Arteriovenous malformations of the face and scalp are uncommon. We report a patient with facial AVM feeding from external carotid artery. This 26-year old man presented with an arteriovenous malformation involving left forehead. The patient first noted a coin-sized lesion on the site 20 years previously after blunt trauma which progressively enlarged. Surgical resection of AVM was performed after ligation of feeding artery.

The pulmonary sequestration is a rare congenital malformation of the lung, concerning about the abnormal feeding systemic artery, may happen a serious complication of bleeding during operation if not recognized before operation. We experienced a case of bilateral intralobar pulmonary sequestration preoperatively confirmed by aortogram. An Aortogram demonstrated a anomalous systemic artery arising from thoracic aorta just above the diaphragm. The artery bifurcated and supplied areas of both right and left lower lobes. On the operative field, left lower lobectomy was done with devision and ligation of left branch of anomalous artery and triple ligation of remained branch of anomalous artery was done. Postoperative course was uneventful. She was discharged on postoperative seventeenth day.

Bilateral coronary artery-pulmonary artery fistula is very uncommon congenital heart disease which occupy small percentage of all coronary arterio-venous fistulas. We experienced a case who was 52 years old female with bilateral coronary artery-pulmonary artery fistula. She complained exertional dyspnea k angina[coronary steal syndrome]. On physical examination, any cardiac murmur was not audible. There was no 0y step-up in right heart catheterization. But selective coronary angiography revealed tortuous aberrant vessels which originated from the canal branch of the right coronary artery k the left anterior descending coronary artery. Both aberrant vessels traversed the right ventricular outflow tract, and conjoined just proximal the pulmonic annulus and drained into the main pulmonary artery. The operation was performed under the extracorporeal circulation with beating heart. The procedures were suture-ligation of the draining orifice in main pulmonary artery & the feeding vessels on the right ventricular outflow tract. Postoperatively her complaints were completely disappeared and the selective coronary angiography revealed no left-to-right shunt.

To determine whether bile juice exclusion can prevent the mucosal damage, and Insulin-like growth factor-I can promote mucosal regeneration in ischemia-reperfusion injury of the bowel, 39 weanling rats with 10 cm of Thiry-Vella loop were studied. Animal groups were; Control, BL(common bile duct ligation), IGF{insulin-like growth factor-I(IGF-I) infusion} and IGF-BL(combined treatment). IGF-I(1.5 mg/kg/day) was continuously delivered through a subcutaneously implanted miniosmotic pump. After 15 minutes of superior mesenteric artery clamping, a tissue specimen(P) was taken after 30 minutes of reperfusion. Intestinal continuity was restored to allow oral feeding. A specimen of main tract(M) and another of the Thiry-Vella loop(T) were collected for histomorphometry after 48 hours of reperfusion and free feeding. Villus size ratio(VSR), crypt depth(CD), crypt-depth/villus-height ratio(CVR) and injury score(IS) were measured in 15 consecutive villi. The postoperative mortalities of bile duct ligation groups(BL and IGF-BL) were higher than those of other groups. In control group, VSR of M was lower(P<0.05) than P or T, but not in the other groups. VSR of M in control was lower than those in other groups. CD of T in control, IGF and IGF-BL group were higher than those of M. CD of M and T showed gradual increments from control, IGF and IGF-BL group, respectively. CVR of M and T in IGF group were higher than those in control. CVR in IGF-BL group, T was higher than M, and M was higher than P. About IS, M of BL($20.1{\pm}2.5$) and IGF-BL($20.9{\pm}3.3$) groups were significantly lower than that of control($32.4{\pm}2.5$). These results suggest that the exclusion of bile juice reduces the severity of the reperfusion injury of the mucosa, by inability to activate pancreatic enzymes and IGF-I stimulates mucosal regeneration in injured bowel, and the effect is potentiated by bile juice exclusion.

Arteriovenous malformations are vascular anomalies containing a communication between artery and vein without an intervening capillary bed and also are the most dangerous of vascular malformations being hemodynamically active. Treatment must be careful usually limited and considered in the phase of activity of hemodynamics. The patient was 29-year-old female and had no specific signs and symptoms except buldging, pal- pable mass on the right posterolateral chest wall from several years ago and it was gradually growing from that time. The operation was done with ligation of the right 9th, 1 Oth intercostal arteries and dissection from other normal tissues and then excised the arteriovenous malformation mass and its feeding vessels. The pathologic result was arteriovenous malformation.

Purpose: Autologous fat injection is ideal for patients who wish to add contour, projection and gross volumization of the aging, atrophic face and is claimed to be a safe procedure. However, there are several case reports in the literature where patients have suffered from acute visual loss and cerebral infarction after facial fat injection. This paper will explore a rare case of vessel related complication, an arteriovenous fistula that occurs after fat injection on forehead. Method: A 28 - year - old female who showed a non - tender, soft $1.0{\times}2.5cm$ sized mass on forehead for 3 weeks. A thrill could be detected on the totuous dilatated vessel - like structure around the mass. She had a fat injection on forehead for soft tissue augmentation 3 months prior to developing the mass. 3 - dimensional brain CT angiography showed arteriovenous fistula. Results: The fistula is totally excised with ligation of feeding vessels. Pathology report showed an atypical vessel which had intimal thickening, myxoid degeneration and thrombus formation. There were no evidences of recurrence at least for 2 months of follow - up. Conclusion: An occurrence of arteriovenous fistula after autologous fat injection is very rare. After perforation of artery and vein by coincidence, blood extravasates with the formation of a hematoma capsule and a pseudocapsule around it. The hematoma capsule would expand and clot would reabsorb resulting in a cavity leading to fistula formation. Other vessel related complications like acute visual loss or cerebral infarction are very severe. Therefore, surgeons should be cautious during facial fat injection to avoid vessel injuries.

This is a case report of an operation for the pulmonary arteriovenous fistula supplied from the systemic arteries instead of the pulmonary artery. The operation of systemic arteriovenous pulmonary fistula has formidable technical challenges due to its extensive collateral circulations. A 16 year-old female patient, diagnosed as systemic arteriovenous fistula with multiple tortuous feeding vessels and with hereditary hemorrhagic telangiectasia, was initially managed with arterial embolization before the operation. A 15${\times}$8cm sized huge vascular malformation was removed by RML and RLL bilobectomy. During the operation, we encountered annoying massive bleeding and pulmonary congestion originated in its extensive collateral circulation. The patient was discharged after conservative management without specific problem on the 15th postoperative day. For the safe operation as well as good operative result, it seemed that meticulous ligation of the multiple collateral vessels should be performed prior to that of pulmonary veins.
