ABSTRACT
The simultaneous occurrence of an abdominal aortic aneurysm and liver cirrhosis needing surgical treatment is extremely rare. There is still controversy regarding the timing of abdominal aortic aneurysm repair and liver transplantation and regarding optimal treatment of the aneurysm. Here, we describe a 70-year-old white male patient who presented with end-stage liver disease secondary to chronic hepatitis C with a solitary hepatocellular carcinoma measuring 5.5 cm in diameter in the right liver lobe. A pretransplant work-up resulted in discovery of a 6.7-cm abdominal aortic aneurysm. The decision was made to perform orthotopic liver transplantation with simultaneous aneurysm repair. The patient was initially explored through a median laparotomy. The liver transplant was performed first with the graft prepared on the back table using a standard procedure. The liver graft was transplanted using a "piggy-back" technique with end-to-side caval and end-to-end portal vein anastomosis. The arterial anastomosis was performed with an end-to-end anastomosis between the donor's proper hepatic artery and the recipient's common hepatic artery. The bile duct anastomosis was performed with an end-to-end anastomosis. A midline incision was extended to the pubis. After proximal and distal vascular control of the infrarenal aorta, resection of the abdominal aortic aneurysm was performed followed by reconstruction with an InterVascular 22-mm prosthesis using 3.0 Prolene in a running fashion. Eight days after surgery, the patient was discharged and remained well during the 2-year follow-up. Although rare, in a patient with end-stage liver disease and abdominal aortic aneurysm, a simultaneous liver transplantation and aneurysm repair procedure represents the safest treatment solution.

Imaging the pregnant patient presents a unique challenge to radiologist due to the risk of radiation to the conceptus (embryo/fetus). A rare case of a successfully recognized and treated pseudoaneurysm (PA) of the abdominal aorta is to be presented. The pseudoaneurysm occurred in the third trimester and had a favorable outcome for the mother and the baby. Emergent abdominal ultrasound (US) is the first modality in diagnostic algorithm for the rupture of aortic aneurysm in a pregnant woman. It provides the most rapid diagnostic information, although intestinal gas and abdominal tenderness may limit its accuracy. To confirm the findings, magnetic resonance angiography (MRA) or CT angiography (CTA) can be used. In our case, the diagnosis was established using a color Doppler ultrasonography of the abdomen and was later confirmed by a low dose CT scan of the abdominal aorta. MRA in such cases have some disadvantages. At many health centers, the monitoring of patients with acute ruptures is more difficult in the MR suite than at the CT scanner. MRA angiographic images are also subject to degradation by multiple artifacts and the visualization of the distal vasculature is suboptimal and inferior to the one done by CTA. Due to fetal movements, a small quantity of fresh blood can be overlooked by MR. MRA is often not available on a 24-hours basis, and the time required for making a diagnosis can preclude the use of MRA in an unstable patient. For this reason, we used a low dose CTA protocol to confirm the diagnosis. Low dose scanning protocols in CT can obtain sufficient diagnostic information while reducing the risk of radiation. A particular focus is put on the outline of new concepts for dose management and optimization. We used new approaches based on tube current modulation. The birth was induced by an urgent Caesarean section followed by a resection of a pseudoaneurysm and a reconstruction of the aorta with an end-to-end vascular prosthesis.

Carotid body paraganglioma has considerable malignant potential and locally aggressive behavior, so it should be treated as soon as it is discovered.We report the case of 60-year-old male patient with a carotid body paraganglioma (Shamblin group II) that was causing the carotid arteries to spread. Angiography showed 1 dominant feeding artery arising from the right external carotid artery. Selective angiography was performed 2 days before surgical removal of the tumor, and the feeding artery was successfully embolized with coils.Literature review reveals previous reports where preoperative embolization of the feeding arteries was done using ethanol, polymers, or other liquid agents. In our case, angiography (via femoral artery) was performed 2 days before surgical removal of the tumor, and the main feeding artery (a single branch arising from external carotid artery) was successfully embolized with coils rather than liquids.Performing coil embolization before operating reduced subsequent blood loss and made it easier to identify the feeding artery during surgery. Supraselective coiling, although as difficult as embolization with liquids, may reduce the incidence of postoperative stroke. At 1 year after surgery, the patient had no signs of tumor recurrence.

