RESUMO

INTRODUCTION: Acute symptomatic occlusion of the internal carotid artery (ICA) is associated with unfavorable prognosis. However, no clear definition of its optimal treatment exists. The aim of this study was to evaluate the efficacy and risks of urgent carotid endarterectomy (CEA) in patients with ischemic stroke due to acute extracranial ICA occlusion. METHODS: A retrospective analysis was performed of all consecutive patients undergoing urgent CEA for acute extracranial ICA occlusion during the period from July 2014 to June 2021. The primary outcome was functional independence at three months defined as modified Rankin Scale (mRS) score 2. Secondary outcomes included the severity of the neurological deficit at the time of discharge and its comparison with the preoperative condition as assessed using the National Institutes of Health Stroke Scale (NIHSS), the incidence of symptomatic intracerebral hemorrhage (ICH), and 30-day periprocedural mortality. RESULTS: During the study period, a total of 42 urgent CEAs were performed for acute extracranial ICA occlusions. The median preoperative NIHSS score was 7 (interquartile range [IQR] 5-13). The median time interval between the onset of symptoms and surgery was 290 minutes (IQR 235-340). Technical success rate of urgent CEA was 97.6% (41 patients). The median NIHSS at the time of hospital discharge was 2 (IQR 3-7; p.

RESUMO

INTRODUCTION: Visceral artery aneurysms are rare vascular pathologies. They are usually incidental findings during the examination for other reasons. The most common clinical symptoms are nonspecific abdominal pain and bleeding caused by their rupture, with a severe clinical presentation. Aneurysms of pancreaticoduodenal arcade are more common in patients with well-developed collateral circulation due to the coeliac trunk stenosis or occlusion. CASE REPORT: In this case report the authors present a rare case of a patient with incidental finding of pancreaticoduodenal arcade aneurysm in the setting of severe stenosis of coeliac trunk origin caused by medial arcuate ligament compression. The diameter of the aneurysm was 40 mm and endovascular treatment was not possible because of unfavorable anatomical setting. The patient was successfully treated with resection of the aneurysm and the division of medial arcuate ligament during one surgery. CONCLUSION: There is no correlation between the diameter and the risk of rupture of the pancreaticoduodenal arcade aneurysm. Because of high morbidity and mortality of their rupture, most authors recommend active treatment of these aneurysms. The necessity to treat truncus coeliacus stenosis or occlusion remains a controversial issue.

RESUMO

PURPOSE: Retrospective evaluation of 12-year experience with endovascular management of acute mesenteric ischemia (AMI) due to embolic occlusion of the superior mesenteric artery (SMA). MATERIALS AND METHODS: From 2003 to 2014, we analysed the in-hospital mortality of 37 patients with acute mesenteric embolism who underwent primary endovascular therapy with subsequent on-demand laparotomy. Transcatheter embolus aspiration was used in all 37 patients (19 women, 18 men, median age 76 years) with embolic occlusion of the SMA. Adjunctive local thrombolysis (n = 2) and stenting (n = 2) were also utilised. RESULTS: We achieved complete recanalization of the SMA stem in 91.9 %. One patient was successfully treated by surgical embolectomy due to a failed endovascular approach. Subsequent exploratory laparotomy was performed in 73.0 % (n = 27), and necrotic bowel resection in 40.5 %. The total in-hospital mortality was 27.0 %. CONCLUSION: Primary endovascular therapy for acute embolic SMA occlusion with on-demand laparotomy is a recommended algorithm used in our centre to treat SMA occlusion. This combined approach for the treatment of AMI is associated with in-hospital mortality rate of 27.0 %.

