essential for patient survival. Differentiating infectious aortitis from other aortic diseases, in particular non-infectious aortitis, is of great importance. This article discusses the various causes, diagnostic tools, and therapeutic strategies for infectious aortitis.

REVIEW
I Töpel, N Zorger, M Steinbauer
Aortitis is a term which encompasses inflammatory changes to the aortic wall from various pathogenic etiologies. Large vessel vasculitis, such as Takayasu arteritis and giant cell arteritis represent the most common entities; however, there is also an association with other rheumatological diseases. Chronic idiopathic periaortitis represents a distinct disease entity and infectious aortitis is a rare but life-threatening disease. Due to the diverse clinical pictures vascular surgeons often face a significant challenge in terms of making an accurate initial diagnosis...

BACKGROUND: In general, autologous veins are the optimal replacement material for an infected vascular graft in terms of handling, durability and resistance to reinfection. In the absence of suitable autologous material, several options are available, each of which has specific advantages and drawbacks with regard to these characteristics. METHODS: In recent years, xenogeneic materials (in particular pericardial patches from different species and biosynthetic grafts) have been increasingly used as replacement material in the setting of infections...

BACKGROUND: The use of autologous superficial femoral veins (SFV) as an arterial or venous substitute represents a valuable technique in modern vascular surgery with versatile indications. The SFV autografts exhibit excellent control of infection and durable long-term results in terms of graft patency in prosthetic or arterial infections. In cases of elective use of the SFV, duplex ultrasound evaluation of the deep leg vein system should be implemented to confirm the patency of the profunda femoris vein...
