RESUMEN
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. He was admitted to our department due to a progressively growing mass in the right groin and subsequently placed on the waiting list for a fresh allograft. The patient had the infected false aneurysm and prosthetic material of the femoral bifurcation replaced with an arterial allograft. The previous femoral popliteal autovenous bypass graft was reimplanted into the allograft. There were signs of sepsis during the operation; however, the blood culture was negative. Cultures from neither the wound nor the drain revealed the presence of any bacteria. The patient was discharged on the seventh post-operative day with prophylactic antibiotics. An early followup confirmed that there were no signs of recurrent infection and that the reconstruction remained patent. Seven and half months after the surgery, the femoral popliteal bypass graft became occluded and a conservative approach was chosen. A small thrombosed false aneurysm of the graft was revealed two years after the surgery due to transient non-compliance of the patient to immunosuppression therapy. It was treated conservatively. Two and a half years after the surgery, the allograft still remains open and the limb is preserved.

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. METHODS: From 2011 to 2019, fifteen suspected RT resections were performed at our centre. Retrospective analysis of patients' hospital stays, follow-up, histological and immunological tumour profile, and metastasis occurrence/ re-occurrence was performed. RESULT: All of the 15 (100%) patients were males. The average age of our patients was 44 years (SD ± 11.2 years), average hospital stay was 7.4 days (SD±3.4 days) (Tab.1). All resected tumours underwent histological and immunological evaluation. Based on histological examination of the resected tumours, nonseminomatous germ cell tumours were present in 12 (80%) patients - including teratoma in 4 (26.6%) patients, seminoma in 2 (13.3%) patients, and malignant B-cell lymphoma in 1 (6.6%) patient. The average patient follow-up was 42.7 months (SD±31.4.9 months). Complete remission after the surgery was achieved in 11 (76.9%) patients, and 2 (13.3%) patients were lost in follow-up. CONCLUSION: RT is a rare heterogeneous group of neoplasm. The patient's prognosis dramatically depends on the type of tumour, metastasis occurrence and re-occurrence, and the surgeons' ability to resect the tumour completely.

INTRODUCTION: This case report describes surgical treatment of chronic mesenteric ischemia in a polymorbid patient with the history of an aorto-bifemoral bypass implant. CASE REPORT: The patient suffered from chronic occlusions of the mesenteric arteries. He experienced postprandial pain and significant weight loss. Endovascular repair of the occlusions failed. Open single retrograde bypass from the left branch of the aorto-bifemoral graft to the superior mesenteric artery was implanted successfully. CONCLUSION: The discussion briefly mentions current trends in the treatment of chronic mesenteric ischemia. Despite the development of interventional radiology, surgical treatment remains a relevant alternative for the management of chronic mesenteric ischemia.

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. The CT scan revealed a giant intraperitoneal 30×40cm tumour without signs of infiltrating the surrounding organs and large vessels. The tumour biopsy revealed an aggressive DT. The patient was scheduled for tumour resection. Midline laparotomy was performed in the supine position under general anaesthesia. After gaining access to the abdominal cavity, 8 litres of clear ascites were evacuated. The tumour was not attached to the abdominal wall. Large omentum was freed from the DT. The perioperative finding confirmed the CT images of DT encapsulation of the medial colic artery, part of the small intestine, and transverse colon. The tumour was resected with part of the mesenteric radix, 30 cm of small intestine, and 2/3 of the transverse colon. After the DT was removed entirely, the small intestine was re-anastomosed end to end. The abdominal cavity and the liver were carefully checked for bleeding. The abdominal cavity was closed in a standard manner. RESULTS: The postoperative hospital stay was uneventful. The patient was discharged on the 7th postoperative day with prophylactic low weight molecular heparin for one month. Currently, we have five months of follow-up with no signs of DT recurrence based on CT examination. The histology of the resected tumour confirmed the diagnosis of a desmoid tumour (aggressive abdominal fibromatosis). CONCLUSION: Desmoid tumours are benign neoplasms with no metastatic potential. However, their treatment is challenging due to their aggressive growth, infiltrative behaviour, and a high tendency to recur.

