Summary: High-energy lower limb trauma may result in complex defects with extensive vascular damage. Free flap reconstruction in these cases may require vein grafts to reach healthy proximal recipient vessels. Vascular loops are an increasingly popular technique in managing recipient vessels in reconstructive microsurgery, especially in the lower limb. The use of an entire omega segment of the greater saphenous vein had not been described before but offered two advantages: the caliber match for arterial repair was better using one of the limbs of the omega compared with the parent greater saphenous vein, and it allowed two venous anastomoses instead of one. A case report of a fully bifurcated segment of the greater saphenous vein as a vascular loop for microvascular reconstruction in the lower limb is presented. To the best of the authors’ knowledge, no similar case has been reported previously.

Background. Our study aims to evaluate the results of platelet-rich plasma (PRP) infiltration after arthroscopic repair of the rotator cuff. Methods. We carried out a randomized simple blind clinical trial with an initial sample of 38 patients. Of those, three were excluded intraoperatively. These patients were assigned into two groups: rotator cuff suture with PRP administration (n = 17) and rotator cuff suture without PRP administration (n = 18). Intraoperatively, we excluded all massive tears, i.e., those with more than 3 cm retraction or affecting more than two tendons, Snyder type C4 or Patte grade III. We performed clinical and radiological evaluations at the 2 nd and 6 th week, 3 rd and 6 th month, and the last assessment at the 1 st year. Results. We did not demonstrate statistically significant differences comparing measurements, clinical scales applied (AVS scale, DASH, Constant-Murley, Shoulder test, UCLA test, and shoulder range of motion) during the follow-up period, and radiological findings between both groups. Conclusions. Several research studies have shown PRP efficacy in injured tendons and ligaments. Some of them have even obtained satisfactory clinical results applied in rotator cuff repair, whereas others, including ours, have not shown statistically significant clinical improvement.

Summary: In existing literature about elastofibroma dorsi (ED), no cases reported ED arising after latissimus dorsi flap harvest. Concretely, we present a patient who developed an ED at latissimus dorsi free flap donor site 10 years after harvesting. After our research, we found the occurrence of ED after thoracotomy surgery, stressing the importance of previous local trauma. Latissimus dorsi flap harvest is also a local traumatic episode, although its association with ED has not been previously reported. Thus, ED should be considered in the differential diagnosis of deep soft tissue lumps after latissimus dorsi harvest.
