[The selective phlebography of the large tributaries of the vena cava system in the diagnosis of venous circulatory disorders in the spinal complex].

As any other organ, the spinal cord also suffers in chronic congestion. Since the epidural venous system drains into the vena cava system and participates in collateral circulation, there is increased inflow with impaired blood flow along its large tributaries in the vertebral canal along with poor outflow, resulting in intracanal hypertension and chronic congestion. Venous hemodynamic disorders are found beyond the vertebral canal and detected by selective phlebography of the large tributaries of the vena cava system. The technique was used to examine 46 patients with spastic paraparesis or tetraparesis of unclear etiology, which provides evidence for the fact that vena cava stenoses, compressions, atresia, and thromboses can be responsible for impaired venous hemodynamics in the vertebral apparatus and its surgical correction is possible.

[Phlebography of the talus following fracture and dislocation (preliminary report)].

After dislocation or dislocated fracture of the talus late arthrosis is a frequent complication, in which primary bone and cartilage damage play a role. For the demonstration and preclusion, resp., of the vascular damage phlebography performed 3--6 months after the injury is recommended by the authors--by means of which favourable initial experiences could be obtained.

A simple aid in greater saphenous phlebography.

During the last 32 months, we have used isometric contraction of the muscles of the lower extremities during saphenous phlebography for the purpose of improving the degree of opacification of the greater saphenous vein. Using this technique, acceptable visualization of the greater saphenous system may be obtained with minimal risk in over 90 per cent of the patients.

[Technique, complications, possible misinterpretations and indications of retrograde renal phlebography (author's transl)].

A chronological survey is given of the gradual development of retrograde renal phlebography whereby the different techniques are contraste with each other in detail. Today's method of choice is the retrograde selective visualization of renal veins using the Seldinger procedure via the femoral vein, with or without pharmacological influence and applying larger doses of contrast medium (up to 30 ml) and higher injection pressures (up to 6 kg/cm2). Indications for simple and for pharmacophlebography are specified and exemplified by means of a scheme. Possible complications and misinterpretations are discussed.

[Role of spermatic vein phlebography and scleroembolization in treating varicocele and preventing its recurrence].

The phlebograms and intravascular treatment of varicocele were performed in 406 patients aged from 10 to 60 years. Scleroembolization of the left internal spermatic vein was successfully used in 402 of them. Dilatation and retrograde flow through the right internal spermatic vein were recorded in 101 of 238 patients during transjugular catheterization. This investigation has confirmed high effectiveness of the method of the intravascular combined scleroembolization in treatment of varicocele. Using the transjugular access facilitates not only performing the left side intervention but represents the only efficient means to fulfill the right side phlebography of the spermatic vein and its obliteration. The strategy of using the bilateral intervention for the detection of retrograde contrast of the right internal spermatic vein considerably improves the results of treatment of varicocele and decreases risk of relapses.

[Technique and results in adrenal phlebography (author's transl)].

Following a brief description of the anatomy of the adrenal gland the technique of adrenal phlebography is explained. So far this method has been used in 118 patients. This examination is indicated in cases with suspected hormon - active disease of the adrenal glands and to rule out spaceoccupying lesions as well as metastases in the adrenal gland. Characteristic radiologic findings are demonstrated. Causes for complications of this method and their possible prevention are discussed.

[Selective epidural phlebography in the diagnosis of tumors of the cervical spinal cord and of the cauda equina roots].

The method of selective epidural phlebography (SEP) was applied in the diagnosis of tumors of the cervical segment of the spinal cord and the roots of cauda equina in 45 patients. The diagnosis was confirmed in 32 of the 37 patients who were operated on. The SEP method does not produce serious complications and allows circulatory disorders in the vertebral venous plexuses to be revealed. The diagnostic value of the method is higher in tumors of superocervical localization and hourglass tumors.

[Lumbar phlebography. Normal aspect and its value in diagnosis of herniated disk].

