Ipsilateral carotid bypass outcomes in hostile neck anatomy.

OBJECTIVE: To determine differences in outcomes among patients undergoing ipsilateral carotid bypass with hostile or normal neck anatomy. METHODS: Single-center retrospective review of all ipsilateral extracranial carotid bypasses performed between 1998 and 2018. RESULTS: Forty-eight patients underwent ipsilateral carotid bypass from the common carotid artery to either the internal carotid artery or carotid bifurcation during the study period. Seven patients were excluded owing to either a lack of follow-up or missing data. The indications for intervention included infected patches, aneurysmal degeneration, symptomatic and asymptomatic stenosis or restenosis, carotid body tumors, neck malignancy, and trauma. In 25 procedures (61%), there was a hostile neck anatomy defined as a prior history of external beam neck irradiation or neck surgery. Among this group, 12 pectoralis muscle flaps were performed for reconstructive coverage. Conduits included polytetrafluorethylene (n = 21), great saphenous vein (n = 9), superficial femoral artery (n = 7) and arterial homograft (n = 4). All superficial femoral artery conduits were used in the hostile neck group (P = .03). The overall mean time of follow-up was 22 months, with all bypasses remaining patent with no significant clinical stenosis. The 30-day ipsilateral stroke and myocardial infarction rates were 4.88% each, all within the hostile neck group, with no 30-day mortalities for the entire cohort. One-third of the muscle flaps were performed in the setting of infected patches (P = .02) with no significant differences in perioperative outcomes with use. The overall median hospital length of stay was significantly increased in patients receiving muscle flap coverage (3.0 vs 7.0 days; P = .04). CONCLUSIONS: In patients with a complex carotid pathology, ipsilateral carotid bypass is an effective solution for carotid reconstruction. Different conduits should be used depending on the indication. Muscle flap coverage should be considered in hostile settings when primary wound closure is not feasible.

Reconstruction of Large Area of Deep Wound in the Foot and Ankle with Chimeric Anterolateral Thigh Perforator Flap.

OBJECTIVE: To evaluate the clinical application and surgical efficacy of the chimeric perforator flap pedicled with the descending branch of the lateral circumflex femoral artery and the lateral thigh muscle flap for the reconstruction of the large area of deep wound in foot and ankle. METHODS: Clinical data of 32 cases who underwent chimeric anterolateral thigh perforator flap to repair the large area of deep wound of the foot and ankle from January 2015 to December 2018 were retrospectively analyzed. The sizes of the defects ranged from 18 cm × 10 cm to 35 cm × 20 cm, with exposed tendon and bone and/or partial defects and necrosis, contaminations, accompanied by different degrees of infection. Following the radical debridement and VSD, chimeric anterolateral thigh perforator flap was employed to repair the deep wounds according to the position, site and deep-tissue injury of the soft-tissue defects. The skin flap and muscle flap were fanned out on the wound, and single- or two-staged split-thickness skin grafting was performed on the muscle flap. The operation time and blood loss were recorded. The survival and healing conditions of the operational site with chimeric anterolateral thigh perforator flap were evaluated post-operationally. Complications at both recipient site and donor site were carefully recorded. RESULTS: The mean time of the operation was 325.5 min and average blood loss was 424.8 mL. Among the 32 cases, two cases developed vascular crisis, which were alleviated with intensive investigation and treatment; Four cases suffered from partial necrosis of the flap or skin graft on the muscle flap or on the residual local wound, which were improved after treatment of further dressing change and skin grafting. Another four cases experienced post-traumatic osteomyelitis accompanied by bone defect were treated with simple bone grafting or Mesquelet bone grafting at 6-8 months after wound healing. Postoperatively, the wounds were properly healed, and the infection was effectively controlled without sinus tract forming. Overall, all 32 cases received satisfactory efficacy, without influencing subsequent functional reconstruction, and observed infection during the 12-36 months post-operational follow-up. CONCLUSION: The chimeric perforator flap pedicled with the descending branch of the lateral circumflex femoral artery and the lateral thigh muscle flap provides an effective and relative safe procedure for the repair of a large area of deep wound in the foot and ankle, particularly with irregular defect or deep dead space.

