  • A 33 year-old man was admitted with chief complaints of severe sharp pain on left upper interscapular region and motor weakness of left arm for 9 days. He had a history of blunt trauma over left shoulder about 3 years ago. Physical examination showed a ping pong ball sized mass which was located at the left supraclavicular area and was firm, fixed, and nonpulsatile. No bruit or murmur was obtained over the mass. Ipsilaterally, radial, ulnar, and brachial pulse were very weak and ptosis and anhidrosis were noticed. Neurologic examination revealed moderate or severe weakness of flexion and extension of left elbow, wrist and fingers, and anesthesia of the skin in left C8-T1 dermatome and hypalgesia in left C6-C7 dermatome. Retrograde aortography demonstrated complete obstruction of left subclavian artery. An exploratory operation was performed through the left 4th intercostal space. It was found that the mass was a left subclavian aneurysm of traumatic false type. Proximal and distal ligation of the aneurysm were applied and the sac was partially removed. The continuity of the subclavain artery was established by the use of a 6mm. Dacron graft from the root of the subclavian to the axillary artery. Postoperatively the patient was improved from the circulatory and neurologic disturbances.

  • A 57-year-old man with numbness and paresthesia of left arm is presented. There was no pulse in the left arm was absent and his chest radiograph suggested right-sided aortic arch. The aortogram showed right-sided aortic arch with Kommerell's diverticulum. The proximal portion of left subclavian artery was totally occluded and blood was being supplied through vertebral arteries to distal subclavian artery. He underwent bypass grafting between both subclavian arteries by an expanded polytetrafluoroethylene graft. Because the size of Kommerell's diverticulum was small, it need to be observed closely.

  • A case of complete interruption of aortic arch with aortopulmonary window, patent ductus arteriosus, and aberrantly originated right subclavian artery from proximal descending aorta, in a four year old boy is reported in detail. This is the only reported case in Korea, who has had a successful one-stage total anatomical correction of this combination of defects. Under deep hypothermia and total circulatory arrest, aortic continuity was established using patent ductus arteriosus and anterior wall of pulmonary artery, which was anastomosed obliquely to anteromedial side of ascending aorta. Aortopulmonary window was closed using Impra patch via pulmonary arteriotomy. Then pulmonary arteriotomy was reconstructed primarily except at the junction of right pulmonary artery and main pulmonary artery, where a small piece of pericardium was used to close the defect to prevent kinking and narrowing of right pulmonary artery. Postoperative cardiac catheterization demonstrated a good reconstruction.

  • The subclavian artery pseudoaneurysm in blunt trauma is uncommon and rarely occurs secondary to penetrating injury. Subclavian artery injuries represent an uncommon complication of blunt chest trauma, this structure being protected by subclavius muscle, the clavicle, the first rib, and the deep cervical fascia as well as the costo-coracoid ligament, a clavi-coraco-axillary fascia portion. Subclavian artery injury appears early after trauma, and arterial rupture may cause life-threatening hemorrhages, pseudoaneurysm formation and compression of brachial plexus. Most injuries were related to clavicle fracture, gunshot, other penetrating trauma, and complication of central line insertion. The presence of large hematomas and pulsatile palpable mass in supraclavicular region should raise the suspicion of serious vascular injury and these clinical evidences must be carefully worked out by physical examination of the upper limb. Since the first reports of endovascular treatment for traumatic vascular injuries in the 1993, an increasing number of vascular lesions have been treated this way. We report a case of subclavian artery pseudoaneurysm 10 days after blunt chest trauma due to traffic accident, treated by endovascular stent grafting.

