Removal of microcatheter entrapped in the middle cerebral artery in a neonate via common carotid arteriotomy.

A 2-day-old neonate was referred to the vascular surgery service owing to concerns of limb perfusion after entrapment of a microcatheter in the middle cerebral artery. The catheter was inserted via the umbilical artery to treat a vein of Galen arteriovenous malformation. This catheter inadvertently became entrapped owing to device failure, was cut at the insertion site, and left in situ for 3 months.

Emergency Endovascular Repair of Thoracic Aorta Via a Percutaneous Popliteal Approach Following an Iatrogenic Injury.

Iatrogenic arterial injuries are rare but well-recognised complications of spinal surgery. This paper presents a case of an iatrogenic arterial injury during a total en bloc spondylectomy resulting in significant haemorrhage and the patient's haemodynamic instability. The devastating complication was successfully treated with an emergency thoracic endovascular aortic repair via a percutaneous popliteal approach, while the patient remained in prone position.

Prone thoracic endovascular aortic repair via the popliteal artery for inadvertent vascular injury during spondylectomy: a case report.

Background: Vascular injury during spinal surgery is a dreaded complication associated with high morbidity and mortality. Repositioning the patient following such an injury could result in significant time delays and haemorrhage. Endovascular repair via popliteal access has never previously been described in the literature.

The Use of Extracorporeal Circulation to Facilitate the Resection of a Large Retroperitoneal Sarcoma With Major Vessel Involvement: A Single-Center Review of 20 Cases.

Objective: To describe the introduction of extracorporeal corporeal oxygenation (ECMO) to facilitate the surgical resection of large retroperitoneal sarcomas involving major vessels and to report preliminary outcomes.

Design: A case series.

Setting: At a tertiary university hospital and state sarcoma center.

Gentamicin-Containing Collagen Implant May Reduce Surgical Site Infections After Open Infrainguinal Arterial Revascularization.

Background: Deep-space surgical site infections carry significant morbidity and mortality. The evidence for gentamicin-containing collagen implants at reducing surgical site infections in open infrainguinal arterial surgery is limited. This study examined whether gentamicin-containing collagen implants reduces 30-day surgical site infections and their severity following open infrainguinal arterial surgery.

Directional Atherectomy of the Common Femoral Artery: Complications and Outcomes.

Background: The use of directional atherectomy (DA) with or without drug-coated balloon (DCB) may be considered for the management of common femoral artery (CFA) occlusive disease because of its minimally invasive nature with early mobilization, reduced incision complications, and infection rates. However, it has recognized complications, which may be related to the learning curve. We present our initial experience using DA and suggest changes that may, based on our practice, improve outcomes.

Hybrid treatment of an isolated immunoglobulin G4-related internal thoracic artery aneurysm.

True aneurysms of the internal thoracic artery (ITA) are rare and are associated with vasculitides, connective tissue diseases, and infections. We report a case of a 3-cm immunoglobulin G4-positive ITA aneurysm that was excised by a hybrid approach involving open ligation of the ITA origin and video-assisted thoracoscopic aneurysmectomy. This novel technique was able to acquire tissue for histopathologic diagnosis through a minimally invasive means.

A Technique of "Chimney Nellix" for the Management of Type 1a Endoleak After EVAR.

This report presents 3 procedures with visceral "chimney stenting" in conjunction with an endovascular aneurysm sealing (EVAS) device, known as chEVAS, for treatment of type 1a endoleak. It includes the first published chEVAS in a patient with previous fenestrated endovascular aneurysm repair (FEVAR). Cases include an 80-year-old man 8 years after FEVAR for a juxtarenal abdominal aortic aneurysm (AAA); an 85-year-old woman 9 months after endovascular aneurysm repair (EVAR) for a ruptured infrarenal AAA; and an 84-year-old woman 3 months after EVAR for a symptomatic infrarenal AAA.

Aspiration Thrombectomy versus Conventional Catheter-Directed Thrombolysis as First-Line Treatment for Noniatrogenic Acute Lower Limb Ischemia.

Purpose: To examine the efficacy, safety, and procedural costs of percutaneous aspiration thrombectomy (PAT) as a first-line treatment for noniatrogenic acute lower limb ischemia (ALI) compared with conventional catheter-directed thrombolysis (CDT).

Materials And Methods: All patients who underwent endovascular intervention for ALI from January 2015 to August 2017 were included. Fifteen patients were treated with the use of primary PAT and 27 patients were treated with the use of primary CDT.

Transradial approach for challenging vascular access interventions.

Background: Percutaneous interventional procedures for vascular access are usually performed using the draining cephalic or basilic vein. The transradial approach, which has been extensively investigated for coronary angiography and intervention, could be an attractive new technique for peri-anastomotic arteriovenous fistula stenosis.

Method: From June 2012 to February 2013, 30 patients with end-stage renal failure were evaluated for transradial vascular access intervention.
