Latex is a complex plant secretion with both ecological and economic importance. There is little information currently available on the cytological aspects of the ontogenesis of anastomosed laticifers, the ducts originating through the lysis of adjacent cell walls. Hancornia speciosa is a tree typical of the Cerrado (neotropical savanna) biome. Its latex has medicinal value and is also used to produce rubber. The ontogenesis of its laticifers and the process of latex synthesis are described here. Structural, cytochemical, and ultrastructural analyses of the stem apex and phytochemical analyses of the latex were performed...

BACKGROUND: Reduced-port laparoscopic gastrectomy further minimizes the invasiveness of laparoscopic gastrectomy, thereby improving patient quality of life. However, suboptimal ergonomics and visualization are challenges to performing reduced-port laparoscopy. As the application of a robotic surgical system may help overcome these challenges, the present study was performed to evaluate the short-term outcomes of reduced-port totally robotic distal subtotal gastrectomy. METHOD: An initial 40 consecutive gastric cancer patients treated with reduced-port totally robotic distal subtotal gastrectomy with lymph node dissection from February 2016 to February 2017 were retrospectively reviewed...

Introduction Anatomical studies on human cadavers have established anastomoses between laryngeal nerves. However, we need to functionally identify motor communication via these anastomoses between the recurrent laryngeal nerve (RLN) and the external branch of the superior laryngeal nerve (EBSLN) in living bodies. We aim to establish motor interconnections using intraoperative nerve monitoring (IONM). Methods IONM of 112 EBSLNs and RLNs in 62 thyroidectomy cases was used to establish motor functions of laryngeal nerves...

BACKGROUND: Many pancreatic anastomoses have been proposed to reduce the incidence of postoperative pancreatic fistula (POPF) after pancreatoduodenectomy, but a complete overview is lacking. This systematic review and meta-analysis aims to provide an online overview of all pancreatic anastomosis techniques and to evaluate the incidence of clinically relevant POPF in randomized controlled trials (RCTs). METHODS: A literature search was performed to December 2017...

Venous malformations are the most common slow-flow vascular malformations; they are not prone to volume decrease over time and invasive treatment is usually required. There are two main techniques to address the definitive therapy of these lesions: sclerotherapy and surgical excision, each with its own advantages and disadvantages. We report the case of a 56 year-old man who came to our attention with persistent pain after multiple unsuccessful attempts to treat a large venous malformation located in the area of the right knee...

Management of Type 1A endoleaks can be challenging. In the endovascular era, this condition is expected to become more frequent. Conventionally, surgical explant of the endograft remains the "last resort" surgical treatment when all endovascular or other open options are exhausted. Endograft removal is a difficult and morbid procedure. An alternative technique is described that involves cinching the endograft following disengagement of the proximal fixation hooks. The endograft is re-deployed within a prosthetic aortic replacement graft with an overlapping zone...

Intestinal transplant (IT) is one of the least common forms of organ transplant but is increasing both in volume of cases and number of centers performing intestinal transplants, with the busiest centers in North America and Europe. IT can be performed in isolation or as part of a multivisceral transplant (MVT). Intestinal failure either in the form of short gut syndrome or functional bowel problems is the primary indication for IT. The normal post-surgical anatomy can be variable due to both recipient anatomy in regard to amount of residual bowel and status of native vasculature as well as whether the transplant is isolated or part of an multivisceral transplant...

INTRODUCTION: Posterior spinal arteries (PSAs) arise from the vertebral (VA) or posterior inferior cerebellar (PICA) artery. We identified variations in their origins and their anastomosis with the first posterior radiculomedullary branches in human spinal cords. MATERIALS AND METHODS: Spinal cords from male and female cadavers (n = 30) were injected with colored latex through the vertebral, ascending cervical, costocervical trunk and segmental arteries. Specimens were fixed in formalin and the spinal arteries were dissected under a surgical microscope...

Distal middle cerebral artery (MCA) aneurysms often have non-saccular morphology and cannot be clipped, requiring revascularization and trapping instead. Combination bypasses are needed when 2 arteries exit the aneurysm, and extracranial-intracranial and intracranial-intracranial bypasses can be used. This video demonstrates a combination bypass used to treat a previously stented distal MCA aneurysm with both a superficial temporal artery (STA)-to-MCA bypass and an M2-to-M2 reanastomosis. This 56-yr-old man presented with distal left-sided MCA aneurysm 2 years earlier and attempted stent-assisted coiling was aborted after the aneurysm was perforated with stenting alone...

