A 59-year-old man without a history of ischemic heart disease underwent elective laparoscopic cholecystectomy under general anesthesia with epidural anesthesia. About 15 min after pneumoperitoneum had been achieved, the patient developed ST elevation and hypotension. Vagal stimulation resulting from stretching peritoneum, the procedure and epidural anesthesia are thought to have induced vasospasm. The ST segment became normal after interruption of CO2 insufflation. A postoperative coronary artery angiogram showed normal coronary arteries, but diffuse coronary artery spasm was seen after intracoronary injection of acetylcholine. The patient was discharged on nitrates. Patients with gall bladder stones sometimes have coronary risk factors of obesity, hyperlipidemia and hyperglycemia. Careful attention should also be given to patients who do not have a history of coronary disease.

A 45-year-old patient with von Gierke disease was scheduled for emergency operation due to acute appenditis. He had a significant hepatomegaly and was on oral medication for hyperlipemia and hyperlithuria. General anesthesia was induced with thiopental and suxamethonium, and maintained with nitrous oxide, oxygen, sevoflurane and vecuronium. The perioperative course was uneventful, although the patient revealed mild metabolic acidosis.

Glycogen storage disorder type 1A (GSD 1A) is an inherited disorder of glycogen metabolism characterized by fasting hypoglycemia, lactic acidosis, hyperuricemia, and hyperlipidemia. These children have a higher risk of developing pancreatitis because of hypertriglyceridemia. Drug-induced pancreatitis accounts for a small proportion of cases of pancreatitis. The mechanism of drug-induced pancreatitis include hypersensitivity, direct toxic injury or indirectly by inducing hypertriglyceridemia. Propofol is often the drug of choice for induction of anesthesia in ambulatory surgical procedures. There are various reports in the literature describing pancreatitis induced by propofol. We present a 4-year-old girl with GSD 1A, who required tonsillectomy and adenoidectomy under general anesthesia. She developed acute pancreatitis in the postoperative period. Propofol was used as a general anesthetic and the postoperative incidence of pancreatitis is discussed.

The clinical features of propofol infusion syndrome (PRIS) are acute refractory bradycardia leading to asystole, in the presence of one or more of the following: metabolic acidosis (base deficit > 10 mmol.l(-1)), rhabdomyolysis, hyperlipidaemia, and enlarged or fatty liver. There is an association between PRIS and propofol infusions at doses higher than 4 mg.kg(-1).h(-1) for greater than 48 h duration. Sixty-one patients with PRIS have been recorded in the literature, with deaths in 20 paediatric and 18 adult patients. Seven of these patients (four paediatric and three adult patients) developed PRIS during anaesthesia. It is proposed that the syndrome may be caused by either a direct mitochondrial respiratory chain inhibition or impaired mitochondrial fatty acid metabolism mediated by propofol. An early sign of cardiac instability associated with the syndrome is the development of right bundle branch block with convex-curved ('coved type') ST elevation in the right praecordial leads (V1 to V3) of the electrocardiogram. Predisposing factors include young age, severe critical illness of central nervous system or respiratory origin, exogenous catecholamine or glucocorticoid administration, inadequate carbohydrate intake and subclinical mitochondrial disease. Treatment options are limited. Haemodialysis or haemoperfusion with cardiorespiratory support has been the most successful treatment.

Endovascular angioplasty for subclavian artery stenosis is effective and less invasive than other methods; however, it is difficult to advance guidewires or balloon catheters through severely stenotic lesions. We report a case of subclavian artery stenosis treated with excimer laser angioplasty. A 58-year-old man with hypertension and hyperlipidemia was admitted to a hospital with different blood pressure in each arm. A CT scan revealed left subclavian artery stenosis, and the patient was transferred to our hospital. An angiogram revealed a severely stenotic lesion in his left subclavian artery, representing subclavian steal phenomenon. Endovascular angioplasty was performed under local anesthesia with embolic protection for the left vertebral artery. The guidewire successfully crossed the lesion, and stepwise balloon angioplasty was performed using increasing balloon sizes from 1.5 to 2.0 mm; however, the next size balloon catheter could not cross the lesion, and we therefore decided to use an excimer laser catheter. After laser ablation, revascularization was performed via stent placement. The patient's symptoms and subclavian steal phenomenon improved, and the post-operative course was uneventful. Excimer laser angioplasty appears to be effective in the treatment of occlusive lesions that cannot be crossed using a balloon catheter.

