Patients with hepatocellular carcinoma who are on liver transplant waiting list usually require local treatment to limit any risk of tumour growth. Historically percutaneous radiofrequency ablation or transarterial chemoembolization represented the major therapeutic alternatives. Depending on the size, or the topography of the lesion these two techniques may not be feasible. Read More

Rarely encountered in the Western countries, membranous occlusion of the inferior vena cava results from a fibrous thickening of the intima and is commonly located at the orifices of the hepatic veins. To date, two etiopathogenic hypotheses have been formulated: the first, dealing with the embryological aspect, the second, arguing for a thrombotic origin. Nevertheless, several studies are still underway to understand the exact physiopathological mechanism of this obstruction. Read More

Introduction: We report the evolution of the largest, contemporary, single-institution experience with this complex procedure to highlight the value of a cross-discipline, team-based approach.

Methods: Patients from a prospectively maintained database who underwent resection of renal cell carcinoma (RCC) with inferior vena cava (IVC) tumor thrombus from 2005 to 2016 at a single-institution were included for analysis.

Results: Of 140 patients, 102 (73%) had tumor thrombus below the level of the hepatic vein confluence, and 96 (69%) were performed for curative-intent, while 43 (31%) were cytoreductive procedures for clinical trial consideration. Read More

Risks of IVC filter insertion are numerous but include IVC stenosis or thrombosis and may result in caval occlusion. Acute IVC occlusion is almost always symptomatic, and treatment can be aggressive such as catheter-directed thrombolysis or conservative such as anticoagulation. The more challenging cohort of patients is those where there has been chronic complete occlusion of the IVC without symptoms, sometimes only identified at the time of routine filter retrieval.

Inferior vena cava (IVC) aneurysms are a rare finding, whose management and outcomes remain uncertain due to their low incidence and long-term follow-up. As IVC aneurysms remain a poorly understood clinical entity, it is important to expand upon our existing knowledge base as new cases arise.

Department of Surgery, Seoul National University College of Medicine, Seoul, Korea.

Background: Status in terms of major vascular structure invasion is a crucial factor for successful major hepatic resection. In particular, surgery for advanced tumors with inferior vena cava (IVC) invasion is difficult and may even be dangerous for the patient, having high risk of massive bleeding and greater chance of embolic complications such as stroke, bowel ischemia, and pulmonary venous thrombosis. For such reasons, many surgeons hesitate to carry out such surgical resection, and even if they do so, may not totally remove the tumor including the part inside the IVC, achieving R1 resection.

Rationale: Inferior vena cava (IVC) thrombosis is an under-recognized entity that is associated with a mortality rate approaching twice that of lower extremity deep venous thrombosis (DVT). Thrombolytic therapy not only results in greater lysis, but also results in higher complication rates than anticoagulation alone. Catheter-directed thrombolysis (CDT), which is effective in accomplishing local resolution whilst reducing bleeding complications, has been established as an alternative treatment for patients with extensive DVT.

Pulmonary embolism (PE) results from deep vein thrombosis (DVT) and can lead to chronic thromboembolic pulmonary hypertension (CTEPH) involving vascular dysfunction. Mechanisms are incompletely understood, in part due to lack of mouse models. We induced PE in C57BL/6 mice by intravenous injection of thrombin (166 U/kg BW), confirmed by a sudden bradycardia, bradypnea, and an increase in pulmonary artery (PA) pressure observed by high-frequency ultrasound.

Background: Complete encasement of the inferior vena cava by retroperitoneal tumors is rare. Although replacement of the vena cava has been considered for various conditions in adults, it is rarely used in children except for challenging resections and as a last chance approach - often aiming more at debulking than cure.

Materials And Methods: From January 2009 to February 2017, 4 patients (2 adrenal neuroblastomas, 1 renal cell carcinoma, 1 infantile fibrosarcoma) underwent elective en-bloc resection of tumor and of the infrahepatic portion of the inferior vena cava (IVC), with planned IVC prosthetic replacement.

BACKGROUND Epidural venous plexus (EVP) engorgement occurs due to many conditions, so it can be easily misdiagnosed. This becomes problematic when the diagnosis requires prompt treatment for a good outcome, especially when it results in cauda equina syndrome (CES). We report a case of extensive iliocaval thrombosis leading to epidural venous plexus and ascending lumbar vein engorgement as an outcome of deep venous thrombosis (DVT) due to probable adverse effects of oral combined contraceptive pills (OCCP).

Iliocaval thrombosis, or thrombosis of the inferior vena cava and iliac veins, is associated with significant morbidity in the form of limb-threatening compromise from phlegmasia cerulean dolens, development of post-thrombotic syndrome, and death secondary to pulmonary embolism. Endovascular iliocaval reconstruction is an effective treatment for iliocaval thrombosis with high levels of technical success, favorable clinical outcomes and stent patency rates, and few complications. It is often able to relieve the debilitating symptoms experienced by affected patients and is a viable option for patients who fail conservative management. Read More

Thromboses of the superior and inferior vena cava, either isolated or associated with distal deep venous thrombosis, are uncommon, but confer potentially serious morbidity and mortality. Incidence is increasing, especially with the prominence of intravascular devices. The range of treatment options is also expanding to include medical management, surgery, and endovascular techniques which are now frequently considered first line therapy due to lower reintervention rates and decreased periprocedural morbidity.

When the Budd-Chiari syndrome (BCS) lesion extends to the inferior vena cava (IVC) or the orifices of the hepatic vein, the thickened IVC and/or hepatic vein wall must be removed and IVC reconstruction is required in living-donor liver transplantation (LDLT). In various reports about IVC resection in LDLT for BCS, there are none about left lobe liver transplantation with reconstruction of the retrohepatic IVC (rhIVC). To overcome removal and reconstruction of the rhIVC in LDLT for BCS, we introduced a composite IVC graft that is applicable to both right and left lobe partial liver grafts for LDLT for BCS.
