BACKGROUND: Reconstruction of the aortic major branches during thoracic endovascular aortic repair is complicated because of the complex anatomic configuration and variation of the aortic arch. In situ laser fenestration has shown great potential for the revascularization of aortic branches. This study aims to evaluate the feasibility, effectiveness, and safety of in situ laser fenestration on the three branches of the aortic arch during thoracic endovascular aortic repair. METHODS AND RESULTS: Before clinical application, the polytetrafluoroethylene and Dacron grafts were fenestrated by an 810-nm laser system ex vivo, which did not damage the bare metal portion of the endografts and created a clean fenestration while maintaining the integrity of the endografts...

Thoracic endovascular aortic repair( TEVAR) for thoracic aortic aneurysm has been established as a 1st-line therapy, especially in high-risk cases, with device improvements and the appearance of various procedures, but there are still cases of anatomical adaptation. On the other hand, several countermeasures have been developed, but there are no commercially available devices for fenestrated or branched stent grafts in Japan. Moreover, complications such as cerebral infarction, organ ischemia and bypass occlusion and infection are pointed out in popular debranch TEVAR...

BACKGROUND AND OBJECTIVES: Multiple laser systems have been investigated for their use in stapes surgery in patients with otosclerosis. The diode 1,470 nm laser used in this study is an attractive laser system because it is easily transported and relatively inexpensive in use. This wavelength has relative high absorption in water. This study aimed to investigate the mechanical, thermal, and acoustic effects of the diode 1,470 nm laser on a stapes in an inner ear model. MATERIALS AND METHODS: Experiments were performed in an inner ear model including fresh frozen human stapes...

BACKGROUND: Fenestrated endovascular aneurysm repair (FEVAR) is increasingly being used for juxtarenal aortic aneurysms. The aim of this study was to review long-term results and assess the importance of changing stent-graft design on outcomes. METHODS: This was a retrospective review of all patients who underwent FEVAR within a single unit over 12 years (February 2003 to December 2015). Kaplan-Meier analysis of survival, and freedom from target vessel loss, aneurysm expansion, graft-related endoleak and secondary intervention was performed...

Acquired diaphragmatic perforation leading to massive hepatic hydrothorax and respiratory failure is a rare complication of microwave ablation (MWA) of hepatocellular carcinoma (HCC). Imaging modalities to detect pleuroperitoneal communication remain poorly described. We report a nuclear imaging technique used to efficiently diagnose and locate diaphragmatic defects. A 57-year-old male with cirrhosis and HCC presented with respiratory distress after undergoing MWA of a HCC lesion. He was admitted to the intensive care unit for noninvasive positive pressure ventilator support...

INTRODUCTION: Aneurysm regression and target vessel patency during early and mid-term follow-up may be related to the effect of stent graft configuration on the anatomy. We quantified geometry and remodeling of the renal arteries and aneurysm following fenestrated (F-) or snorkel/chimney (Sn-) endovascular aneurysm repair (EVAR). METHODS: 29 patients (mean age, 76.8±7.8 years) treated with F- or Sn-EVAR underwent computed tomography angiography at pre-op, post-op, and follow-up...

PURPOSE: We present two different cases of chronic aortic dissection, where we opted to land the stent graft into the false lumen to treat the associated aneurysm. CASE DESCRIPTIONS: For the first case, the goal of thoracic endovascular aortic repair (TEVAR) was to exclude the aneurysm from within the false lumen, because of a slit-like true lumen. In the second case, the visceral arteries came off the false lumen, with the renal vessels from the true lumen. False lumen TEVAR was performed and the infra-renal aorta fenestrated, as to ensure adequate perfusion...

BACKGROUND: Fenestrated endovascular aneurysm repair (FEVAR) allows endovascular treatment of thoracoabdominal and juxtarenal aneurysms previously outside the indications of use for standard devices. However, because of considerable device costs and increased procedure time, FEVAR is thought to result in financial losses for medical centers and physicians. We hypothesized that surgeon leadership in the coding, billing, and contractual negotiations for FEVAR procedures will increase medical center contribution margin (CM) and physician reimbursement...

BACKGROUND: Aortic dissection (AD) is the most common aortic catastrophe. Carotid artery dissection due to extension of AD (CAEAD) is one severe complication of this condition. Despite years of refinement in the techniques for repair of AD, the optimal management strategy for CAEAD remains yet to be described. We hypothesized that CAEAD eventually resolves on antiplatelet therapy with a low but not insignificant risk of cerebrovascular accident (CVA). METHODS: This was a single-institution retrospective review of patients admitted with nontraumatic coincident aortic and carotid dissection between 2001 and 2013...

Type II endoleak is the most frequent procedure-related complication during endovascular aneurysm exclusion. Actually there is little controversy in the management of type I and III endoleak, while type II endoleak still generates conflicting reports about their timing and type of treatment. Currently, the intervention is needed only in case of sac enlargement, but not in case of persistent endoleak alone. We report the case of a 77 year-old man treated with a custom-made branched/fenestrated endograft for a type III thoracoabdominal aortic aneurysm...

Surgical treatment is often necessary for patients with symptomatic or complicated polycystic liver diseases (PLD). In this paper, we describe a 52-year-old female with symptomatic PLD that had resulted in the formation of liver cysts, the largest of which was 23 cm in diameter. The patient underwent mini-laparoscopic fenestration through 5-mm abdominal trocars. The walls of the cysts were unroofed using a harmonic scalpel. Four thickened rubber-like pieces of specimens (sizes ranged between 9 × 6 × 0...

BACKGROUND: Vaginal aplasia occurs in 1 in 5,000-10,000 female live births. In this report, we evaluated a novel dual-force vaginoplasty technique for treatment of 11 patients with segmental vaginal aplasia. TECHNIQUE: The principle of the approach is to thin the atretic part between two counteracting forces. The instrument was inserted laparoscopically into the proximal hematocolpos. Two balloon catheters, one for drainage and one for traction, were threaded over the inserter...

BACKGROUND: The conventional treatment for idiopathic intracranial hypertension involves weight loss, steroids, diuretics, and/or serial lumbar punctures; however, if the symptoms persist or worsen, surgical intervention is recommended. Surgical options include cerebrospinal fluid diversion procedures, such as ventriculoperitoneal and lumboperitoneal shunts, and optic nerve decompression with nerve sheath fenestration. The latter can be carried out using an endoscopic approach, but the outcomes of this technique have not been firmly established...

OBJECTIVES: There is no consensus or theoretical explanation regarding the optimal location for the fenestration during the Fontan operation. We investigated the impact of the location of the fenestration on Fontan haemodynamics using a three-dimensional Fontan model in various physiological conditions. METHODS: A three-dimensional Fontan model was constructed on the basis of CT images, and a 4-mm-diameter fenestration was located between the extracardiac Fontan conduit and the right atrium at three positions: superior, middle, and inferior part of the conduit...

A 77-year-old male patient presented with a symptomatic, 66-mm pararenal aortic aneurysm. The patient was classified as unsuitable for open surgery due to significant comorbidities. Fenestrated or branched endografts were contraindicated due to the poor iliac access (6 mm diameter). A double Nellix with chimney endovascular aneurysm sealing (ChEVAS) technique was selected to exclude the pararenal aortic aneurysm and to preserve renal arteries and the superior mesenteric artery. Technical preplanning considered the ideal proximal landing zone to be close to the origin of the almost occluded celiac trunk and the distal common iliac arteries as the ideal distal landing zone...
