Modified transmanubrial approach for complicated type 1 cervical rib resection requiring subclavian artery reconstruction.

The transmanubrial musculoskeletal sparing approach (TMA) is commonly used for resecting apical lung tumours with vascular involvement. Non-neoplastic conditions which might require surgical exploration of the thoracic outlet include the 'cervical rib', a clinical condition consisting of an additional rib forming above the first rib and growing from the base of the neck just above the clavicle. Type 1 cervical rib-when a complete cervical rib articulates with the first rib or manubrium of the sternum-is the most challenging scenario where the subclavian artery can be damaged by continuous compression due to the narrow space between clavicle, first rib and supernumerary cervical rib, requiring prosthetic reconstruction of the involved tract. Here, we describe a modified TMA in which the incision in the neck is conducted posteriorly to the sternocleidomastoid muscle, thus allowing safe dissection of the superior and middle trunk of the brachial plexus.

Free-style propeller ulnar artery perforator flaps for radial forearm flap donor site repair.

INTRODUCTION: The radial forearm free flap (RFFF) is still one of the most used free flaps to repair soft tissue defects of the head and neck. Among its main drawbacks, it presents severe donor site complications. We report our experience about the use of free-style propeller ulnar artery perforator flaps (UAP) to repair RFFF donor site. PATIENTS AND METHODS: From February 2010 to June 2020, six patients who underwent immediate tongue reconstruction with RFFF after cancer excision, had the donor site at the forearm reconstructed with a free-style propeller UAP flap. The indication for a UAP flap was based on defect size and the presence of tendons or radial nerve exposure. Ulnar artery perforators were identified intra-operatively with a handheld Doppler. The UAP flaps were harvested and rotated to cover donor site defects. The patients' mean age was 59, ranging from 49 to 65 years old. The defects size ranged from 8-12 cm × 5-7 cm with a mean size of 10.5 × 6.7 cm. RESULTS: The UAP flap harvested ranged from 8-11 cm × 5-7 cm with a mean size of 10.5 × 5.5 cm. The perforators, identified with a power Doppler, were located at the middle third of the forearm. Flaps' rotation varied from 90 to 160° with a mean rotation of 122°. Mean operating time was 60 min ranging from 40 to 75 min for UAP flap elevation. No flap necrosis or tendon exposure occurred. One case of wound dehiscence was reported. Two out of six patients suffered from tendon adhesions to the flap. UAP flap donor site was primarily closed in four out of six patients, whereas two cases required a split-thickness skin grafts. Mean donor site healing time was about 20 days (19.8 days) ranging from 14 to 30 days. Follow-up ranged from 12 to 31 months with a mean follow up time of 19 months (18.6 months). At 6 months follow-up only one patient experienced a functional limitation of wrist and finger joints extension of 20° which required tenolysis. At the end of the patient's follow up that is 22 months, the range of movement was within normal limits. In our casuistry neuropathic pain was absent. CONCLUSIONS: RFF is still a paramount tool in reconstructive surgery but its donor site is still burdened by a high complication rate. Free-style UAP flaps can provide a local and safe solution.

Immediate Soft Tissue Reconstruction in Lower Limb Traumas Using Propeller Perforator Flaps.

BACKGROUND: Open bone fractures represent a demanding clinical condition that can be life- or limb-threatening. For small- to medium-size soft tissue defects of the lower extremity, propeller perforator flaps are a viable option for reconstruction. We report our experience in Gustilo IIIB open fractures treatment with immediate coverage through propeller-based perforator flaps performed in acute setting. METHODS: Between 2019 and 2022, 94 Gustilo III fractures were admitted to our trauma center, and 28 were Gustilo IIIB fractures. Five patients were eligible for an immediate perforator-based propeller flaps reconstruction. The mean age of the patients was 33.8 years. All of them were male. One of them was a heavy smoker (15 cigarettes per day). No other comorbidities were present. RESULTS: The mean operating time, including fracture reduction and fixation time, was 106 minutes. The length of the defect varied between 5 and 7 cm and the width between 3 and 4 cm. We reported no major complications, and none of the patients required a surgical revision of the flap. A patient with smoking habit reported a superficial flap necrosis. The mean follow-up was 5.5 months. No cases of nonunion or osteomyelitis have developed so far. CONCLUSIONS: The use of perforator-based propeller flaps, in acute trauma setting, has not been reported in literature so far. In our experience, propeller perforator flaps are a viable reconstructive option in immediate reconstruction during the acute management of open fractures.

