Objective: The new 2019 guideline of the European Society for Vascular Surgery (ESVS) recommends consideration for elective iliac artery aneurysm (eIAA) repair when the iliac diameter exceeds 3.5 cm, as opposed to 3.0 cm previously.

Toward Optimizing Risk Adjustment in the Dutch Surgical Aneurysm Audit.

Background: To compare hospital outcomes of aortic aneurysm surgery, casemix correction for preoperative variables is essential. Most of these variables can be deduced from mortality risk prediction models. Our aim was to identify the optimal set of preoperative variables associated with mortality to establish a relevant and efficient casemix model.

A Comparative Cost-Effectiveness Analysis of Percutaneous Transluminal Angioplasty With Optional Stenting and Femoropopliteal Bypass Surgery for Medium-Length TASC II B and C Femoropopliteal Lesions.

Purpose: To evaluate the total midterm costs and cost-effectiveness of percutaneous transluminal angioplasty with optional stenting (PTA/S) as initial treatment compared with femoropopliteal bypass (FPB) surgery in patients with medium-length TransAtlantic Inter-Society Consensus II (TASC) B and C femoropopliteal lesions.

Materials And Methods: Over a period of 3 years, all hospital health care costs for 226 consecutive patients were calculated: 170 patients with a TASC B lesion and 56 patients with a TASC C lesion. In the 135-patient PTA/S group (mean age 69.

Long-Term Clinical Outcomes of Percutaneous Transluminal Angioplasty with Optional Stenting in Patients with Superficial Femoral Artery Disease: A Retrospective, Observational Analysis.

Background And Objective: The recent ESC guideline advises primary stent placement in superficial femoral arterial disease (SFAD). The aim of this study was to compare clinical outcomes of SFAD patients selected for stent placement with plain percutaneous transluminal angioplasty (PTA).

Materials And Methods: A single centre retrospective, observational analysis was performed of all consecutive patients undergoing endovascular treatment for SFAD from 2004 to 2015.

The use of thoracic stent grafts for endovascular repair of abdominal aortic aneurysms.

Objectives Stent grafts for endovascular repair of infrarenal aneurysms are commercially available for aortic necks up to 32 mm in diameter. The aim of this study was to evaluate the feasibility of endovascular repair with large thoracic stent grafts in the infrarenal position to obtain adequate proximal seal in wider necks. Methods All patients who underwent endovascular aneurysm repair using thoracic stent grafts with diameters greater than 36 mm between 2012 and 2016 were included.

Cost-Effectiveness of Two Decision Strategies for Shunt Use During Carotid Endarterectomy.

Background: Arterial shunting during carotid endarterectomy (CEA) is essential in some patients because of insufficient cerebral perfusion during cross-clamping. However, the optimal diagnostic modality identifying these patients is still debated. None of the currently used modalities has been proved superior to another.

Systematic review of mortality risk prediction models in the era of endovascular abdominal aortic aneurysm surgery.

Background: The introduction of endovascular aneurysm repair (EVAR) has reduced perioperative mortality after abdominal aortic aneurysm (AAA) surgery. The objective of this systematic review was to assess existing mortality risk prediction models, and identify which are most useful for patients undergoing AAA repair by either EVAR or open surgical repair.

Methods: A systematic search of the literature was conducted for perioperative mortality risk prediction models for patients with AAA published since 2006.

Adjusted Hospital Outcomes of Abdominal Aortic Aneurysm Surgery Reported in the Dutch Surgical Aneurysm Audit.

Objective/background: The Dutch Surgical Aneurysm Audit (DSAA) is mandatory for all patients with primary abdominal aortic aneurysms (AAAs) in the Netherlands. The aims are to present the observed outcomes of AAA surgery against the predicted outcomes by means of V-POSSUM (Vascular-Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity). Adjusted mortality was calculated by the original and re-estimated V(physiology)-POSSUM for hospital comparisons.

Peritoneal dialysis underscores its merits in portal hypertensionrelated and nephrogenic ascites.

In the Western world, peritoneal dialysis (PD) is less frequently applied as substitute therapy in end-stage renal disease (ESRD). In the Netherlands the use of PD has decreased from 30.3 to 13.

Comparison of a collagen plug arterial closure device with manual compression after endovascular interventions for peripheral artery disease.

Objective: Arterial closure devices (ACDs) seem to be safe and effective to obtain hemostasis for cardiac interventions and diagnostic vascular procedures. However, only limited evidence is presented on therapeutic interventions in patients with peripheral atherosclerotic disease. We compared ischemic and hemorrhagic complications of an ACD vs manual compression (MC) after puncture of the femoral artery for endovascular lower extremity procedures.

