Single-Stage Immediate Breast Reconstruction with Acellular Dermal Matrix after Breast Cancer: Comparative Study and Evaluation of Breast Reconstruction Outcomes.

We evaluate postoperative complications, aesthetic results and satisfaction outcomes in patients with breast cancer after intervening with a skin-sparing or nipple-sparing mastectomy with an immediate prosthetic reconstruction with or without a biological mesh. Patients with multifocal breast cancer, ductal carcinoma in situ with an indication for a mastectomy and cT2 tumors with no response to primary systemic treatment were included, whereas patients aged >75 years, with inflammatory carcinoma, and severe circulatory disorders were excluded. Patients in the control group were reconstructed using a prosthesis, whereas the study group included patients reconstructed using a prosthesis and biological acellular porcine dermal mesh (Strattice™). In both groups, the result was assessed using the BREAST-Q instrument. A total of 51 patients (62 intervened breasts) were included in the study group and 38 patients (41 intervened breasts) in the control group. Implant loss and removal occurred in three patients in the study group (5.9%) and nine patients in the control group (24.3%; p = 0.030). Infections appeared in three patients in the study group (4.8%) and three patients in the control group (7.3%; p = 1.00). Skin necrosis appeared in 5 patients in the study group (12.2%) and 11 patients in the control group (21.6%; p = 0.367). Seroma appeared in five patients in the study group (12.2%) and five patients in the control group (8.1%; p = 0.514). The BREAST-Q questionnaire is a comparison between both groups regarding "satisfaction with breasts after surgery" (p = 0.026), "sexual well-being after intervention" (p = 0.010) and "satisfaction with the information received" (p = 0.049). We have noted a statistically significant decrease in implant loss in women receiving an implant with a biological mesh. A higher satisfaction was observed in patients reconstructed using Strattice™, with statistically significant differences in three items.

Barber Pole Sign in CT Angiography, Adult Presentation of Midgut Malrotation: A Case Report.

Adult midgut volvulus is a challenging diagnosis because of its low incidence and nonspecific symptoms. Diagnostic delay and long-term complaints are frequent in this clinical scenario. We reported a patient referred to our diagnostic imaging unit with intermittent abdominal pain, bloating and episodic vomiting for several years. He underwent barium gastrointestinal transit and abdominal ultrasound, which revealed severe gastric dilatation, food retention and slow transit until a depressed duodenojejunal flexure, with malrotation of the midgut and jejunal loops being located in the right upper quadrant. Computed tomography angiography was performed, showing rotation of the small intestine around the mesentery root, suggestive of midgut malrotation. In addition, an abnormal twisted disposition of superior mesenteric artery with corkscrew appearance was seen, shaping the pole-barber sign which was evident in volume rendering three-dimensional reconstructions. The patient underwent scheduled surgical treatment without any complication and had good outcome after hospital discharge and follow-up. Computed tomography plays an important role in evaluation of adult midgut volvulus. In addition, angiographic reconstructions can help us to assess the anatomic disposition of mesenteric vascular supply. Both of these assessments are useful in preoperative management.

Resolution of left ventricular thrombus by rivaroxaban.

Intracardiac thrombus is a potentially life-threatening condition, with a high risk of embolic complications. Although vitamin K antagonists have been traditionally used for the treatment of intracardiac thrombus, they have relevant disadvantages that limit their use. Rivaroxaban is a once daily oral anticoagulant, currently indicated for the prevention of stroke and systemic embolism in patients with nonvalvular atrial fibrillation, and for the prevention and treatment of venous thromboembolism. We present the case of a 78-year-old man with nonvalvular atrial fibrillation, heart failure and creatinine clearance of 40 ml/min, anticoagulated with rivaroxaban 15 mg/day as the patient had very difficult access to hematologic controls. The transthoracic echocardiogram showed dilated left ventricle, severe left ventricular dysfunction and two images of thrombus, which disappeared after 4 weeks of treatment with rivaroxaban. To our knowledge, this is the first case reported regarding the resolution of left ventricular thrombosis with rivaroxaban.
