A rationale is presented for extra-anatomic carotid cross-over bypass to maintain or restore blood flow to the internal carotid artery distal to sites of disruption and ligation of a common carotid artery. Anatomic evidence indicates that the attachment of the carotid sheath to the hyoid bone is a barrier to spread of infection cephalad to that level. A patient with infected and disrupted right common carotid artery associated with an esophageal fistula was treated by double ligation of the artery. Contralateral hemiplegia 48 hours later forced consideration of cerebral revascularization. Left carotid angiography demonstrated patent cerebral vessels on the right, with retrograde filling of the right internal carotid artery to the bifurcation. These findings were interpreted as consistent with technical feasibility of external carotid to external carotid cross-over vein bypass in a suprahyoid location, avoiding reconstruction in an infected area and resulting in prompt recovery of function.

Since 1959, 51 patients underwent open heart surgery for correction of an acute dissecting aneurysm of the ascending aorta. Upon admission, 33 patients were severely hypotensive or in progressive heart failure. Acute aortic insufficiency was found in 24 patients, and hemiplegia or hemiparesis in four. In 45 patients the ascending aorta was reconstructed with a woven Dacron graft. After excision of the dissected part of the aorta, primary anastomosis or patch aortoplasty was performed in six patients. The aortic valve remained intact in 26 patients, and resuspension of the commissures restored competence of the aortic valve in another nine. Sixteen patients required aortic valve replacement because of disrupture of the commissures. Dissection extended into the coronary ostia in nine cases. Reconstruction of the coronary system was accomplished by reimplantation of the ostia, interposition of a vein graft or aortocoronary bypass. Nine patients died within the early postoperative course from uncontrollable hemorrhage (four), further dissection (three) and myocardial infarction (two). Within the first year after surgery, another five patients died from acute aortic dissection (two), pseudomonas infection causing rupture of the proximal graft anastomosis (one) and myocardial infarction (two). Contraindications of antihypertensive treatment of acute dissection of the ascending aorta are discussed. We recommend prompt surgical intervention in acute dissecting aneurysms of the ascending aorta.

Fifty-eight adult patients treated with aortic valve replacement for infective endocarditis were retrospectively reviewed. The operation was performed during antibiotic therapy (group I, n = 25) or after completion of such therapy, on average 17 months after diagnosis (group II, n = 33). Preoperatively 68% of group I and 24% of group II were in NYHA class IV. Bacterial aetiology was verified in 78% of all cases. Preoperative embolic complications occurred in six group I and three group II cases, causing hemiplegia in eight. At operation the aortic valve was bicuspid in 29 of the 58 patients. Vegetations and cusp perforation were present in most cases. Bacteria were demonstrated in 11 of the excised specimens. A mechanical valve prosthesis was inserted in all cases. Three patients died, one perioperatively and two during their time in hospital (2 from group I). Low-output syndrome was the commonest postoperative complication. During follow-up averaging 66 months, 12 patients died (6 of cardiac causes). Late complications were periprosthetic leakage (2 cases), significant embolism (5), and prosthetic valve endocarditis (4), causing periprosthetic leakage in one case.

The incidence of neurological complications following operative treatment of concomitant occlusive disease of coronary and carotid arteries has been reported to be between 0.7 and 18 per cent by different preoperative screening methods and surgical strategy. From the opening of our institution in November 1984 until March 1988 5443 open-heart procedures were performed. In 116 patients of 3540 consecutive coronary artery bypass grafting (CABG) candidates simultaneous carotid endarterectomy (TEA) was carried out because of hemodynamically relevant stenosis of one or both carotid arteries; 50 patients were neurologically symptomatic with TIA's and amaurosis fugax preoperatively. Sixty of 66 patients with asymptomatic carotid artery stenosis had either a morphologically severe stenosis of the carotid artery or multifocal occlusive disease of the extracranial supraaortic arteries. Prior to carotid-TEA cardiopulmonary bypass was inserted with mild hypothermia maintaining a beating heart for pulsatile body perfusion. An intraluminal shunt was only used in patients with bilateral carotid stenosis. Intraoperative EEG-monitoring was carried out to detect cerebrovascular insufficiency. In 108/116 patients no neurological complications were observed, but 6/116 patients had transient minor neurological symptoms. Two of 116 patients sustained a severe neurological deficit with hemiplegia and one of them died on the 21st postoperative day. Based on these data we conclude that patients requiring carotid TEA and CABG should be operated upon simultaneously using cardiopulmonary bypass for both procedures.

The purpose of this study was to determine if a significant correlation exists between the side of hemiplegia caused by a cerebrovascular accident and side of a subsequent major lower-extremity amputation. We also attempted to determine if a relationship exists between the time from cerebrovascular accident to the amputation, or level of amputation, and any concomitant risk factors including diabetes mellitus, hypertension, heart disease, or cigarette smoking. Forty-seven patients were included in the study; 40 of the 47 had an amputation on the side of the hemiplegia, which represented a statistically significant relationship (chi 2 = 5.00, p less than 0.05). The cause of limb loss was chronic ischemia in all cases; trophic ulcers and pressure necrosis played a significant role in 23 cases. No conclusions could be made between the level of amputation or time between the cerebrovascular accident and amputation in relation to the presence or absence of diabetes mellitus, hypertension, heart disease, or cigarette smoking.

