Stanol ester margarine alone and with simvastatin lowers serum cholesterol in families with familial hypercholesterolemia caused by the FH-North Karelia mutation.

In heterozygous familial hypercholesterolemia (FH), serum low density lipoprotein (LDL) cholesterol levels are already elevated at birth. Premature coronary heart disease occurs in approximately 30% of heterozygous untreated adult patients. Accordingly, to retard development of atherosclerosis, preventive measures for lowering cholesterol should be started even in childhood.

Heart transplantation in Finland 1985-1995.

Background And Aims: Since improved immunosuppression in the 1980's, heart transplantation is a well established procedure to treat patients with end-stage heart failure. The first heart transplantation in Finland was performed in 1985. Since then the activity has gradually increased to a level of about 25 annual transplants.

Effect of antiplatelet and anticoagulant therapy on patency of femorotibial bypass grafts.

In a retrospective study, 210 autogenous femorotibial saphenous vein grafts inserted during the 15 years from 1967 to 1982 were followed-up for a mean period of 62.3 +/- 5.7 months.

Diagnosis and treatment of subclavian artery aneurysms.

The diagnostic features and operative results in 13 patients with subclavian artery aneurysms were analysed. Symptoms related to subclavian artery aneurysms were present in seven patients, whereas six patients were asymptomatic and the aneurysm was discovered incidentally on chest X-ray. Angiography was the most valuable diagnostic examination and was also necessary in planning the operation.

Indications for and risks in reoperation for coronary artery disease.

Seventy-one coronary artery bypass grafting (CABG) reoperations were performed during a 17-year period, comprising 2.7% of all CABG operations. The main indication (in 87%) was vein graft failure alone or combined with other causes.

Polydioxanone in coronary vascular surgery.

We have used polydioxanone (PDS) in 50 patients who underwent coronary artery bypass grafting. The anastomoses consisted of suturing an autologous vein graft to the coronary artery (122 operations), a vein graft to the aorta (63 operations) and the internal mammary artery to the coronary artery (33 operations). The recipient coronary artery was subjected to endarterectomy in 28 instances.

Femorotibial bypass grafting for lower limb ischaemia.

The results of 305 femorotibial bypass grafts performed in 246 patients are presented. Of these operations 246 were primary and 58 secondary or tertiary. A total of 66 diabetic patients were in the series.

Femoral-tibial bypass for limb salvage.

From 1967 to 1982, 305 femoral tibial bypasses were performed. Of these 180 (59%) were performed on limb salvage indication. A reversed autogenous saphenous vein was used in 134 instances, among 46 vein substitutes there were 15 vein allografts, 13 human umbilical cord vein grafts, 12 PTFE grafts and six dacron grafts.

Surgical technique and operative mortality in coronary artery bypass. A postmortem analysis with castangiography.

Post-mortem analysis with castangiography was performed on 54 patients who died within 30 days of coronary artery bypass surgery. Myocardial failure was the cause of 85% of the deaths. There were 215 coronary anastomoses (4.

Popliteal artery entrapment.

External compression of the popliteal artery is probably still underdiagnosed. Young patients with atypical claudication, with isolated popliteal changes, deserve thorough investigation. Subdividing the entrapment syndrome into three subgroups (I-III) highlights the clinically important characteristics of the different types.

Primary tumours of the sternum.

In 1966-1986, two men and four women (mean age 47.5 years) underwent surgery for primary sternal tumour. Three of the tumours were benign (two condromata, one osteochondroma) and three were malignant (two chrondrosarcomata, one reticulum cell sarcoma).

Results of reoperations for coronary artery disease.

Seventy-one patients undergoing reoperation for coronary artery disease were examined on average 2.5 years postoperatively. Operative mortality was 9.

Management of vascular complications in thoracic outlet syndrome.

Arterial complications of thoracic outlet syndrome (TOS) were surgically treated in 11 patients (12 limbs) and venous complications in five (6 limbs). Arteriography showed total occlusion or significant stenosis of the subclavian artery in eight patients (bilateral in 1), with complicating peripheral thrombosis in three. Two patients had unilateral subclavian artery aneurysm: One was the patient with bilateral subclavian occlusion, and the other also had brachial artery embolism.

Primary tumours of the ribs.

Thirty-four primary rib tumours (24 benign, 10 malignant) were surgically treated in 1966-1985. The mean age was higher and the tumour diameter was greater in the patients with malignant, than in those with benign neoplasm. The benign tumours were excised without operative death.

Congenital arteriovenous fistulas in the chest wall.

The clinical manifestations of large congenital, haemodynamically significant arteriovenous fistulas in the chest wall, originating from the subclavian area, are described in three cases and the results of surgical treatment are reported. Symptoms related to arteriovenous shunting were present in all three, with precordial pain and/or cardiac dysrhythmia, dyspnoea and intermittent painful ischaemia of the upper extremity. Altogether 19 operations were performed.

Diagnosis and treatment of spontaneous aorto-caval fistula.

The diagnostic features and operative results of six patients with spontaneous aorto-caval fistula associated with abdominal aortic aneurysm were analyzed. Abdominal pain, pulsatile abdominal mass and haematuria were constant preoperative findings in all patients. Radiological signs of congestive heart failure of various degrees were present in five, abdominal bruit in four and preoperative renal failure in three patients.

Surgical treatment of occlusion of the infrarenal abdominal aorta. Experience with 55 patients.

A series of 55 patients with occlusion of the infrarenal abdominal aorta operated on in the 15-year period 1966-1980 is presented. The type of operation was an extra-anatomic reconstruction in four cases and some type of anatomic repair in 51 cases. The operative mortality was 5.

Constrictive pericarditis following coronary bypass reoperation. Fibrotic pericardium and a foreign body reaction.

A 65-year-old male patient underwent two bypass operations because of coronary artery disease. After the second operation he developed congestive heart failure with breathlessness, ankle swelling, hepatomegaly and poor exercise tolerance. Echocardiographic and haemodynamic findings were characteristic of constrictive pericarditis.

Traumatic rupture of the right hemidiaphragm.

Sixteen cases of traumatic disruption of the right hemidiaphragm are presented. Six tears were treated in the acute post-trauma phase and ten were detected from late manifestations. The causal trauma was penetrating in 11 cases and blunt in five.

Ruptured coronary artery aneurysm--a rare cause of hemopericardium.

Large coronary artery aneurysms may interfere with coronary flow, cause compression, and/or may rupture. Circulatory shock from thrombosis and rupture of an aneurysm of the right coronary artery in a patient is reported here. This formation, 7 cm in diameter, was visible by computed tomogram but the diagnosis was revealed only during surgery.

Epicardial lipoma.

A case of epicardial lipoma is presented. Coexisting coronary artery disease partly masked the symptoms by pointing to myocardial failure caused by compression from the tumor. An unexpectedly good result was achieved by combining excision of the lipoma with the planned coronary bypass procedure.

Isolated renal artery and combined aortic and renal artery reconstruction for renovascular hypertension. Late results of surgical treatment.

Fifty consecutive patients with renal artery occlusive disease underwent surgery for renovascular hypertension. The etiology was arteriosclerosis; only three patients had fibromuscular hyperplasia. Isolated renal artery stenosis was operated on in 22 patients while 28 patients underwent combined renal and aortoiliac/femoral procedures.
