Background. With greater experience in microsurgical reconstruction, free tissue transfer has become common and reliable. However, total flap necrosis after microsurgical reconstruction is sometimes seen in patients who have undergone radical ablation of head and neck malignancies. We investigated factors predicting free flap loss in head and neck reconstruction. Methods. We reviewed the records of 111 free flap reconstructions carried out among 107 patients with head and neck cancer who required radical resection and microsurgical reconstruction in our unit from 2004 through 2010. Among these patients, 6 showed total flap necrosis postoperatively. We investigated the associations between primary or recurrent tumor, type of flaps, chemotherapy, and radiotherapy and flap loss. Results. Five of 20 (25.0%) patients who underwent radiotherapy developed flap necrosis: among the 91 patient who did not undergo radiotherapy, only one (1.1%) developed. Preoperative radiotherapy was statistically identified as the most important risk factor for postoperative flap failure. Conclusions. Patients receiving radiation treatment are more likely to develop total flap failure when they undergo reconstructive surgery with free flaps after tumor ablation, because the combination of endarteritis and chronic ischemia caused by radiation damaged endothelial membrane in the recipient vessels, consequently, thrombosis tends to develop.

The Impact

Background This study was conducted to evaluate the impact of choosing a particular recipient venous system on venous patency and flap survival in 652 head and neck free flap reconstructions. Methods A retrospective review was performed. Patient factors investigated included: age, sex, type of flap, tumor location, history of radiation, presence of previous neck dissection, tumor stage, and any underlying disease. Data related with recipient vein including the number of anastomosis, the repair technique, the type of recipient vein, and the configuration of selected venous system were examined. The impact of patient factors and parameters related with recipient vein on the venous patency and flap survival were analyzed using bivariate and multivariate analyses. Results Of 652 free flaps, 36 flaps (5.5%) were re-explored due to venous congestion and 28 flaps (77.8%) were salvaged. The overall survival rate of total free flaps was 98.8%. The type of recipient venous system was found to be an insignificant factor with respect to venous congestion and flap survival in multivariate analysis. A history of radiation treatments was the only factor associated with a higher risk of venous compromise (odds ratio [OR] = 13.138, p < 0.001) and a lower rate of flap survival (OR = 20.182, p = 0.002). Conclusion The selection of recipient venous systems has no impact on venous patency and flap survival. History of radiation treatment was the only factor associated with venous congestion and flap failure. Since no single method can ensure a successful reconstructive result, selecting the optimal recipient vein should be based on individual patient factors and the surgeon's experience.

Background Due to limited evidence, it is unclear whether postoperative anticoagulation therapy may lead to higher success rates for microvascular free-flap surgery in the head and neck. This review evaluated whether postoperative anticoagulation therapy can lead to a better result in head and neck reconstruction. Methods PubMed, Embase, and the Cochrane Library were used to search for articles on the efficacy of postoperative antithrombotic therapy in free-flap transfer during head and neck reconstruction without language restrictions in February of 2017. A random-effects model was used to estimate the relative risk ratio (RR) with 95% confidence intervals (CIs). The measured outcomes were flap loss, thromboembolic events, and hematoma formation. Results A total of 2,048 free-flap surgery procedures in the head and neck were analyzed. There was no significant difference in the occurrence of flap loss and thromboembolic events in the anticoagulation group compared with the nonanticoagulation group (RR = 1.25, 95% CI = 0.85–1.81, p = 0.26; and RR = 1.05, 95% CI = 0.74–1.48, p = 0.79, respectively). The risk of hematoma was twice as high in the anticoagulation group than the nonanticoagulation group, which was statistically significant (RR = 2.02, 95% CI = 1.08–3.76, p = 0.03). Conclusion The findings from our meta-analysis indicate that postoperative anticoagulation therapy barely decreases the risks of flap loss and thromboembolic events in free-flap surgery in the head and neck. However, it may significantly increase the risk of hematoma formation. Considering the limitations of this meta-analysis, additional high-quality, multicenter, prospective, randomized controlled studies are needed to confirm these findings.

