The Ongoing Challenge of Acute Mesenteric Ischemia.

Background: The lethality of acute mesenteric ischemia (AMI) remains quite high with 50-70%. The main reasons for that are the fact that AMI is rarely taken into consideration by the differential diagnosis of acute abdomen, the time-consuming diagnostic process, and the lack of a standardized therapeutic concept. The present interdisciplinary review aims to increase awareness among physicians and to help improve clinical outcomes.

Mortality in endovascular and open abdominal aneurysm repair - trends in Germany.

Background: We analysed trends in mortality of endovascular (EVAR) and open aortic repair (OAR) in patients hospitalized for abdominal aortic aneurysms (AAA) in Germany from 2005 to 2015.

Patients And Methods: We used national statistics published by the Federal Statistical Office in Germany to calculate mortality rate of patients hospitalized with ruptured (rAAA, n = 2,448 in 2005, n = 2,180 in 2015) and non-ruptured (iAAA, n = 11,626 in 2005, n = 14,205 in 2015) AAA.

Results: Considering only those who were treated with EVAR or OAR, treatment rates of iAAA with EVAR increased to 78.

Preservation of Endothelial and Smooth Muscle Function of Human Saphenous Vein Transplants.

Objectives: Methods for conservation and preservation of vascular grafts are often controversially discussed. Furthermore, immunologic monitoring or immunotherapy for allogeneic graft is not considered necessary in many cases. The present study was initiated to examine the cellular vitality and functional efficiency of vein transplant during preservation.

Very Long Segment Congenital Thoracoabdominal Aortic Coarctation (Diffuse Aortic Dysplasia) with Infrarenal Aortobi-Iliac and Cavobi-Iliac Aplasia in a 30-Year-Old Patient.

Congenital dysplastic aortic syndromes range from coarctation at the aortic isthmus to more extended aortic disease (midaortic syndrome). The latter is usually restricted to dysplastic aortic segments of up to 15 cm. Long segment dysplasia of the entire abdominal or thoracic aorta is extremely rare.

Percutaneous endovascular treatment of peripheral arterial disease in Germany.

Purpose: The general distribution of balloon angioplasty, stenting and other endovascular interventions in treating peripheral arterial disease (PAD) is unclear.

Methods And Results: We used national statistics (DRG statistics) published by the Federal Statistical Office including data from almost all hospitals in Germany to calculate the rates and types of lower extremity endovascular procedures in 2012. In 2012 150,503 peripheral endovascular procedures were documented in Germany.

Endovascular treatment of chronic mesenteric ischemia.

Purpose: Data regarding endovascular treatment of chronic mesenteric ischemia (CMI) are sparse. Angioplasty is often accompanied by early restenosis and the need of further interventions. Thus we present our own patients' data and review the recent literature.

Congenital subclavian steal syndrome with multiple cerebellar infarctions caused by an atypical circumflex retroesophageal right aortic arch with atretic aberrant left subclavian artery.

A right-sided aortic arch is a rare anomaly with an incidence of 0.1% worldwide and is usually associated with a mirror image of all supra-aortic branches or an aberrant left subclavian artery. The latter is often associated with a Kommerell diverticulum, although it can rarely be hypoplastic or atretic and lead to congenital subclavian steal.

CHADS and CHADSVasc-Score in Peripheral Systemic Embolism.

We analysed the characteristics of patients with an acute peripheral embolic event considering the possible use of the CHADS2-Score and the CHADSVasc-Score We retrospectively analyzed 163 cases of acute peripheral arterial embolism treated in the Department of Vascular Medicine of the HELIOS Klinik Krefeld, Germany, from 2008 to 2011. We retrospectively screened the medical form for information regarding atrail fibrillation (AF) and the risk factors necessary to calculate the CHADS and CHADSvasc score. Arterial hypertension and age > 75 years were the most frequent risk factors.

Decrease in major amputations in Germany.

A decrease in rate of amputation has been reported from many countries. This study aims to study the trends in amputation rates in Germany. On the basis of DRG-system, detailed lists of all amputations coded as minor amputations (OPS 5-864) and major amputations (OPS 5-865) performed between 2005 and 2010 were provided by the Federal Statistical Office.

Retrograde ascending Stanford B aortic dissection complicating a routine infrarenal endovascular aortic reconstruction.

Retrograde ascending aortic dissections usually complicate endovascular reconstructions of Stanford B dissections. Although rare, with an incidence of 1.3% to 6.

Acute mesenteric ischemia: a vascular emergency.

Background: Acute mesenteric ischemia is still fatal in 50% to 70% of cases. This consensus paper was written with the participation of physicians from all of the involved specialties for the purpose of improving outcomes. Mesenteric ischemia must be recognized as a vascular emergency requiring rapid and efficient clinical evaluation and treatment.

Influence of groin incision, duration of ischemia, and prostaglandin E1 on ischemia-reperfusion injury of the lower limb.

Objective: The influences of groin incision, duration of ischemia, and the effects of prostaglandin E1 (PGE1) on ischemia-reperfusion (I/R) injury of the hind limb in rabbits were evaluated.

Design: A prospective study.

Setting: Laboratory.

Management of arterial stenosis affecting kidney graft perfusion: a single-centre study in 53 patients.

We assessed clinical and duplex sonographic (CDS) findings, and outcome in patients with stenosis of the transplant renal artery (TRAS) or the aorto-iliac segment proximal to the graft (Prox-TRAS) treated with dilatation (PTA), stenting (PTAS) and surgery. From 1988 to 2002, of 1189 patients with renal transplantations, 117 underwent angiography. Fifty-three patients with TRAS (n = 37)/Prox-TRAS (n = 16) were found (4.

Primary malignant tumors of the aorta: clinical presentation, treatment, and course of different entities.

Objective: The objective of this study was to analyze possible correlations between the clinical presentation and the course of patients with different types of primary malignant aortic tumors.

Methods: A single academic center's experience was reviewed retrospectively.

Results: Four patients with primary malignant tumors of the aorta were treated in an 11-year period.

Deep venous thrombosis during pregnancy and after delivery: indications for and results of thrombectomy.

Purpose: Pregnancy and the puerperium are time periods of an increased risk for venous thromboembolism. An ideal treatment should lead to complete restoration of the venous lumen, elimination of the embolic source, and prevention of severe postphlebitic syndrome. Anticoagulation therapy with heparin or thrombectomy are treatment options.

Spontaneous rupture of collateral venous aneurysm in a patient with agenesis of the inferior vena cava: a case report.

We present a case of rupture of collateral venous vessels in the presence of agenesis of the inferior vena cava in a young woman. The embryologic development, pitfalls in diagnosis, and options for treatment in cases with agenesis of the inferior vena cava are discussed.
