Virtual ABI: A computationally derived ABI index for noninvasive assessment of femoro-popliteal bypass surgery outcome.

Background And Objective: Peripheral arterial disease of the lower limbs, which affects 12-14% of the population, is often treated by bypassing a blocked portion of the vessel. Due to the limited ability of clinicians to predict the outcome of a selected bypass strategy, the five-year graft occlusion ranges from 50% to 90%, with a 20% risk of amputation in the first 5 years after the surgery. The aim of this study was to develop a computational procedure that could enable surgeons to reduce negative effects by assessing patient-specific response to the available surgical strategies.

Transplanted Kidney Increases Nitric Oxide Formation With Metabolic Acidosis Reduction.

Objectives: As a vasodilator, nitric oxide is considered to play a significant role in the homeostatic regulation of renal hemodynamics. To test the hypothesis that a kidney graft is capable of producing nitric oxide immediately after renal transplant surgery, we examined the possibility that it positively affects local metabolic acidosis.

Materials And Methods: In kidney transplant recipients, we analyzed renal vein and central vein blood samples, which reflect local and systemic metabolic alterations, respectively.

Healthcare associated infection in adult surgical and medical patients hospitalized in tertiary hospital in Belgrade, Serbia: a seven years prospective cohort study.

: () infection (CDI) is one of the most common healthcare-associated (HA) infections in contemporary medicine. The risk factors (RFs) for HA CDI in medical and surgical patients are poorly investigated in countries with a limited resource healthcare system. Therefore, the aim of the study was to investigate differences in patients' characteristics, factors related to healthcare and outcomes associated with HA CDI in surgical and medical patients in tertiary healthcare centre in Serbia.

Introduction: Q fever is a zoonosis which commonly manifests as an acute febrile disease accompanied by pneumonia or hepatitis. The aim of this study was to reveal the reservoirs, sources and routes of infection relevant for the Q fever outbreak that occurred in the border region between Serbia and Montenegro.

Methodology: A prospective study was conducted from 3rd to 23rd March, 2016 in Brodarevo, village near the Serbian-Montenegro border.

Aortobifemoral reconstruction and renal transplantation in a patient with abdominal aortic aneurysm and occlusion of iliac arteries: A case report.

Introduction: Aortoiliac occlusive disease and abdominal aortic aneurysm in patients with renal insufficiency on hemodialysis can significantly influence the success of renal transplantation. In the recent past, advanced atherosclerosis was considered as contraindication for renal transplantation. Complicated creation of vascular anastomoses and progression of occlusive or aneurysmal disease were the main reasons.

Endovascular treatment of the subclavian artery aneurysm in high-risk patient - a single-center experience.

We present our first experience with endovascular treatment of 6 subclavian artery aneurysms (SAA) occurring in five male and one female patient. All patients, in our studies, according to ASA classification were high risk for open repair of SAA. The etiology of the all aneurysms was atherosclerosis degeneration of the artery.

Influence of open surgical and endovascular abdominal aortic aneurysm repair on clot quality assessed by ROTEM® test.

Introduction/aim: The disturbances in hemostasis are often in open surgical repair (OR) and endovascular repair (EVAR) of an abdominal aortic aneurysm (AAA). These changes may influence the perioperative and early postoperative period inducing serious complications. The aim of this study was to compare the impact of OR and EVAR of AAA on clot quality assessed by rotational thromboelastometry (ROTEM®) tests.

Different techniques of vessel reconstruction during kidney transplantation.

Background/aim: Multiple renal arteries (MRAs) represent a surgical challenge by the difficulty in performing anastomoses, bleeding and stenosis. MRAs should be preserved and special attention should be paid to accessory polar arteries. All renal arteries (RAs) must be reconstructed and prepared for safe anastomosis.

Specificities of transplantation of kidneys procured from donors with situs inversus totalis--a case report and review of the literature.

Introduction: Situs inversus totalis (SIT) represents a total vertical transposition of the thoracic and abdominal organs which are arranged in a mirror image reversal of the normal positioning. We presented a successful pre-dialysis kidney transplantation from a living sibling donor with SIT and the longest donor follow-up period, along with analysis of the reviewed literature.

Case Report: The pair for pre-dialysis kidney transplantation included a 68-year-old mother and 34-year-old daughter at low immunological risk.

Renal transplantation promptly restores excretory function but disturbed L-arginine metabolism persists in patients during the early period after surgery.

The synthesis and whole body metabolism of L-arginine (Arg) are disturbed in renal diseases. Renal transplantation represents the best therapy in the end-stage of these diseases. In the present we compared alterations of plasma Arg and related compounds with renal excretory function in patients with end-stage renal disease, before and after kidney transplantation.

Visceral hybrid reconstruction of thoracoabdominal aortic aneurysm after open repair of type A aortic dissection by the Bentall procedure with the elephant trunk technique--a case report.

Introduction: Reconstruction of chronic type B dissection and thoracoabdominal aortic aneurysm (TAAA) remaining after the emergency reconstruction of the ascending thoracic aorta and aortic arch for acute type A dissection represents one of the major surgical challenges. Complications of chronic type B dissection are aneurysmal formation and rupture of an aortic aneurysm with a high mortality rate. We presented a case of visceral hybrid reconstruction of TAAA secondary to chronic dissection type B after the Bentall procedure with the 'elephant trunk' technique due to acute type A aortic dissection in a high-risk patient.

