  • Microvascular reconstruction frequently requires anastomosis outside of the zone of injury for successful reconstruction. Multiple options exist for pedicle lengthening including vein grafts, arteriovenous loops, and arteriovenous bundle interposition grafts. The authors performed a systematic review of arteriovenous bundle interposition grafts to elucidate indications and outcomes of arteriovenous grafts in microvascular reconstruction. A systematic review of the literature was performed using targeted keywords. Data extraction was performed by two independent authors, and descriptive statistics were used to analyze pooled data. Forty-four patients underwent pedicle lengthening with an arteriovenous graft from the descending branch of the lateral circumflex femoral artery. Most common indications for flap reconstruction were malignancy (n = 12), trauma (n = 7), and diabetic ulceration (n = 4). The most commonly used free flap was the anterolateral thigh flap (n = 18). There were five complications, with one resulting in flap loss. Arteriovenous bundle interposition grafts are a viable option for pedicle lengthening when free flap distant anastomosis is required. The descending branch of the lateral circumflex femoral artery may be used for a variety of defects and can be used in conjunction with fasciocutaneous, osteocutaneous, muscle, and chimeric free flaps.

  • Although the etiology of $Kienb\"{o}ck's$ disease is clearly related to avascular changes in the lunate, but the actual cause leading to this vascular impairment has remained elusive. Therefore, a great many different surgical procedures have been proposed for the correction of the multiple factors leading to lunate collapse or for the treatment of the lunatomalacia. The treatment modalities includes lunate excision, intercarpal arthrodesis, lunate implant resection arthroplasty, joint levelling operation(e.g ulnar lengthening & radial shortening), pronater quadratus pedicle graft and vascular loop graft. In the period from Jan. 1981 to Dec. 1992, we performed operative treatment in 19 cases of $Kienb\"{o}ck's$ disease. Among them, 6 cases were treated with vascular loop graft. We analysed all patients who were treated with vascular loop graft after followed up of 4 year 6 months, on an average(range from 1 year to 8 year 10 months). The results analysed are as follows, 1. All cases were stage III according to Lichtman's classification. 2. Ulnar variance was -1.5(range$-2{\sim}0$), on an average. 3. The average age of patients were 37.7years old(range 31-41). 4. Postoperatively, there were considerable restoration of range of motion and complete relief of pain in all cases, but continued decrease of grip power in one case. 5. Decreased sclerosis, loss of fragmentation and new bone formation were appeared in the last follow up film, in all cases. The vascular loop graft considered as a useful method for the treatment of the $Kienb\"{o}ck's$ disease.