  • Two groups of left pulmonary-subclavian artery anastomosis were done in 26 adult mongorel dogs. For the first group. the distal end of the subclnvian artery was nnastomosed to the side of the left pulmonary artery, and for the second group, the subclavian end wns anastomosed to the proximal end of the left lower lobe pulmonary artery. Among them, 6 died of bleeding or anesthetic failure during the day of operation, 10 survived 1 to 106 days and the other 10 were sacrificed at various interval. To investigate the relationship between hemodynamic stress and temporal evolution of the pulmonary vascular lesions. the pulmona try and femoral artery pressures, arteriogram and pathohistological specimens were obtained. The following results were obtained. 1. The postoperative pulmonary artery pressures were within normal limits except 2 dogs in the first group, but in nil 12 dogs of the second group, they were in moderate to maked pulmonary hypertension level. 2 After subclavian pulmonary anastomosis, both groups dogs showed increased femond artery pulse pressure. 3. The pulmonary vascular changes were more severe and appeared earlier in the second group dogs compared with the first group.4. The earliest vascular changes appeared in the media of the small muscular arteries and arterioles. 5. Various vascular chaDges were produced in 2 or 3 months. Thereafter, the changes were stationary. 6. Among the first group, two long-term servivors (No. 705 & 713) which had normal pulmonary artery pressure under the anesthesia, also showed various vascular changes as other pulmonary hypertensive dogs. 7. In the early stage medial hypertrophy. interruptio~l of elastic lamellae were found in the small muscular arteries and arterioles, which were followed by intimal proliferation and thrombosis. These findings may suggest some evidences of trauma to the vessels. 8. Pulmonary arteriograms showed irregularity of the intima of the large and medium sized arteries, abrupt ending of some of the small arteries and narrowing of the anastomosis.

  • This study was designed 1) to develop a hypertensive animal model in which the blood pressures (BPs) of symmetric regions (right and left upper extremities) are significantly different and 2) to test the effect of BP per se on the contractility and endothelium-dependent relaxation of vascular smooth muscle. Rabbits were anesthetized with sodium pentobarbital and ventilated with room air via animal respirator. The transverse aorta was exposed through the left second intercostal space and the lumen of the aorta was narrowed partially by ligation using 3-0 silk and a probe at a point between the origins of the brachiocephalic trunk and the left subclavian artery. Four to eight weeks postoperatively, BPs were measured in the carotid artery as the high BP area (proximal to coactation site) and in the femoral artery as the low BP area (distal to coarctation site). In the animal model, pressure-overload hypertension was developed and the BP of the right subclavian artery was higher than that of the left subclavian artery. The concentrations of circulating epinephrine, norepinephrine, angiotensin I, and angiotensin II were measured. The right and left subclavian arteries and their branches were used for isometric tension recording in organ baths and their responsiveness to phenylephrine, serotonin, acetylcholine, and sodium nitroprusside were examined. The BPs of carotid and femoral artery in control animals were $116{\pm} 12/75{\pm}9\;mmHg (mean ${\pm}SEM$) and $130{\pm}16/68{\pm}9\;mmHg$ respectively, while those of carotid and femoral artery in the hypetensive animals were $172{\pm}6/111{\pm}10\;mmHg$ and 136{\pm} 4/100 {\pm}9\;mmHg$ respectively. There were no significant differences in the concentrations of circulating epinephrine, norepinephrine, angiotensin I, and angiotensin II between controls and the animal models. No significant differences were found in the vascular sensitivities to phenylephrine and serotonin between the high pressure-exposed vessels and the low pressure-exposed vessels. However, the endothelium-dependent relaxation to acetylcholine and nitroprusside-induced relaxation showed significant differences between the high pressure-exposed and the low pressure-exposed subclavian arteries. From the above results, we suggest that the contractility of vascular smooth muscle is unchanged by the elevated pressure per se. However, the endothelium-dependent relaxation to acetylcholine and the nitroprusside-induced relaxation are attenuated by pressure.

  • From April 1990 through June 1990, three patients underwent subclavian flap aortoplasty for relief of the coarctation of the aorta. The age of the patients were 13 days, 7 months and 39 months and their weights were 3.3kg, 6.5kg, and 11kg, respectively. Two patients had persistence of the ductus arteriosus and all patients had associated intracardiac anomalies. We used the technique devised by Mendonca, namely, repair of the coarctation of the aorta using the subclavian artery as a flap and preservation of the arterial blood flow to the left arm. In one patient with long narrowing of isthmus, significant residual pressure gradient was remained by this technique and we added patch aortoplasty. There were no hospital deaths and follow-up over a one year period shows all patients in good condition.
