Experimental methods that allow examination of the intact vascular network of large organs, such as the human placenta are limited, preventing adequate comparison of normal and abnormal vascular development in pregnancy disease. Our aims were (i) to devise an effective technique for three-dimensional analyses of human placental vessels; (ii) demonstrate the utility of the technique in the comparison of placental vessel networks in normal and fetal growth restriction (FGR) complicated pregnancies. Radiopaque plastic vessel networks of normal and FGR placentas (n = 12/group) were created by filling the vessels with resin and corroding the surrounding tissues...

Primary hyperparathyroidism (pHPT) causes hypercalcemia. The treatment for pHPT is surgical dissection of the hyperfunctioning parathyroid gland. Lower rates of hypocalcemia and recurrent laryngeal nerve injury imply that minimally invasive parathyroidectomy (MIP) is safer than bilateral neck resection. Current trends in MIP use can be inferred only by reference to preoperative localization studies. Noninvasive imaging studies (typically preoperative localization studies) show good detection rates of hyperfunctioning glands; however, there have also been cases of nonlocalization or discordant results...

Surgical resection represents the mainstay treatment and only potentially curative option for gastric carcinoma, and is increasingly performed laparoscopically. Furthermore, other tumours and selected cases of non-malignant disorders of the stomach may require partial or total gastrectomy. Often performed in elderly patients, gastric resection remains a challenging procedure, with significant morbidity (14-43% complication rate) and non-negligible postoperative mortality (approximately 3%). This paper provides an overview of contemporary surgical techniques for non-bariatric gastric resection, reviews and illustrates the expected postoperative imaging appearances, common and unusual complications after partial and total gastrectomy...

OBJECTIVE: To describe the prenatal imaging features enabling diagnosis of developmental venous anomalies (DVA). METHODS: Four fetuses with unexplained persistent echogenic parenchymal brain lesions were studied. The evaluation included dedicated neurosonography, fetal MRI, serology for intrauterine infection, screening for coagulation abnormalities, and chromosomal microarray. Postnatal neurodevelopmental follow-up or autopsy results were assessed. RESULTS: DVA presented as very slowly growing echogenic brain lesions without cystic components, calcifications, or structural changes on otherwise normal neurosonographic scans performed at 2- to 3-week intervals...

OBJECTIVE: Monocyte chemoattractant protein 1 (MCP-1) is a chemokine responsible for monocyte, basophil, and T-lymphocyte attraction. Polymorphism rs1024611 located in the regulatory region of the MCP1 gene has previously been shown to be associated with increased MCP-1 production. In our study, we aimed to examine the association of rs1024611 with the risk of primary varicose veins (PVVs) of lower extremities. METHODS: The case group comprised 470 patients with PVVs, and the control group included 269 individuals without a history of chronic venous disease...

BACKGROUND: The Effect of Surgery and Compression on Healing and Recurrence (ESCHAR) trial previously reported that patients with venous leg ulcers treated with saphenous stripping experienced a significantly reduced incidence of ulcer recurrence compared with patients treated with compression therapy. Most patients with leg ulcers and saphenous insufficiency are currently treated with endovenous thermal ablation (EVTA), but little information is available on the long-term results after EVTA in Clinical, Etiology, Anatomy, and Pathophysiology (CEAP) clinical class 5 (C5) and class 6 (C6) patients...

Tissue defect reconstruction using radial forearm free flap (RFFF) is a common surgical technique whose success or failure is mainly dependent on venous drainage. RFFF has two major venous outflow systems, superficial and deep vein. Drainage methods include combining both systems or using one alone. This review aims to recapitulate the vascular anatomy and network of RFFF as well as shed light on deep vein as a reliable venous drainage system. We also discuss basic evidence for and advantages of single microanastomosis with coalesced vein to overcome technical difficulties associated with the deep vein system...

The data concerning the anatomy of perforant veins of the foot can by no means be referred to as insufficiently known. At the same time, these descriptions are encountered rather rarely in the educational-and-methodical literature. To a certain degree, this may be explained by low pathogenetic significance of perforant veins of the foot; however, these data are required for the surgeon in carrying out both standard phlebectomy and sclerotherapy of subcutaneous varicose veins, especially if the zone of surgical intervention is situated immediately on the foot...

The evaluation of venous drainage patterns prior to surgery for skull base meningioma is important owing to their deep location and the vulnerability of surrounding vascular structures. In recent years, the microsurgical skull base approach has matured as a surgical technique, making it an important option for reducing complications related to skull base meningioma surgery. In addition, knowledge of the venous anatomy can prevent venous drainage route disturbance and potentially life-threatening complications...

A 44-year-old man presented with swelling in the left parotid region. The swelling was firm and Fine Needle Aspiration Cytology report proved pleomorphic adenoma. In the CT scan, the tumour was confined to the superficial lobe of parotid. So, left superficial parotidectomy was planned. Modified Wilson Blair's incision was used. On course of identifying the facial nerve, a large calibre vein was identified running vertically through the parotid substance. Assuming it as retromandibular vein, further dissection was carried out more meticulously...

In the United States, venous thromboembolism is associated with high mortality and morbidity affecting as many as 900 000 people (1-2 per 1000) each year. Estimates suggest that 60 000 to 100 000 Americans die of deep venous thrombosis/pulmonary embolism and 10% to 30% die within 1 month of diagnosis, with sudden death being the first symptom in approximately 25% of population with pulmonary embolism. One-half of the patients with deep venous thrombosis will have postthrombotic syndrome, which includes swelling, pain, discoloration, and scaling in the affected limb...

Dural arteriovenous fistulae are high flow, low resistance intracranial vascular malformations defined by an aberrant connection between an artery and dural vein or sinus. Symptomatology and presentation are highly dependent on location, generally categorized as supratentorial, tentorial, or infratentorial, and consist primarily of sequelae secondary to local venous hypertension, insufficiency, and cortical venous reflux. Surgery is generally reserved for high risk or persistently symptomatic lesions that are unamenable or unresponsive to endovascular therapy...

BACKGROUND: Real-time magnetic resonance imaging (MRI) visualization during stereotactic needle biopsies affords several valuable benefits to the neurosurgeon, including the opportunity to visually confirm the biopsy site at the time of surgery. Until now, reported experiences with this technique have been limited to the setting of intraoperative MRI or dedicated procedural MRI suites with modified ventilation systems. OBJECTIVE: To describe our experience with 11 consecutive patients who underwent real-time MRI-guided biopsy performed using SmartFrame® stereotaxis (MRI Interventions, Irvine, California) in the setting of a conventional diagnostic MRI suite...

Given the widespread use of transjugular intrahepatic portosystemic shunt (TIPS) creation for the treatment of portal hypertensive complications, a working knowledge of portal venous anatomy is critical for interventional radiologists. The right portal vein - which is most commonly accessed during TIPS - is subject to various anatomic variants that may potentially impact procedure success. This pictorial essay characterizes the anatomic patterns of the right portal vein branching in terms of type and frequency based on case series review...
