We present a successful surgical treatment of a 75x70mm circumflex coronary artery pseudoaneurysm detected incidentally in a 48-year-old male patient. Successful correction was made by repairing the fistulized area in the left atrium and the ‘neck’ in the pseudoaneurysm.

Artery Disease

<P>Background: Hypoplastic coronary artery disease is a rare congenital coronary artery anomaly. It is often detected incidentally, and its true incidence in the general population is not known. </P><P> Discussion: Symptoms of HCAD are syncope, palpitations, dyspnea, and chest pain. Also, arrhythmia and myocardial infarction can be seen; these can cause sudden death, especially in athletes and young people. Diagnosis is often made at autopsy. Conclusion: Here, we present the case of a 39-year-old male with isolated hypoplasia of the left circumflex artery detected by coronary Computed Tomography (CT) angiography who complained of palpitation.</P>

Collateral Development

To study the effects of exercise on collateral development in myocardial ischemia, we induced coronary arterial stenosis of the left circumflex coronary artery (LCCA) in 18 of 30 pigs. During that surgery, we identified the coronary bed at risk. Nine of these pigs were then subjected to 5 mo of exercise training on a treadmill. After exercise training, we determined regional collateral and myocardial blood flow using radiolabeled microspheres. At autopsy, all animals had complete occlusion of the LCCA. Infarct size in the exercise-trained pigs was significantly less than in the sedentary pigs (5.9 +/- 1.0 vs. 11.7 +/- 1.0% of the left ventricle). The exercise-trained animals had a greater increase in collateral flow, 35.1 +/- 3.0 vs. 28.7 +/- 4.1 ml X min-1 X 100 g-1, in the noninfarcted jeopardized zone of the LCCA bed. The major findings of the study were the following: 1) chronic coronary artery stenosis progressing to occlusion stimulated development of the collateral circulation and salvaged tissue in the jeopardized myocardium of an animal model with sparse collaterals; 2) development of the collateral circulation and tissue salvage is increased by exercise training; 3) collaterals develop primarily in or near the ischemic zone; and 4) all collateral beds develop a circumferential flow gradient following occlusion.

Persisting coronary vasoconstrictor tone that is responsive to exogenous adenosine administration has been demonstrated during myocardial ischemia. Therefore, the role and extent of endogenous adenosine-mediated coronary vasodilation in opposing coronary vasoconstriction within regions of ischemic myocardium was investigated in 10 chronically instrumented exercising dogs. Studies were performed on dogs with left circumflex coronary artery stenosis during treadmill exercise (6.5 km/h, 6% grade), while myocardial blood flow was measured with radioactive microspheres. Blood flow was measured before and again after inhibition of the effects of endogenously produced adenosine through combined inactivation of adenosine and adenosine receptor antagonism by the administration of intracoronary adenosine deaminase (ADA) (5 micrograms.kg-1 x min-1 x 10 min) plus 8-phenyltheophylline (8-PT) (5 mg/kg i.v.), respectively. Coronary perfusion pressure was held equal during both conditions at approximately 41 mmHg with a hydraulic occluder. During exercise in the presence of a coronary stenosis, blood flow was reduced in all layers of myocardium in regions supplied by the stenosed left circumflex coronary artery compared with blood flow in regions of myocardium supplied by the nonstenotic left anterior descending coronary artery. After ADA plus 8-PT, myocardial blood flow (in ml.min-1 x g-1) was further reduced in all layers of myocardium in regions supplied by the stenotic left circumflex coronary artery compared with baseline (subendocardial layer 0.44 +/- 0.09 vs. 0.67 +/- 0.13 ml.min-1 x g-1, mean transmural flow 0.92 +/- 0.13 vs. 1.25 +/- 0.2 ml.min-1 x g-1, both P < 0.05). Blood flow in regions of myocardium supplied by the nonstenotic left anterior descending coronary artery were unchanged following ADA plus 8-PT.(ABSTRACT TRUNCATED AT 250 WORDS)

Superficial Tumor

Dermatofibrosarcoma protuberans is a rare superficial tumor characterized by high rates of local recurrence and low risk of metastasis. Dermatofibrosarcoma protuberans occurs most commonly on the trunk and proximal extremities, it affects all races, and often develops between the second and the fifth decade of life. The tumor grows slowly, typically over years.We present a rare case of a young male patient, 21 years old, with an asymptomatic calf tumor which was suspected to be an angioma, but after the initial excision histology and imunohistochemistry proved to be a Dermatofibrosarcoma protuberans without safety limits. After 2 weeks, we excised the remaining scar with 4 cm tissue limit and the defect was covered using an adipofascial reversed sural flap from the posterior part of the left calf and after another 2 weeks we applied a skin graft from the thigh.The patient had a good evolution, with full recovery, without local recurrences or metastasis, and the histology was within good safety limits.
