Retroperitoneal tumour resection in fifteen consecutive cases: Single centre experience.

Introduction: Retroperitoneal tumours (RTs) in adults are a rare heterogeneous group of neoplasms arising from the retroperitoneal space. RTs'clinical manifestations are nonspecific and depend on their anatomical positioning and relation with bordering structures. Our study aimed to retrospectively evaluate our patients' diagnosis, length of hospital stay, disease-free period and postoperative metastasis occurrence.

Fresh arterial allograft as a replacement for an infected common femoral prosthetic graft and recurrent false aneurysm.

Replacing an infected vascular prosthetic conduit with an allograft is a possible solution of this complication given the low recurrence of infection. It is most commonly utilized for cases where the use of autologous tissue is not an option. We present the case of a 70-year-old patient who had undergone repeated vascular reconstructions in the right lower limb.

Early Uterine Transplant Graft Loss Due to Thrombosis: Single-Center Experience With Causes, Prevention, Diagnosis, and Treatment.

Uterus transplantation (UTx) is a promising treatment option for women who wish to give birth but suffer from absolute uterine factor infertility. This paper presents an interim analysis of a trial focusing on the causes, prevention, diagnosis, and management of graft thrombosis. Our team analyzed 10 cases of UTx (recipients numbered 1 to 10).

Cholesterol efflux and macrophage polarization in human adipose tissue.

The pro-inflammatory status of adipose tissue (AT) has been found to be related to reverse cholesterol transport (RCT) from peritoneal macrophages. However, this finding was made in experimental models using induced peritonitis and isolated peritoneal macrophages of animals. This experimental relationship is in agreement with RCT changes in man in two extreme situations, sepsis or cardiovascular complications.

Giant aggressive intra-abdominal desmoid-type fibromatosis - case report.

Introduction: Aggressive fibromatosis, also known as desmoid tumour (DT), is a locally invasive soft tissue malignancy originating from fascial planes, connective tissue, and musculoaponeurotic structures of the muscles. The symptoms greatly depend on the location and size of the tumour.

Case Report: A 68-year-old male patient without any comorbidities with a large, palpable mass in the abdomen underwent computed tomography (CT) of the abdomen during diagnostic examination in September 2017 in another centre.

Biliary obstruction following transjugular intrahepatic portosystemic shunt placement in a patient after liver transplantation: A case report.

Background: Transjugular intrahepatic portosystemic shunt (TIPS) is a method used to decrease portal hypertension. Biliary stricture is the rarest of the complications associated with this procedure with only 12 cases previously reported in the literature. None of these cases have documented the resolution of biliary stenosis induced by a stent graft.

Thrombolysis as a treatment for transplant renal artery thrombosis - a report of three unsuccessful cases and an overview of reported cases.

Introduction: Thrombolysis has been suggested as a feasible method to treat arterial renal transplant thrombosis under conditions of short duration of ischemia. Data on maximal duration of ischemia that are still feasible to treat are scarce.

Methods: We retrospectively analysed our experience involving three attempts to utilize thrombolysis to treat transplant renal artery thrombosis.

Cell Viability Assessment Using Fluorescence Vital Dyes and Confocal Microscopy in Evaluating Freezing and Thawing Protocols Used in Cryopreservation of Allogeneic Venous Grafts.

The authors present their contribution to the improvement of methods suitable for the detection of the freezing and thawing damage of cells of cryopreserved venous grafts used for lower limb revascularization procedures. They studied the post-thaw viability of cells of the wall of cryopreserved venous grafts (CVG) immediately after thawing and after 24 and 48 h culture at +37 °C in two groups of six CVG selected randomly for slow thawing in the refrigerator and rapid thawing in a water bath at +37 °C. The grafts were collected from multi-organ and tissue brain-dead donors, cryopreserved, and stored in a liquid nitrogen vapor phase for five years.
