3%), five strictures (26.3%) and a combination of both in nine cases (47.4%) when suturing the urethral anastomosis in a multilayer fashion including perineal muscle flaps to bolster the anastomosis.[12] In a series
of 31 free sensate osteofasciocutaneous fibula flaps and 6 RFF with prelaminated urethras, Schaff and Papadopulos presented 32.4% out of 37 cases involving urethral strictures and 16.2% (6 out of 37 cases) involving fistulas. Five out of the six fistulas originated at the connection site of the lengthened urethra to the prelaminated urethra.[8] In both our cases, urological complications occurred leading to open urethroplasties. Twelve months postoperatively, both patients were able to urinate through a competent TSA HDAC neo-urethra while standing. We do not think
that the occurrence of urological complications is related to the salvage-procedure but rather reflects the generally high incidence in phalloplasties. Sorafenib Donor-site morbidity after the RFF harvesting is considered a major drawback. Incomplete graft-take after donor site coverage with STSG or FTSG, functional impairment, prolonged swelling of the hand and sustained paresthesia in the hand, and neuroma formation have all been described.[15-17] Moreover, the scar on the forearm is frequently perceived as a stigma for transsexuals. In the presented cases, no donor-site complications or morbidities were encountered. The bilateral SSR128129E scars were not perceived as a major problem by either patient. Summarizing, in two cases of complete loss of the neo-urethra after total phalloplasty using a free sensate RFF in the Chang-design, we successfully salvaged the neo-urethra and reconstructed the outer lining of the neo-phallus using a second RFF. Twelve months postoperatively, both patients were able to urinate while standing. The aesthetic appearances were rated excellent and good, respectively. Sensitivity
was not impaired, as both patients reported an excellent tactile and erogenous sensitivity. In our experience, the presented technique is a valuable alternative to primary urethrostomy in such cases. It is clear that additional techniques for eliminating or at least mitigating partial flap necrosis as a major drawback of the standard tube-in-tube phalloplasty are needed. We propose the primary usage of a flap-in-flap technique, e.g. the combination of a free or pedicled sensate anterolateral thigh flap for neo-phallic construction and a free RFF or a pedicled groin flap for neo-urethral construction. Since only few reports on flap-in-flap approaches are presently available,[18, 19] the feasibility and safety of such a technique needs further assessment. “
“Free flap vascular pedicle avulsion represents an extremely rare complication in reconstructive microsurgery. Very few cases have been reported in the literature, most of them identified in free flap breast reconstruction.