Clarivein mechanochemical ablation of the great and small saphenous vein: Early treatment outcomes of two hospitals.

Objectives: Mechanochemical endovenous ablation is a novel technique for the treatment of great saphenous vein and small saphenous vein incompetence which combines mechanical injury of the endothelium with simultaneous infusion of liquid sclerosant. The main objective of this study was to evaluate early occlusion.

Methods: All consecutive patients who were eligible for the treatment with mechanochemical endovenous ablation were included.

Comparative study of venous arterialization and pedal bypass in a patient cohort with critical limb ischemia.

Objectives: Patients with critical limb ischemia (CLI) have a poor life expectancy, and aggressive revascularization is accepted as a means to maintain their independence in the end stage of life. The goal of this case-control study was to evaluate the clinical outcome of distal venous arterialization and compare this with pedal bypass surgery in patients with CLI, and to identify potential risk factors that could be used to effectively identify patients at high risk of graft occlusion and amputation.

Methods: A retrospective cohort of patients was treated for CLI using venous arterialization or pedal bypass between 2007 and 2012.

The influence of choice of therapy on quality of life in patients with neurogenic thoracic outlet syndrome.

Objectives: We aimed to compare quality of life (QoL) after surgical decompression of the thoracic outlet versus non-operative therapy in patients with neurogenic thoracic outlet syndrome (N-TOS).

Design And Methods: We retrospectively identified 46 patients, diagnosed with N-TOS between 1999 and 2008. Twenty-four operated and 22 conservatively treated patients were sent questionnaires on their current symptoms and QoL.

A ruptured aneurysm after stent graft puncture during computed tomography-guided thrombin injection.

Type II endoleaks occur in 5% to 10% of patients who are treated by endovascular aneurysm repair. A persistent type II endoleak combined with documented aneurysm expansion is generally considered an indication for intervention. Thrombin injection directly into the aneurysm sac is described as a safe and efficient treatment option.

Frequency and consequences of early in-stent lesions after carotid artery stent placement.

Purpose: To examine the prevalence of in-stent lesions 1 month after carotid artery stent placement with multidetector computed tomography (CT) angiography and to evaluate their possible causes and their consequences during 1-year follow-up.

Materials And Methods: Sixty-nine patients with symptomatic carotid artery stenosis underwent multidetector CT angiography of the carotid arteries 1 month after carotid artery stent placement. Patients were followed-up until 1 year after stent placement, when duplex ultrasonography (US) was performed.

Aprotinin does not diminish blood loss in elective operations for infrarenal abdominal aneurysms: a randomized double-blind controlled trial.

Surgery for abdominal aneurysm is associated with substantial blood loss. In cardiac surgery, aprotinin, a fibrinolysis inhibitor, has shown to reduce blood loss significantly. Our aim was to assess the effect of aprotinin, when administered during elective surgery of infrarenal abdominal aneurysm, on coagulation, blood loss, and morbidity.

Can transcutaneous oxygen tension measurement determine re-amputation levels?

Objective: To review the preoperative transcutaneous oxygen tension (TcPO2) measurements in patients having major lower leg amputation, and also consider the re-amputation rate, wound infection and the definitive level of amputation.

Method: A case-control study was performed in a consecutive cohort of 170 patients (1999-2003). Fifty-two patients underwent preoperative TcPO2 measurements (cases) and 118 patients did not (control).

Aortic stent-graft infection following septic complications of a kidney stone.

A 73-year-old man was treated because of a renal pelvis blowout of the left kidney for which he received a nephrostomy catheter without antibiotic prophylaxis. Almost a year previously this patient had undergone endovascular repair of a symptomatic infrarenal abdominal aorta aneurysm. Four weeks after the diagnosis and treatment of the ruptured renal pelvis, a new computed tomography scan and ultrasound-guided fine needle aspiration confirmed the diagnosis of infected aortic stent-graft.

The use of a percutaneous closure device for closure of an accidental puncture of the aortic arch; a simple solution for a difficult problem.

Percutaneous closure devices are now often used for closure of the femoral puncture site after percutaneous vascular interventions. We describe a case were an accidental puncture in the aortic arch during placement of a central venous catheter is successfully closed with a closure device.

The visceral perfusion system and distal bypass during thoracoabdominal aneurysm surgery: an alternative for physiological blood flow?

There are potential benefits to addition of visceral organ perfusion, by means of a 9-Fr. catheter system (octopus), to distal aortic perfusion during thoracoabdominal aneurysm surgery. However, in the literature there are reports of adverse effects.
