Skin necrosis overlying an arteriovenous fistula at the cannulation site is a common and potentially life-threatening problem, often associated with underlying aneurysm formation. Arteriovenous fistula-skin necrosis generally requires resection of surrounding skin margins and the underlying aneurysmal vessel wall, allowing repair with healthy tissue of the arteriovenous fistula in addition to closure of soft tissue and skin. In patients with insufficient fistula length, salvage of these arteriovenous fistulas may result in difficult or insurmountable cannulation issues leading to attempts at one-needle cannulation dialysis or, most often, catheter placement...

Fibromuscular dyplasia (FMD) is an under-recognized non-atherosclerotic, non-inflammatory arteriopathy that occurs most commonly in middle-aged women, but may affect individuals of all age groups. FMD may result in stenosis, aneurysm, dissection, occlusion, or arterial tortuosity. Recently published data demonstrated a genetic association of FMD with a variant in the phosphatase and actin regulator 1 gene (PHACTR1), substantiating that the pathogenesis of this condition has genetic contribution. The renal and extracranial carotid and vertebral arteries are most often involved, although any arterial bed may be affected...

BACKGROUND: Noncompressible junctional and truncal hemorrhage remains a significant cause of combat casualty death. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an effective treatment for many junctional and noncompressible hemorrhages. The current hospital standard for time of placement of REBOA is approximately 6 minutes. This study examined the training process and the ability of nonsurgical physicians to apply REBOA therapy in an austere field environment. METHODS: This was a skill acquisition and feasibility study...

BACKGROUND: The management of noncompressible torso hemorrhage remains a significant issue at the point of injury. Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been used in the hospital to control bleeding and bridge patients to definitive surgery. Smaller delivery systems and wirefree devices may be used more easily at the point of injury by nonphysician providers. We investigated whether independent duty military medical technicians (IDMTs) could learn and perform REBOA correctly and rapidly as assessed by simulation...

AMPLATZER devices preceded WATCHMAN occluder in 2002 for catheter-based left atrial appendage occlusion. The AMPLATZER technique facilitates simultaneous closure of atrial shunts using two devices through one gear. Randomized WATCHMAN follow-up data showed a mortality benefit over warfarin. AMPLATZER data make this likely valid for the strategy. Particularly young people with atrial fibrillation should be offered left atrial appendage occlusion because the risk is confined to the intervention and early postintervention period...

Objective : Endovenous radiofrequency ablation (RFA), a relatively new technique for treating great saphenous varicose veins, is less invasive compared with stripping surgery. This study examined the mid-term safety and effectiveness of RFA for varicose veins. Materials and Methods : We enrolled 104 patients (147 limbs) who underwent RFA for varicose veins of the lower extremities (females, 67; 64.4%). The mean age was 68.9±9.2 years (39-85 years). In 121 limbs (82.3%), there were great saphenous veins. All patients were observed as outpatients for 12 months after the procedure...

OBJECTIVE: Although most intracranial aneurysms can be treated with microsurgery or endovascular procedure alone, a subset of aneurysms may require a combined approach. The purpose of this study was to assess the efficacy of endovascular interventions combined with bypass surgery for the treatment of complex intracranial aneurysms. METHODS: We retrospectively reviewed medical records from a prospectively maintained patient database to identify patients who underwent endovascular treatment of an intracranial aneurysm at our institutes from 2007 to 2017...

Endovascular salvage of failed surgical bypasses has been scantly reported for treatment of infrainguinal occlusive disease. While catheter-directed thrombolysis and/or mechanical thromboembolectomy have been the mainstay of endovascular salvage of previous bypass grafts, native vessel recanalization remains seldom attempted. Herein, we present a unique approach to native vessel recanalization of a chronically thrombosed popliteal artery aneurysm for non-healing distal ulceration.

PURPOSE: A complicated course of the femoral route for neurointervention can prevent approaching the target. Thus, we determined whether transcervical access in the hybrid angiosuite is applicable and beneficial in real practice. METHODS: From January 2014 to March 2017, this approach was used in 17 of 453 (3.75%) cases: 11 cerebral aneurysms (4 ruptured, 7 unruptured), 4 acute occlusions of the large cerebral artery, 1 proximal internal carotid artery (ICA) stenosis, and 1 direct carotid cavernous fistula (CCF)...

We report a case of coronary sinus (CS) injury with a retrograde cardioplegia catheter and repair compromising CS patency. This resulted in acute global cardiac dysfunction shortly after weaning from bypass, which reversed after patch repair with confirmed CS patency. The case shows that acute CS occlusion may not be tolerated in some humans.

A 70-year-old woman with hepatitis C cirrhosis underwent balloon-occluded retrograde transvenous obliteration for hepatic encephalopathy due to spleno-renal shunt. Because the shunt was thick, long, and winding, we used a coaxial and double interruption system, which enables the effective occlusion of the drainage route, and shape-memory coils, which are more physically stable than conventional metallic coils because they form three-dimensional loops. The patient was successfully treated with the combined usage of these devices, resulting in a normal serum ammonia level...

The purpose of this article is to share the efforts of one institution in reducing risk of central line-associated bloodstream infections (CLABSIs). The aim is to review alteplase use as a marker for peripherally inserted central catheter (PICC) occlusions, which may increase risk of CLABSIs. The discovery that alteplase use increased with the number of PICC lumens allowed for exploration of ordering and placement practices. Following education, placement of double-lumen PICCs decreased.

Acute thrombotic occlusions of the large vessels, such as internal carotid artery, arms and legs arteries, and intracranial vessels, frequently require multiple techniques such as selective thrombolysis, manual aspiration, and stent retrievers for mechanical thrombectomy with combination of the mentioned techniques. Because of the massive thrombotic burden associated with these conditions, the response to systemic intravenous thrombolysis is poor. We present a case of a successful massive thrombi aspiration in a single attempt using an 8Fr guide catheter with aspiration syringe, subsequent ipsilateral middle cerebral artery mechanical thrombectomy, and axillary artery clot disruption attempt in a patient with acute ischemic stroke, right arm critical ischemia, and persistent atrial fibrillation...

INTRODUCTION: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a technique to control haemorrhage by placing a retrograde catheter in an artery and inflating a balloon at its tip. This retrospective study aimed to evaluate the proportion of injured people who could potentially have benefited from this technique prior to hospitalisation, including on the scene or during transport. METHODS: A retrospective analysis was conducted of all patients with trauma registered in the Paris Fire Brigade emergency medical system between 1 January and 31 December 2014...

OBJECTIVE: Application of extracorporeal membrane oxygenation (ECMO) for life support has been widely used in various fields of resuscitation. When the common femoral artery (CFA) is used during cannulation for ECMO support in adults, it is often complicated by limb ischemia. Placement of distal perfusion catheter (DPC) can reduce the incidence of limb ischemia and increases the likelihood of limb preservation, but selection criteria is uncertain. METHODS: This is a retrospective study...

Tip separation of a Crosser catheter is a serious complication; however, there is limited information on bailout methods. Here, we describe a case of successful retrieval of the separated tip of a Crosser catheter using a 2-wire technique with a gooseneck snare. A 76-year-old woman with a history of hemodialysis and diabetes mellitus who developed ulcers on her right toes was diagnosed as having critical limb ischemia and underwent transfemoral antegrade endovascular treatment of the anterior tibial artery (ATA)...