Extending the Reach of Craniofacial Free Flaps Using the Descending Branch of the Lateral Circumflex Femoral Vessels.

SUMMARY: Craniofacial free tissue transfer is sometimes complicated by insufficient pedicle length and/or paucity of recipient vessels. A saphenous vein graft can be used to reach the high-flow, large-caliber vessels of the neck, but because of the vein's taper and thick wall, there is often a mismatch. Following the principle of like-for-like, the authors prefer the descending branch of the lateral circumflex femoral vessels to achieve a more anatomical pedicle extension for free tissue transfer in complex craniofacial reconstruction. The authors' experience using the descending branch of the lateral circumflex femoral pedicle extender from 2010 to 2019 was reviewed. Indications, patient characteristics, reconstruction site, flap type, pedicle length, recipient vessels, and vascular complications were noted. The authors reviewed two strategies for implementation of the pedicle extender: in some cases, the flap was first transferred and allowed to perfuse on the descending branch of the lateral circumflex femoral vessels in the thigh, and then transferred to the recipient vessels (double-ischemia transfer); and in other cases, the flap and pedicle extender were transferred such that the flap underwent a single period of ischemia (single-ischemia transfer). The descending branch of the lateral circumflex femoral pedicle extender was used in 17 craniofacial cases. Indications included tumor, trauma, osteoradionecrosis, and congenital. Double-ischemia transfer was used in eight cases and single-ischemia transfer in nine. The longest pedicle extender in the series was 15 cm. Arterial thrombosis occurred in one case. This case series demonstrates that the descending branch of the lateral circumflex femoral pedicle extender is a viable option for complex craniofacial free tissue transfer cases. It provides ample length and excellent vessel match, following the like-for-like principle. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Musculoseptocutaneous Perforator of Anterolateral Thigh Flap: A Clinical Study.

BACKGROUND: The anterolateral thigh flap is one of the most useful workhorse flaps for microsurgical reconstruction. However, it can pose a great challenge to surgeons because of its anatomical variability. As the technology advances, not only septocutaneous or musculocutaneous courses of anterolateral thigh perforators but also a hybrid musculoseptocutaneous perforator pattern have been identified on computerized imaging and on cadaveric study. However, there is a paucity of clinical study in the literature. The aim of this investigation was to identify the features of this pattern. METHODS: All patients undergoing anterolateral thigh flap harvest between September of 2017 and May of 2018 performed by a single surgeon are included. Every pulsatile perforator was dissected to document its location on the thigh, emerging location (septum/muscle), size, course, and origin. RESULTS: Thirty-seven patients with 115 perforators were identified. Ten percent of perforators were septocutaneous, 37 percent were musculoseptocutaneous, and 52 percent were musculocutaneous. Forty-seven percent of perforators emerged on the septum between the rectus femoris and the vastus lateralis. Eighty-one percent of patients had one or more perforators in the "hot zone." Medium and large perforators were more frequently located in the proximal and hot zones. All perforators originated from the vascular tree of the lateral circumflex femoral artery, with 10 percent originating from the transverse branch, 28 percent originating from the oblique branch, and 62 percent originating from the descending branch. CONCLUSIONS: A high proportion of musculoseptocutaneous perforators were identified. The clinical relevance of this is to be very cautious on the skin paddle design while harvesting the flap.

Application of the descending branch of the lateral circumflex femoral artery in coronary artery bypass grafting.