RESUMO

Salmonellosis is a significant cause of foodborne gastroenteritis in Australia, and rates of illness have increased over recent years. We adopt a Bayesian source attribution model to estimate the contribution of different animal reservoirs to illness due to Salmonella spp. in South Australia between 2000 and 2010, together with 95% credible intervals (CrI). We excluded known travel associated cases and those of rare subtypes (fewer than 20 human cases or fewer than 10 isolates from included sources over the 11-year period), and the remaining 76% of cases were classified as sporadic or outbreak associated. Source-related parameters were included to allow for different handling and consumption practices. We attributed 35% (95% CrI: 20-49) of sporadic cases to chicken meat and 37% (95% CrI: 23-53) of sporadic cases to eggs. Of outbreak-related cases, 33% (95% CrI: 20-62) were attributed to chicken meat and 59% (95% CrI: 29-75) to eggs. A comparison of alternative model assumptions indicated that biases due to possible clustering of samples from sources had relatively minor effects on these estimates. Analysis of source-related parameters showed higher risk of illness from contaminated eggs than from contaminated chicken meat, suggesting that consumption and handling practices potentially play a bigger role in illness due to eggs, considering low Salmonella prevalence on eggs. Our results strengthen the evidence that eggs and chicken meat are important vehicles for salmonellosis in South Australia.

RESUMO

Osteochondromas (exostoses) are the most common benign bone tumours. In most cases, osteochondroma occurs as a solitary lesion. Hereditary multiple osteochondromatosis is an autosomal dominant disorder manifested by multiple exostoses most commonly located at the metaphyses of long bones, the iliac crest, the ribs, the vertebral borders, and scapulas. Vascular complications of multiple osteochondromatosis are very rare, most frequently affecting the popliteal artery. The authors report the case of a 27-year-old female patient with hereditary multiple osteochondromatosis that was complicated by femoropopliteal deep vein thrombosis and giant popliteal artery pseudoaneurysm.

RESUMO

Popliteal artery entrapment syndrome is a rare cause of lower limb ischaemia. It is caused by an abnormal relationship between popliteal artery and its surrounding musculotendineous structures (anatomic entrapment). Functional popliteal entrapment is characterized by normal anatomic relationships within popliteal fossa. The true incidence is unknown, it usually affects young patients, typically men, and is clinically presented with symptoms of calf claudication, calf cramping, coldness and paresthesia. CT angiography and MR angiography have become an imaging technique of choice. The mainstay surgical procedure is popliteal artery release. In cases of popliteal artery damage autologous saphenous vein bypass grafting offers the best long-term results. Authors on the basis of two case reports describe the clinical course, diagnosis and surgical technique used in the treatment of patients with advanced popliteal artery entrapmentsyndrome.

RESUMO

PURPOSE: To evaluate effectiveness and safety of hypogastric artery branches embolization in the treatment of postpartum hemorrhage, hemorrhage associated with cesarean section and termination of pregnancy. MATERIALS AND METHODS: All women with intractable bleeding and who were treated by embolization, were included from the period between 1996 to 2010. The retrospective study included 16 women of mean age 30.5 years. RESULTS: Intractable hemorrhage related to regular delivery occurred 7 times, five times after cesarean section and four times after termination of pregnancy. Seven women (44%) were in hemorrhagic shock during therapeutic embolization. Extravazation was angiographically proved in 50% cases. Embolization was successful in hemorrhage control in 87,5% of women, in two women embolization was repeated for persistent bleeding. There were 21 additional surgical procedures performed in 13 women before embolization including 2 hysterectomies. Two hysterectomies were done after embolization because of infection. In remaining 3 women embolization was done as a primary method of bleeding control. No patient died. In the group of 10 women with maximally 1 surgery before embolization length of hospital stay was 10.1 days in average, while in a group of six women having 2 to 3 surgeries before embolization the hospital stay was 21.2 days in average (p = 0.03). CONCLUSION: Embolization of hypogastric arteries decreases length of hospital stay in patients with obstetric hemorrhage and should be done soon if routine methods of bleeding control fail.