Endovascular repair of ruptured abdominal aortic aneurysm.

Introduction: Rupture of an abdominal aortic aneurysm (AAA) is a potentially lethal state. Only half of patients with ruptured AAA reach the hospital alive. The alternative for open reconstruction of this condition is endovascular repair (EVAR).

Conversion from calcineurin inhibitors to sirolimus of recipients with chronic kidney graft disease grade III for a period 2003-2011.

Background/aim: Tremendous breakthrough in solid organ transplantation was made with the introduction of calcineurin inhibitors (CNI). At the same time, they are potentially nephrotoxic drugs with influence on onset and progression of renal graft failure. The aim of this study was to evaluate the outcome of a conversion from CNI-based immunosuppressive protocol to sirolimus (SRL) in recipients with graft in chronic kidney disease (CKD) grade III and proteinuria below 500 mg/day.

Comparison of analgesic effect of intrathecal morphine alone or in combination with bupivacaine and fentanyl in patients undergoing total gastrectomy: a prospective randomized, double blind clinical trial.

Background/aim: Combined spinal-epidural-general anesthesia has several advantages over general anesthesia alone. This study was designed to compare the efficacy of intrathecal (IT) morphine alone, or in combination with bupivacaine and fentanyl, as part of a combined spinal-epidural (CSE) analgesia, in patients undergoing elective total gastrectomy.

Methods: This prospective, randomized double-blind study included 60 patients undergoing total gastrectomy under general anesthesia and CSE.

Ambulatory phlebectomy under tumescent local anesthesia in a kidney-transplant patient.

Introduction: Tumescent local anesthesia (TLA) is widely used for ambulatory surgery. Patients with transplanted or gans are on immunosuppressive therapy and with risk for organ rejection or severe infection.

Case Report: Saphe nectomy with phlebectomy on the left leg under TLA was performed in a patient with kidney transplantation per formed four years ago.

Unilateral nephrectomy causes an early abrupt decrease in plasma arginine and simultaneous reduction in glomerular filtration rate in living kidney donors.

Objectives: Living donor kidney transplantation is regarded as beneficial to allograft recipients and not particularly detrimental to the donors. Recently we have documented a reduced glomerular filtration rate (GFR) in living kidney donors (LKDs). Considering kidneys as essential for l-arginine (Arg) metabolism, in the present study we analyzed plasma Arg and related compounds comparing them with the function of remaining kidney in LKDs after donation.

Endovascular repair of mycotic aneurysm of the descending thoracic aorta: diagnostic and therapeutic dilemmas-two case reports with 1-year follow-up.

A mycotic aneurysm of the thoracic aorta is a rare diagnosis with high mortality. We present two cases of endovascular reconstruction of mycotic descending thoracic aorta. Specific or nonspecific bacterial or other infectious agent in serial samples of blood, urine, cerebrospinal fluid, and pleural puncture was not detected in the first case, but we found in sputum sample Mycobacterium tuberculosis in the second patient.

[Elective visceral hybrid repair of type III thoracoabdominal aortic aneurysm].

Introduction: According to the classification given by Crawford et al. type III thoracoabdominal aortic aneurysm (TAAA) is dilatation of the aorta from the level of the rib 6 to the separation of the aorta below the renal arteries, capturing all the visceral branch of aorta. Visceral hybrid reconstruction of TAAA is a procedure developed in recent years in the world, which involves a combination of conventional, open and endovascular aortic reconstruction surgery at the level of separation of the left subclavian artery to the level of visceral branches of aorta.

[Subcutaneous paratibial fasciotomy in the treatment of chronic venous ulcer].

Background/aim: Chronic venous ulcer (CVU), a disease of high incidence, is one of the most serious chronic venous insufficiency complications. It has been estimated that there are 1%-2% of adults with CVU deriving a high social significance. The aim of this study was to, using the clinical experience, determine the influence of subcutaneous paratibial fasciotomy (SPF) on the course and the treatment outcome of CVU.

Living unrelated donor kidney transplantation--a fourteen-year experience.

Background: In countries without a national organization for retrieval and distribution of organs of the deceased donors, problem of organ shortage is still not resolved. In order to increase the number of kidney transplantations we started with the program of living unrelated - spousal donors. The aim of this study was to compare treatment outcome and renal graft function in patients receiving the graft from spousal and those receiving ghe graft from living related donors.

Recidive of renal cell carcinoma tumor thrombus in inferior vena cava via lumbar vein.

Renal cell carcinoma (RCC) develops tumor thrombus in the renal vein and inferior vena cava (IVC) in 10% of cases. Surgical treatment is radical nephrectomy and thrombectomy of the IVC. Local recidive can develop in the lumbar fossa, lymph nodes, and the IVC.

Changes of glomerular filtration after nephrectomy in living donor.

A possible complication after donor nephrectomy is a decrease in glomerular filtration rate. The goal of our investigation is to estimate the function of the remaining donor kidney in the first 6 months after nephrectomy using the equations Cockcroft-Gault, Modification of Diet in Renal Disease 1 (MDRD1) and MDRD2. In addition to basic age and sex data, we collected standard biochemical data from blood: creatinine, blood urea nitrogen, and albumin.
