A mycotic aneurysm that also involves the visceral arteries is a life-threatening condition. Surgical management typically consists of débridement and in situ repair with a Dacron graft and reimplantation of the involved visceral branches. We report a rare case of a mycotic saccular thoracoabdominal aortic aneurysm involving the celiac artery, with Streptococcus pneumoniae as the responsible organism. Successful repair of the aneurysm and concomitant revascularization of the celiac artery were achieved.

BACKGROUND: Compared to open thoracoabdominal aortic aneurysm (TAAA) repair, hybrid repair is thought to be less invasive with better perioperative outcomes. Due to the extent of the operation and long recovery period, studying perioperative results may not be sufficient for evaluation of the true treatment effect. The aim of this study is to evaluate 1-year mortality and morbidity in patients with TAAA undergoing hybrid repair. METHODS: In a retrospective cohort study, all medical records of patients undergoing hybrid repair for TAAA at the Erasmus University Medical Center between January 2007 and January 2015 were studied...

A 10 week old female intact Staffordshire terrier was presented with a total of five congenital cardio-thoracic vascular anomalies consisting of a patent ductus arteriosus (PDA) with an aneurysmic dilation, pulmonic stenosis, persistent right aortic arch, aberrant left subclavian artery and persistent left cranial vena cava. These abnormalities were identified with a combination of echocardiogram and computed tomography angiography (CTA). The abnormalities were associated with esophageal entrapment, regurgitation, and volume overload of the left heart with left atrial and ventricular enlargement...

Introduction: In the treatment of complex aneurysms, debranching is an extra-anatomical revascularization of visceral arteries followed by endograft coverage of the thoracoabdominal aorta. It eliminates the need for a thoracotomy and aortic clamping, but requires the performance of several technically demanding visceral anastomosis. In 2008, Lachat described visceral revascularization with the use of a sutureless distal anastomosis, performed by the telescoping of an endograft in the visceral branch, named VORTEC (Viabahn Open Revascularization TEChnique)...

BACKGROUND: The indications and strategies for treatment of patent ductus arteriosus (PDA) are controversial, and the safety and long-term benefits of surgical PDA closure remain uncertain. The aim of this study was to compare the lung function of very low birth weight (VLBW) infants after successful PDA treatment with a cyclooxygenase inhibitor or secondary surgical ligation. METHODS: A total of 114 VLBW infants (birth weight < 1500 g), including 94 infants (82%) with a birth weight < 1000 g, who received treatment for hemodynamically significant PDA (hsPDA), were examined at a median postmenstrual age of 48 weeks...

PURPOSE: For the image guided radiation therapy (IGRT), the shadows caused by the construction of the treatment couch top adversely affect the visual evaluation. Therefore, we developed the new imaging filter in order to remove the shadows. The performance of the new filter was evaluated using the clinical images. METHODS: The new filter was composed of the band-pass filter (BPF) weighted by the k factor and the low-pass filter (LPF). In the frequency region, the stop bandwidth were 8...

The primary risks associated with thoracoabdominal aortic aneurysm (TAAA) repair-namely operative death, paraplegia, and renal failure necessitating dialysis-are commonly related to the distal ischemia that occurs during aortic clamping and the disruption of vital branching arteries. Our technique for open TAAA repair has evolved over the course of 3 decades, from the unheparinized, simple "clamp-and-sew" approach learned directly from E. Stanley Crawford himself to a contemporary, multimodal strategy that uses an array of surgical adjuncts...

OBJECTIVES: We aimed to develop a simple, reliable, and timesaving technique for the therapy of thoracoabdominal aortic (TAA) aneurysms that are not suitable for endovascular repair. METHODS: In this pilot study, we sought to combine the advantages of classic open vascular procedure with the use of endoscopic surgical tools and small skin incisions to develop a minimally invasive approach for TAA replacement. The following procedures were used: endoscopic exposure and closure of the lower intercostal arteries; small posterolateral thoracotomy and left retroperitoneal incisions to expose the anastomotic regions of the aorta; partial anticoagulation; passive bypass and sequential aortic clamping; tunnelling of the graft through the native aortic lumen (endoaneurysmorrhaphy) and open performance of vascular anastomosis...