RESUMO

AIM: To analyze survival of patients after TIPS (transjugular intrahepatic portosystemic shunt). PATIENT SAMPLE AND METHODOLOGY: Between September 1992 and August 2010, TIPS was created in 848 patients of the University Hospital Hradec Kralove. These patients were divided into groups. Survival was analyzed using Kaplan-Meier survival curves. Differences between groups were evaluated using log-rank test. RESULTS: Ten percent of patients do not survive one month after TIPS, 40% of patients survive 5 years and 20% of patients survive 10 years. There were statistically significant differences between groups divided according to Child-Pugh classification (A vs B p = 0.0053; B vs. C p < 0.0001), indication for surgery [prevention of bleeding recurrence differed from refractory ascites (p = 0.0001) and the indication to stop acute bleeding (p = 0.026)]; aetiology of the liver disease [patients with alcoholic cirrhosis differed from patients with Budd-Chiari syndrome (p < 0.0001) and from patients with chronic viral hepatitis (p = 0.024)]. CONCLUSION: Survival of patients after TIPS is influenced by Child-Pugh score, indication and aetiology of the liver disease.

RESUMO

Authors describe a case report of complications and theirs solutions after endovascular abdominal aneurysm repair. There was symptomatic progression of aneurysmal sac due to endoleak type Ib in this patient 4 years after successful stentgraft treatment. Endovascular treatment was done with optimal effect, but aneurysm sac rupture had early become. The patient was urgently operated. The cause of the rupture was endoleak type IIIa, that was diagnosed perioperatively. This complication was solved with direct suture of disconnected parts of stentgraft. Despite of postoperative complications the patient vas released home in a good condition after 23 days of hospital staying. Endoleaks and their management are discussed in the article.

RESUMO

INTRODUCTION: Patients with celiac axis stenosis are asymptomatic due to the rich collateral blood supply through superior mesenteric artery. Ligating and dividing gastroduodenal artery during pancreatoduodenectomy can cause ischemic threat especially to liver, less frequently stomach and spleen, or failure of anastomoses. CASE REPORT: The authors present a case of 27-year-old female who underwent duodenopancreatectomy for pseudopapillary tumour of the head of pancreas. Celiac axis stenosis was found peroperatively and proven during angiography. Although an attempt of endovascular dilatation of celiac axis was unsuccessful, blood supply to the liver was sufficient and therefore we did not perform any other intervention to improve blood flow to the liver. Postoperative course was uneventful. DISCUSSION: Celiac axis stenosis can be caused by tumour infiltration or lymphadenopathy in malignant disease, atherosclerosis or compression of the median arcuate ligament. The stenosis can be managed by endovascular treatment or arterial reconstruction. In conclusion the authors propose a management algorithm to prevent the consequences of celiac axis stenosis.

RESUMO

BACKGROUND: Primary aldosteronism is one of the most common forms of secondary arterial hypertension. Adrenalectomy is effective in patients with proven unilateral hypersecretion of aldosterone whereas pharmacotherapy is indicated in bilateral forms of the disease. We can meet the opinion that in patients with confirmed primary aldosteronism and finding ofsuprarenal adenoma > or = 1 cm on computed tomography (CT) scanning, adrenalectomy can be recommended without further investigation. On the other hand we can perform adrenal venous sampling (AVS) to prove unilateral overproduction of aldosterone. OBJECTIVES: To evaluate whether AVS is necessary in all patients with unilateral adenoma > or = 1 cm. METHODS: We analyzed data from patients with proven primary aldosteronism, CT finding of adenoma > or = 1 cm along with normal morphology of contralateral adrenal gland, and successfully performed AVS. RESULTS: Out of 107 patients with proven primary aldosteronism, indicated for AVS, we included 30 patients with CT finding of suprarenal adenoma > or = 1 cm along with normal morphology of contralateral adrenal gland and successful AVS. Unilateral overproduction of aldosterone was found only in 17 cases (56.7%), the results in remaining 13 patients (43.3%) did not confirm activity of adenoma. CONCLUSION: Our results support necessity of performing AVS in all patients with primary aldosteronism in whom surgical treatment is considered, CT confirmation ofan adenoma is insufficient in this indication.

