INTRODUCTION: A growing number of surgeons perform lymph node transfers for the treatment of lymphedema. When harvesting a vascularized lymph node groin flap (VGLNF) one of the major concerns is the potential risk of iatrogenic lymphedema of the donor-site. This article helps understanding of the lymph node distribution of the groin in order to minimize this risk. MATERIALS AND METHODS: Fifty consecutive patients undergoing abdominal mapping by multi-detector CT scanner were included and 100 groins analyzed...

In the field of veterinary anatomy, most of the specimens used in practical sessions are perfused with fixatives. Thus, they can be used for a longer time, reducing the number of animals for educational purposes. Formalin is the most commonly used fixative, consisting of a 37% formaldehyde solution. However, formaldehyde is a powerful irritant of the eyes and airways and is considered carcinogenic, causing nasopharyngeal cancer in exposed workers and professionals. In the present study, we explored an alternative method to avoid the use of formaldehyde in specimens used for gross anatomy practical sessions...

OBJECTIVE: Focused ultrasound (FUS) is rapidly gaining clinical acceptance for several target tissues in the human body. Yet, treating liver targets is not clinically applied due to a high complexity of the procedure (noninvasiveness, target motion, complex anatomy, blood cooling effects, shielding by ribs, and limited image-based monitoring). To reduce the complexity, numerical FUS simulations can be utilized for both treatment planning and execution. These use-cases demand highly accurate and computationally efficient simulations...

The majority of the ruptured abdominal aortic aneurysms today is treated endovascularly. In cases with short aneurysm neck, chimney technique can be used to extend landing zone in emergency setting. Additionally, the repositioning ability of C3 delivery system (Gore & Associates) allows better positioning in cases with challenging anatomy. In our experience, proximal reposition of partially deployed device can be problematic in some patients. We present a case of endovascular repair of ruptured abdominal aortic aneurysm using chimney technique where proximal reposition was achieved by snaring the aortic device via axillary access...

Gastric volvulus (GV) is characterized by the abnormal rotation of a portion of the stomach around a horizontal or vertical axis that can cause obstruction, vascular disorder and even strangulation, and may evolve into necrosis or even perforation. It can be classified according to its aetiology into primary or secondary GV, according to its anatomy into axial organ or into axial mesenteric GV, and according to its presentation into chronic or acute GV. Both types of volvulus require treatment; however, in spite of the classic treatment being open surgery, there is no standard treatment, nor is there consensus on the alternative of choice at present...

Hydrocephalus is usually treated by placement of a ventriculo-peritoneal (VP) shunt. Distal VP shunt failure is a common complication of this procedure, especially in the paediatric population. Distal shunt revisions are often made more technically difficult by challenging abdominal anatomy. In this technical note, we describe a simple technique utilizing tenting sutures and the previous shunt tract for placement of the distal abdominal catheter accurately into the peritoneal space during distal shunt revision...

OBJECTIVES: Surgical restoration of pelvic floor anatomy in pelvic organ prolapse (POP) should avoid extensive areas that may injure healthy tissues and lead to scar fibrosis producing dysfunctional rigidity. Laparoscopic sacrocolpopexy corrects POP by lifting pelvic elements with a minimally invasive procedure.Various current strategies and approaches make it a diverse procedure. METHODS: We performed a bibliographic review on the published experience about abdominal sacrocolpopexy over the last 20 years...

Ever since the US Food and Drug Administration approval of the use of da Vinci surgical systems (Intuitive Surgical Inc., Sunnyvale, California) in gynaecology in 2005, robot-assisted surgery has been widely adopted in different countries. Some of the applications in benign and oncological gynaecology include myomectomy, sacrocolpopexy, tubal anastomosis, simple hysterectomy, radical hysterectomy, radical trachelectomy, pelvic and/or para-aortic lymphadenectomy and even debulking surgery for ovarian cancer and pelvic exenteration for recurrent cervical and vaginal cancer...

OBJECTIVES: Endovascular aneurysm repair (EVAR) is considered the treatment of choice for abdominal aortic aneurysms with suitable anatomy. In order to improve radiation safety, European Directive (2013/59) requires member states to implement diagnostic reference levels (DRLs) in radio-diagnostic and interventional procedures. This study aimed to determine local DRLs for EVAR across five European centres and identify an interim European DRL, which currently remains unestablished. METHODS: Retrospective data was collected for 180 standard EVARs performed between January 2014 and July 2015 from five specialist centres in Ireland (n=2) and Italy (n=3)...

Endoscopic ultrasound (EUS) has been increasingly used for the diagnosis and staging of pancreatic cancer. It has recently become the modality of choice in assessing pancreatic lesions overcoming other traditional modalities. Typically lesions located at the tail of the pancreas are best accessed through the stomach. We present a patient with pancreatic tail mass occurring in the setting of a large hiatal hernia, intrathoracic stomach, and severe lumbar levoscoliosis. Due to altered anatomy and extensive vascular connections of the mass, any surgical or radiological intervention was considered high risk for the patient...

OBJECTIVE/BACKGROUND: Absence of an adequate iliac seal rarely represents an absolute contraindication to endovascular abdominal aortic aneurysm repair. Iliac branch devices (IBD) are increasingly used in patients with extensive aorto-iliac aneurysmal disease, but few data are available on the long-term results of these procedures. METHODS: Between 2006 and 2016, 157 consecutive IBD procedures performed at a single centre were entered into a prospective database...

BACKGROUND: Sphincter of Oddi dysfunction (SOD) is thought to be a cause of chronic abdominal pain post Roux-en-Y gastric bypass, and current practice of performing endoscopic retrograde cholangiopancreatography (ERCP) with or without sphincterotomy is not supported by evidence. In addition to the complexity and risks of the procedure in patients with Roux-en-Y anatomy, the outcomes are uncertain and debatable. We performed a retrospective review and analysis of post-gastric bypass patients who had undergone ERCP with sphincterotomy to determine the effectiveness in patients with suspected SOD...

Aortocaval fistula (ACF) is a rare complication. Endovascular repair is an option for this fatal condition. However, endoleak and persistent fistula may occur and lead to technical failure. We performed endovascular repair for 3 cases of challenging ACF with hostile anatomy. Patient 1 was an 80-year-old man who complained of abdominal distension and lower limb edema for 15 days. He had renal and cardiac dysfunction. Computed tomography angiography (CTA) showed an ACF and extreme tortuosity of right iliac artery...

The large size of some retroperitoneal tumors and the complex anatomy of the retroperitoneal structures often require en bloc resection of contiguous organs and, sometimes, resection of critical vascular structures. Vascular reconstructive techniques allow reconstruction of major vascular structures, and autologous vein grafting is the preferred option. Although great saphenous vein can be used in select cases, other options must be explored in cases of caliber mismatch between saphenous vein and native vessel...
