A carotic-subclavian bypass is an extraanatomical reconstruction. It is one of the possibilities how to connect the ipsilateral common carotid and subclavian artery. The authors evaluate carotic-subclavian bypasses made during the past 11 years at the Second Surgical Clinic in Brno. In all twelve cases carotico-subclavian bypasses were involved, in none of the patients a subclavian-carotid bypass was involved or direct anastomosis. The author discusses in detail preoperative complaints, associated diseases, postoperative complaints. In his opinion absolute indications for surgery are neurological symptomatic affections even of one trunk, incl. subclavian steal syndrome. They indicate asymptomatic affections for surgery if at least two trunks are affected. The greatest pitfall of the operation is in their opinion the selection of the length and type of vascular prosthesis. They find that the interval patency rate 100% and the cumulative patency rate 85% evaluated by the method of "Life table analysis" with a standard error of patency rate of 9% are comparable with similar reports from abroad.

INTRODUCTION: Cerebrovascular events are among the most common causes of invalidity or death. The aim of treatment in acute cerebral ischemia is to restore the blood flow before irreversible necrosis of brain tissue and persistent neurologic deficit occur. Pharmacological, endovascular and surgical methods are employed in the treatment of these patients. CASE REPORT: The authors present a case report of a 56-year-old woman with acute cerebral ischemia caused by tandem occlusion of the left common carotid artery and the M1 segment of middle cerebral artery. In the initial phase the patient was treated by intravenous thrombolysis with minimal success. Common carotid artery was occluded and mechanical extraction of embolus was successfully performed through direct carotid bifurcation puncture. Almost complete regression of neurologic deficit occurred after the endovascular recanalization. Occluded common carotid stump and bifurcation was considered as a source of embolization and therefore, to prevent further cerebrovascular event, a subclavian-carotid bypass was performed on the 15th day after the stroke. CONCLUSION: In the reported patient with symptomatic tandem occlusion of common carotid artery and the M1 part of middle cerebral artery, recanalization of cerebral artery was attained by the combination of pharmacological and endovascular method. Consequent subclavian-to-carotid bypass was performed in tertiary prevention of further cerebrovascular event.

Coronary subclavian steal syndrome (CSSS) is a well documented cause of graft function failure in patients after left internal mammary artery (LIMA)--left anterior descending (LAD) coronary artery grafting. We present a case of the CSSS in a patient with cardiac arrest due to ventricular fibrillation. To our knowledge such a case has not yet been described. Patient with a history of LIMA-LAD grafting, complaining only of a mild chronic exertional dyspnoea developed ventricular fibrillation while walking outdoor. After successful resuscitation, blood pressure difference between both arms and abnormal LIMA flow with systolic reversal flow on the Doppler ultrasonography were suggestive of CSSS. Angiography proved the left subclavian artery (LSA) occlusion and coronary angiography confirmed reversal flow in the LIMA graft. Successful percutaneous transluminal angioplasty of the LSA re-established normal LIMA flow and improved the left ventricular hypokinesis and systolic function.

A 77-year-old male former smoker with hypercholesterolemia and diabetes, who underwent coronary artery bypass graft surgery three years before admission and right carotid endarterectomy four years before admission, presented with recent-onset exertional chest pain. His medical history revealed that the chest pain was preceded by gradually worsening exertional claudication pain in his left arm when he was using crutches. The chest pain was similar to the pain he experienced before the coronary artery bypass graft surgery was performed. Coronary angiography and bypass graft imaging showed significant stenosis of the left subclavian artery proximal to the origin of the left internal mammary artery bypass, decreased flow in the left internal mammary artery with partial retrograde filling from the left anterior descending artery, and severe narrowing of the left vertebral artery with preserved centrifugal flow. Percutaneous stent implantation into the left subclavian artery was performed together with proximal balloon angioplasty of the left vertebral artery. The patient has been symptom free since the stent implantation.

The aim of this article is to summarize our experience in operations for subclavian steal syndrome. We recommend anaesthesia with preservation of patient's consciousness and mobility, and we prefer transposition of arteries to prosthesis implantation. The main characteristic of this approaches is an attempt to increase safety of operation. A feasible procedure is suggested also in the case of reconstruction occlusion: the axillo-axillary bypass. (Fig. 6, Ref. 3.)

INTRODUCTION: Aberrant right subclavian artery arising from the distal part of the aortic arch and passing behind the oesophagus (arteria lusoria) is a rare congenital vascular anomaly, it is the 4th most common aortic arch anomaly. At the site of the orifice there is the Kommerell's diverticulum, which is the locus minoris resistentiae with the possible arise of the aortic aneurysm. Aneurysmatic dilatation of the anomalous artery and of the aorta may be the cause of distal embolism or rupture. Less frequently there is also the possibility of aortic dissection or traumatic rupture. CASE REPORT: 54-old man with a symptomatic aberrant aneurysmatic dilated right subclavian artery (arteria lusoria) and an anerurysmatic dilatation of the Kommerell's diverticulum was indicated to staged combined management. Firstly we performed open surgical debranching of two supraaortic trunks (both subclavian arteries). Thereafter we excluded the orifice of the aberrant artery with the Kommerell's diverticulum by use of the endovascular techniques. There have been no complications during the perioperative period and the effect of surgery was optimal. DISCUSSION: It is generally accepted that the presence of aneurysm of the aberrant right subclavian artery is an indication for surgery, whether symptomatic or not. The conventional surgery is usually staged. Firstly there is a carotid-subclavian bypass or transposition on the right side and thereafter a transthoracic resection of the Kommerell's diverticulum and aortic angioplasty. The combined management with supraaortic revascularization followed with the stentgraft exclusion of the aneurysm is a sophisticated alternative. CONCLUSION: Experiences with the combined treatment published in the literature and ours are excellent, this technique is miniinvasive with a low complication rate. In our opinion it is the management of choice.

We report a case of 31 year old man with heterozygous familial hypercholesterolemia and excessive tobacco use leading to acute myocardial infarction as the first manifestation of premature atherosclerosis. The patvent was treated by primary PTCA of occluded first marginal artery and at this time an attempt of recanalisation of occluded LAD was unsuccessful. The patient was referred for mini coronary bypass graft of the LIMA to LAD. During evaluation of carotid arteries we found a significant stenosis of the left internal carotid artery and occlusion of the left subclavian artery which made the use of LIMA unsuitable. Therefore, another attempt of PTCA of the occluded LAD was performed, this time with success. Hence PTA of the occluded subclavian artery was performed with good result. The patient was treated with the standard therapy of CAD and combined lipid lowering agents with significant reduction of plasma cholesterol. However, 2 years after the first MI, he suddenly died after swimming at the age of 31. In this patient the risk of premature CAD was increased by the presence of another powerful risk factor--the excessive tobacco use. Acute physical exercise probably acted as a trigger of acute coronary events at the time of both MI. Interventional methods were very effective in the treatment of multiple atherosclerotic lesions in this patient and provided significant relief of symptoms. Treatment of heterozygous FH is briefly discussed in this article.