OBJECTIVES: The aim of this study was to investigate the association of lower urinary tract dysfunctions with urinary leakage from ureterocystoneoanastomosis (UCNA) after kidney transplantation. BACKGROUND: The UCNA leakage after kidney transplantation can be associated with various conditions while severe lower urinary tract dysfunctions could be one of them. METHODS: The analysis included all men who underwent kidney transplantation between January 2009 and December 2014. The parameters of storage and voiding functions were evaluated. All patients were monitored during their post-transplantation period for the incidence of urinary leakage from UCNA. Urodynamic parameters were compared between men with and without a documented leakage. RESULTS: The study cohort included 127 male patients, while UCNA leakage was observed in 11 (8.7 %) patients. Significant differences between both groups of patients were found for storage parameters (patients with leakage had smaller volume at first and a normal desire to void, smaller maximal cystometric capacity, and lower detrusor compliance) and voiding parameters (patients with leakage had a lower maximal flow rate, higher detrusor pressure at maximal flow rate and higher bladder outlet obstruction index). CONCLUSION: This study shows an association between lower urinary tract dysfunction and UCNA leakage in men without previous urological history (Tab. 2, Fig. 2, Ref. 24).

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. We searched through literature on PubMed and compared the data we found with our own experience. RESULTS: In case number 1 of our cohort, thrombolysis was initiated 12 hours after the onset of thrombosis and had to be ceased after five hours due to the formation of a haematoma. Perfusion of the graft was restored but it did not regain function, most likely due to long ischemia time. In case number 2, an attempt to use thrombolysis was unsuccessful due to failure to cross the graft artery occlusion with a guidewire. Thrombosis was most likely caused by chronic rejection of the graft. In case number 3, thrombolysis restored arterial patency but, due to an onset of ischemia, which lasted 2 to 3 days, did not lead to restoration of graft function. The prolonged ischemia period in case three occurred, at least in part, due to failure to perform an ultrasound scan when the patient was first admitted. CONCLUSION: We can confirm that thrombolysis for transplant renal artery thrombosis seems to be feasible only when the condition has a short duration. In the event of sudden deterioration of graft function, the absence of perfusion must always be ruled out by ultrasound scan.

INTRODUCTION: Liver transplantation is established as a lifesaving procedure for patients with acute and chronic liver failure, as well as certain selected malignancies. Due to a continuing organ shortage and ever-growing patient waiting lists, donation after cardiac death (DCD) is becoming more frequently utilized in order to close the gap between “supply and demand”. METHODS: A retrospective analysis of DCD and subsequent liver transplantations was performed. RESULTS: From May 2016 to September 2019, a total of 9 DCD liver transplantations were performed in our institution. All cases except one were primary liver transplantations. The recipients comprised 5 (56%) males and 4 (44%) females. The mean DCD donor age was 41±12 (22-57) years, with ventilation duration of 7±1 days and warm ischemia time 19±3 minutes. The average recipient age was 51±22 (4-73) years, with an average cold ischemia 3h:59m±27m and manipulation time of 23±5 minutes. Periprocedural mortality was 1 (11%). Hepatitis C recurrence was documented in 1 (11%) patient. The mean follow-up time was 19±13 (7-37) months. Until now, we have not observed any signs of ischemic cholangiopathy. CONCLUSION: DCD liver transplantation allows us to enlarge the pool of potential liver grafts, thus decreasing the time spent on the liver recipient waiting list. This paper documents the first series of DCD liver transplantations in the Czech Republic.

Thanks to an increased number of living-donor kidney transplants the IKEM transplant program offers the possibility of obtaining adipose tissue for scientific purposes from patients with varying degrees of atherosclerosis. Surgery mainly addresses vascular complications of this disease. On the other hand, surgery may also be the reason for the development and acceleration of atherosclerosis - for instance, acceleration of atherosclerosis in the living kidney donor, particularly if, although meeting internationally recognized donation criteria, the donor actually suffers from metabolic syndrome. The effort to refine the examinations of living kidney donors in terms of eliminating the risk of developing atherosclerosis is a long-term project. The aims are to determine the risk factors for living kidney donors and to prevent long-term complications after donation. The paper gives a detailed description of the technique of adipose tissue collection from a living kidney donor and of the experimental model for the research of atherosclerosis.The project has the potential to increase the safety of living kidney donation and to enhance our present knowledge of atherosclerosis development mechanisms.

