BACKGROUND: The first-line recommendation for treatment of acute iliofemoral deep vein thrombosis (IFDVT) is catheter-directed or pharmaco-mechanical thrombolysis (CDT/PCDT). Recent analysis of surgical thrombectomy has shown comparable results. However this procedure is not commonly given as much importance as interventional techniques. We analyzed patient outcome of surgical thrombectomy using modern endovascular techniques in both the short and long term. METHODS: All consecutive patients who underwent surgical thrombectomy at our institution between April 2008 and April 2017 were included...

BACKGROUND: We present a case series of upper extremity fibromuscular dysplasia (UE FMD) consisting of 22 patients from two tertiary referral centers focusing on clinical presentation, diagnostic findings, and interventional outcomes. FMD is a noninflammatory, nonatherosclerotic arteriopathy that has a predisposition for middle-aged women. Involvement of the UE is thought to be rare. Patients with UE FMD can present with claudication or ischemia, or they can be incidentally diagnosed...

OBJECTIVES: The purpose was to analyze the agreement and binary accuracy of the degree of internal carotid artery stenosis (ICAS) as determined by 4-dimensionally (4D) real-time gray-scale guided 3-dimensional (3D) color-Doppler ultrasonography (3DC-US) (4D/3DC-US) compared with catheter angiography (CA) and duplex ultrasonography (DUS). This study hypothesized that 4D/3DC-US is noninferior to CA and DUS in grading ICAS in selected patients. BACKGROUND: Clinical stratification in patients with ICAS largely depends on a patient's symptomatic status and the degree of stenosis...

BACKGROUND Lienalis steal syndrome is a rare complication after orthotopic liver transplantation leading to severe complications. Routine duplex sonography allows early and safe detection of lienalis steal syndrome and secondarily helps to monitor the outcome by evaluating the hemodynamics. MATERIAL AND METHODS This analysis included eight patients who after orthotopic liver transplantation needed splenic artery embolization due to lienalis steal syndrome. Lienalis steal syndrome was assumed in case of elevated transaminases, bilirubinemia or persistent ascites, and the absence of further pathologies...

OBJECTIVE: Prior studies have suggested a relationship between operative (Op) time and outcome after major vascular procedures. This study analyzed factors associated with Op time and outcome after carotid endarterectomy (CEA) in the Vascular Quality Initiative (VQI) registry. METHODS: Elective, primary CEAs without high anatomic risk or concomitant procedures from 2012 to 2015 in the VQI were analyzed (N = 26,327, performed by 1188 surgeons from 249 centers). Multivariable analysis was used to identify patient, procedure, and surgeon factors associated with Op time and major adverse events (MAEs), categorized as either technical (ipsilateral stroke, cranial nerve injury, reoperation) or cardiac (myocardial infarction, congestive heart failure, dysrhythmia requiring treatment, surgical site infection, and death)...

Children are particularly at risk for stroke in the neonatal period. 1/3 of all strokes in children occur during the perinatal period. The incidence of perinatal stroke is 1:4000. A differentiation is made between ischemic stroke and hemorrhagic stroke. Ischemic strokes are caused by arterial occlusion due to thrombosis or embolism. As a result of the nonspecific clinical symptoms in this age group, diagnosis is usually made too late. The only relatively specific symptom is focal cerebral seizure during the first week of life...

OBJECTIVES: Endovenous thermal ablation (EVTA) of varicose veins was introduced in the late 1990s with radiofrequency ablation (RFA) using the VNUS Closure device. The results of the original VNUS Closure device for the abolition of truncal venous reflux at 15 years are reported. METHODS: A prospective audit of a group of patients treated with VNUS Closure 15 years previously was carried out, using clinical assessment and duplex ultrasound. A total of 189 patients were treated with VNUS Closure between March 1999 and December 2001 and were invited for clinical assessment (subjective and objective) and duplex ultrasonography (DUS) to assess treatment outcome and de novo disease progression...

BACKGROUND: Hepatic artery stenosis (HAS) after liver transplantation can progress to hepatic artery thrombosis (HAT) and a subsequent 30% to 50% risk of graft loss. Although endovascular treatment of severe HAS after liver transplantation has emerged as the dominant method of treatment, the potential risks of these interventions are poorly described. METHODS: A retrospective review of all endovascular interventions for HAS after liver transplantation between August 2009 and March 2016 was performed at a single institution, which has the largest volume of liver transplants in the United States...

BACKGROUND: Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is typically reported as a composite measure of the quality of trauma center care. Given recent data suggesting post-injury DVT and PE are distinct clinical processes, a better understanding may result from analyzing them as independent, competing events. Using competing risks analysis, we evaluated our hypothesis that the risk factors and timing of post-injury DVT and PE are different...

INTRODUCTION/OBJECTIVES: Nutcracker syndrome, caused by mesoaortic compression of the left renal vein leading to symptoms related to venous hypertension, is an uncommon entity that may require operative intervention. Traditional open transposition of the left renal vein to the vena cava has been shown to have a re-intervention rate of up to 30%, while also having additional morbidity associated with laparotomy. More recently, endovascular stenting has been described in several small series, but have reported stent fracture, thrombosis and migration...

REVIEW
C Stelzner, N Abolmaali, U Hecker, S Schellong
Visceral vessel processes are primarily or secondarily included in a multitude of clinical abdominal symptoms, with which the specialist in internal medicine is confronted. The spectrum ranges from more sharply outlined manifestations, such as chronic ischemic bowel disease up to dysfunctional disturbances of blood pressure regulation, such as high-grade renal artery stenosis. Sometimes diseases with prognostic implications, such as arterial aneurysms, are revealed as incidental findings. As a rule the B‑mode and duplex ultrasound can often be complemented by computed tomography (CT) and magnetic resonance imaging (MRI), as in aneurysms or portal vein thrombosis or the indications for subsequent digital subtraction angiography (DSA) and catheter-based therapy can be directly obtained from duplex and Doppler ultrasound...