RESUMO

AIM: To evaluate the feasibility of liver blood outflow (LBOF) occlusion and its impact on the effectiveness of radiofrequency ablation (RFA). METHODS: The experiment was performed on 10 pigs. The animals were divided into groups A and B according to RFA protocol. In group A (n=5) the RFA time was that taken to reach the target temperature of 105 degrees C, whereas group B (n=5) had a constant RFA temperature of 105 degrees C and constant time of 8min. The liver blood flow (LBF) was quantified using Doppler ultrasonography before LBOF occlusion and after that. RFA were performed using an expandable 3cm RF needle. Two liver ablations created in different liver lobes were compared; the first ablation was created before balloon inflation and the second one was created under LBOF occlusion. The time required for RFA procedure, liver ablation volumes, shape and microscopic changes of the thermoablated zones were recorded. RESULTS: The LBF dropped significantly in all liver vessels after balloon inflation. The volume of the ablated area was 8.2+/-2.2cm(3) and increased significantly after LBOF occlusion to 17.4+/-3.8cm(3) (p<0.001), in group A. A significant enlargement of the ablated area with occluded LBF was registered in group B, it was 6.7+/-2.8cm(3) versus 19.4+/-1.8cm(3) respectively (p<0.01). CONCLUSIONS: Temporary LBOF occlusion led to a significant reduction in liver blood flow, enlargement of the thermoablated area volume and homogeneity of the coagulated zones.

RESUMO

BACKGROUND: Percutaneous transluminal angioplasty and stenting with cerebral protection is a minimally invasive method for carotid artery stenosis treatment, which may be an alternative to surgical endarterectomy. The aim of our study is to evaluate results of endovascular treatment in patients at high risk of endarterectomy. PATIENTS AND METHODS: Between years 2001-2006, 210 carotid artery stenoses in 204 patients were treated in our department. Fourty seven percent of patients suffered from symptomatic stenosis, asymptomatic stenosis was proved in 53% of patients. All asymptomatic patients had stenosis more than 70% measured according to NASCET, mostly with contralateral carotid artery occlusion. RESULTS: The procedure was technically successful in 99% of patients, mortality was 0.49%. Periprocedural embolic complications based on transient ischemic attack were observed in 2.39% of patients, symptoms of minor stroke in 0.47% and symptoms of major stroke in 0.47% of patients. The mortality and disabled morbidity rate in the whole group was 0.96%. One hundred and fifty three patients (73%) were followed up, during this time, 7 patients (3.9%) developed hemodynamically significant restenosis. CONCLUSION: Endovascular carotid artery stenosis treatment with cerebral protection seems to be a safe method of treatment with acceptable short-term results. However, long-term follow-up is needed to get enough data about safety and effectiveness of this method compared to endarterectomy and best medical therapy.

RESUMO

Authors present the case report of the pseudoaneurysm of deep femoral artery caused by the injury of the vessel wall during the open femur fracture. This fracture was primarly treated by repoisition and stabilization by the external fixator (Rohr system, Synthes GmbH, Switzerland), which was nine days later converted into the intramedullar osteosynthesis by the unreamed nail UFN (Synthes GmbH, Switzerland). The first clinical signs of the pseudoaneurysm occurred several days after the patient had been dismissed. In the clinical picture there dominated the painful swelling of thigh but no perfusion or innervation disorders in the periphery of the extremity were noticed and the finding was concluded as myositis ossificans. Proper diagnosis was set only 6 weeks later on the basis of the ultrasound and angiographic investigations. The situation was then solved by the angiographic embolization of pseudoaneurysm. In the discussion also other opinions from the literature are presented.

