“…So in the end, pulmonary embolism (PE) remained as the most likely possibility despite the conflicting diagnostic testing results. Although helical (spiral) CT with bilateral upper extremity contrast injection has a reported sensitivity of 98 percent for diagnosing PE [9]; in some studies the sensitivities have ranged from 53 to 87 percent, even for segmental or larger emboli [10-12]. Obviously, the specificity of helical CT scanning depends on reader experience and results must be interpreted with caution, particularly if the clinical probability of pulmonary emboli and the CT results are discordant.…”

Background: An unusual sequence of post operative events heralded by hemodynamic deterioration followed by dyspnea and rapidly progressive dilatation of superficial neck and facial veins, resembling a superior vena cava syndrome, two days post surgical resection of filamentous aortic valve masses, closure of a patent foramen ovale, and performance of a modified Maze procedure for atrial fibrillation in a patient that presented with transient neurologic findings is presented.

“…Venography, however, provided excellent characterisation of the venous anatomy and the site and extent of venous obstruction, necessary for decision-making for the therapeutic strategy. Notwithstanding the limitations of computed tomography in delineating venous anatomy, it is an essential examination to exclude external compression as a cause of SVC syndrome and to characterise the nature of the extrinsic compression [6,16,17].…”

“…In the case of stenosis of the CTV system (Stanford types I and II), care should be taken to avoid the risk of venous obstruction and subsequent SVC syndrome after HC placement. For this reason and in the presence of blood clots, angioplasty and stent are justified [11]. Stent deployment is an established option for benign CTV stenosis [17][18][19][20].…”

“…All patients were asymptomatic before the procedure regarding CTV obstruction (the Kishi score for clinical signs of superior vena cava [SVC] obstruction was \4 for all patients). Helical CT phlebography using the technique described by Qanadli et al [11] (n = 2) or digital phlebography (n = 11) was done prior to the procedure to evaluate the CTV circulation including stenosis and occlusion evaluation and collateral supply assessment. In one patient, helical CT phlebography failed and a digital phlebography had to be performed.…”

A method for hemodialysis catheter placement in patients with central thoracic venous stenosis or occlusion is described and initial results are analyzed. Twelve patients, with a mean age of 63.2 years (42-80 years), with central venous stenosis or occlusion, and who required a hemodialysis catheter were reviewed. All lesions were confirmed by helical CT or phlebography. Five patients had stenosis while seven patients were diagnosed with an occlusion of thoracic central veins. All patients were asymptomatic, without sign of superior vena cava syndrome. After percutaneous transstenotic catheterization or guidewire-based recannalization in occlusions, a balloon dilatation was performed and a stent was placed, when necessary, prior to catheter placement. Technical success was 92%. Three patients had angioplasty alone and nine patients had angioplasty with stent placement. Dialysis catheters were successfully inserted through all recannalized accesses. No immediate complication occurred, nor did any patient develop superior vena cava syndrome after the procedure. The mean follow-up was 21.8 months (range, 8-48 months). Three patients developed a catheter dysfunction with fibrin sheath formation (at 7, 11, and 12 months after catheter placement, respectively). Two were successfully managed by percutaneous endovascular approach and one catheter was removed. In conclusion, for patients with central venous stenosis or occlusion and those who need a hemodialysis catheter, catheter insertion can be reliably achieved immediately after endovascular recannalization with acceptable technical and long-term success rates. This technique should be considered as an alternative procedure for placing a new hemodialysis catheter through a patent vein.