OBJECTIVE: To investigate a technical method for harvesting and using the descending branch of the lateral circumflex femoral artery (DLCFA) in coronary artery bypass grafting (CABG). METHODS: Between January 2017 and January 2019, 40 patients (36 in the planed selection group and 4 in the temporary decision group) with mean age of 49.1 ± 7.5 years received DLCFA as an arterial conduit in CABG. In all patients, the DLCFA was successfully harvested via an anterior thigh incision. Depending on the location of the target vessel, the DLCFA was used as a free graft or a composite graft. RESULTS: Of the 44 patients in the planned selection group, DLCFA harvesting was abandoned in 8 patients because computed tomographic angiography revealed anatomical variation or stenosis of the superficial femoral artery. Of the 5 patients in the temporary decision group, harvesting was abandoned in 1 because of short length and thin caliber. On an average, 3.7 ± 0.9 distal anastomoses were created during CABG, with no adverse effects. The length of the harvested DLCFA was 9.9 ± 1.7 cm, with an average proximal lumen diameter of 3.4 ± 0.7 mm. The DLCFA was used as a free graft in 26 patients and as a "Y"-shape composite graft in 14 patients. Total arterial CABG was performed in 75% of the patients. CONCLUSIONS: The DLCFA is an alternative conduit for CABG. It can be harvested easily and safely. However, preoperative computed tomographic angiography examination is necessary for the smooth application of the DLCFA, and an appropriate strategy for graft establishment should be considered.

Complex Vascular Revascularization in a Young Woman with Type 1 Neurofibromatosis.

We present an uncommon case of a 16-year-old woman with type 1 neurofibromatosis and renovascular hypertension due to bilateral renal stenosis associated with asymptomatic digestive artery stenosis. Our patient was treated by several autologous bypasses to the superior mesenteric artery and the left and right renal arteries. She had no postoperative complications and good clinical and imaging outcomes at 10 years. Furthermore, there are few data on the vascular impairment of this rare disease, thus justifying its presentation.

An anatomical study of the lymph-collecting vessels of the medial thigh and clinical applications of lymphatic vessels preserving profunda femoris artery perforator (LpPAP) flap using pre- and intraoperative indocyanine green (ICG) lymphography.

BACKGROUND AND OBJECTIVES: The profunda femoris artery perforator (PAP) flap is gaining popularity in microsurgical reconstruction. The complications that can occur after the PAP flap harvest include donor-site lymphedema, seroma, or cellulitis. The aim of this study was to evaluate and establish a safer technique for the elevation of lymphatic vessels preserving profunda femoris artery perforator (LpPAP) flap using pre- and intraoperative ICG lymphography. In this article, we also evaluate the anatomical relationship between the PAP flap and lymph-collecting vessels. METHODS: From July of 2018 to January of 2019, 24 patients with soft tissue defects after tumor resection underwent reconstruction using PAP flaps. The lymph-collecting vessels at the medial thigh area were identified using pre- and intraoperative ICG lymphography. A PAP flap was elevated taking care not to damage lymph-collecting vessels. After flap elevation, the anatomical correlation between lymph-collecting vessels and the anterior edge of the gracilis muscle was measured. The postoperative complications were assessed. RESULTS: PAP flaps survived completely in all cases. In all cases, using intraoperative ICG lymphography, surgeons confirmed that the lymph-collecting vessels in the medial thigh region were left intact. There were no donor site complications such as lymphedema, lymphorrhea, or cellulitis. CONCLUSION: The elevation technique of an LpPAP flap is effective in reducing the risk of damage to lymph-collecting vessels, and thus reducing chances of postoperative lymphorrhea or iatrogenic lower limb lymphedema.

Coronary Ostial Patch Angioplasty With Femoral Artery in Takayasu Arteritis.

Takayasu arteritis (TA) occasionally involves the coronary ostium leading to myocardial ischemia. Although surgical coronary ostial angioplasty is desirable for ostial stenosis, the patch materials and long-term results are controversial. We used femoral artery (FA) as a patch material for coronary ostial angioplasty in 3 TA patients. Coronary ostial enlargement with a longitudinal incision followed by rectangular FA patch augmentation was performed to extend the narrowing coronary ostium. In all patients, coronary ostial stenosis was successfully repaired. Ostial angioplasty using an FA patch would be a reasonable surgical strategy to treat coronary ostial stenosis in TA.

