Each main kind of cancer has rather typical or atypical clinical presentations, depending upon several factors related to histopathology or staging. The diagnosis of renal cell carcinoma associated with an extensive inferior vena cava tumor thrombus usually implies prognostic, workup, and surgical management issues. The incidental discovery of this rare clinical entity presented as deep vein thrombosis is narrated, with some therapeutic elements, including an example of alternative surgical treatment. The importance of preoperative assessment - particularly local regarding operability, is emphasized as well...

A sphincter on the inferior vena cava can protect the heart of a diving mammal from overload when elevated abdominal pressures increase venous return, yet sphincters are reported incompetent or absent in some cetacean species. We previously hypothesized that abdominal pressures are elevated and pulsatile in fluking cetaceans, and that collagen is deposited on the diaphragm according to pressure levels to resist deformation. Here we tested the hypothesis that cetaceans generating high abdominal pressures need a more robust sphincter than those generating low pressures...

The aim of this study was to investigate the clinical benefit of presurgical therapy with pazopanib in renal cell carcinoma (RCC) patients with a tumor thrombus extending to a high level in the vena cava. A retrospective review was performed for seven consecutive patients with RCC and tumor thrombus involving the vena cava above the hepatic vein (level 3-4, Mayo Clinic classification) treated with pazopanib without initial cytoreductive nephrectomy at our institution. The effect of pazopanib was assessed in terms of the primary site response, thrombus diameter, and height (before and after treatment) on computed tomography or MRI...

Venous compression syndromes are caused by extrinsic venous compression of anatomical structures, such as the adjacent arteries and bones. Chronic venous compression and pulsative vibratory arterial pressure accelerate the development of deep vein thrombosis. Herein, we report the first case of double venous compressions due to a duplicated inferior vena cava-induced right-sided common iliac vein thrombosis. The thrombus was induced by left-sided inferior vena cava entrapment and right-sided common iliac vein compression, resembling nutcracker syndrome and May-Thurner syndrome, respectively...

Uterus transplantation may become the surgical therapeutic modality of choice for uterine factor infertility. However, this procedure still faces technical, therapeutic, and immunologic challenges that limit its success and clinical application. Experimental studies are therefore still needed to address various challenges in the field of uterus transplantation. Among various laboratory animals, small animals are ideal models for the purpose of experimental uterus transplant. However, clinical success in small animal models is not generalizable to clinical application and treatment for uterine factor infertility in humans...

Ovarian vein thrombosis (OVT) is an rare condition, which can present in the postpartum period. We present a case of a 35-year-old female who presented with right lower quadrant pain and fever. Her computed tomography (CT) abdomen revealed a dilated right ovarian vein with soft tissue attenuation material in its lumen that extended into the inferior vena cava, along with fat stranding of the surrounding soft tissues signifying thrombophlebitis. She was treated with enoxaparin and piperacillin-tazobactam, which lead to a resolution of the thrombus...

Central venous thromboses are common and pose challenges in the care of chronically ill pediatric patients. Among patients with intestinal failure (most commonly because of short bowel syndrome) who depend on parenteral nutrition, progressive loss of central venous access sites is a potentially fatal complication. We present the case of a 5-year-old girl with parenteral nutrition-dependent short bowel syndrome and no remaining standard central venous access sites despite medical anticoagulation, in whom angioplasty and stent implantations were used to reconstruct chronically occluded central veins...

INTRODUCTION: Spontaneous migration of synthetic grafts had been described after abdominal vascular procedures into the duodenum and small bowel. In the setting of liver transplantation, synthetic grafts are commonly used for overcoming shortened or poor-quality vasculatures. We describe a case of spontaneous migration of thrombosed synthetic vascular graft after living-donor liver transplantation (LDLT). PRESENTATION: A 59 years male patient with end stage liver disease underwent LDLT utilizing a right hemi-liver graft...

A 32-year-old man with a history of bronchial asthma was referred for low back pain and bilateral femur pain. Vascular sonography revealed bilateral deep vein thrombosis (DVT) from the femoral veins to the popliteal veins. Computed tomography revealed hypoplasia of the inferior vena cava (IVC) and dilated lumbar veins, ascending lumbar veins, and azygos vein as collaterals. There was no evidence of malignant neoplasm. The results of the thrombophilia tests were within normal limits. Hypoplasia of the IVC is a rare cause of DVT...

Nutcracker syndrome is a condition where there is compression of the left renal vein between the aorta and the superior mesenteric artery causing symptoms. Here, we describe the case of a female patient who had symptoms secondary to the compression of a left inferior vena cava between the aorta and the superior mesenteric artery causing a nutcracker syndrome. We will review the etiology, embryology, and imaging of the inferior vena cava and nutcracker syndrome.

Retroperitoneal pleomorphic liposarcoma (RPLS) is the least common but the most aggressive subtype of liposarcoma. We herein report a case of tumor embolism (TE) to the inferior vena cava (IVC) and pulmonary arteries in a 54 years old woman with RPLS. The case suggests that fusion fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG PET/CT) can accurately detect occult TE. It also illustrates the usefulness of computed tomography (CT) and high18 F-FDG uptake by PET/CT imaging for diagnosing such findings as filling defect in the veins and beaded pulmonary arteries as TE...

BACKGROUND: Occlusion of the inferior vena cava (IVC) often causes venous claudication, leg swelling, or skin changes. We hypothesized that the outcome of nitinol stents for endovascular reconstruction of the IVC is similar to the outcome reported for steel alloy stents. METHODS: From the prospective Bern Venous Stent Registry, we investigated technical success, patency rates, and clinical outcome in consecutive patients with endovascular IVC reconstruction. During routine follow-up visits, stent patency was assessed by duplex ultrasound...

Budd-Chiari syndrome (BCS) is a clinical condition resulting from impaired hepatic venous drainage, in which there is obstruction to the hepatic venous outflow at any level from the small hepatic veins to the junction of the inferior vena cava and the right atrium leading to hepatic congestion. The diagnosis of BCS is based on imaging, which can be gathered from non-invasive investigations such as ultrasonography coupled with venous Doppler, triphasic computed tomography (CT) and magnetic resonance imaging (MRI)...
