Background Lymphangioleiomyomatosis (LAM) is a rare disease involving the bronchi, lymphatic vessels, and veins. However, there are few reports about lymphatic vessel abnormalities associated with LAM. Purpose To evaluate computed tomography (CT) lymphangiography findings in cases of LAM, especially lymphatic vessel abnormalities. Material and Methods Twenty-seven patients with LAM underwent direct lymphangiography (DLG), followed by a post-procedural thoracoabdominal CT examination. Results All 27 patients were diagnosed with LAM, including 25 (93%) with chylothorax, eight (30%) with chyloperitoneum, seven (26%) with chylous fluid in the chest and abdomen, and one (4%) with lower-limb lymphedema...

The antiphospholipid antibody syndrome is defined by the presence of antiphospholipid antibodies in patients with recurrent venous or arterial thromboembolism (1). SAPHO syndrome is a rare disease, characterized by specific clinical manifestations of synovitis, acne pustulosis, hyperostosis, and osteitis. It is a disease that manifests with a combination of osseous and articular manifestations associated with skin lesions (2). Venous thrombosis complicating SAPHO syndrome seems to be uncommon with an unclear pathogenesis (3-9)...

PURPOSE: To perform a synthesis of articles addressing the role of stretching on roots in the pathophysiology of radiculopathy. METHODS: Review of relevant articles on this topic available in the PubMed database. RESULTS: An intraoperative microscopy study of patients with sciatica showed that in all patients the hernia was adherent to the dura mater of nerve roots. During the SLR (Lasègue's) test, the limitation of nerve root movement occurs by periradicular adhesive tissue, and temporary ischemic changes in the nerve root induced by the root stretching cause transient conduction disturbances...

Transcaval access has been used successfully for over 200 transcatheter aortic valve replacements, large-bore percutaneous left ventricular assist devices, and thoracic endovascular aortic aneurysm repairs. This review teaches how to plan transcaval access and closure based on computed tomography. The main planning goals are to: 1) identify calcium-free crossing targets in the abdominal aorta along with optimal fluoroscopic projection angles and level with respect to lumbar vertebrae; 2) identify obstacles such as interposed bowel or pedunculated aortic atheroma; 3) plan covered stent bailout; and 4) identify jeopardized vascular branches such as renal arteries that might be obstructed by bailout covered stents if employed...

This paper deals with two recent cases of Inferior Caval Vein (IVC) duplicity, congenital anomaly often but not always asymptomatic that should be considered in the differential diagnosis of flank pain when other more common disorders have been excluded. Here are described the clinical and surgical significance together with the typical sonographic findings useful for the diagnosis of IVC duplicity. Particular attention is given to a peculiar and easily repeatable sonographic aspect associated with IVC duplicity, not previously reported in Literature and that we called the "Neptune's sign"...

Nutcracker syndrome (NCS) is symptomatic unilateral renal venous hypertension due to compression of the left renal vein between the superior mesenteric artery and aorta (anterior NCS) or between the aorta and spine (posterior NCS). The left ovarian or spermatic vein empties into the left renal vein and is an additional site of venostasis in about half the cases of NCS. The presenting symptom of NCS in about half the cases is atypical left flank pain suggesting a disorder of the lower ribs or thoracolumbar spinal junction, particularly as the pain worsens with standing and increased lumbar lordosis...

The aim of the present study was to investigate the inhibitory effects of celastrol-loaded nanomicelles (CNMs) on activated macrophage-induced corneal neovascularization (CNV) in rats and cytokine secretion in macrophages. Using an angiogenesis assay in vitro, we detected the effects of CNMs on human umbilical vein endothelial cell (HUVEC) migration and invasion. In addition, the expression levels of cytokines secreted from hypoxia-induced macrophages were assessed through cytokine array analysis. The expression of hypoxia-inducible factors-1α (HIF-1α), nuclear factor-kappa B p65 (NF-κB p65), phospho-nuclear factor-kappa B p65 (phospho-NF-κB p65), p38 mitogen-activated protein kinase (p38 MAPK), phospho-p38 MAPK, extracellular signal-regulated kinase 1/2 (ERK1/2), and phospho-ERK1/2 was analyzed by western blotting...

Obtaining intravascular access in the neonatal intensive care unit (NICU) is not only critical but also technically challenging. Malposition of the catheter tip is a known and well-documented complication. Specifically, peripherally inserted central venous catheter (PICC) line insertion into the ascending lumbar vein can lead to neurological dysfunction and, in some cases, even death. We present the first reported case of pneumorrhachis (PR) following PICC line insertion into the ascending lumbar vein. Our patient presented with lower extremity weakness and imaging confirmed the presence of air within the spinal canal...

BACKGROUND: For radiologists, the venous drainage of adrenal glands is a key to the technique of selective adrenal venous sampling. For endocrine surgeons, it is key to adrenalectomy for carcinoma and pheochromocytoma. This study aims to demonstrate direct anastomosis between the left adrenal vein, the diaphragmatic circulation and the azygos system. Anatomical textbooks only offer very little information concerning the left adrenal vein (LAV) and its potential anastomosis with the reno-lumbo-azygo trunk (RLAT) and the diaphragmatic circulation...

Background and aims: In Japan, stripping under general anesthesia, lumbar anesthesia and tumescent local anesthesia has been used in the treatment of primary varicose veins due to saphenous vein insufficiency. However endovenous laser ablation (EVLA) using a 980 nm diode laser has received National Health Insurance (NHI) coverage in 2011, while EVLA using a 1470 nm diode laser with a radial 2-ring fiber has received coverage in 2014. As a result, the use of EVLA has become widespread in Japan. We herein report on the results of varicose veins treatment at our hospital...

A 36-year-old male presented with progressive exertional dyspnea over months. Physical examination showed jugular venous distension, lung crecipitations, femoral bruit and pitting pedal edema. Echocardiogram showed a dilated right ventricle with severe pulmonary hypertension and a non collapsing inferior vena cava (IVC). On right heart catheterization, IVC oxygen saturation was noted at 92% suggesting arterial mixing; a computed tomography of the abdomen showed a fistula between the right common iliac artery to the right common iliac vein at L4 level and a massive IVC; this was linked to trauma from a disectomy done 16 years ago at L4-L5 level...

Horner syndrome is rarely observed in connection with epidural anesthesia. It is characterized by ptosis, enophthalmos, miosis, anisocoria, and conjunctival hyperemia in the affected eye, as well as anhydrosis and flushing on the affected side of the face. It is usually a complication spontaneously resolved without permanent neurological deficits. Intraoral anesthesia; stellate ganglion, cervical or brachial plexus blocks; thoracic, lumbar or caudal epidural anesthesia, and intrapleural analgesia are the main causes for Horner syndrome related to anesthesia...

This case report is about a 70-years-old female patient, suffering from discal hernia, with compression of the iliac vein, that led to the formation of deep vein thrombosis of the lower limbs. The angio-CT scan revealed the starting point of the L4- L5 compression where a voluminous discal hernia caused deep vein thrombosis, with the involvement the femoro-popliteal venous axis. Blood samples and PET-CT scans excluded other possible etiologic factors. This case demonstrates how a voluminous discal hernia can cause venous thrombosis...
