Reliability and Safety of Cross-Leg Free Latissmus Dorsi Muscle Flap in Reconstruction of Mutilating Leg Injuries Using End-to-Side Anastomosis.

 Free tissue transfer is considered the gold standard option for the reconstruction of distal leg defects. Free tissue transfer using recipient vessels in the contralateral leg (cross-leg bridge) is a potential option to supply the flap if there are no suitable recipient vessels in the injured leg. Most studies have described this technique using end-to-end anastomosis which sacrifices the main vessel in the uninjured leg.

The role of the surgical resection distance from the pylorus after laparoscopic sleeve gastrectomy: a prospective cohort study from an academic medical center in Egypt.

Background: Laparoscopic sleeve gastrectomy was recently described as an effective approach for the operative treatment of obesity, but the ideal procedure remains controversial. One of the most debated issues is the resection distance from the pylorus. We conducted this study to elucidate any potential differences in the short-term outcomes between 2 and 6 cm distance from the pylorus in laparoscopic sleeve gastrectomy.

The Effect of Type of Femoral Component Fixation on Mortality and Morbidity after Hip Hemiarthroplasty: A Systematic Review and Meta-Analysis.

Background: Hip hemiarthroplasty is a well-established treatment of displaced femoral neck fracture, although debate exists over whether cemented or uncemented fixation is superior. Uncemented prostheses have typically been used in younger, healthier patients and cemented prostheses in older patients with less-stable bone. Also, earlier research has suggested that bone cement has cytotoxic effects and may trigger cardiovascular and respiratory adverse events.

Perforator-Pedicled Propeller Flaps for Lower Extremity Reconstruction.

Reconstruction of the lower extremity is considered a major challenge due to frequent bone exposure and the absence of local tissue redundancy, as well as often due to the presence of vascular insufficiency. Many surgeons have preferred free flaps especially for reconstructing the more distal lower limb defects until the evolution of pedicled perforator flaps and propeller flaps in particular provided a like-with-like reconstruction of the lower extremity without affecting the main vessels of the limb or the underlying muscles, and without the risk of any microanastomosis especially in patients with multiple comorbidities. Perforator-pedicled propeller flaps as local flaps in the lower extremity are best suited for small- and medium-sized defects with minimal donor-site morbidity, regardless of the cause of the defect.

Early return of reflected waves increases right ventricular wall stress in chronic thromboembolic pulmonary hypertension.

Pulmonary vascular resistance (PVR) and compliance are comparable in proximal and distal chronic thromboembolic pulmonary hypertension (CTEPH). However, proximal CTEPH is associated with inferior right ventricular (RV) adaptation. Early wave reflection in proximal CTEPH may be responsible for altered RV function.