Our technique of lumbar phlebography involves selective catheterisation of the lateral sacral veins with or without catheterisation of the ascending lumbar veins. Injection of these veins, in association with abdominal compression, produces good filling of the intra-spinal epidural veins, particularly at L5-S1 level. The anatomy and radiological appearances of the epidural veins are discussed. The phlebographic signs of disc herniation are presented. The diagnostic potential of this technique seems very promising in disc pathology, especially in the diagnosis of L5-S1 herniation and lateral prolapse at all levels.

[The value of plain x-ray diagnosis and phlebography in the thoracic outlet syndrome].

The compression of the neurovascular bundle of the upper limb (thoracic outlet syndrome, TOS) can be caused by osseous, muscular, fibrous, tumourous and habitual abnormalities of the cervicothoracic junction. Osseous causes can be shown in a conventional x-ray of the cervicothoracic junction. In about 40% of the cases there is a venous stenosis which can be proved by means of phlebography in a special patient position (provocation position). The type of stenosis and location provides information on the cause of it. We examined 34 patients.

Arterial phlebography of the leg.

On conventional ascending phlebography of the leg the deep femoral and pelvic veins are poorly visualized or not visualized at all. These veins are presumed to be the site of thrombosis and a source of pulmonary embolism in many instances. Diagnostic images of deep femoral and pelvic veins were obtained in 4 patients using injection of 30 ml of iopromide 300 mg I/ml into the iliac artery and DSA imaging of the venous phase of the angiogram.

[Real-time sonography in deep thrombosis of the pelvic and leg veins. A prospective comparison to phlebography].

Real-time B mode ultrasound is a well accepted diagnostic procedure in the non-invasive vascular examination. In a prospective study we examined 101 patients with clinical suspected deep vein thrombosis of the pelvis or leg using ultrasound and contrast venography within 24 hours and we compared the results of both examinations. All veins of the pelvis and lower extremities were scanned in transverse and longitudinal planes. 113 venograms were obtained; they demonstrated the presence of isolated proximal vein thrombosis in seven patients, seven isolated calf vein thromboses and 43 thromboses of both proximal and calf veins. The sensitivity of ultrasonography for detecting deep vein thrombosis in the proximal veins of the lower extremity was 98%, the specificity was also 98%. In the veins of the pelvis the sensitivity was 78%, the specificity 98% and in calf veins 60% and 97% respectively. The sensitivity for the detection of isolated calf vein thrombosis was only 14%. We conclude that ultrasonography has a very good sensitivity for detecting proximal vein thrombosis of the lower extremity and thrombosis of the pelvic veins. Phlebography remains the better method in detecting isolated calf vein thrombosis because of the difficult visualisation of the small calf veins by ultrasonography.

Decrease of plasma prekallikrein and kallikrein inhibitors during intravenous phlebography.

Complex contact activation systems may have major involvement in side effects of i.v. contrast media. To investigate this, quantitative measurements of several factors (plasma prekallikrein, kallikrein inhibitory activity, haematocrit, alpha-2-macroglobulin, antithrombin III, alpha-1-antitrypsin and beta-thromboglobulin) were made before and after i.v. contrast phlebography in two groups of patients (each containing 21 patients) with no thrombosis, using a high- (meglumine iodamide) and a low-osmolality (ioxaglate) contrast medium. A statistically significant decrease in plasma prekallikrein was observed after the high-osmolality contrast medium, which is a sign of the activation of the kallikrein-kinin system and an indicator of the activation of the intrinsic coagulation. These events may play an important role in the adverse effects of contrast media.

CT, myelography, and phlebography in the detection of lumbar disk herniation: an analysis of the literature.

Despite the large number of reports on the relative usefulness of various radiographic procedures for the diagnosis of lumbar disk herniation, there has been no consensus of opinion on the best imaging procedure. Different study designs, including criteria for patient selection and retrospective consideration of patients who underwent surgery only, hamper direct comparisons between studies. A major drawback is the common use of "accuracy" as a measure of quality. We reviewed the CT, myelographic, and phlebographic findings in lumbar disk herniation published since 1970. After the reports were systematically classified and assessed for quality, the results became more coherent. Many results tend to be sensitive and not very specific. We found there was no clear difference in the overall diagnostic quality of phlebography, myelography, and CT.