Posterior Circumflex Humeral Artery Perforator Flap: A Cadaveric Study and Case Series.

BACKGROUND: Reconstruction of soft tissue defects of the acromioclavicular region represents a relatively uncommon but challenging event. Many muscular, fasciocutaneous, and perforator flaps have been described, including the posterior circumflex humeral artery perforator (PCHAP) flap based on the direct cutaneous perforator of the PCHA. This study aims to describe a variant of the PCHAP flap, based on a constant musculocutaneous perforator, by means of a cadaveric study and a case series. METHODS: A cadaveric study was conducted using 11 upper limbs. The perforator vessels originating from the PCHA were dissected and the musculocutaneous ones were identified and measured in their length and distance from the deltoid tuberosity. Besides, we retrospectively analyzed the posterior shoulder reconstruction conducted among 2 plastic surgery department (San Gerardo Hospital, Monza and Hospital Papa Giovanni XXIII, Bergamo) using the musculocutaneous perforators of the PCHA. RESULTS: The cadaver dissection showed the presence of a constant musculocutaneous perforator arising from the PCHA. The mean pedicle length is 6.10 ± 1.18 cm, and the musculocutaneous perforator pierces the fascia at a mean distance of 10.4 ± 2.06 cm from the deltoid tuberosity. In all the cadaver dissected, the perforator of interest divided into 2 terminal branches, anterior and posterior, nourishing the skin paddle.In our case series, the mean age of the patients was 66.7 years, the mean size of the defect was 46 cm 2 , the mean operating time was 79.3 minutes, the mean length of hospital stay was 2.7 days, and the complication rate was 28.6%. CONCLUSIONS: According to this preliminary data, the PCHAP flap based on the musculocutaneous perforator seems to be a reliable alternative in posterior shoulder region reconstruction.

Thoracodorsal artery perforator flap, muscle-sparing latissimus dorsi, and descending branch latissimus dorsi: A multicenter retrospective study on early complications and meta-analysis of the literature.

The thoracodorsal (TD) vessels represent a complex vascular system that offers a variety of pedicled and free flaps. Variations of the classical latissimus dorsi (LD) flap have been developed to overcome its major drawbacks. The thoracodorsal artery perforator (TDAP) flap described by Angrigiani represents one of these options. Other techniques have been defined as "muscle-sparing" latissimus dorsi (MSLD) due to the preservation of the LD muscle and the TD nerve, in whole or in part. Nevertheless, the term "muscle sparing" has also been applied to the descending branch LD (DB-LD) flap which requires the denervation of the LD muscle. According to our knowledge, there are no articles in the literature reviewing and comparing the reconstructive options based on the TD vessels. We performed a systematic search in PubMed, Web of Science, and Cochrane databases to perform a literature review and meta-analysis about the reconstructive options based on the TD vessels. The primary outcome of interest was the percentage of flaps developing a specific early complication, i.e., hematoma of the donor site, seroma of the donor site, partial flap loss, total flap loss, wound dehiscence, and wound infection. Moreover, we analyzed the outcomes and complications of our cases, comparing the MSLD flaps, the DB-LD flaps, and the TDAP flaps. According to both our casuistry and the literature, the three techniques can be considered safe in terms of early donor site complications. According to the literature, MSLD has been shown to develop partial flap necrosis more frequently than the TDAP flap.