PURPOSE: In the present prospective randomized controlled study, we compared the feasibility and effectiveness of our modified thoracoabdominal approach to anterior thoracolumbar spine surgery without cutting open the costal portion of diaphragm (extradiaphragmatic approach) with the traditional transdiaphragmatic thoracoabdominal approach. The traditional combined thoracoabdominal approach in anterior thoracolumbar surgery for spine tuberculosis is effective but seriously damages the diaphragm and causes various lung complications...

BACKGROUND: An objective method to evaluate thoracoabdominal movement is needed in daily clinical practice to detect patients at risk of hypoventilation and to allow for timely interventions in neuromuscular diseases. The clinical feasibility, reliability, and validity of a newly developed method for quantifying respiratory movement using fiber grating sensors, called the Respiratory Movement Evaluation Tool (RMET), was evaluated. METHODS: The time needed to measure respiratory movement and the usability of the measurement were determined by 5 clinicians using the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST) 2...

BACKGROUND: Recovering premature infants are at risk for hypoxemia and lack of synchrony between their rib cage and abdomen due to airflow obstruction and poor respiratory compliance. Thoracoabdominal asynchrony (TAA) is a useful marker of resistive and elastic lung properties. Whether TAA predicts oxygenation is unknown. OBJECTIVES: We investigated oxyhemoglobin saturation (SpO2%) and TAA (phase angle, φ) in preterm infants with/without high-humidity nasal cannula (HHNC)...

BACKGROUND: Innate immune responses activated through myeloid cells contribute to the initiation, progression, and complications of atherosclerosis in experimental models. However, the critical upstream pathways that link innate immune activation to foam cell formation are still poorly identified. OBJECTIVES: This study sought to investigate the hypothesis that activation of the triggering receptor expressed on myeloid cells (TREM-1) plays a determinant role in macrophage atherogenic responses...

Shock thyroid is a part of the hypovolemic shock complex, which is a constellation of secondary computed tomographic (CT) findings that are observed in patients with hypovolemic shock. However, to the best of our knowledge, there has only been a single report on this condition, which described three cases associated with significant thoracoabdominal trauma. Here, we report four patients with profound hypotension who exhibited similar CT findings as those described in the initial report on shock thyroid, but with a more diverse clinical spectrum...

Ectopia cordis (EC) is a rare congenital anomaly often associated with congenital heart disease (CHD). There is a lack of contemporary information on EC diagnosed prenatally. We sought to combine the experiences of two regional referral centers in order to evaluate current outcomes for EC. Clinical, echocardiographic features and perinatal outcomes of fetuses with EC managed at two large cardiac centers from 1995 to 2014 were retrospectively reviewed. Seventeen fetuses with EC were diagnosed at a median gestational age of 23 weeks (range 17-36)...

A 53-year-old man arrived at the trauma center with a steel bar penetrating from the epigastrium to the right scapula. He was hypotensive and hypoxic, and immediate resuscitation and basic evaluation were performed. An emergency operation was performed due to an unstable hemodynamic state. Multiple injuries were confirmed in the right lower lobe, posterior chest wall, diaphragm, and liver lateral segment. Right lower lobectomy and liver lateral sectionectomy were performed following removal of the bar. The patient recovered without additional hemorrhage after the surgery, and was transferred to a rehabilitation institution with periodic follow-up...

OBJECTIVES: Early experience with Loeys-Dietz syndrome (LDS) suggested an aggressive aortopathy with high risk of aneurysm dissection and rupture at young ages and at smaller aortic diameters than in other connective tissue disorders. We reviewed our experience with LDS to re-examine our indications and outcomes of surgical management. METHODS: We reviewed all patients with a diagnosis of LDS who underwent cardiovascular surgery at our institution. The primary endpoint was mortality, and secondary endpoints included postoperative complications and need for reintervention...