BACKGROUND: Dual venous drainage for anterolateral thigh flaps has been proposed to protect against flap-related complications in head and neck applications. Here we report our experience with single vs dual venous anastomosis during lower extremity free-tissue transfer. METHODS: All free anterolateral thigh flaps for lower extremity reconstruction from 2011 to 2017 were retrospectively reviewed. An algorithm was used to determine the type and number of venous anastomoses, emphasizing patient anatomy, venous quality, and size match...

We present the unique case of a 15-month-old male born with biliary atresia and situs inversus totalis and disrupted inferior vena cava who underwent a successful liver transplantation. The patient had previously undergone a failed Kasai procedure and presented with persistent hyperbilirubinemia. The patient was transplanted with a left lateral segment donor having standard arterial anatomy. Technical considerations included identifying completely replaced arterial anatomy in the recipient from the superior mesenteric artery and creating a branch patch between the gastroduodenal artery and HA, anastomosing the donor left hepatic vein to confluences of the donor left, middle, and right hepatic veins, using a "lazy-S" configuration of portal vein anastomosis, and suspending the allograft to the abdominal wall...

Introduction: Carbon dioxide laser coagulation during transoral laser microsurgery (TLM) for laryngeal cancer allows control of bleeding from vessels smaller than 0.5 mm. Therefore, larger arteries and veins must be carefully managed by clipping and/or monopolar cautery. The aim of this paper is to detail endolaryngeal vascular anatomy and identify areas of possible bleeding during TLM. Methods: We performed an anatomical study on a series of 11 fresh-frozen human cadavers...

OBJECTIVES: The authors report their experience with atrial fibrillation (AF) rates and ablation findings in lung transplant recipients. BACKGROUND: Pulmonary venous (PV) conduction recovery accounts for most failed atrial fibrillation (AF) catheter ablation procedures. Lung transplantation involves full surgical resection and replacement of the recipient's PVs with donor's PVs, which may represent the ultimate PV ablation. METHODS: They followed 755 consecutive lung transplant recipients categorized based on transplant status (unilateral vs...

BACKGROUND: In pharyngoesophageal reconstruction, we transferred a long jejunum flap containing multiple pedicles to achieve a 100% flap survival rate, and used the redundant mesentery to cover important tissues and fill in the dead space to reduce common postoperative complications, such as surgical site infections and fistula formation. METHODS: A total of 243 jejunal flap transfers with multiple vascular anastomoses were reviewed to examine flap survival and rates of early postoperative complications, such as surgical site infections and fistula formation, perioperative mortality, and donor site morbidity...

We report a case of chronic dissecting thoracoabdominal aneurysm with intraoperative retrograde aortic dissection and rupture at proximal descending aorta, which was successfully treated by echoguided stent-graft insertion. An 82-year old male underwent thoracoabdominal aortic replacement for dilatation of infra-diaphragmatic aorta. Under F-F bypass, his thoracoabdominal aorta was replaced by a Dacron graft with 4-branches. After he weaned from F-F bypass, we found massive bleeding from proximal descending aorta...

The patient was a 66 year-old male. Computed tomography (CT) angiography showed a huge aneurysm(120 mm) in the aortic arch and chronic type B aortic dissection(45 mm) in the descending aorta. Echocardiography showed patent ductus arteriosus( PDA). Because of pulmonary hypertension due to PDA, it was considered unacceptable to put him under general anesthesia twice. We performed thoracic endovascular aortic repair (TEVAR) via the ascending aorta and total arch replacement (TAR) simultaneously to prevent paraplegia...

OBJECTIVE: The effect of aortic clamping strategy on short-term stroke during proximal graft construction for coronary artery bypass grafting (CABG) remains undefined. The aim of this study was to test the hypothesis that partial occluding clamp (POC) technique does not increase incidence of postoperative stroke compared with single clamp (SC) technique for performing proximal coronary anastomoses. METHODS: We identified 52,611 patients who underwent on-pump CABG in the Society of Thoracic Surgeons Adult Cardiac Surgery Database from July 1, 2014 to March 31, 2015...

BACKGROUND: The incidence of metachronous esophageal squamous cell cancer (ESCC) after head and neck cancer (HNC) and in elderly patients has increased. Both elderly ESCC patients and ESCC patients after HNC surgery are at potential risk for dysphagia, and for the latter, surgery in the neck is difficult. An intrathoracic anastomosis that bypasses the cervical procedure is preferable to preserve swallowing function and reduce surgical risk. In gastrectomized patients, because the stomach cannot be used as a substitute, securing graft blood supply is critical, but microvascular anastomosis cannot be easily added in procedures for intrathoracic posterior mediastinal reconstruction...
