Arterioportal shunts may be congenital (vascular malformations in Rendu-Osler disease) or acquired (trauma, iatrogenic causes, cirrhosis) and consist of a communication between the hepatic artery and the portal venous system.

The cavernous sinuses are hollow spaces located under the brain, behind each eye socket. In preliminary studies, stent placement in chronically occluded iliac veins contributed to ulcers healing, PTS symptoms relief, and reduced obstructive venous sequel.93, No randomized controlled trials are available, the largest series found patients with moderate-to-severe PTS to have reduced pain (P < 0.0001), severe pain (from 41% to 11%), and severe swelling (from 36% to 18%); increased ulcer healing (68%), and reduced venous pressure following recanalization with stent placement.93 Claudication improvement, better outflow fraction, and calf pump function was also observed.94.

Most such patients present with symptoms of elevated intracranial pressure that may rapidly escalate to a coma ( , 45 , , 46 ). Herein, we discuss the case of a 40-year-old gentleman who presented with cerebral venous sinus thrombosis (CVST) as the first manifestation of underlying SLE. Most portal venous system aneurysms are asymptomatic and do not demonstrate a significant increase in size once discovered, although some manifest with nonspecific abdominal pain as a major symptom. (a) Longitudinal color Doppler US image shows an abnormal communication between the left portal vein (VPI) and the middle hepatic veins (VHM). Venous US is recommended as first line imaging method for DVT diagnosis. Moreover, presence of concomitant DVT has been suggested as an independent 30-days death risk factor following PE.38. In this clinical setting, the arterioportal shunt may not be distinguished from a small hepatocarcinoma, and exclusion of a tumor-related arterioportal shunt requires serial examinations (,28). 103, 104 For the diagnosis and treatment refer to the Supplementary material online, only section.

Three clinical prediction rules have been derived and prospectively validated to detect low-recurrence risk patients (Table4).71 A number of bleeding scores were evaluated, none showed sufficient predictive accuracy or had sufficient validation to be recommended in routine clinical practice.72,73, Continuing indefinite anticoagulation with the same drug administered during the first months is the best option for patients with multiple VTE episodes or strong VTE familial history, those with major thrombophilia, or longstanding medical diseases at high thrombotic risk.70 Indefinite anticoagulation can also be considered in patients with first episode of unprovoked VTE, especially in those with severe presentation, provided they are at low bleeding risk.70 Finally, discontinuing anticoagulation in non-cancer patients with repeatedly negative d-dimer (before drug interruption, 15, 30, 60, and 90 days following interruption) has proved to be safe in patients with unprovoked proximal DVT provided veins are recanalized or remained stable for 1 year.74 However, using moderately sensitive d-dimer assay during and 30 days after stopping anticoagulation, these results were not confirmed in men, and in women with VTE not associated with oestrogen treatment.75 Similarly, when measurements were repeated using a quantitative assay, d-dimer testing failed to identify subgroups with very low recurrence rate.76, Risk of recurrence after a first episode of unprovoked VTE, d-dimer level at 3 weeks and 3, 9, 15, 24 months after stopping anticoagulation, VTE location (Distal DVT, Proximal DVT, PE), Abnormal d-dimer 3–5 weeks after stopping anticoagulation, VTE not associated with oestrogen-progestatif therapy in women, Abnormal d-dimer before stopping anticoagulation, Post thrombotic symptoms (hyperpigmentation, edema and redness), Four randomized studies evaluated VKA [target international normalized ratio (INR) 2.0–3.0] for VTE extended treatment in patients completing 3-months anticoagulation.77–80 Recurrent VTE occurred less in the VKA groups (combined OR 0.07).81 Bleeding was significantly higher.81.

Portal vein trifurcation. This pattern of perfusion is frequently seen and occurs because the central regions of the liver are better supplied by the cavernous portal vein than are the peripheral regions; therefore, a peripheral increase in arterial inflow develops (,23,,24).
