Comparable failure rates of distal or proximal transcatheter arterial embolization (TAE) techniques for blunt splenic injuries have been reported. This study is to investigate the efficacy and complication of combining both TAE techniques. We included 26 patients of blunt splenic injuries for TAE therapy and randomized them into distal TAE and combined TAE groups. A prospective study was performed to compare their demographics, clinical parameters, hemograms, post-TAE splenic infarct volumes, splenic abscess and pancreatitis between the two groups...

OBJECTIVE: We describe our experience of single-incision laparoscopic splenectomy (SILS) for an unruptured aneurysm of the splenic artery. CLINICAL PRESENTATION AND INTERVENTION: A 73-year-old woman was diagnosed as having a splenic aneurysm which enlarged from 14 mm to 22 mm in diameter within two years. Due to contrast agent allergy, transcatheter arterial embolization could not be performed; therefore, SILS was performed with a 4 cm Z-shaped incision. The operative time and intraoperative blood loss were 132 min and 27 mL, respectively...

REVIEW
James E Dalen, Joseph S Alpert
Patients with cryptogenic strokes are more likely to have a patent foremen ovale than in the general population. It is speculated that these strokes are due to paradoxical embolism- that is passage of a venous thrombus across the patent foremen ovale to enter the arterial circulation, resulting in an embolic stroke. Venous thromboembolism is rarely present in these cases of cryptogenic stroke. Thousands of patients with cryptogenic strokes have undergone transcatheter closure of their patent foremen ovale via a variety of devices...

BACKGROUND: Blunt thoracic aortic injury (BTAI) is associated with a high mortality rate and the paradigm of treating patients with BTAI currently favours thoracic endovascular aneurysm repair (TEVAR) if possible. In BTAI, lethal malperfusion caused by a pseudoaneurysm has rarely been reported. We present the first report of a successful case in which a pseudoaneurysm causing the infrequent occurrence of lethal malperfusion and subsequent acute severe ischaemia in the distal portion of the thoracic descending aorta was overcome by veno-arterial extracorporeal membrane oxygenation (VA ECMO) as a bridging therapy until the initiation of TEVAR...

PURPOSE: Endovascular repair of true visceral artery aneurysms (VAAs) and pseudoaneurysms (VAPAs) with stent-grafting (SG) can simultaneously allow aneurysm exclusion and vessel preservation, minimizing the risk of ischemic complications. Our aim was to report a single-center experience on SG of visceral aneurysms, focusing on technical aspects, clinical outcome and mid-term patency. MATERIALS AND METHODS: Consecutive patients affected by VAAs-VAPAs and submitted to endovascular treatment were retrospectively reviewed, and SG cases with the self-expandable peripheral Viabahn stent-graft were analyzed (2003-2017)...

A 53-year-old diabetic male with sternal dehiscence presented with recurrent staphylococcus bacteremia 2years after coronary artery bypass grafting (CABG). He was found to have a giant right coronary artery (RCA) pseudoaneurysm and a coronary cameral fistula on imaging. Due to excessive surgical risk, the patient underwent percutaneous treatment with a 5mm Amplatzer vascular plug 4 (St. Jude Medical, St.Paul, MN). Post-procedure imaging showed successful cessation of flow into the pseudoaneurysm and follow-up CT scan demonstrated significant improvement in the size of the pseudoaneurysm...

REVIEW
Nicholas Rauh, John Gurley, Sibu Saha
Pulmonary arteriovenous malformations (PAVMs) are atypical vascular structures involving a direct connection between the pulmonary arterial and venous circulations. While PAVMs are a relatively uncommon disorder, unmanaged cases are at risk for the development of serious complications including embolization and infection. Since their first description in 1897, PAVMs have been identified and treated in a variety of ways. Advancements in diagnostic methods and operative techniques have allowed for more effective treatment of the disease...

BACKGROUND: Cardiopulmonary resuscitation-related bleeding, especially internal mammary artery injuries, can become life-threatening complications after initiating venoarterial extracorporeal membrane oxygenation owing to the frequent involvement of concomitant anticoagulant treatment, antiplatelet treatment, targeted temperature management, and bleeding coagulopathy. We report the cases of five patients who experienced this complication and discuss their management. CASE PRESENTATION: We retrospectively evaluated five patients with cardiopulmonary resuscitation-related internal mammary artery injuries who were treated between February 2011 and February 2016 at our institution...

Interventional embolization is a popular minimally invasive vascular therapeutic technique and has been widely applied for hepatocellular carcinoma (HCC) therapy. However, harmful effects caused by transcatheter arterial chemoembolization (TACE) and radioembolization, such as the toxicity of chemotherapy or excessive radiation damage, are serious disadvantages and significantly reduce the therapeutic efficacy. Here, a synergistic therapeutic strategy combined transcatheter arterial embolization and magnetic ablation (TAEMA) by using PLGA-magnetic microspheres (MMs) has been successfully applied to orthotopic VX2 liver tumors of rabbits...

Transcatheter arterial chemoembolization (TACE) is used as a palliative treatment for unresectable hepatocellular carcinoma (HCC) worldwide. Recently, a novel drug delivery-embolic agent, the drug-eluting bead (DEB), was introduced for TACE. There are a few reports of tumor hemorrhage after TACE using DEB (DEB-TACE) for HCC. However, there have not been any reports of hemobilia immediately after DEB-TACE for an HCC with intrahepatic bile duct invasion. Here, the first such case is reported. A 71-year-old woman was admitted to our hospital to undergo DEB-TACE for multiple HCCs with worsening left intrahepatic bile duct dilatation...

Development of aspergilloma is common in cases with a fungus ball-like shadow in cavities due to old tuberculosis. Some reports have shown that blood clots tend to appear as a fungus ball-like shadow. A 71-year-old man with a history of pulmonary tuberculosis presented with a fungus ball-like shadow in an old cavity and hemoptysis. There was no evidence of aspergillus infection on various examinations. We confirmed a blood clot and aneurysm of an artery under direct vision by bronchoscopy. A lateral thoracic artery aneurysm was detected by angiography...

RATIONALE: Abdominal apoplexy is a rare and fatal emergency event, which is coined as a comparison to the cerebrovascular apoplexy. The exact mechanism of abdominal apoplexy was unclear, but arteriosclerosis, hypertension, abdominal aneurysm, and other predisposing angiopathy were considered to be the main reasons of abdominal apoplexy. The development of the imaging technology gave us more opportunities to confirm the diagnosis of abdominal apoplexy. However, the diagnosis and identification of the bleeding sites still continued to be a challenge...

A 80-year-old man was admitted to catheterization room for an acute infero-lateral ST-elevation myocardial infarction (STEMI). Coronary angiography showed a thrombotic occlusion of the second left marginal branch, and normal other coronary arteries. The thrombo-embolic mechanism of the STEMI, and the infectious context in this patient who had had a transcatheter aortic valve implantation (TAVI) two months earlier, led us to suspect a bioprosthesis endocarditis. It was confirmed by transthoracic and transoesophageal echocardiography, which showed an aortic-mitral curtain abscess and aortic bioprosthesis vegetations, associated to Enterococcus faecalis bacteriemia...