Impact of Angiosome Targeted Femorodistal Bypass Surgery on Healing Rate and Outcome in Chronic Limb Threatening Ischaemia.

OBJECTIVE: In the presence of long lesions, in patients with chronic limb threatening ischaemia, a femorodistal bypass is often the only option to avoid major amputation. This study investigated whether targeted bypass to the affected angiosome, according to the angiosome concept definition of direct (DR) and indirect revascularisation (IR), has an impact on wound healing, major amputation rate, and mortality. METHODS: A retrospective analysis was performed at Ghent University Hospital of 201 non-healing ischaemic wounds (Rutherford categories 5 and 6) requiring femorodistal bypass surgery in 177 patients (61% male, median age 69 years) with a follow up of 36 months. For every patient, the site of the ulcer, the type of bypass, and material were identified. Based on ulcer location and distal anastomosis, the legs were divided into DR and IR. Kaplan-Meier univariable analysis was used to estimate cumulative ulcer healing, leg salvage, survival, and patency. RESULTS: DR was performed in 103 legs (51%) and IR in 98 legs (49%), with no difference in comorbidity. The mean wound healing time was seven months. DR did not lead to a higher healing rate. The fastest healing rate was obtained when opting for a DR with an autologous greater saphenous vein (GSV; 90% at 12 months). Cryopreserved allografts also yielded good results, especially for wound healing after IR (85% at 12 months). Major amputation was performed in 28.5% after IR vs. 17.3% after DR (p = .071). There was no difference in mortality rate (36.8% [DR] vs. 41.3% [IR]) (p = .088). Autologous GSV had a longer primary patency, primary assisted patency, and secondary patency (26, 34, and 38 months, respectively) than cryopreserved GSV (12.5, 18, and 24 months, respectively) (p = .002, p = .003, and p = .018, respectively), with no difference between DR and IR. CONCLUSION: Direct or indirect revascularisation performed according to the angiosome concept definition yields similar results with regard to healing rates, limb salvage, and mortality.

Occipital Artery to Middle Cerebral Artery Bypass Using the Descending Branch of the Lateral Circumflex Femoral Artery as an Interposition Graft for Blood Flow Augmentation in Progressive Moyamoya Disease.

BACKGROUND: The superficial temporal artery to middle cerebral artery (MCA) end-to-side anastomosis is the most commonly used direct extracranial-intracranial bypasses type for Moyamoya disease (MMD). In progressive MMD without suitable scalp arteries, other bypass constructs may need to be considered to augment blood flow. CASE DESCRIPTION: We present the exceptional case of a 48-year-old woman with progressive MMD and repeated transient ischemic attacks originating from the right hemisphere despite previous bilateral bypasses. We used the descending branch of the lateral circumflex femoral artery as an interposition graft for an occipital artery to M4 MCA bypass with 2 end-to-side anastomoses to augment blood flow. The ipsilateral occipital artery had already formed bilateral transdural collaterals; the goal was to preserve its supply while using the artery as a donor for an interposition graft. Access to the Sylvian fissure was limited because of the previous superficial temporal artery to MCA bypass with an extensive superficial collateral network necessitating preservation. The posterior aspect of the Sylvian fissure was targeted to revascularize the posterior frontal and parietal region using an interposition graft matching the vessel size of a distal MCA vessel segment. Surgery was technically successful, without complications, and the patient recovered without new neurologic deficits. The bypass graft was patent on postoperative computed tomographic angiography and transcranioplasty ultrasound. CONCLUSIONS: This case illustrates the need for creative bypass constructs in progressive MMD patients with multiple prior surgeries. Two surgical goals are paramount: flow augmentation with preservation of the existing collateral network to avoid complications and new deficits.

Surgery of Renal Artery Aneurysms: A Monocentric Retrospective Study.