The use of free flaps is an essential and reliable method of reconstruction in complex head and neck defects. Flap failure remains the most feared complication, the most common cause being pedicle thrombosis. Among other measures, thrombolysis is useful when manual thrombectomy has failed to restore flap perfusion, in the setting of late or established thrombosis, or in arterial thrombosis with distal clot propagation. We report a case of pedicle arterial thrombosis with distal clot propagation which occurred during reconstruction of a maxillectomy defect, and was successfully treated with thrombolysis using recombinant tissue plasminogen activator. We also review the literature regarding the use of thrombolysis in free flap surgery, and propose an algorithm for the salvage of free flaps in head and neck reconstruction.

The Impact

Background Microvascular anastomotic patency is fundamental to head and neck free flap reconstructive success. The aims of this study were to identify factors associated with intraoperative arterial anastomotic issues and analyze the impact on subsequent complications and cost in head and neck reconstruction. Methods A retrospective review was performed on all head and neck free flap reconstructions from 2005 to 2013. Patients with intraoperative, arterial anastomotic difficulties were compared with patients without. Postoperative outcomes and costs were analyzed to determine factors associated with microvascular arterial complications. A regression analysis was performed to control for confounders. Results Total 438 head and neck free flaps were performed, with 24 (5.5%) having intraoperative arterial complications. Patient groups and flap survival between the two groups were similar. Free flaps with arterial issues had higher rates of unplanned reoperations (p < 0.001), emergent take-backs (p = 0.034), and major surgical (p = 0.002) and respiratory (p = 0.036) complications. The overall cost of reconstruction was nearly double in patients with arterial issues (p = 0.001). Regression analysis revealed that African American race (OR = 5.5, p < 0.009), use of vasopressors (OR = 6.0, p = 0.024), end-to-side venous anastomosis (OR = 4.0, p = 0.009), and use of internal fixation hardware (OR =3.5, p = 0.013) were significantly associated with arterial complications. Conclusion Intraoperative arterial complications may impact complications and overall cost of free flap head and neck reconstruction. Although some factors are nonmodifiable or unavoidable, microsurgeons should nonetheless be aware of the risk association. We recommend optimizing preoperative comorbidities and avoiding use of vasopressors in head and neck free flap cases to the extent possible.

Objective To investigate causes of failure of free flap reconstructions in patients undergoing reconstruction of head and neck defects. Study Design Case series with chart review. Setting Single tertiary care center. Subjects and Methods Patients underwent reconstruction between January 2007 and June 2017 (n = 892). Variables included were clinical characteristics, social history, defect site, donor tissue, ischemia time, and postoperative complications. Statistical methods used include univariable and multivariable analysis of failure. Results The overall failure rate was 4.8% (n = 43). Intraoperative ischemia time was associated with free flap failures (odds ratio [OR], 1.062; 95% confidence interval [CI], 1.019-1.107; P = .004) for each addition of 5 minutes. Free flaps that required pedicle revision at time of initial surgery were 9 times more likely to fail (OR, 9.953; 95% CI, 3.242-27.732; P < .001). Patients who experienced alcohol withdrawal after free flap placement were 3.7 times more likely to experience flap failure (OR, 3.690; 95% CI, 1.141-10.330; P = .031). Ischemia time remained an independent significant risk factor for failure in nonosteocutaneous free flaps (OR, 1.105; 95% CI, 1.031-1.185). Alcohol withdrawal was associated with free flap failure in osteocutaneous reconstructions (OR, 5.046; 95% CI 1.103-19.805) while hypertension was found to be protective (OR, 0.056; 95% CI, 0.000-0.445). Conclusion Prolonged ischemia time, pedicle revision, and alcohol withdrawal were associated with higher rates of flap failure. Employing strategies to minimize ischemic time may have potential to decrease failure rates. Flaps that require pedicle revision and patients with a history of significant alcohol use require closer monitoring.
