As abdominally-based free flaps for breast reconstruction continue to evolve, significant effort has been invested in minimizing donor-site morbidity. The impact on the donor-site remains a prevailing principle for breast reconstruction, and thus must be adequately reflected when classifying what is left behind following flap harvest. Although successful in describing the type of flap harvested, the existing nomenclature falls short of incorporating certain critical variables, such as degree of muscular preservation, fascial involvement, mesh implantation, and segmental nerve anatomy...

BACKGROUND: Pancreatic leaks occur as a complication of upper gastrointestinal surgery, acute pancreatitis, or abdominal trauma. Pancreatic fistulas and leaks are primarily managed conservatively. Overall, conservative measures are successful in more than half of cases. Whenever conservative treatment is not efficient, surgery is usually considered the treatment of choice. Nowadays however, endoscopic treatment is being increasingly considered and employed in many cases, as a surgery sparing intervention...

A variant anatomy of the hepatic vasculature has a clinically significant role in hepatobiliary transplantation, resection, tumour embolisation as well as in extrahepatic abdominal surgeries involving the stomach, pancreas or gall bladder. During routine cadaveric dissection, we observed a case of unusually small calibre hepatic artery proper. An accessory hepatic artery was seen emerging from the superior mesenteric artery to the right hepatic lobe along with an accessory hepatic vein from the right hepatic lobe that drained directly into the inferior vena cava...

INTRODUCTION: Liver is the largest abdominal organ located in right hypochondrium, epigastrium and left hypochondrium in upper abdominal cavity. Although the segmental anatomy of the liver has been extensively researched, very few studies have dealt with surface variations of the liver. The major fissures are important landmarks for interpreting the lobar anatomy and locating the liver lesions. AIM: To determine gross anatomical variations of liver and their clinical and surgical implications...

Teleost vertebral centra are often similar in size and shape, but vertebral-associated elements, i.e. neural arches, haemal arches and ribs, show regional differences. Here we examine how the presence, absence and specific anatomical and histological characters of vertebral centra-associated elements can be used to define vertebral column regions in juvenile Chinook salmon (Oncorhynchus tshawytscha). To investigate if the presence of regions within the vertebral column is independent of temperature, animals raised at 8 and 12 °C were studied at 1400 and 1530 degreedays, in the freshwater phase of the life cycle...

PURPOSE: We report the case of a thoracic endograft used to achieve exclusion of a ruptured proximal paranastomotic abdominal aortic aneurysm (PAAA) as a consequence of aortic ballooning. CASE REPORT: A type I proximal endoleak was evidenced following endovascular repair of a PAAA with an aortic cuff. The leak was treated with ballooning, which caused distal aortic rupture. A thoracic endograft was deployed inside the cuff, achieving complete exclusion. At 1 year, there are no signs of migration or endoleak with complete PAAA thrombosis, according to computed tomographic angiography...

Iliac arterial disease, unfavorable anatomy, and prior stenting all pose challenges to access in endovascular abdominal aortic repair (EVAR) and thoracic aortic repair (TEVAR). Iliac access injury during T/EVAR may lead to rupture, dissection, thrombosis, or distal ischemia. Some have advocated iliac stent prior to T/EVAR in patients with suboptimal iliac access. The rate of complication and iliac stent migration during subsequent T/EVAR is undocumented. This case report describes a unique instance of self expanding iliac stent migration during TEVAR which pinched the thoracic aortic endograft causing functional aortic coarctation...

INTRODUCTION: Recent literature has reported an association between maternal supine sleep position and stillbirth during late pregnancy. In this position the gravid uterus almost completely obstructs the inferior vena cava. A small number of women experience supine hypotension, thought to be due in part to inadequate collateral venous circulation. The aim of this paper is to review the literature describing the anatomy of the collateral venous system and in particular the azygos system, the abdominal portion of which has not been well studied...

PURPOSE: This work investigated whether the Bragg peak (BP) positions of proton beams can be modulated to produce uniform doses and cover a tumor under the magnetic fields inside cancer patients, and whether magnetic field modulated proton therapy (MMPT) is effective in vital organ protection. METHODS: The authors initially constructed an ideal water phantom comprising a central tumor surrounded by cuboid organ regions using GEANT4. Second, we designed the proton beams passing through the gap between two adjacent organ regions during beam configuration...

Abdominal wall hernias are one of the most common and long-standing surgical applications for biomaterials engineering. Yet, despite over 50 years of standard use of hernia repair materials, revision surgery is still required in nearly one third of patients due to hernia recurrence. To date, hernia mesh designs have focused on maximizing tensile strength to prevent structural failure of the implant. However, most recurrences occur at the biomaterial-tissue interface. There is a fundamental gap in understanding the degree to which a mechanical mismatch between hernia repair materials and host tissue contributes to failure at this interface...

PURPOSE: Cone shape neck is regarded as non-instruction for use (IFU) in most commercial stent graft. However, in real practice, liberal application of endovascular aneurysm repair (EVAR) for outside of IFU happens. We investigate non-adherence to conical neck anatomy in terms of early aneurysmal exclusion results. MATERIALS AND METHODS: From January 2010 to December 2013, 105 patients with abdominal aortic aneurysm (AAA) underwent EVAR in Daegu Catholic University Medical Center...

Endovascular approaches to the aortic arch are challenged by unique anatomy and physiology of this area. Simple application of conventional endovascular technology and technique for abdominal or descending thoracic aortic disease to the aortic arch is insufficient to achieve effective and durable repairs. Appreciation of these challenges has led to developments in endovascular technology as well as complex strategies to deal with individual patient anatomy that hold the potential for continued improved outcomes in both the short and the long term...

Despite improvements in endograft design, operator skills, and patient selection, late endovascular abdominal aortic aneurysm repair (EVAR) associated complications and need for reinterventions remains the Achilles heel. These complications erode the early benefit over open aneurysm repair during long-term follow-up. The recently introduced endovascular aneurysm sealing (EVAS) is an innovative technology with the intention to lower these EVAR related complications. Areas covered: In this review the EVAS technique, indications, and possible applications, will be discussed, as well as a critical appraisal of clinical outcomes...

Six consecutive patients (3 men; mean age, 63 ± 14 years; age range, 38-81 years) with infrarenal abdominal aortic stenosis underwent unilateral or bilateral transradial approach for stenting of the aortic lesion. In 4 cases, isolated aortic stenting was performed through single transradial approach (in 2 cases with precise alignment to the proximal end of previously deployed iliac stents), whereas in the other 2 cases bilateral transradial approach was used for aortic stenting followed by bilateral stenting of the proximal iliac arteries...

The anatomy of the human being has not changed. However, technical developments in operating materials and methods call for improvements in surgical procedures as well as the management of complications. A fundamental distinction between any operating method and laparoscopy is that, in the latter, the initial entry is usually performed in blind fashion. Blind entry may result in vessel or organ damage, especially in patients who have undergone previous surgery. One of the difficulties associated with the entry is that the damage may not be identified immediately and then necessitate major abdominal repair...