BACKGROUND: The aim of the study was to report the results of conventional surgery for renal artery aneurysms (RAAs) in our center. MATERIAL AND METHODS: We retrospectively reviewed the files of all the patients operated for RAAs between 2009 and 2018 in our center. We collected demographic, biological (renal function), morphological (computed tomography [CT] scan), and functional (ultrasound examination and resistance index) preoperative and postoperative data. Clinical and paraclinical operative data were examined. Results were expressed as average ± standard deviation or median and extremes. RESULTS: A total of 26 aneurysms were operated in 20 kidneys (10 right kidneys) among 19 patients, including 13 (68%) women with an average age of 55 (±12) years. Three (16%) patients presented an aneurysm in a single kidney. The discovery of the aneurysm was fortuitous in 14 (74%) patients. One patient with Marfan syndrome was operated after a postpartum rupture. The median diameter of the operated aneurysms was 22 mm (7-48), and 23 (90%) were hilar aneurysms. Arterial repair was carried out in situ in 16 (80%) kidneys. The surgery consisted of a direct arterial repair in 21 cases (81%), including 4 resections and anastomoses, 12 aneurysmorrhaphies, and 5 complex reconstructions. Four arterial replacements were carried out (one prosthetic graft, 2 femoral grafts, and one internal iliac graft). The average duration of renal clamping was 30.5 (±17.3) min. Postoperative renal function was unchanged in all the patients except for one (5.2%) who required 2 days of postoperative dialysis. The resistance index of all the operated kidneys was normal (0.66 ± 0.08) at discharge. Sixteen (70%) of the 23 aneurysms were examined, and anatomopathology concluded them to be of dysplastic origin. At 3 months, a systematic CT scan objectified the patency of 95% of the arterial reconstructions, with 3 stenoses >50%. One stenosis >80% was treated at 7 months by balloon angioplasty. Only one operated kidney presented a loss of viability of its upper pole. The mean duration of follow-up was 54 ± 35 months. By the end of the follow-up, primary and secondary patency rates evaluated by Doppler ultrasound were 90% and 95%, respectively. CONCLUSIONS: Conventional surgery generally performed in situ remains a sure and effective treatment for RAAs. This challenging surgery for a rare disease should be performed in experimented centers.

Superficial Femoral Artery Interposition Graft for Repair of a Ruptured Mycotic Common Carotid Artery Pseudoaneurysm: Case Report and Review of the Literature.

BACKGROUND: Indications for reconstruction of the common carotid artery (CCA) include trauma, iatrogenic injury, neoplastic growth (such as invasive neck carcinomas), postoperative infection, and cervical carotid aneurysm. Although various techniques and conduits have been described, the clinical scenario may preclude the use of the most commonly used grafts. We describe a case using a superficial femoral artery (SFA) interposition graft to repair the CCA and review the available literature, highlighting the feasibility of this technique for carotid artery reconstruction. CASE DESCRIPTION: A patient aged 51 years presented with a ruptured mycotic CCA pseudoaneurysm that developed in the setting of a pharyngeal-carotid fistula. Because of the presence of a pharyngeal-carotid fistula and active infection within the vessel wall, endovascular treatment of the pseudoaneurysm was not feasible, and open surgical correction was required to repair the fistulous connection. Furthermore, owing to the extensive soft tissue infection, the use of a synthetic or venous autograft conduit for repair of the artery was contraindicated. Therefore, we harvested a segment of the SFA and used it as an interposition graft to reconstruct the diseased CCA, achieving an excellent anatomic and clinical result. CONCLUSIONS: This case highlights the feasibility of using an SFA interposition graft for short-segment CCA reconstruction, which can provide significant utility in the setting of a hostile operative field due to prior infection or radiation.

Immediate Lower Extremity Reconstruction Using an Anterolateral Thigh Free Flap With Simultaneous Interposition Graft of Descending Branches of Lateral Circumflex Femoral Vessels.