INTRODUCTION: Aorto-iliac occlusive disease is best treated with endovascular angioplasty/stenting or surgical bypass, depending on disease severity. Aorto-iliac endarterectomy was frequently used until the 1980s. However, it can still be performed in cases of previous failure or contraindication of standard methods. The aim was a retrospective evaluation of a single-center case series of aorto-iliac endarterectomy. METHODS: Seven patients at mean age 60±8 years (5768 years) were treated by aorto-iliac endarterectomy between 2013 and 2018. Rutherford categories of leg ischemia were 2 (moderate claudication) 3x, 3 (severe claudication) 2x, 4 (rest pain) and 5 (toe gangrene). The reasons for endarterectomy approach were: late in-stent iliac occlusion in an oncology patient, failure or complication of previous endovascular treatment of short iliac stenosis 2×, high infection risk of prosthesis use in long iliac-femoral occlusion, and short iliac occlusions 3x. Two patients after previous organ transplant were on immunosuppression. RESULTS: Technical success rate was 100%. There was no peri-operative (30 days) death or amputation. Mean follow-up was 17 months (1.1 month3.3 year). One patient required additional tibial bypass 1 month after endarterectomy to heal foot gangrene. One patient developed symptomatic re-stenosis which was treated with iliac stenting 8 months after procedure. All patients clinically improved and recovered from leg ischemia. Two patients died of tumor with preserved limb 1.1 month and 3.1 years after procedure, respectively. Five remaining patients are asymptomatic with patent revascularization to date. CONCLUSION: Aorto-iliac endarterectomy is a vital alternative technique for revascularization in selected patients when other methods seem inappropriate. Key words: endarterectomy - peripheral arterial disease - iliac artery - abdominal aorta.

INTRODUCTION: Uterus transplantation is the youngest solid organ transplantation described in the literature. This procedure is the only treatment method for congenital or acquired Absolute Uterine Factor Infertility. METHOD: The method is not recognised as standard clinical care yet, there were only some 13 cases performed worldwide so far. There is only one clinical trial worldwide, which has proven both feasibility and also healthy child delivery. RESULTS: Czech Republic Ministry of Health permitted the uterus transplant clinical trial in 2015. The first phase of the surgical part includes performance and description of the uterus retrieval from a deceased donor. CONCLUSIONS: The first uterus retrieval from a deceased donor as a part of multi-organ retrieval was performed in the Czech Republic on January 13th, 2016; the case is described in the paper. KEY WORDS: uterus - transplantation - deceased - donor - retrieval.

OBJECTIVE: In 2008, a new technique of reinforced aneurysmorrhaphy with a polyester mesh tube for salvaging true aneurysmal arteriovenous (AV) haemodialysis access was described by us. In this study, the long-term patency and complication rates associated with this procedure were analysed, and the effect of reinforced aneurysmorrhaphy on high-flow vascular access was assessed. METHODS: This was a retrospective non-randomised study with prospectively collected data performed at a single centre. Patients with true aneurysmal haemodialysis AV access who underwent aneurysmorrhaphy with external mesh prosthesis between March 2007 and October 2012 were included. Clinical assessment and duplex ultrasound were performed preoperatively, 1, 3, and 12 months postoperatively, and annually thereafter. RESULTS: Data from 62 patients (median age 60 years, range 28-81 years; 63% men) were analysed. The commonest indication was high-flow vascular access associated with the risk of high output cardiac failure (24 patients, 39%). The mean follow-up time was 14.66 ± 12.80 months. Primary patency rates at 6 and 12 months were 86% and 79% respectively. Assisted primary patency rates at 6 and 12 months were 89% and 80% respectively. In 23 patients (96%) operated on for high-flow vascular access, decreased vascular access flow was observed after the procedure. The average flow reduction after aneurysmorrhaphy was 2,197 mL/minute. Postoperative bleeding and infection necessitating surgical revision occurred in three (4.8%) and three (4.8%) patients respectively. CONCLUSIONS: Reinforced aneurysmorrhaphy with an external mesh prosthesis is an effective method for treating true aneurysmal haemodialysis AV access, with excellent long-term patency and minimal complications due to infection.

We report five cases of early venous complications, all successfully rescued by graft removal, re-perfusion and re-transplantation, these kidneys would have been lost otherwise. All kidneys were from deceased donors, mean donor age was 39 years (range 29-55), with serum creatitine levels on harvesting being 81 µmol/l (65-108), glomerular filtration of 1.46 ml/s (0.82-1.83). Reasons for venous complications were following: Two cases of renal vein stenosis, another two with renal vein laceration, one renal vein thrombosis for unknown reason. All the five kidney grafts have been rescued successfully. One year's results in this group comes as mean serum creatinine level of 127 µmol/l. The described approach gives a chance to the patients with early vein thrombosis and offers the kidney graft salvage (Ref. 4).

