REVIEW
Aimee Humphries, Peter Stone, S Ali Mirjalili
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...

BACKGROUND: and Importance Although multifocal spinal arteriovenous malformations (SAVMs) have been reported before, the present case is the first case of two different types, including perimedullary arteriovenous fistula (PMAVF) and spinal dural arteriovenous fistulas (SDAVFs) of lumbosacral arteriovenous malformations (AVMs), coexisting in one patient. We also report the use of hybrid techniques in the treatment of concomitant lumbosacral SAVMs for the first time. CLINICAL PRESENTATION: A 65-year-old man presented with a 4-year history of progressive sensory, motor, and sphincter dysfunction...

STUDY DESIGN: A prospective randomized double blind placebo controlled trail OBJECTIVE.: To evaluate and compare the efficacy and safety of Batroxobin (botropase),Tranexamic acid(TXA) and their combination in reduction of perioperative blood loss in lumbar spine single level fusion surgeries. SUMMARY OF BACKGROUND DATA: Spinal surgeries are associated with significant blood loss leading to perioperative anaemia and increased need for allogenic transfusion. TXA competitively inhibits plasmin and batroxobin converts fibrinogen to fibrin and theoretically their combination is synergistic ...

In selected cases, cuffed tunneled catheters via the iliac vein are implanted as a last resort access for hemodialysis. To monitor the correct position, sonography of the inferior vena cava (IVC) is sufficient in most cases. Position control using an X-ray of the abdomen is not routinely recommended when femoral catheters are implanted. In this report, we describe the case of a 59-year-old patient on chronic hemodialysis due to granulomatosis with polyangiitis and complex shunt history with multiple shunt occlusions and revisions...

Combined primary hepatic neuroendocrine carcinoma (PHNEC) and hepatocellular carcinoma (HCC) is a very rare malignant hepatic tumor. Its prognosis and histological features are uncertain. Here we report the case of such a tumor in a 70-year-old male Japanese patient with adverse prognosis. The patient underwent a right hepatic lobectomy for a tumor mass that measured 11×10cm in diameter located in the right lobe of the liver, treated with transcatheter arterial chemoembolization (TACE) and percutaneous transhepatic portal vein embolization (PTPE) therapy five weeks before the operation...

PURPOSE: Oblique lateral interbody fusion (OLIF) L5-S1 is essentially to perform an anterior lumbar interbody fusion (ALIF) in the lateral position. Because the surgical procedures are performed "obliquely" over the left common iliac vein (LCIV), ensuring that the vein is protected which is particularly important. We aimed to evaluate the configuration of LCIV and its risk of mobilization during anterior approach at L5-S1 segment. METHODS: This study involved 65 consecutive patients who underwent anterior lumbar fusion (ALIF, n = 39; OLIF, n = 26) at the L5-S1 segment...

Splenoportal axis thrombosis not associated with cirrhosis or neoplasms has a prevalence lower than 5 per 10,000 people. An etiologic factor responsible for portal thrombosis is finally identified in most cases, usually systemic thrombogenic factors or predisposing local factors. However, despite a detailed study of all etiologic factors, up to 30% of cases are eventually considered as idiopathic in origin. We report the case of a 41-year-old patient who presented with abdominal pain and lower extremity edema...

INTRODUCTION: Long-term space flight induces a near visual acuity change in approximately 50% of astronauts. In some crew members, postflight cerebrospinal fluid (CSF) opening pressures by lumbar puncture are as high as 20.9 mmHg who demonstrated optic disc edema. CSF communicates through the cochlear aqueduct to affect perilymphatic pressure and tympanic membrane motion. We hypothesized that 50 mmHg of lower-body negative pressure (LBNP) during 15° head-down tilt (HDT) would mitigate elevations in internal jugular vein cross-sectional area (IJV CSA) and intracranial pressure (ICP)...

BACKGROUND: Production of kappa free light chains (KFLC) represents a part of humoral immune response, along with the synthesis of intrathecal immunoglobulins. Increased concentrations of immunoglobulin G light chains, kappa and lambda chains, were identified through research of numerous diseases of central nervous system. The qualitative method of isoelectric focusing (IEF) followed by immunofixation currently represents the accepted standard in identifying oligoclonal bands (OCB), but establishing a sensitive immunonephelometric method for quantification of kappa free light chains (KFLC) in cerebrospinal fluid (CSF) has paved a way for new diagnostic possibilities...

May-Thurner syndrome (MTS) also known as Cockett's syndrome is a rare condition responsible for 2%-3% of all cases of deep venous thrombosis (DVT). The thrombosis results from mechanical compression of the left common iliac vein against the body of the fifth lumbar vertebra by the right common iliac artery. Repetitive hyperplasia of the venous wall by compression results in spur formation that in turn causes venous flow obstruction and results in the DVT. Our case is a young female who had acute extensive proximal DVT due to MTS that was successfully managed using mechanical thrombectomy with a venous stent...

The testicular arteries (TAs) also known as Internal spermatic arteries are long and slender arteries usually arising from the anterolateral aspect of the abdominal aorta (AA), 2.5 cm to 5 cm caudal to the renal arteries (RA). The variation in testicular arteries may be found with respect to their origin, number or course. They can originate from the abdominal aorta itself at an abnormal level. If not arising from abdominal aorta the TA variants may arise from renal artery, supra renal artery or any one of the lumbar arteries...

OBJECTIVE: To demonstrate the clinical applicability of 3-dimensional CT angiography (3D-CTA) in evaluating the anatomic variations of inferior mesenteric artery (IMA) and left colic artery (LCA), to help make pre-operative strategies of rectal cancer surgery. METHODS: 188 patients with abdominal and pelvic contrast-enhanced CT scan were retrospectively enrolled and 3D-CTA was reconstructed. The origin and branching patterns of IMA, tracking patterns of LCA, intersectional patterns among IMA, LCA and inferior mesenteric vein (IMV) were examined, and their associations with clinical features were analyzed...

May-Thurner syndrome (MTS) results from a frequent anatomic variant in which compression of the left common iliac vein between the body of the fifth lumbar vertebra and the pulsating right common iliac artery can cause deep venous thrombosis (DVT) of the left lower limb. While anticoagulation remains the mainstay treatment of acute DVT, catheter-directed thrombolysis combined with stenting provides a safe and effective method for relieving acute symptoms and preventing postthrombotic syndrome in patients with MTS...

Crossed renal ectopia is a rare congenital anomaly, where one of the kidneys crosses the midline and lies opposite to the site of its normal ureteral insertion. Ninety percent of crossed ectopic kidneys are fused to their ipsilateral uncrossed kidney. Crossed renal ectopia without fusion is rare. We present the case of a 53-year-old male with an unusual incidental finding of crossed nonfused renal ectopia, with the left ectopic kidney lying anterior to the right kidney without fusion. The ectopic kidney had dual arterial supply: one from the aorta and another from the right renal artery...

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...
