Nutcracker syndrome (a Delphi consensus).

Background: Nutcracker syndrome (NCS) describes the symptomatic compression of the left renal vein between the aorta and superior mesenteric artery. Whereas asymptomatic compression is a common radiological finding, patients with NCS can report a range of symptoms. There are no specific diagnostic criteria and interventions include a range of open surgical and endovascular procedures.

Single-session catheter-directed lysis using adjunctive clot fragmentation with power pulse spray only is a fast, safe, and effective option for acute pulmonary embolism.

Objective: Single-session, catheter-directed thrombolysis (CDT) with adjunctive power pulse spray (PPS) only, without thrombectomy, was evaluated for its safety and effectiveness. We performed a single-center, retrospective analysis of prospectively collected data.

Methods: Patients with high-risk or intermediate-risk pulmonary embolism (PE) who met the inclusion criteria and underwent a single session of CDT-PPS were included in the study.

Review of the literature supporting international clinical practice guidelines on iliac venous stenting and their applicability to Australia and New Zealand practice.

Background: The overall goal of this report is to provide a high-level, practical approach to managing venous outflow obstruction (VOO).

Methods: A group of vascular surgeons from Australia and New Zealand with specific interest, training, and experience in the management of VOO were surveyed to assess current local practices. The results were analyzed and areas of disagreement identified.

Pharmacomechanical thrombectomy of iliofemoral deep vein thrombosis is associated with a low incidence of post-thrombotic syndrome and perioperative complications.

Background: Iliofemoral deep venous thrombosis (IFDVT) is associated with an incidence of post-thrombotic syndrome (PTS) of up to 50%. PTS is associated with high morbidity, impaired quality of life and a significant economic burden. The aim of the current study was to assess the impact of a single session pharmacomechanical thrombectomy (PMT), dedicated venous stents and a risk mitigation protocol on the rate of PTS.

Iliac vein stenting and pregnancy.

Venous stenting is the mainstay treatment of symptomatic iliofemoral venous outflow obstruction. However, because pregnancy and the postpartum period are hypercoagulable, concerns exist regarding stent placement in women of childbearing age. We performed a systematic review up to April 2023 of studies reporting on the performance of venous stents in women who subsequently became pregnant.

RETRACTED: Australian and New Zealand Society for Vascular Surgery clinical practice guidelines on venous outflow Obstruction of the femoral-iliocaval veins.

Background: The overall goal of this report is to provide a high-level, practical approach to managing venous outflow obstruction (VOO) in Australia and New Zealand.

Methods: A group of vascular surgeons from the Australian and New Zealand Society for Vascular Surgery with specific interest, training, and experience in the management of VOO were surveyed to assess current local practice. The results were analyzed and areas of disagreement identified.

Outcomes of dedicated iliac venous stents during pregnancy and postpartum.

Objective: The aim of this study was to assess the performance of dedicated iliac venous stents during subsequent pregnancy and postpartum, including stent patency and stent integrity, as well as incidence of venous thromboembolism and bleeding complications.

Methods: This study included retrospective analysis of prospectively collected data of patients attending a private vascular practice. Women of child-bearing age who had received dedicated iliac venous stents were included in a surveillance program and then, for any subsequent pregnancies, followed the same pregnancy care protocol.

An estimate of the economic burden of venous leg ulcers associated with deep venous disease.

Introduction: Venous leg ulcers (VLU) embody the most severe stage of the broad spectrum of chronic venous disease. Approximately 40% of patients with VLU present with the underlying deep venous disease (DVD). Although the data are scarce, these deep venous disease-related VLU (DRV) are thought to have higher recurrence rates and a substantial economic burden.

Transabdominal duplex ultrasound and intravascular ultrasound planimetry measures of common iliac vein stenosis are significantly correlated in a symptomatic population.

Objective: The objectives of the present study were to determine the validity of transabdominal duplex ultrasound (TAUS) against the reference standard of intravascular ultrasound (IVUS) examinations for the detection of iliac vein obstruction (IVO).

Methods: We analyzed the data from patients at a private vascular laboratory who had undergone IVUS investigation with an intention to treat because of symptoms of chronic venous insufficiency and a high suspicion of IVO. These patients had also previously undergone a TAUS examination at the same location.

Common iliac vein obstruction in a symptomatic population is associated with previous deep venous thrombosis, and with chronic pelvic pain in females.

Objective: The objectives of this study were to determine the incidence of common iliac vein obstruction, gonadal vein incompetence, and renal vein compression/stenosis and to ascertain which referral reasons were associated with common iliac vein obstruction and gonadal vein incompetence in a population symptomatic for chronic venous insufficiency.

Methods: Data were obtained from patients, at least 18 years old, who were referred to a private vascular laboratory for venous duplex ultrasound examination between 2016 and 2017. Transabdominal ultrasound was used to assess the iliac, gonadal, and renal veins in a dedicated protocol.

Single-session catheter-directed lysis using adjunctive power-pulse spray with AngioJet for the treatment of acute massive and submassive pulmonary embolism.

Objective: An alternative single-session catheter-directed thrombolysis (CDT) method using adjunctive power-pulse spray (PPS) technique (with the AngioJet system; Boston Scientific, Fremont, Calif) was investigated to evaluate its safety and effectiveness in the treatment of acute massive and submassive high-risk pulmonary embolism (PE).

Methods: Between May 2016 and July 2018, patients diagnosed with extensive massive or submassive PE who triggered intensive care unit involvement and were considered for escalation of treatment were offered CDT with adjunctive PPS technique, provided they met the clinical inclusion criteria. Clinical success was defined as stabilization of hemodynamic parameters, resolution of hypoxia, and survival to discharge.

Multicentre, randomised, blinded, control trial of drug-eluting balloon vs Sham in recurrent native dialysis fistula stenoses.

Background: Endovascular treatment of autogenous arteriovenous haemodialysis fistula stenosis has high reintervention rates. We investigate the effect of drug-eluting balloons in the treatment of recurrent haemodialysis fistula stenosis.

Methods: This is a randomised, controlled, investigator-initiated and run, prospective, blinded, multicentre trial.

Using bilateral iliac branch devices for endovascular iliac aneurysm repair.

Introduction: The endovascular repair of bilateral iliac aneurysms using bilateral Iliac Branch Devices (IBDs) has been infrequently performed and reported.We aim to describe this technique and report on the results of our case series.

Methods: Three different device designs are available.

Endovascular treatment for aortic disease: is a surgical environment necessary?

Objective: Interventional radiologists, cardiologists, and vascular surgeons are capable of performing endovascular procedures successfully in their respective environments. Suboptimal anatomy or intraoperative technical problems can be encountered, and endovascular management alone is not always suitable. The objectives of this study were to define the incidence of adjunctive surgical techniques, to discuss the rationale for endovascular reconstruction in a well-developed surgical environment, and to assess the effect of experience on the incidence of adjunctive repair.