RESUMO

OBJECTIVE: Retrospective evaluation of the effect of secondary insertion of ePTFE-coated stent in the treatment of TIPS dysfunction versus other current options (simple angioplasty, insertion of additional non-coated stent). PATIENT SET AND METHODOLOGY: From the beginning of 2000 to the end of 2004, there were 121 interventions for TIPS dysfunction performed in our centre in which a non-coated stent was used to make up the shunt at the time of intervention. Depending on the type of intervention, the patient set was divided in 4 groups: simple angioplasty (52 cases, 43%), insertion of non-coated stent (35 cases, 28.9%), insertion of non-dedicated ePTFE-coated stent (15 cases, 12.4%), and insertion of dedicated ePTFE-coated stent (19 cases, 15.7%). All patients were monitored on a regular basis after the intervention for shunt patency with the use of clinical examination and Doppler ultrasonography, or also portal venography. Primary shunt patency after the intervention was evaluated in all four groups by Kaplan-Meier analysis. The primary shunt patency results after the intervention were compared with the use Cox F text and logrank test. RESULTS: The intervention was successful in 120 cases (the overall technical success rate of all interventions was 99.2%). The primary shunt patency was 49.7 % after 12 months and 25.3 % after 24 months following sole angioplasty intervention; 74.9% after 12 and 64.9% after 24 months following intervention involving the insertion of non-coated stent; 75.2 % after 12 months and 64.5% after 24 months following intervention involving the insertion of non-dedicated ePTFE-coated stent, and 88.1% after 12 months and 80.8% after 24 months following intervention involving the insertion of a dedicated ePTFE-coated stent. A statistically significant improvement in shunt patency was obtained in the group of interventions involving the insertion of dedicated ePTFE-coated stent and in the group of interventions involving the insertion of non-coated stent as compared with the group of interventions involving sole angioplasty (p < 0.01). CONCLUSION: From among all the currently used methods of therapeutic intervention for TIPS dysfunction, the best, the best subsequent TIPS patency was obtained after intervention involving insertion of dedicated ePTFE-coated stent.

RESUMO

BACKGROUND: The aim of the study is to present results of a prospective uncontrolled clinical study. Percutaneous vertebroplasty or kyphoplasty are minimally invasive methods based on polymethylmethacrylate (PMMA) bone cement application into the damaged vertebra. This leads to decrease of the pain and vertebral body stabilisation. Oncology disorders of the spine are relatively common, having a wide alternative of various methods of treatment. Patients, according to their findings and indication criteria, are treated surgically or conservatively, oncological treatment is usually based on radiotherapy. Authors discuss the role of these invasive procedures in the treating algorithm of patients with spinal metasthases and multiple myeloma. METHODS AND RESULTS: From September 2003 to December 2005, 21 percutaneous vertebroplasties in 14 patients, mean age 68.7 (47-80) year, were performed in our department. During one treatment session 1-2 vertebrae (total of 21 vertebrae) in level Th9 - L5 were treated. Vertebroplasties and kyphoplasty were performed under fluoroscopy guidance. Transpedicular acces was used. Totally, 3 asymptomatic complications were proved. As first, a bone cement leaked paravertebrally during L5 body treatment, as second, a bone cement leaked into paravertebral veins, and as third, a bone cement leaked into the intervertebral space. Visual analog scale (VAS) was 8.9 points before procedure, 1.9 point 3 months after procedure and 2.6 points 6 months after procedure. We did not prove a symptomatic or total complication. CONCLUSIONS: According to our experience, percutaneous vertebroplasty is an effective alternative treatment of painful oncologic spine disease.

RESUMO

We report our experience with two cases of endovascular treatment of penetrating aortic ulcers (PAU). The first patient was a 71-year-old woman with 30 mm width aortic ulcer accompanied by intramural hematoma of the descending thoracic aorta. The second patient was an 80-year-old obese woman with 50 mm pseudoaneurysma of the abdominal aorta, which was result of PAU. Both patients were successfully treated by means of tubular stentgraft, implanted from surgical cut down of the right femoral artery. Penetrating aortic ulcer represents localized, potentially lethal pathology of the aorta. Together with dissection and intramural hematoma belongs among the acute aortic syndromes. During nature course PAU can progress to the acute classic dissection, pseudoaneurysma or rupture of the aorta. It is principally disease of elderly hypertensive patients. Early diagnosis and appropriate therapy improves prognosis of patients with PAU. Open surgical repair with synthetic graft has been the gold standard of treatment but endovascular therapy is an attractive option in risk elderly patients. It seems to be a safe, effective treatment but stability of results of this method should be proved.