Summary. The development of the Guidelines for perioperative prophylactic use of antimicrobial agents (further on Guidelines) was initiated by the Interdisciplinary Section for Antibiotic Resistance Control (ISKRA) of the Croatian Ministry of Health and Social Welfare in accordance with the principles of AGREE (Appraisal of Guidelines for Research and Evaluation) methodology which means that the guidelines are the result of a consensus between all involved professional societies. Guidelines were composed in order to improve antibiotic use in surgical professions. Data obtained from observational studies have shown that the use of antimicrobials in surgical professions is unsatisfactory, and since around 50% of all prescribed drugs in surgical professions refer to perioperative prophylaxis, such guidelines could significantly improve current negative trend and reduce the occurrence of infections in surgical patients as well as slow down the selection of resistant bacteria. In the introductory part of the guidelines, principles of perioperative prophylaxis are presented. The advantages and risks of prophylaxis are listed as well as factors that determine prophylaxis effectiveness. For easier orientation, surgical professions have been divided into basic surgical fields. In each field, the specificity of the field has been described followed by uniform structured tables and with every listed surgical procedure there is the most probable cause of infection, the drug of choice for prophylaxis, alternative drug, remark for particular surgical procedure and finally the grade of recommendation. The Guidelines do not cover perioperative prophylaxis in immunocompromised patients nor perioperative prophylaxis in children. The Guidelines do not cover all possible surgical interventions, but can be used as a basis for most surgical procedures performed in our hospitals. At the very end of these Guidelines, a comprehensive list of references enables all those interested to find further information and details about this topic. The revision of the Guidelines is planned in three years' time.

Internal carotid artery (ICA) aneurysms are rare. The symptoms are related to cerebral embolization, local compression and rupture. Options for treatment include open surgery or endovascular treatment with a covered stent. We report a case of a 67 year old woman with bilateral idiopathic internal carotid artery aneurysms, found during the diagnostic evaluation for an episode of syncope. The right ICA aneurysm was treated with resection and end-to-end anastomosis of the ICA. There were no perioperative complications. Six months later the patient underwent endovascular repair of left carotid artery aneurysm with a covered stent. There were no complications in postoperative period. Treatment options for ICA aneurysms are surgical or endovascular, depending of size, location and anatomic relation to surrounding structures.

In this study we presented benefits of minimally invasive approach (MIAS) for treating abdominal aortic aneurysm (AAA) and aortoiliac occlusive disease (AIOD). MIAS technique consisted of minilaparotomy approach using incision length of 7-12 cm, intraabdominal small bowel retraction and standard aortic reconstruction with terminoterminal anastomosis or aortobifemoral bypass. Between December 2004 and January 2007 we perfomed 32 repairs for AAA and AIOD using MIAS technique. Mean infrarenal aortic cross clamp time was 48.5 +/- 17 minutes. Duration ofnasogastric suction and period before starting liquid diet was meanly 1.2 +/- 0.5 days. Mean time of stay in intensive care unit was 1.3 +/- 0.6 days, and hospital stay was 7.1 +/- 1.4 days. We had no 30-day mortality rate and there was no wound infection. MIAS technique is a safe method for the treatment of infrarenal AAA and AIOD including smaller wound size, shorter duration of postoperative ileus, intensive care unit stay and hospital stay, and lower hospital costs compared with those of standard way of treatment.

BACKGROUND: Chronic anal fissure is a lineal ulcer of the lower part of the anal canal. It is a painful condition characterized by postdefecational pain and bleeding. It is associated with internal anal sphincter spasm. The relief of internal anal sphincter spasm is the key for providing fissure healing. Gold standard in the treatment of chronic anal fissure is partial lateral internal anal sphincterotomy. METHODS: Sixty patients with chronic anal fissure were randomly assigned into two groups treated either by surgical sphincterotomy or injections of botulinum toxin into internal anal sphincter. Manometric measurements were performed before and three months after treatment. Follow up period was six months. The aim of the study was to compare results between these two groups. RESULTS: Both methods efficiently reduced resting anal pressure and successfully healed chronic anal fissure. CONCLUSION: Surgical and biologic sphincterotomy are almost equally effective in the treatment of chronic anal fissure. Injecting botulinum toxin into internal anal sphincter is a safe, easy to apply and effective method in the management of anal fissure.

The aim of this prospective study was to determine the prevalence and localization of stenotic atherosclerotic lesions of supra-aortic arteries in diabetic patients according to age and sex. Angiograms obtained by digital subtraction angiography were analyzed in 150 diabetic patients (study group) and 150 non-diabetic patients (control group) with symptoms of cerebral ischemia. Diabetic patients were found to have a significantly higher prevalence of stenotic atherosclerotic lesions of the internal carotid artery. Lesions of the large supra-aortic arteries were significantly more common in the left than in the right side of the neck (p < 0.001), but the difference between the diabetic and the non-diabetic group did not reach statistical significance. Hemodynamic conditions were found to be more important than diabetes for the occurrence of atherosclerotic lesions in these arteries. Changes in the proximal segment of the left common carotid artery were the most common finding in diabetic patients, hence attention should be paid to this localization on control examinations.

Gastrointestinal stromal tumors (GISTs) are characterized with diverse clinical presentations, including acute and chronic gastrointestinal bleeding, abdominal pain, presence of an intra-abdominal mass, anorexia, and intestinal obstruction. A 60-year-old obese woman presented as an acute abdominal emergency with right lower quadrant (RLQ) pain and tenderness, nausea and leukocytosis, all mimicking acute appendicitis. Laparotomy revealed a spontaneously ruptured GIST of the jejunum, which was localized to the RLQ due to postoperative adhesions following previous two cesarean sections and cholecystectomy. Complete surgical resection was performed, followed by an uneventful early postoperative course.
