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

Methodology: Twenty-four femoral veins of 12 fresh adult cadavers were dissected and photographed. Results: The diameter of the superficial, deep and common femoral veins was respectively 8.75 mm;7.60 mm and 13.95 mm. The common femoral vein was 80.70 mm long. At the level of the superficial vein, the modal disposition was noted in 79.17%;as anatomical variations, it was split in 2 cases, the presence of a collateral canal in 1 case and in 2, and it received a quadricipital muscle vein. At the level of the deep femoral vein, the modal disposition was noted in 16.67%, and the anatomical variations were noted in 83.33% where it received no affluent in the femoral trine. The modal disposition was noted in 91.67% at the level of the mode of birth of the common femoral vein, in 16.67% at the level of its tributaries. The anatomical variations were noted in 8.33% in the mode of birth of the femoral vein, in 83.33% in which the common femoral vein received, in addition to the large saphenous vein, other tributaries, the most frequent of which were the quadricipital veins and the circumflex femoral veins. Conclusion: The diameter of the femoral veins is important. The main tributaries of the common femoral vein are GVS, VQ and circumflex femoral veins. The femoral variations are numerous and important to know to avoid a possible misdiagnosis in case of their thrombosis.展开更多

The management of infectious pseudoaneurysm remainscontroversial.CASE SUMMARY We reported a 79-year-old man with previous Klebsiella pneumoniae pulmonaryinfection and multiple comorbidities who presented with a progressive pulsatemass at the right groin and with right lower limb pain. Computed tomographyangiography showed a 6 cm × 6 cm × 9 cm pseudoaneurysm of the right commonfemoral artery accompanied by occlusion of the right superficial femoral arteryand deep femoral artery. He underwent endovascular treatment (EVT) withstent–graft, and etiology of infectious pseudoaneurysm was confirmed. Then, 3-mo antibiotic therapy was given. One-year follow-up showed the stent–graft waspatent and complete removal of surrounding hematoma.CONCLUSION The femoral artery pseudoaneurysm can be caused by Klebsiella pneumoniaederiving from the pulmonary infection. Moreover, this unusual case highlights theuse of EVT and prolonged antibiotic therapy for infectious pseudoaneurysm.展开更多
