CAF is frequently diagnosed as an incidental finding. Herein, we present the case of a 4-year-old boy. He was referred for a pediatric cardiology assessment due to a continuous murmur at the middle sternal border. Echocardiogram showed dilated left coronary artery and an abnormal diastolic flow in the right atrium. The right-sided chambers were slightly enlarged, but ventricular contractility was normal. CAF was suspected. Angiography and CT confirmed the diagnosis of coronary fistula from the circumflex coronary artery to the right atrium. Successful transcatheter closure with an Amplatzer PiccoloOccluder was performed with complete occlusion.展开更多

Lateral Circumflex Femoral Artery(LCFA) isan important branch of Profunda Femoris artery and precise knowledge of its variations can be of great relevance during surgical and radiological procedures in femoral region. The present study reports a unique case of anomalous route taken by LCFA posterior to femoral nerve associated with a prominent muscular branch from Femoral artery mimicking the course of LCFA. Documentation of such variations is highly significant. It may serve as guideline for surgeons in reducing the incidence of postoperative complications where LCFA is used as a long vascular pedicle in anterolateral perforator thigh flap and in breast reconstruction after mastectomy. Ignorance of such variations can lead to fatal intraoperative haemorrhage and incapacitating sensory and motor deficit due to injury to femoral nerve branches which are closely related to these vessels.展开更多

It is an anatomical marker in direct anterior approach. As an important vessel around the hip joint,this vessel was ligated in most situations. Although ligation of the vascular pedicle of the LCFA is a common, traditional procedure used to decrease bleeding, the ligation of the pedicle of the vessel is tedious and time-consuming.AIM To explore whether this ligation is truly necessary in a direct anterior approach to total hip arthroplasty.METHODS This single-center, single-surgeon, prospective study was performed to compare patients' bleeding undergoing ligation of the branches of the LCFA pedicle(group A) vs those treated with electrocautery from the branches of the LCFA(group B). In both groups, the pedicles were identified in the intermuscular plane between the tensor fasciae lata and the rectus femoris muscles. In group A, the pedicles were ligated with a silk ligature. In group B, the branches coming off the LCFA were controlled with electrocautery. We compared preoperative vs postoperative changes in blood hemoglobin levels, intraoperative blood loss,operative time, rates of transfusion, re-bleeding, and hematoma between the two groups.RESULTS The reduction of hemoglobin in group A was 20.9 ± 7.0, and in group B it was 21.2 ± 4.9. There was no statistically significant difference between the two groups(P > 0.05). The actual calculated blood loss in group A was 784 ± 125 mL,and in group B it was 722 ± 153 mL. There was a trend in group A having more blood loss(P = 0.078). The estimated blood loss in group A was 344 ± 88 mL, and in group B it was 346 ± 73 mL. There was no statistically significant difference between the two groups(P = 0.883). In addition, there were no significant differences in the rates of postoperative transfusion(10% vs 6.7%, P > 0.05),postoperative hematomas(6.7% vs 13.3%, P > 0.05), or re-bleeding(13.3% vs 20%,P > 0.05) between the two groups.CONCLUSION Ligation of the pedicle of the LCFA has no advantage in preventing or decreasing bleeding during or after a total hip arthroplasty using the direct anterior approach. Ligation of the pedicle of the vessel is a cumbersome, unnecessary procedure and can be replaced by electrocautery control of the branches off this artery that course through the surgical field.展开更多

Most of the times it is an incidental finding detected at the time of a coronary angiography. However, sometimes it can have serious presentation like unstable angina, coronary steal or ventricular arrhythmia. We present a rare case of coronary cameral fistula arising from left circumflex artery (LCx) draining in to left ventricular (LV) apex and presenting as unstable angina.展开更多

Method 34 cases of femoral neck fracture had been treated with pedicle bone flap with deep iliac circumflex artery and canulate bone screws internal fixation. Result By follow up for 1 to 1.5 years, 32 cases were healing by first intention, and patients obtained satisfactory joint function. Conclusion Femoral neck fracture can be treated by transplanting pedicle bone flap with deep iliac circumflex vessel and canulate bone screws internal fixation.展开更多