An analytical method for studying DNA degradation by electrophoresis after cell lysis and visualization of DNA fragments with fluorescent dye, comet assay, was used to evaluate the viability of the endothelial layer of human arterial grafts with the aim of identifying the procedure that will least damage the tissue before cryopreservation. Four groups of samples were studied: cryopreserved arterial grafts that were thawed in two different ways, slowly lasting 2 hours or rapidly for approx. 7 minutes. Arterial grafts that were collected as part of multiorgan procurement with minimal warm ischemia time. Cadaveric grafts were taken as part of the autopsy, so they have a more extended period of warm ischemia. The HeadDNA (%) parameter and others commonly used parameters like TailDNA (%). TailMoment, TailLength, OliveMoment, TailMoment to characterize the comet were used to assess viability in this study. The ratio of non-decayed to decayed nuclei was determined from the values found. This ratio for cadaveric grafts was 0.63, for slowly thawed cryopreserved grafts 2.9, for rapidly thawed cryopreserved grafts 1.9, and for multi-organ procurement grafts 0.68. The results of the study confirmed the assumption that the allografts obtained from cadaveric donors are the least suitable. On the other hand, grafts obtained from multiorgan donors are better in terms of viability monitored by comet assay.

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). Early thrombosis developed in 2 of 10 (20 %) recipients, and thrombectomy and temporary viability preservation were achieved in both cases. However, re-thrombosis developed in both cases, and a graft hysterectomy was carried out. In recipient number 2, vascular changes might have contributed to graft thrombosis. The histopathological finding of the explant revealed subintimal excentric fibrosis with focal sclerotic changes. In recipient number 8, thrombosis was facilitated by external compression of the vascular pedicles by the hematoma as well as production of de novo donor-specific antibodies. Thrombosis led to graft loss in both cases despite an attempt at a thrombectomy. Therefore, the focus must be on prevention including a thorough evaluation of the donor candidate. In the postoperative course, perfusion is closely followed-up with an ultrasound, Doppler flow monitoring, and macroscopic evaluation of the cervix. In the event that findings are unclear, a relaparotomy should be promptly indicated. If thrombosis is revealed, a thrombectomy and an attempt to salvage the graft are indicated; however, the role of this strategy is questionable due to the low chance of long-term success. The indication of upfront graft removal and early re-transplantation in the treatment of uterine graft remains debatable.

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. Given the above, we sought to test RTC in relationship to macrophage polarization in the visceral AT (VAT) of living kidney donors (LKDs) and the effect of conditioned media obtained from their AT. The influence of ATCM on CE capacity was first assessed in an experiment where standard plasma was used as cholesterol acceptor from [14C] cholesterol labeled THP-1. Conditioned media as a product of LKDs' incubated AT showed no effect on CE. Likewise, we did not find any effect of individual plasma of LKDs on CE when individual plasma of LKDs were used as acceptors. On the other hand, we documented an effect of LKDs' adipose cell size on CE. Our results indicate that the pro-inflammatory status of human AT is not likely induced by disrupted RCT but might be influenced by the metabolic status of LKDs' adipose tissue.

AIM: Venous and arterial graft usage in vascular reconstructions was re-discovered in connection with organ transplantation development. Allografts are employed in many clinics, however, uniform opinion on the use of immunosuppression after the procedure of venous graft transfer from a cadaveric donor, is still lacking. MATERIAL AND METHODS: The authors present their own group of patients who underwent vascular reconstructions, and in whom allogenic vein was used. The majority of indications for bypass procedures resulted from critical limb ischemia. Immunosuppressive medication was administered during the vascular procedure and, over the past several years, it purely consisted of tacrolimus monotherapy. RESULTS: In the group of 101 patients, no serious complications due to adverse effects of immunosuppression therapy were recorded.