RESUMO

BACKGROUND: Moderate and severe hemoptysis is a potential life-threatening condition which requires immediate medical examination and intervention. AIM: Retrospective evaluation of the effectiveness of bronchial artery embolization in the management of hemoptysis (over 50 ml per 24 hours) in the university hospital (from 1998 to 2005). METHODS: A retrospective case study. Forty seven consecutive patients with hemoptysis over 50 ml per 24 hours were reviewed and data collected from medical documentation (medical history, chest X-ray, bronchoscopy, thorax spiral CT, pulmonary and bronchial angiography). RESULTS: Forty seven patients, 34 men and 13 women aged between 19-87 years, mean age of 57.1 years, were included in this study. All patients had clinically important hemoptysis (more than 50 ml blood in 24 hours), 23 patients 50-200 ml, 14 patients 200-500 ml, 10 patients over 500 ml. Twenty eight patients had reccurent hemoptysis and nineteen patients had the first stage of hemoptysis. Within the study group we recorded the following clinical causes of hemoptysis: 12 COPD with bronchiectasis, 11 pulmonary malignancy, 11 idiopatic hemoptysis, 5 arterioarterial shunts, 3 pneumonia, 2 aspergillomas, 1 posttuberculous scars, 1 pulmonary trauma, 1 pulmonary arteriovenous malformation. All 47 patients underwent angiography. Thirty seven bronchial artery embolizations (BAE) were performed on the side with greater bronchoscopy and CT abnormality. Polyvinyl-alcohol (sponge particles 45-350 pm) or acrylate glue were used as embolizing agents. We did not observe any complication during this procedures (BAE). Immediate success i.e. cessation of hemoptysis was achieved in 36 patients (97%). Follow-up lasted 4-63 months (33 patients). BAE resulted in long-term success i.e. no recurrent hemoptysis for 28 patients (85%). CONCLUSION: Transcatheter bronchial artery embolization is an effective and safe procedure for patients suffering from clinically important hemoptysis. Short-term control of hemoptysis can be achieved in 97% and long-term control in 85% of cases. Bronchial artery embolization is a treatment which can reduce the need for acute thoracic surgery.

RESUMO

Percutaneous vertebroplasty is a therapeutic, interventional radiologic procedure originally developed in France by Galibert, Deramond et al. (1987). The technique consists of the percutaneous puncture of the affected vertebral body, followed by injection of bone cement into a vertebral body for the relief of pain, and the strengthening of the bone. The procedure was used initially to treat aggressive hemangiomas, but it then was extended to the treatment of osteolytic metastases, multiple myeloma and osteoporotic compression fractures refractory to medical therapy. In this article we review the current techniques, indications for this procedure, preoperative and postoperative evaluations.

RESUMO

BACKGROUND: Traumatic injuries of the thoracic aorta are very frequent during motor vehicle accidents with sudden deceleration. Spiral CT has become the modality of choice for evaluating significant blunt trauma and grading system for aortic injury has been developed. Immediate diagnosis, introduction of antihypertensive therapy and endovascular treatment by means of stentgraft give a better chance for patients with blunt aortic injury. AIM: Prospective evaluation of results of endovascularly treated patients with blunt aortic injury. MATERIALS AND METHODS: We prospectively followed patients after endovascular treatment of acute aortic injury. Diagnosis was based on chest x-ray and CT examination. Stentgrafts were placed under fluoroscopic guidance and patients were routinely followed by CT and clinical visit. RESULTS: Between December 1999 and September 2004 we endovascularly treated seven patients (6 men, 1 woman, mean age 41.7 years) for blunt aortic injury of the thoracic aorta. Stentgraft was implanted between 5 hours and 6 days (mean 3.2 days) after injury. Seven stentgrafts were implanted in 7 patients in total. One patient died due to failure of endovascular technique for collapsed stentgraft. A new onset of lower legs paraparesis was detected in one patient. Other five patients are regularly followed (3-55 months, mean 30.7 months) without any complications. CONCLUSION: Endoluminal technique can be used successfully in the immediate repair of aortic trauma. At present time in our center, treatment by means of the stentgraft placement is the first line therapy in injured patients. It allows rapid stabilization of aortic trauma and further treatment of other injuries.