In a severely injured leg with acute limb ischemia, both immediate revascularization of an endangered part and coverage of soft tissue defect are crucial to limb salvage. In this article, we report a case of an anterolateral thigh free flap with interposition graft of descending branches of the lateral circumflex femoral vessels. A 18-cm-long graft was harvested and used to replace the injured anterior tibial vessels. One month later, a duplex sonogram revealed intact circulation to both the interposition graft and the flap. Despite anatomic inconstancy, the anterolateral thigh free flap is commonly utilized in reconstructive surgeries. When descending branches of the lateral femoral circumflex vessels were included sufficiently, its pedicle can be used to bridge a vascular defect in the extremity while covering soft tissue defect.

Customized reconstruction of complex three-dimensional defects in the extremities with individual design of vastus lateralis muscle-chimeric multi-lobed anterolateral thigh perforator flap.

The anterolateral thigh perforator (ALTP) chimeric flap is one of the most popular procedures for the reconstruction of three-dimensional defects in the extremities. However, the problems of donor-site morbidity and inability to repair very large defects in a one-stage procedure remain. The purpose of this study was to present a novel design of ALTP chimeric flap and its various designs for customized reconstruction of complex three-dimensional defects in the extremities. From January 2009 to June 2017, we retrospectively analyzed 25 patients with complex three-dimensional defects in the extremities. All patients in this series underwent extremity reconstruction using vastus lateralis (VL) muscle-chimeric multi-lobed ALTP flaps, consisting of multi-lobed skin paddles and muscle segment on the same pedicle from the descending branch of the lateral circumflex femoral artery. Three different types of VL muscle-chimeric multi-lobed ALTP flaps were created in this study. The sizes of the multi-lobed skin paddles range from 10 × 6 cm and 9 × 7 cm to 19 × 9 cm and 20 × 9 cm, and the sizes of muscle segments ranged from 9 × 6 cm to 4 × 4 cm. All of the flaps survived. Only one case required re-exploration because of venous congestion. The primary closure of the donor site was successfully achieved in all patients. The mean follow-up time was 14 months. Most of the cases showed satisfactory contour. The VL muscle-chimeric multi-lobed ALTP flap is a reliable option for reconstruction of complex three-dimensional defects of the extremities. It provided flexible design for customized coverage of complex three-dimensional defects with limited donor-site morbidity.

Perforator navigation using color Doppler ultrasound and three-dimensional reconstruction for preoperative planning of optimal lateral circumflex femoral artery system perforator flaps in head and neck reconstruction.

BACKGROUND: The authors introduce an algorithm for preoperative planning of optimal lateral circumflex femoral artery system perforator flap (LCFAPF) supplied by the best quality and the easiest dissection of the perforators and the source vessels for simplified and customized strategies in head and neck reconstruction with perforator navigation using color Doppler ultrasound and three-dimensional reconstruction (3D-CDUS PN). METHODS: Between June 2011 and September 2015, a prospective cohort study was performed with an algorithm based on defect site, perforator type, and pedicle length using 3D-CDUS PN to select optimal perforators arising from the different branches of LCFA in 108 patients. The optimal perforator and flap were determined by perforator caliber and quality, difficulty in flap dissection, and length of the source vessels. Cause and classification of the defect, flap choice, recipient vessels, postoperative course, and complications were analyzed. RESULTS: The source vessels of the perforators were lateral descending branch in 73 cases and oblique branch in 17 cases with ALTPFs, medial descending branch in 12 cases with AMTPFs, and ascending branch in 6 cases with TFLPFs. Straightforward dissection of flaps with septocutaneous (n = 40) and semi-septocutaneous (n = 17) perforators was performed in 52.8% cases. Successful exploration rate and overall flap survival rate were both 100%. Satisfactory functional and esthetic results in both recipient and donor sites with no serious complications were observed in all patients. CONCLUSIONS: Our algorithm using 3D-CDUS PN facilitates selection of optimal flap with better caliber and quality of the perforators and sufficient pedicle length for easy dissection.

