Objective To evaluate repair and reconstructionof the femoral pseudoaneurysm caused by drug injection. Methods From May 2000 to May 2005, 15 cases of femoral pseudoaneurysm caused by drug injection underwent operation treatment. All patients were male, aging 20-36 years. The disease course was 18-52 days(mean 35 days) and the course of druginjection was 3-17 months. The locations were the left side in 5 cases and theright side in 10 cases. After having been bandaged with pressure and supportedwith nutrition, they had been all operated. One case received fistula repair, and 14 cases received vascular grafting with ePTFE man-made blood vessel. Results The wounds healed by the first intention in 14 cases. All limbs survived. The complexion, temperature and response of involved leg were in gear. The postoperative color ultrasound Doppler detection showed that all the vascular grafts were of patency. The function of the involved limbs restored to normal. Conclusion Complete debridement, vascular reconstruction and better microsurgery skill were the key factors of treating successfullythe femoral pseudoaneurysm caused by drug injection.
Objective To explore the outcome of hypopharynx reconstruction by using remaining laryngeal mucosa flap and pectoralis major myocutaneous flap in advanced pyriform sinus cancer.Methods Twelve patients with pyriform sinus cancers underwent hemilaryngectomy and partial pharyngectomy, two patients underwentcervical esophagectomy at the same time. The defects were reconstructed by remaining laryngeal mucosa flap. Four cases were involved in the bilateral larynx, received total laryngectomy and were repaired by pectoralis major myocutaneous flap. Results There was no operative fatal case and all flaps survived. Only one suffered from postoperative pharyngocutaneous fistulas, whose defect was reconstructed by remaining laryngeal mucosa flap and had radiotherapy. All patients could swallow ordinary food and had no benign esophagostenosis and pharyngostenosis after operation. Out of 16 pateints, 1 case died of general metastasis;3 cases died of local tumor relapse, tumor relapse of cervical lymphonode and lung metastasis respectively within 1 year after operation; the other 12 casessurvived over 2 years.Conclusion The advantage of hypopharynx reconstruction with remaining laryngeal mucosa flap is simple and convenient with less trauma and complication. The reconstruction should be completed by using the pectoralis major myocutaneous flap when the bilateral larynx are involved in.
