The patient received endovascular embolization of a carotid-cavernous fistula with ...

Summary: We propose this combined balloon occlusion and surgical technique to treat selected patients with large-giant aneurysms not suitable for a pure endovascular or surgical approach. After an occlusion test a non detachable balloon catheter is positioned deflated proximally to the neck of the aneurysm under general anesthesia. The patient ...

BACKGROUND: The main structures anterior to the trachea are frequently poorly visualized by trans-oesophageal echocardiography (TEE) because of the tracheal air column. We studied a new acoustic window for TEE imaging of large vessels anterior to the trachea by using a saline-filled endotracheal balloon. METHODS: Cardiac surgery patients were studied. ...

The aim of this article is to report our experience in the diagnosis of two cases of iliac artery endofibrosis or arteriopathy, a rare entity occurring in high-performance athletes, presenting with intermittent claudication (right-sided in both) after maximal exercise. External iliac artery endofibrosis or arteriopathy is a likely diagnosis in ...

Percutaneous aortic valvuloplasty is reportedly a useful tool for the management of critical and severe aortic stenosis with cardiogenic shock. However, early percutaneous coronary intervention for cardiogenic shock is beneficial for elderly patients with acute myocardial infarction. We describe a patient with critical aortic stenosis who presented with severe coronary ...

If a large amount of debris or thrombus dislodges from a lesion because of dilation of the stenotic or occluded lesion in the hemodialysis access fistula when angioplasty is performed, it may move into the pulmonary artery via the central vein, resulting in pulmonary embolism. A novel sheath has been ...

To our knowledge we present the first case of use of a cutting balloon in the treatment of BBS through a percutaneous approach.

The aim of this article is to review the mechanism, technical characteristics, biological response and clinical applications of cutting balloon angioplasty in peripheral vessels. The cutting balloon is a non-compliant, balloon catheter equipped with three-to-four microtome-sharp atherotomes. When used appropriately, it is safe and easy to use, with a high ...

BACKGROUND: Interruption of antegrade cerebral perfusion results in transient neurologic intolerance in some patients undergoing carotid angioplasty and stenting (CAS). This study sought to evaluate factors that contributed to the development of cerebral ischemia during PercuSurge balloon occlusion and techniques used to allow successful completion of the CAS procedure. METHODS: ...

Massive intraabdominal hemorrhage sometimes requires urgent hemostatic surgical intervention. In such cases, its rapid stabilization is crucial to reestablish a general hemodynamic status. We used an aortic occlusion balloon catheter in patients with massive intraabdominal hemorrhage occurring after hepato-pancreato-biliary surgery. An 8-French balloon catheter was percutaneously inserted into the aorta ...

Failures in angioplasty balloons are investigated using typical destructive techniques. The material properties of moulded balloons are derived from tensile tests and used to establish the reasons for failure of the balloons. Thermoelastic stress analysis is used to determine the stress distribution in the balloons, and a means of interpreting ...

A 77-year-old patient suffering from life-threatening pulmonary artery bleeding after pulmonary lobectomy was resuscitated but had refractory cardiogenic shock after the bleeding was controlled.

Transient left ventricular apical ballooning is an acute cardiac syndrome characterised by an abrupt onset of chest pain and is usually associated with anterior electrocardiographic changes. The observed apical ballooning of the left ventricle is usually reversible and develops in the absence of significant atherosclerotic coronary artery disease. Here we ...

BACKGROUND: The extracranial, internal carotid artery balloon test occlusion is helpful in predicting ischemic stroke resulting from operative occlusion of the internal carotid artery. However, balloon test occlusion is falsely negative in up to 20% of patients. With selected use of the paraophthalmic internal carotid artery balloon test occlusion, our ...

Vessel perforation is an uncommon but potentially life-threatening complication of percutaneous coronary intervention and is often associated with the use of atheroablative devices. While effective management means are currently available, such as PTFE-covered stent, pericardiocentesis, and perfusion balloon, a timely and skillful approach is of paramount importance to solve this ...

The success of angioplasty depends on a balance between two conflicting objectives: maximization of artery lumen patency and minimization of mechanical damage. A finite element model for the patient-specific prediction of angioplasty is proposed as a potential tool to assist clinicians. This paper describes the general methodology and the algorithm ...

The syndrome of "apical ballooning" consists of an acute onset of transient extensive akinesia of the apical portion of the left ventricle, without significant stenosis on the coronary angiogram. The syndrome is accompanied by chest symptoms, electocardiographic changes, and limited release of cardiac markers disproportionate to the extent of akinesia. ...

PURPOSE: To report the fortuitous discovery of a false aneurysm 7 years after cutting balloon angioplasty for severe renal artery fibromuscular dysplasia in a child. CASE REPORT: A 3-year-old girl with neurofibromatosis was referred to our institution because of high blood pressure (220/160 mmHg). Computed tomography identified coarctation of the ...

OBJECTIVE: Balloon angioplasties of stenotic or occluded infrapopliteal arteries may be helpful in selected high-risk patients threatened with limb loss. Thus far, these procedures have demanded fluoroscopy and the injection of potentially nephrotoxic contrast material. Herein, we proposed a new alternative to avoid the harmful effects of radiation exposure and ...

BACKGROUND: The technique of balloon angioplasty of infrainguinal arteries requires standard arteriography and fluoroscopic guidance. We attempted to perform this procedure under duplex guidance to avoid the use of nephrotoxic contrast material and radiation exposure in patients with renal insufficiency. METHODS: Over 16 months, 28 patients (17 men) with serum ...

A 48-year-old woman presented to her local hospital with chest pain. Her electrocardiogram showed incomplete right bundle branch block, diffuse ST segment elevation and QTc prolongation. Shortly after admission, she became hypotensive and was referred for a coronary angiogram. Her coronary arteries were normal, but left ventriculography showed morphological changes ...

A case of placenta percreta was referred at 31 weeks' gestation. We performed a cesarean hysterectomy preceded by placement of occlusive balloon catheters at bilateral common iliac arteries at 34 weeks' gestation. This simple and safe technique provides satisfactory efficacy for control of profuse bleeding during operation, with blood loss ...

OBJECTIVES: We sought to evaluate the efficacy and safety of a novel cryothermal balloon ablation system in creating pulmonary vein (PV) isolation. BACKGROUND: Pulmonary vein isolation using standard radiofrequency ablation techniques is limited by procedure-related complications, such as thrombus formation and PV stenosis. Cryothermal ablation may reduce the risk of ...

The intraaortic balloon pump (IABP) is frequently used in the management of cardiac failure in the setting of myocardial infarction or as a bridge for coronary revascularisation surgery. The IABP is usually inserted through the femoral artery. Occasionally severe aorto-iliac occlusive disease prevents the retrograde passage of the balloon, in ...

For infants with valvar aortic stenosis, balloon aortic valvuloplasty has supplanted surgical valvotomy as the initial treatment of choice at most institutions. Technological innovations have resulted in further miniaturization of balloon dilation catheters, allowing this procedure to be performed through smaller sheath sizes. Currently, the Tyshak-Mini balloon dilation catheter (B. ...

OBJECTIVES: To describe technical aspects of successful fetal aortic valvuloplasty, with particular attention to balloon size.
