Arterial gas embolism is a catastrophic event. Bubbles in the arterial circulation may lodge in the brain and cause infarction in the affected area and/or in a coronary vessel causing acute myocardial ischaemia. There is no well-defined window of time beyond which a response to hyperbaric oxygen is not expected. Major improvement may occur if the patient is treated as soon as possible, but is less likely in divers with severe decompression illness who have delayed intervention. We report on a 51-year-old, male rebreather diver who suffered loss of consciousness and cardiovascular collapse within minutes of a 30-metre deep dive at a remote Micronesian dive site...

BACKGROUND: Thromboelastography (TEG) in venous air embolism (VAE) has been poorly studied. We induced coagulation abnormalities by VAE in a rat model, assessed by TEG with and without mexiletine, a lidocaine analogue local anesthetic. METHODS: Twenty-three Sprague Dawley rats instrumented under isoflurane anesthesia and allowed to recover five days prior to the experiments were randomized into three experimental groups: 1) VAE (n = 6); 2) VAE and mexiletine (n = 9); and 3) normal saline (NS) alone (control group, n = 8)...

Acute thrombosis of the lower limb deep veins remains one of the most common vascular diseases. It is characterised by formation of thrombotic masses in the system of the deep veins of the lower extremities. A serious complication associated with deep vein thrombosis is pulmonary embolism. In rare cases, under certain conditions a massive and disseminated blockade of the venous outflow with thrombotic masses may lead to ischaemia of the extremity with the formation of superficial and deep necroses and later on to gangrene...

The problem of venous thromboembolic complications (VTECs) in patients with cardiovascular implantable electronic devices (CIEDs) is extremely important today because of an annually increasing number of surgical interventions for life-threatening arrhythmias and chronic heart failure. There are hitherto no clearly defined reliable risk factors for VTECs due to heterogeneity of the available literature data. Some sources point to elevated thrombus formation in patients with a large number of electrodes, in repeat operative interventions, in the presence of a temporary pacemaker, in implantation on the left side, silicon cover of an electrode, others refute these facts...

The method of cyanoacrylate-mediated obliteration of subcutaneous veins is known to be an alternative to thermal endovascular obliteration and eliminates the need for tumescent anaesthesia. This technique is based on glue-induced damage to the venous intima, followed by immune response according to the delayed-type hypersensitivity principle. The authors report herein their first experience with using cyanoacrylate-mediated embolization in treatment of patients presenting with varicose veins. The operation was carried out using the VenaSeal closure system (Medtronic)...

A 62-year-old man presented to the emergency department with massive hemoptysis. After bronchial artery embolization, he developed ischemic myelitis, a rare complication in this setting for which no specific therapy is currently recommended. The symptoms were managed with lumbar drainage of cerebrospinal fluid and blood pressure augmentation therapy. To our knowledge, this is the first report of using lumbar drainage of cerebrospinal fluid and blood pressure augmentation in the treatment of anterior medullary ischemia after bronchial artery embolization for massive hemoptysis...

BACKGROUND: Direct oral anticoagulants (DOACs) have a better risk benefit profile in Asian patients with atrial fibrillation (AF). Whether treatment effects could be modified by drug class and dependency on renal elimination of studied agents has not yet been explored. METHODS: We searched PubMed, CENTRAL, and CINAHL databases through November 2016 for phase III randomized controlled trials comparing DOACs with warfarin in patients with AF. Efficacy and safety outcomes were pooled according to drug class and dependency on renal elimination of DOACs and were compared with the Mantel-Haenszel fixed-effects model...

Background Treatment of true ophthalmic artery (OA) or anterior choroidal artery (AChA) aneurysms with preservation of the parent vessel may be challenging. Flow diverters have limitations when dealing with branch vessels arising from the aneurysm sac. Visual loss or AChA territory infarcts have been reported both for surgical and endovascular treatment. Methods We evaluated the safety and efficacy of an open-cell design, laser-cut, self-expanding Nitinol stent, and use of cone-beam computed tomography (CBCT) for stent-assisted coil embolization...

Despite major developments in treating intracranial aneurysms by endovascular coil embolization, complete occlusion of the entire aneurysmal neck remains a problem. We present a novel endovascular strategy for middle- and large sized aneurysms called the "hemispheric divided coiling technique" and compare the short-term follow-up results of this technique with those of conventional coil embolization. Ten patients (mean age, 69.7 ± 9.7 years) with middle- or large-sized ruptured or unruptured intracranial aneurysms (mean maximum aneurysmal diameter, 12...

The use of 8-F balloon guide catheter (BGC) for proximal flow control was previously shown to prevent distal embolic complications during mechanical clot retrieval in patients with acute ischemic stroke. In this retrospective study, the utility of 8-F BGCs for proximal flow control during endovascular coiling of anterior circulation aneurysms was investigated. Patients who underwent endovascular coiling for anterior circulation aneurysms between August 2013 and December 2016 were retrospectively analyzed. Among a total of 152 patients included in this series, 64 patients presented with aneurysmal rupture, whereas the aneurysms were detected incidentally or due to mass effects in the remaining patients...

Isolated pubic ramus fractures are common and generally uncomplicated injuries in the elderly. However, pubic ramus fractures are closely related to important vascular structures. The corona mortis, located in the retropubis, has an important anastomotic value, as it serves as a communication between the internal and external iliac vessels. The following case report describes an 88-year-old male who was diagnosed with a right superior pubic ramus fracture, which led to a severe picture of hemodynamic instability...

BACKGROUND: The resuscitative endovascular balloon occlusion of the aorta, because of its efficacy and feasibility, has been widely used in treating patients with severe torso trauma. However, complications developing around the site proximal to the occlusion by resuscitative endovascular balloon occlusion of the aorta have almost never been studied. CASE PRESENTATION: A 50-year-old Japanese woman fell from a height of approximately 10 m. At initial arrival, her respiratory rate was 24 breaths/minute, her blood oxygen saturation was 95% under 10 L/minute oxygenation, her pulse rate was 90 beats per minute, and her blood pressure was 180/120 mmHg...

Transcatheter arterial or venous embolization has been widely used to address solid tumors by occluding the tumor-feeding vessels. It is also performed to treat portosystemic shunts and to stop bleeding by repair of the site of trauma. Commonly used embolic materials are gelatin sponges, coils, beads, and liquid agents such as absolute ethanol, histoacyryl, and onyx. In the field of interventional radiology, embolotherapy is performed routinely. Liquid embolization agents have different characteristics. Their coagulation time, the inflammatory reaction of the vascular wall or surrounding tissue, and their adhesion to the vascular wall vary...