In the period between the opening of our heart center in November 1984 and May 1986, 2001 cardiac operations were performed with the aid of cardiopulmonary bypass. Almost three quarters (73.5%, n = 1471) of the patients had coronary artery disease and 20% (n = 359) had acquired valvular heart disease. In 47 of 1471 patients who underwent coronary artery bypass grafting, a simultaneous carotid endarterectomy was performed. They included 36 men and 11 women, aged between 51 and 78 years (mean 64 years). Preoperatively, 12 patients had cerebrovascular symptoms and 35 were neurologically asymptomatic. Twenty-three had unilateral carotid stenosis and 24 had bilateral or multiple vessel disease of the extracranial arteries. All except four patients had triple-vessel coronary artery disease. In three patients with aortic valve disease, coronary bypass, carotid endarterectomy, and aortic valve replacement were performed simultaneously. Cardiopulmonary bypass was instituted before carotid endarterectomy was performed, with mild hypothermia and hemodilution for added protection. Electroencephalographic monitoring was used throughout the operation. Forty-six of the 47 patients survived the operation without neurologic or cardiac complications. One patient had a neurologic deficit with hemiplegia and coma, which was lethal. We conclude that simultaneous endarterectomy of significant extracranial artery stenosis in candidates for coronary bypass is a method safe enough to justify its routine use.

The thoracic outlet syndrome is known to cause brachial neuropathy. Pressure on the subclavian artery causing post-stenotic dilatation with intraluminal thrombosis is not a common complication. This may lead to antegrade embolisation and ischemic changes in the upper limb. In right sided thoracic outlet syndrome the thrombus may extend retrogradely. From this an embolus may detach to the right hemisphere of the brain resulting in left sided hemiplegia. This is a rare but serious complication from a neglected, relatively benign, curable condition. This report describes two cases of a right sided thoracic outlet syndrome due to cervical rib compression with retrograde embolisation.

During the 20-year-period 1959-78, 7 patients with pulmonary arteriovenous fistula were treated at the Department of Thoracic and Cardiovascular Surgery. There were 5 men and 2 women, with a mean age of 26 (14-47) years. Cyanosis with elevated haematocrit was present in 4, dyspnoea in 4, neurological signs in 3 (including one brain abscess and one hemiplegia). Systolic hum was audible in 3 cases. Three patients had the hereditary type of the disease (Rendu-Osler-Weber) with telangiectasiae also elsewhere in the body. The calculated right-to-left shunt varied from 14 to 56 per cent of the cardiac output. The treatment was lobectomy in all cases (4 upper lobe, one middle lobe and 2 lower lobe resections). The patient with a brain abscess underwent craniotomy prior to lobectomy and developed epilepsy necessitating anticonvulsive treatment. The other patients had an uneventful recovery with relief of the symptoms. During the follow-up time (2-20 years), one patient (with hemiplegia) died of myocardial infarction 10 years after the operation. The others were doing well. It is concluded that the safest way to treat a pulmonary arteriovenous fistula is to operate as soon as it has been detected in order to prevent the complications so often associated with the disease.

Fibromuscular dysplasia of the internal carotid artery is the most frequent extracranial localization of the disease. It can produce TIA or cerebral infarct through formation of fibrinous thrombi or complete occlusion of the artery. Seven cases are presented with disease localized in the distal segment of the carotid artery, usually considered inaccessible through standard exposure. A surgical approach is described to treat these lesions by performing a mandible osteotomy. This allows a resection of the internal carotid and its replacement with autologous saphenous vein graft as performed in six cases. The distal anastomosis was performed 1 or 2 cm. below the base of the skull. One case could not be corrected due to disease extending into the skull. All patients were operated on for TIA and one had a cerebral infarct. Six patients had an uneventful recovery and no further neurological symptoms. One patient had a postoperative hemiplegia. Pathologic specimens were described as fibromuscular dysplasia in all cases. Three of them had also a dissecting aneurysm, two of these also showed a ruptured intima. Intraluminal dilatation is regarded as a potentially risky procedure; resection and replacement through a mandible osteotomy is recommended for very distal internal carotid lesions.

One hundred extrathoracic arterial reconstructions were performed on 98 patients with occlusions or stenoses of the subclavian or vertebral arteries: 52 bypasses, 18 transpositions of the subclavian artery to the common carotid artery, 13 endarterectomies and 17 operations involving two or more simultaneous reconstructions. The operative mortality was 1% (one patient). In 2 patients hemiplegia occurred as a complication of carotid-subclavian bypass operation. Six patients had a nerve injury as an operative complication: 1 lesion of the brachial plexus, 3 lesions of the recurrent nerve, and two lesions of the phrenic nerve (one patient also had Horner's syndrome). Immediate thrombosis of the operated arteries developed in 7 patients, 2 of whom were re-operated on. During the follow-up period (mean 4.5 years), six additional operations were performed because of failure of the first operation: the bypass graft was thrombosed in 5 of these cases and in one case a venous bypass graft with insufficient flow was replaced by a prosthesis. One patient underwent reconstruction of the contralateral side because of residual symptoms. In addition, 1 carotid endarterectomy, 2 thoracic sympathectomies, 4 coronary artery reconstructions and 8 lower limb arterial reconstructions were performed during the follow-up period. There were 17 late deaths, 9 of which were due to coronary artery disease. Of the 80 survivors 79% were satisfied with the operative result. The bypass was considered patent in 68%.