AIM: The aim of the study was to perform a retrospective assessment in a group of patients with portal vein thromboses who underwent consecutive liver transplantation. MATERIAL AND METHODS: PVT was preoperatively diagnosed with ultrasound and CT portography. The follow up period was 1 to 6 years. Postoperative immunosuppressive medication was administered in combination with cyclosporin A, prednison and imuran upon initiation of the transplantation programme (8 patients). During the follow up period, the treatment protocol was replaced with FK 506, Cell Cept and prednisone. Liver biopsy was indicated when rejection was suspected. RESULTS: During 1996-2009, the team of authors performed a total of 740 liver transplantations in 303 female and 437 male subjects. The procedures included 703 primary procedures, 33 retransplantations and four second retransplantations. Out of the total, 57 recipients (7.7%) had portal vein obliteration. These subjects included 42 male and 15 females, their mean age was 52 (9-67) years. 62 liver transplantations were performed in these 57 patients. The following complications were recorded in the patient group: graft dysfunction in 10.5%, revisions for bleeding in 28%, hepatic artery thrombosis in 10.5%, portal vein rethrombosis in 1.8%, biliary complications in 17.5%, acute rejections in 19.3%. Perioperative mortality rate was 15.8%.The mean blood derivates requirement was 17.1 (0-425) erythrocyte transfusion units, 27.1 (0-132) frozen plasma transfusion units and 2.6 (0-20) thrombocyte transfusion units. CONCLUSION: The results of out retrospective study indicate that portal thrombosis is not a contraindication for liver transplantation. Current surgical techniques make liver transplantations in patients with complete splanchnic venous thrombosis possible.

Acute limb ischemia is serious situation, jeopardizing limb salvage, causing embolization or thrombosis of the native arteries or vascular graft. Immediate surgical revascularization with balloon thromboembolectomy is indicated in patient with acute ischemia stage IIB of the Rutherford classification. Unfortunately, operative thromboembolectomy is frequently incomplete, with persistent thrombus remaining in the majority of patients. Residual thrombus compromises the clinical outcome, leading to poor revascularization and an increased risk of tissue loss. On depending of amount of the residual thrombus after surgical thromboembolectomy, we can choose one of the three options of intraoperative thrombolysis. This article summarized indication and technical realisation of intraoperative thrombolysis and describe cause report of the first patient treated with this method in our country. The combined use of intraoperative thrombolytics following mechanical thromboembolectomy is safe and efficacious method in patients with acute vascular occlusion.

INTRODUCTION: Biliary complications (BC) after liver transplantation (LTx) are serious problems with an incidence rate of 6-35%. There are two types of BC, early and late. Early BC is observed for 30 days post LTx or during the entire period of the patient's first hospital stay after LTx. The main causes of early BC are ischemia of the biliary tree (the bile duct of the transplanted liver is supplied only from the right hepatic artery descendingly; the supply from the gastroduodenal artery is lacking) as well as implementation of the biliary anastomosis surgical technique. Treatment of BC is administered by a surgeon, a gastroenterologist and a radiologist. AIM: To evaluate early biliary complications after LTx PATIENTS AND METHODS: We reviewed patients with early BC after LTx from 4/2004 - 12/2009. We defined early BC as a complication that is present during the first 30 days post LTx or during the entire period of the patient's first hospital stay after LTx. RESULTS: We performed 384 LTx during the above-mentioned period. We carried out reconstruction of the biliary tree in the form of a choledochocholedochostomy (CDD) in 312 cases and in the form of a choledochojejunostomy (CDJ) in 72 cases. Sixty-eight patients had early BC (17.7%), 25 patients experienced biliary leak (6.5%), 40 patients had anastomotic stenosis (10.4%) and 3 patients (0.8%) experienced both complications (biliary leak and stenosis). Most complications were eliminated by ERCP with a papilosfincterotomy, a balloon dilatation of stenosis, and a biliary stent implant with repeated stent replacements (45 cases in total- all patients with biliary stenosis). Twenty-two patients were reoperated on (16x CDJ, 3x re-CDD, 2x suture of aberrant bile duct, 1x suture common bile duct) and 1 patient was treated by percutaneous transhepatic bilary drainage (PTD). The mortality rate was zero. CONCLUSION: BC after LTx continue to pose a serious surgical problem. The treatment of choice when dealing with BC is ERCP, which has more than a 70% success rate. If ERCP or PTD are not successful, or when biliary peritonitis is present, we perform a reanastomosis of the bile duct. The combined effort of the surgeon, gastroenterologist and radiologist is the most important factor for successful treatment. The incidence of BC after LTx at IKEM is similar to that of treatment centers all over the world.
