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.

We investigated the impact of preoperative ultrasonography of the forearm circulation on radial artery conduit selection. Preoperative ultrasound of the forearm circulation was performed routinely in 536 patients planned for radial artery harvesting. The safety assessment of the harvest included the following algorithm of tests: the ultrasound, the Allen test, and pulse oximetry. The quality criteria that were used to exclude a radial artery from harvesting were small size of the artery, diffuse atherosclerosis, calcifications, and severe neointimal hyperplasia. The overall rejection rate due to safety reasons was 16.4%. Seventy-one (13.2%) radial arteries did not fulfill the conduit quality criteria and consequently these arteries were not harvested. In 13.4% of radial arteries, localized arterial wall disease was found in the distal third of the artery. The distal part of the artery was discarded and the rest was used as a conduit. Our results indicate that the ultrasound provides an accurate preoperative insight into the radial artery morphology, enabling selection of the arteries with favorable morphological features.