Reappraisal of Perforasomes of the Superficial Femoral, Descending Genicular, and Saphenous Arteries and Clinical Applications to Locoregional Reconstruction.

BACKGROUND: The superficial femoral artery and medial thigh region has been an underused donor site for perforator flaps. This study evaluated perforasomes of the superficial femoral artery and its principal branches to review the clinical applications for locoregional reconstruction. METHODS: Twenty-six fresh cadaveric lower extremities were dissected. Perforator size and anatomical course from the superficial femoral artery, descending genicular artery, and saphenous artery branch were documented. Perforators were selectively injected with iodinated contrast to assess vascular territories using computed tomography. A retrospective chart review was conducted on consecutive patients (2014 to 2015). RESULTS: One hundred thirty perforators were mapped in the medial thigh region. Eleven extended medial thigh perforator flaps and 15 hemicircumferential flaps were harvested. The mean distance from the joint line was 16.7 ± 7.3 cm. Perforators arose from the superficial femoral artery (62 percent), saphenous artery branch (23 percent), and descending genicular artery (15 percent). Superficial femoral artery perforators were located around the mid and proximal thigh region (p < 0.001). The median perforasome surface area was 244 cm, representing 36 percent in hemithigh flaps with preferential filling in the anteromedial region. Proximal perforasomes were the smallest. Perforasome areas based on vessel origin were comparable; however, saphenous artery perforators had a broader perforasome compared with descending genicular (p = 0.01) and superficial femoral artery perforators (p = 0.04). Six clinical case examples were presented for knee, thigh, and lower leg reconstruction. CONCLUSIONS: The superficial femoral artery or its branches can provide nontraditional reconstructive perforator flap options in regional reconstruction. They can be simple to harvest using a free-style approach, do not require preoperative imaging, offer a one-stage reconstructive method with low morbidity, and obviate the need for microsurgery or muscle flaps.

Medium- and Large-Sized Autologous Breast Reconstruction using a Fleur-de-lys Profunda Femoris Artery Perforator Flap Design: A Report Comparing Results with the Horizontal Profunda Femoris Artery Perforator Flap.

BACKGROUND: The volume of the profunda femoris artery perforator (PAP) flap limits its indications to small- and medium-sized breast reconstructions after modified radical mastectomy for cancer. We report a modified PAP flap design, including not only a vertical extension that increases its volume but also the skin surface, which suits larger breasts requiring immediate or delayed breast reconstructions and compare the results with our horizontal skin paddle PAP flap experience. PATIENTS AND METHODS: In our center between November 2014 and November 2016, 51 consecutive patients underwent a PAP flap breast reconstruction following breast cancer. A retrospective analysis on the collected data was performed to compare 34 patients with a bra cup smaller than C who underwent 41 horizontal PAP flap procedures, with those (n = 17) of a bra cup greater than or equal to C who underwent 21 fleur-de-lys PAP flap procedures. Demographic, anthropometric, flap and surgical characteristics, postoperative complication rates, and hospital stay were compared between the two groups. RESULTS: The average flap weight was 480 g (range: 340-735 g) for the fleur-de-lys PAP flap group compared with 222 g (range: 187-325 g) for the horizontal PAP flap procedure (p < 0.001). The mean flap dimensions were 25 × 18 cm for the fleur-de-lys PAP flap group compared with 25 × 7 cm in the horizontal PAP flap group. No flap failure was observed in the fleur-de-lys PAP flap group compared with two flap failures secondary to venous thrombosis in the horizontal PAP flap group (NS). Three patients (14%) experienced delayed healing at the donor site compared with four patients (10%) in the horizontal PAP flap group (NS). CONCLUSION: The fleur-de-lys skin paddle design not only allows an increase of the horizontal PAP flap volume, but also increases the skin surface, with an acceptable donor site morbidity. For medium- or large-sized breasts, the fleur-de-lys PAP flap seems to be ideal when a DIEP flap-based reconstruction is contraindicated.
