Background: The free nipple breast reduction method has certain disadvantages, such as hyposensitivity, loss of lactation, and projection. To eliminate these risks, the authors describe a patient-based technique in which major supplier vessels nipple-areola complex were determined by color Doppler ultrasonography. Pedicles containing designed for reductions. Methods: Sixteen severe gigantomastia patients with mean age 41 years (range, 23 to 60 years) included study. Major perforators 13-...

Cardiovascular problems are a major cause of morbidity and mortality in patients with autosomal dominant polycystic kidney disease (ADPKD). Endothelial dysfunction (ED), which is an early manifestation vascular injury, has been shown ADPKD. Statins have beneficial effect the reversal ED. The aim this study was to investigate effects statin, simvastatin, on ED Sixteen ADPKD having well-preserved renal function were included study. brachial artery evaluated by using high-resolution ultrasound....

Background This study addresses the “pre‐expanded perforator flap concept” by demonstrating a case series of relevant reconstructive procedures and evaluate vessel diameter changes that happen during pre‐expansion procedure. Methods Fourteen patients were treated with 15 flaps. One patient was two pre‐expanded internal mammary artery In other cases, thoracodorsal, circumflex scapular, lumbar, intercostal, lateral femoral, deep inferior epigastric flaps used. Technical details rate...

Although some algorithms are defined for the treatment of advanced hepatocellular carcinoma (HCC), expected survival cannot be prolonged as it is intended. Treatment options this group patients limited. Radioembolization with yttrium-90 (Y-90) microspheres a new modality, which has also been used in HCC patients. In study, authors aimed to assess efficiency radioembolization Y-90 and evaluate prognostic factors that influence patients.The retrospectively evaluated data 29 who had resin or...

Foreign body ingestion is a common problem in children, but it also seen among adults. Most foreign bodies pass through the gastrointestinal tract without causing complications. Perforation of gut by body, followed migration to liver quite rare. Herein we report case inadvertent sewing needle that perforated duodenum and migrated liver. The patient was monitored weekly with abdominal radiographs, displacement could not be observed. At follow-up, right upper quadrant pain noted. Two weeks...

We report a case of pseudoaneurysm the medial circumflex femoral artery that presented 4 months following cementless left total hip arthroplasty (THA). A successful embolization was achieved using super-selective catheterization and coil embolization. Arterial complications associated with THA are remarkably rare. Endovascular techniques have been shown to be effective considered valid alternative conventional surgery.

The popularity of the fibular free flap in mandibular reconstructions is persisting, and major donor area complications rarely occur after operations. Still, we have observed a pseudo–compartment syndrome 52-year-old patient on 12th postoperative day reconstruction with flap.

Focal nodular hyperplasia (FNH) and hemangioma are benign generally asymptomatic hepatic tumors. With distinctive imaging findings on dynamic computed tomography (CT) magnetic resonance (MRI), differentiation of these tumors from metastases can be made. We described lesions in a 57-year-old man who presented with rectal adenocarcinoma for staging.
