Abstract. Hypothenar or thenar hammer syndrome (HHS) and hand-arm vibration syndrome (HAVS) are diseases caused by acute or chronic trauma to the upper extremities. Since both diseases are generally related to occupation and are recognised as occupational diseases in most countries, vascular physicians need to be able to distinguish between the two entities and differentiate them from other diagnoses. A total of 867 articles were identified as part of an Internet search on PubMed and in non-listed occupational journals. For the analysis we included 119 entries on HHS as well as 101 papers on HAVS. A professional history and a job analysis were key components when surveying the patient’s medical history. The Doppler-Allen test, duplex sonography and optical acral pulse oscillometry were suitable for finding an objective basis for the clinical tests. In the case of HHS, digital subtraction angiography was used to confirm the diagnosis and plan treatment. Radiological tomographic techniques provided very limited information distal to the wrist. The vascular component of HAVS proved to be strongly dependent on temperature and had to be differentiated from the various other causes of secondary Raynaud’s phenomenon. The disease was medicated with anticoagulants and vasoactive substances. If these were not effective, a bypass was performed in addition to various endovascular interventions, especially in the case of HHS. Despite the relatively large number of people exposed, trauma-induced circulatory disorders of the hands can be observed in a comparatively small number of cases. For the diagnosis of HHS, the morphological detection of vascular lesions through imaging is essential since the disorder can be accompanied by critical limb ischaemia, which may require bypass surgery. In the case of HAVS, vascular and sensoneurological pathologies must be objectified through provocation tests. The main therapeutic approach to HAVS is preventing exposure.

Abstract. Background: The aim of this prospective single-centre study was to analyse the immediate results, failures and complications of percutaneous mechanical thrombectomy using the Rotarex catheter in the treatment of acute and subacute occlusions of peripheral arteries and bypasses, as well as to evaluate long-term outcomes of this method. Patients and methods: Patients with acute (duration of symptoms < 14 days) or subacute (duration of symptoms > 14 days and < 3 months) occlusions of peripheral arteries and bypasses were selected consecutively for treatment. The cohort consisted of 113 patients, aged 18 - 92 years (median 72 years). In all, 128 procedures were performed. Results: Angiographic success was obtained in 120 interventions (93.8 %). Reasons for failures were rethrombosis of a partially recanalised segment in six procedures, and embolism into crural arteries in one intervention - percutaneous aspiration thromboembolectomy (PAT) and/or thrombolysis were ineffective in all these cases. Breakage of the Rotarex catheter happened in one procedure. Embolisation into crural arteries as a transitory complication solvable with PAT and/or thrombolysis occurred in four cases. Rethrombosis was more frequent in bypasses than in native arteries (p = 0.0069), in patients with longer occlusions (p = 0.026) and those with poorer distal runoff (p = 0.048). Embolisation happened more often in patients with a shorter duration of symptoms (p = 0.0001). Clinical success was achieved in 82.5 %. Major amputation was performed in 10 % of cases. Cumulative patency rates were 75 % after one month, 71 % after six months, 38 % after 12 months, 33 % after 18 months and 30 % after 24, 30, 36 and 42 months. Conclusions: Rotarex thrombectomy has excellent immediate results with a low rate of failures and complications. In comparison to thrombolysis, it enables the fast and efficient treatment of acute and subacute occlusions of peripheral arteries in one session.

Summary Objective: The goal of the study was to assess the effectiveness and patient tolerability of single-session, sonographically guided, transcatheter foam sclerotherapy and to evaluate its economic impact. Patients, methods: We treated 20 patients with a total of 22 varicoses of the great saphenous vein (GSV) in Hach stage III-IV, clinical stage C2-C5 and a mean GSV diameter of 9 mm (range: 7 to 13 mm). We used 10 ml 3% Aethoxysklerol®. Additional varicoses of the auxiliary veins of the GSV were sclerosed immediately afterwards. Results: The occlusion rate in the treated GSVs was 100% one week after therapy as demonstrated with duplex sonography. The cost of the procedure was 207.91 E including follow-up visit, with an average loss of working time of 0.6 days. After one year one patient showed clinical signs of recurrent varicosis in the GSV; duplex sonography showed reflux in the region of the saphenofemoral junction in a total of seven patients (32% of the treated GSVs). Conclusion: Transcatheter foam sclerotherapy of the GSV is a cost-effective, safe method of treating varicoses of GSV and broadens the spectrum of therapeutic options. Relapses can be re-treated inexpensively with sclerotherapy.

SummaryWe investigated the vessel status of coronary and peripheral arteries and those arteries supplying the brain in 929 consecutive male patients admitted to a coronary rehabilitation unit. The severity of coronary atherosclerosis was scored using coronary angiography. Changes in extracranial brain vessels and manifest cerebrovascular disease (CVD) were determined by B-mode ultrasound and Doppler examination. Peripheral arterial disease (PAD) was diagnosed using base-line and stress oscillography. We assessed variables of coagulation, fibrinolysis, and the acute phase response.There was a significant increase in plasma fibrinogen, plasminogen, d-dimer and C-reactive protein (CRP) with increasing severity of coronary heart disease. Compared to men with unaffected arteries, men with 3 diseased coronary arteries had 58% greater d-dimer concentrations. Patients with CVD and PAD, respectively, also had significantly higher fibrinogen, d-dimer and CRP concentrations. We did not find an association between plasminogen activator inhibitor activity and the severity of coronary atherosclerosis.In conclusion, plasma fibrinogen, d-dimer and CRP concentrations were significantly related to atherosclerosis in the coronary, peripheral and extracranial brain arteries.
