Intercostal artery aneurysms complicating thoracic aortic coarctation: diagnosis with magnetic resonance angiography.

The case report of a 46-year-old woman diagnosed with complete aortic coarctation and multiple intercostal artery aneurysms using 'ultrafast time-resolved' multiphase contrast-enhanced magnetic resonance angiography and conventional single-phase, high-resolution breath-hold contrast-enhanced magnetic resonance angiogram techniques is presented. A review of intercoastal artery aneurysms occurring in conjunction with aortic coarctation and the various contrast-enhanced magnetic resonance angiography techniques currently available is provided.

Magnetic resonance imaging of the pancreas at 3.0 tesla: qualitative and quantitative comparison with 1.5 tesla.

Objectives: We sought to perform a preliminary comparison of signal-to-noise ratio (SNR) and image quality for magnetic resonance imaging (MRI) of the pancreas at 1.5 and 3 T.

Materials And Methods: Two imaging cohorts were studied using a T2-weighted, single-shot fast spin-echo pulse sequence and a T1-weighted, fat-suppressed 3D gradient-echo pulse sequence.

Extracerebral cavernous hemangioma of the cavernous sinus: diagnosis with MR imaging and labeled red cell blood pool scintigraphy.

We present the case of a 64-year-old man with a presumed diagnosis of extracerebral cavernous hemangioma involving the cavernous sinus. The diagnosis was made on the basis of labeled red cell blood pool scintigraphy findings in conjunction with those of MR imaging. This lesion was not altered in appearance at 6-year follow-up MR imaging.

Clostridium septicum septicaemia with myonecrosis.

A case of fatal spontaneous gas gangrene due to Clostridium septicum septicaemia associated with an occult rectal malignancy is presented. This condition has a rapid progression and a high mortality even with prompt treatment. It is important that the radiologist considers this diagnosis in an appropriate clinical setting to allow rapid instigation of appropriate therapy.

Deep vein thrombosis of the legs: new therapy by means of low molecular weight heparins.

This open controlled study compared the effects of subcutaneous administration of two types of heparin in two groups of 40 patients each with deep vein thrombosis. One group received calcium heparin and the other received low molecular weight heparin for 40 days in each case. Patients receiving low molecular weight heparin showed a greater increase in inhibition of activated factor X than those receiving calcium heparin.

A multicentre study on LMW-heparin effectiveness in preventing postsurgical thrombosis.

A multicentric study was carried out involving six italian departments of general surgery to assess the efficacy of a low molecular weight (LMW) heparin called Fluxum compared to standard calcium heparin in low doses for prevention of postoperative thromboembolic complications (deep vein thrombosis and pulmonary embolism). 610 patients were treated; 308 (50.5%) of whom were treated with Fluxum at doses of 4,000 or 8,000 I.

Prevention of postoperative deep vein thrombosis by two different heparin types.

The effectiveness of two different heparin types in preventing deep vein thrombosis after surgery was studied in 173 patients, randomly assigned to treatment by a new low molecular weight (LMWH) heparin or trade calcium heparin (CH). Both drugs were administered subcutaneously, 2 h before surgery and for 7 days after, at dose of 7,500 anti activated factor X Units once a day in low molecular weight heparin group, or 5,000 International Units t.i.

Time-course of anti-Xa effects of calcium heparin and low-molecular-weight heparin given s.c.: insights for thrombosis prevention.

Thirty healthy volunteers underwent a pharmacokinetic study to control the effect of calcium heparin and low-molecular-weight heparin on coagulation factors. Activated partial thromboplastin time (aPTT), thrombin time (TT) and inhibition of activated factor X (Xa) were checked after a single subcutaneous administration of calcium heparin, 5000 IU (CH group); low-molecular-weight heparin 7500 AXaU (LMWH-LD group); and LMW heparin, 15,000 AXaU (LMWH-MD group). The mean values of aPTT rose significantly only after administration of LMW heparin (15,000 AXaU), while no relevant variations were observed after CH and LMWH-LD administration.