[Diagnosis of femoropopliteal venous thrombosis. Comparison of dynamic ultrasonic scanning and phlebography].

Forty patients with a clinical suspicion of deep venous thrombosis (DVT) of the lower limb were submitted to real-time ultrasound examination prior to venography. The ultrasound diagnosis DVT was made at the presence of at least one of two criteria: intraluminal thrombus and absence of vein compressibility. One ultrasound study was inconclusive. In 14 patients the ultrasound diagnosis was DVT, and in 12 of these this was confirmed at phlebography. There were thus two false positive ultrasonic diagnoses, PV pos = 0.86. In 25 patients, the diagnosis was no DVT on both ultrasound study and venography, PV neg = 1.00. Ultrasound examination is recommended as the first choice of diagnostic imaging in patients with suspected DVT.

[Ultrasonic scanning, is it an alternative to phlebography in deep thrombophlebitis of the leg?].

A material of 27 patients with clinically suspected deep thrombophlebitis in the lower limbs were examined both by ultrasonic scanning and by phlebography. We found a true negative diagnostic frequency of 100% and true positive diagnostic frequency of 85% by ultrasonic scanning. On the basis of this finding, ultrasonic scanning is proposed as the primary investigation in cases of suspected deep thrombophlebitis in the lower limbs.

Ascending lower limb phlebography: comparison of ioversol and iothalamate meglumine.

Fifty patients undergoing ascending phlebography of a lower limb were evaluated, in a randomized double-blind fashion, to compare the efficacy, patient tolerance, and safety of two different contrast agents. Ioversol-240 (MP-238), a new nonionic agent, and iothalamate-202 (Conray 43), an established ionic agent, were the contrast agents used. Twenty-five patients were injected with iothalamate and 25 with ioversol. The phlebograms were evaluated for diagnostic quality and the patients for symptoms, with special reference to complaints of heat and pain. No significant difference was demonstrated between the two agents in either examination quality or patient tolerance. No major contrast-related reactions were recorded. We conclude that ioversol-240 appears to be a safe and acceptable alternative to iothalamate-202.

Comparison of real-time B-mode ultrasonography and bilateral ascending phlebography for detection of postoperative deep vein thrombosis following elective hip surgery. The Venous Thrombosis Group.

A prospective study compared real-time B-mode ultrasound examination with bilateral ascending phlebography in the diagnosis of postoperative deep vein thrombosis in 60 patients undergoing elective total hip replacement. The overall sensitivity and specificity of the ultrasound method were 54 and 91%, respectively, and the positive and negative predictive values were 83 and 69%, respectively. The rather low overall sensitivity of the ultrasound method in this study was due to difficulty in detecting thrombi smaller than 1 cm wherever they were located in the deep veins, and in diagnosing thrombi in the calf, regardless of their size. We conclude that real-time B-mode ultrasonography is a technique that can easily be used routinely for detection of postoperative DVT in hip surgery, but its sensitivity for proximal thrombosis (63%) is too low for it to be used alone.

[Phlebography of the lower limbs: comparative trial of iopromide 370 and ioxaglate 320 mgI/ml].

Twenty patients received an injection of either iopromide 370 (10 patients) a new nonionic contrast medium, or ioxaglate 320 (10 patients) the ionic low osmolar contrast medium, in a randomized prospective trial, for phlebography of the lower limbs. A concentration of 320 mgI/ml is prescribed (more often) than 370 mgI/ml for this examination in France, where a concentration of about 300 mgI/ml is recommended. We decided to compare iopromide 370 because in some clinical situations (varicose veins, very tall patients...) this concentration may be necessary. This study demonstrates the good safety of iopromide 370, comparable to ioxaglate 320 mgI/ml, in spite of its higher concentration.