To assess the influence of hyperlipidemia (HL) on amiodarone (AM) effect in the heart, rats were pretreated with either 1 g/kg poloxamer 407 (to induce HL) or saline intraperitoneally. At approximately 36 hours afterward, rats were given AM HCl (25, 50, and 100 mg.kg.d) or saline intravenously through implanted venous cannulas for 5 days. Under anesthesia, electrocardiogram (ECG) was recorded using subcutaneous electrodes and blood samples were withdrawn at baseline and 12 hours after the first, middle, and last doses. At the end of the study, heart tissues were collected. Specimens were analyzed for AM and desethylamiodarone. HL by itself did not alter the ECG. Compared with baseline, the end of study prolongation of QTc and PR intervals were significantly (P < 0.05) higher in all AM-treated HL rats. AM plasma and heart concentrations in HL rats after the last dose were significantly (P < 0.05) higher than in normolipidemic rats. Similar to AM, in HL rats, plasma desethylamiodarone after the last dose was significantly higher than in normolipidemic rats. The cholesterol to triglyceride plasma ratio was linearly related to QT interval and plasma and heart AM concentrations. HL increased the ECG effects of AM by increasing heart concentrations.

Well leg compartment syndrome is rare after laparoscopic radical prostatectomy. We report a 68-year-old man that developed compartment syndrome after laparoscopic radical prostatectomy for prostate cancer. There are several circumstantial risk factors associated with LRP that, when combined, may potentially predispose to the development of compartment syndrome, including: obesity, evidence of peripheral vascular disease (advanced age, hypertension, hyperlipidemia, and diabetes mellitus), thromboembolism prophylaxis with compressive leg wraps together with intermittent pneumatic devices, combined general-spinal anesthesia, prolonged operative time in Trendelenburg position, and systemic hypotension due to intraoperative bleeding. The pathogenesis of this serious complication is discussed and preventive measures are highlighted.

Published data suggest that the regional anesthetic technique used for carotid endarterectomy (CEA) increases the systolic arterial blood pressure and heart rate. At the same time local anesthesia reduced the shunt insertion rate. This study aimed to analyze risk factors and ischemic symptomatology in patients with postoperative internal carotid artery restenosis. The current retrospective study was undertaken to assess the results of CEA in 8000 patients who were operated during a five-year period in six regional cardiovascular centers. Carotid color coded flow imaging, medical history, clinical findings and atherosclerotic risk factors were analyzed. Among them, there were 33 patients (0.4%) with postoperative re-occlusion after CEA. The patients with restenosis were re-examined with carotid color coded flow imaging and data were compared with 33 consecutive patients with satisfactory postoperative findings to serve as a control group. In the restenosis group eight risk factors were analyzed (hypertension, smoking, hyperlipidemia, diabetes mellitus, history of stroke, transitory ischemic attack, heart attack and coronary disease), and compared with risk factors in control group. Study results suggested that early postoperative internal carotid artery restenosis was not caused by atherosclerosis risk factors but by intraoperative shunt usage.

A 66-year-old man with a history of longtime smoking, untreated hypertension, hyperlipidemia, and impaired glucose tolerance but no history of myocardial infarction or angina pectoris was scheduled for right aortofemoral bypass and thromboembolectomy for arteriosclerosis obliterans with right common iliac and right popliteal arterial thrombus. Epidural anesthesia and general anesthesia were administered without obvious ECG changes. Just after skin incision, ST elevation in leads II and V5 and a short run of ventricular tachycardia with frequent premature ventricular contractions (PVCs) were recorded on the ECG monitor, and the patient's blood pressure suddenly decreased within a few seconds. On noticing these changes, we suspected coronary artery spasm (CAS) and rapidly administered vasodilators and vasopressors to stabilize hemodynamics and ECG changes. Transesophageal echocardiography (TEE) showed basal to mid- and anteroseptal to inferior wall motion hypokinesis that gradually returned to normal during observation. Even in patients without coronary disease but with systemic arteriosclerosis, it is important to consider the possibility of perioperative CAS and not to overlook ECG changes. Immediate diagnosis and treatment are essential.

The development of new propofol formulations has advanced rapidly in the last ten years with the achievement of the marketing a new prodrug of propofol: fospropofol, pharmacologically different from the original compound. It is a water soluble compound that requires metabolism of the prodrug to propofol, which leads to a time delay between its administration and the appearance of its pharmacological effect. Its pharmacokinetic and pharmacodynamic characteristics are different to the original formula. Due to its formulation it does not cause pain on intravenous injection, does not lead to hyperlipidaemia or excess bacterial growth. Although it is currently unavailable in Spain, it has been approved by the FDA (American Food and Drug Administration) for sedation in controlled care in diagnostic and therapeutic procedures in adults. It must only be administered by personnel qualified to administer anaesthesia, and the patients must be monitored throughout the whole procedure.
