Transbrachial angiography: an effective and safe approach.

BACKGROUND: Description of the technique of the transbrachial catheter diagnostics, retrospective evaluation of the technical success rate and the complications. PATIENTS AND METHODS: In a period of 8 years the transbrachial approach was used in 2555 patients, 1734 men and 821 women with an average age of 62.9 years. The investigation was done with outpatients in approximately 90% of the cases. Usually, the preferred arm was not punctured. For the diagnostics F4 and F5-catheter sheaths and selective catheter and/or plain catheters were used. RESULTS: 12 times (0.47%) the investigation did not succeed technically. The image quality of the vascular representations was diagnostically sufficient. The total complication rate amounted to 0.47%. The following complications appeared: four dissections in the site of puncture, one embolism into arteries at the forearm, three transitory ischemic attacks, four haematoma at the site of puncture. CONCLUSIONS: The transbrachial catheter diagnostics is a little invasive, efficient and low-risk method, which is practicable in out-patients.

The brachial artery as approach for catheter interventions--indications, results, complications.

BACKGROUND: Evaluation of the technical practicability of the acute results and complications with transbrachial catheter interventions. PATIENTS AND METHODS: Retrospective investigation of 156 catheter interventions with 147 patients within the period of 4/2000 to 12/2003. Target vessel, technical success, complications and in- or out-patient' practicability received special consideration. RESULTS: The intervention was technically successful in 94%, 10 times segment obliterations of the distal femoral artery could not be recanalised. Renal arteries and mesenteric arteries going off steeply, processes of the femoral bifurcation, bypass stenosis, bilateral distal vascular processes as well as difficult puncturable or not puncturable inguinal arteries are particularly suitable for transbrachial procedure. Three complications arose, two haematoma, conservatively treated, and one cerebrovascular insult. CONCLUSIONS: Many vascular processes can be treated without any problem by transbrachial approach. The technical success rates are very high. The interventions can be realized without hospitalisation of the patient, except for some special cases (renal arteries and mesenteric arteries). The complication rate is low, condition is a large experience of the examiner.

[Grading of carotid artery stenosis using high resolution dynamic magnetic resonance angiography in comparison to intraarterial digital subtraction angiography. Are stenoses over 70% reliably detectable?].

PURPOSES: Evaluation of high resolution dynamic magnetic resonance angiography (ceMRA) in detection and graduation of carotid artery stenosis in comparison to intraarterial digital subtraction angiography. MATERIALS AND METHODS: Magnetic resonance angiography and intraarterial digital subtraction angiography was performed in 65 patients with suspected carotid artery stenosis by ultrasound examination. Detection and graduation of carotid artery stenosis by magnetic resonance angiography were compared to those of intraarterial digital subtraction angiography after stenosis grading according to NASCET criteria. RESULTS: All magnetic resonance angiographies were of excellent quality, with 46 stenoses type I and II and 12 stenoses type III NASCET correctly identified and classified by magnetic resonance angiography. Overestimation was found in 4 cases and underestimation in 2 cases. Both modalities detected 13 occlusions. Sensitivity and specificity of ceMRA were 92%. The positive predictive value was 86% and the negative predictive value 96%. CONCLUSION: High resolution dynamic magnetic resonance angiography is suitable in detecting and classifying carotid artery stenoses over 70% with high sensitivity and specificity in comparison to intraarterial digital subtraction angiography. Intraarterial digital subtraction angiography should only be performed in critical cases.

[Stent PTA in secondary symptomatic proximal subclavian artery obstruction].

Stent-PTA of secondary symptomatic proximal subclavian artery stenosis In comparison with conventional surgical revascularisation, percutaneous transluminal angioplasty (PTA) is an alternative treatment for short stenoses or occlusions involving the origin of the subclavian artery. If there is clinical suspicion of subclavian artery obstruction (e.g. blood pressure difference in both arms), digital subtraction angiography of the aortic arch and upper limb should be performed prior to creating radial haemodialysis shunts or coronary bypass crafting involving the internal mammary artery. PTA and stenting can be successfully carried out in symptomatic secondary proximal subclavian artery stenosis, e.g. in radial haemodialysis fistulas with distal ischaemia.

[Veno-occlusive dysfunction as a cause of erectile impotence: therapy of venous leak with retrograde embolization of the internal pudendal vein].

"Venous leak impotence" remains a therapeutic challenge as long term success rates with all interventions are only 50%. Surgical venous ligation is a well established procedure, yet not all pathological venous groups can always be occluded. Retrograde embolisation of angiographically identified pathological venous groups represent a promising alternative to surgical isolation and antegrad embolisation of deep dorsal penile veins. Four young men (19-42 years) presented with complete loss of erection. Vaginal intercourse was impossible. Pharmaco-duplex sonography with Prostaglandin E, 10-20 micrograms demonstrated normal arterial flow in all 4 penile arteries but even after intra-cavernosoal injection of Prostaglandin E, 20 micrograms no complete erection was achieved. Dynamic infusion cavernosometry showed increased maintenance flow. Cavernosography showed a venous leak involving the deep dorsal penile vein in all four cases. Embolisation was carried out via the femoral vein by coaxial technique using Histoacryl-Lipiodol solution in order to embolise all angiographically identified insufficient veins. At one year follow up all 4 patients still achieved spontaneous erections without any additional medical treatment.

[CT Venography and CT Angiography of the Pulmonary Arteries in Acute Pulmonary Embolism].

OBJECTIVES: To determine the diagnostic value of CT venography after CT angiography of the pulmonary arteries using multislice helical CT in the diagnosis of acute pulmonary embolism. METHODS: Between September 1999 and April 2001 252 patients with clinically suspected pulmonary embolism were examined. CT angiography of the pulmonary arteries was followed by CT venography of the inferior vena cava, the iliac veins and the proximal femoral veins; after April 2000 the popliteal veins and the proximal lower leg veins were additionally investigated. The examinations were performed with a double detector and a multidetector scanner (Elscint Twin and GE Lightspeed). RESULTS: Pulmonary embolism was found in 79/252 patients (40 central and 39 segmental/subsegmental PE). In 38/40 patients with central PE and in 22/39 patients with segmental/subsegmental PE in CT venography a deep venous thrombosis was detected, in 1/79 patient a doubled inferior vena cava could be found. In 5 patients with thrombosis of the inferior vena cava a transjugular cava filter placement was performed. In 13/173 patients without pulmonary embolism CT venography showed deep venous thrombosis. CONCLUSION: CT venography of the lower extremities is a practical and efficient additional examination to CT angiography in clinical suspected pulmonary embolism. It can detect the causing venous thrombosis with a high sensitivity.
