Tytuł:: Endotension : a cause of failure in endovascular repair of abdominal aortic aneurysms
Wartość wtórnej rekonstrukcji obrazu angiografii wielorzędowej tomografii komputerowej w wymiarowaniu podnerkowych tętniaków aorty
Opis:: The phenomenon of aortic aneurysm enlargement after endovascular repair without detectable endoleak is called "endotension". It is caused by persistent pressurization within the excluded aneurysm sac and may cause subsequent rupture of the aneurysm. We undertake a review of current knowledge about causes, significance and treatment of endotension as a failure in endovascular aortic aneurysm repair. The goal of endovascular abdominal aortic aneurysm repair is to prevent aneurysm ruptures by excluding the aneurysms from the aortic circulation. AAA (Abdominal Aortic Aneurysm) after EVAR (Endovascular Aneurysm Repair) can enlarge even in the absence of detectable endoleak because of persistent pressurization within the excluded aneurysm. There are many theories about the mechanism of pressure transmission into the excluded aneurismal sac. Some laboratory and clinical research shows that endotension can be connected with attachment side failure, graft fabrics or aneurysm sac geometry. Pressure transmission by the thrombus, poor outflow, osmotic effect or ultrafiltration are the other possible mechanisms causing this phenomenon. Maximal diameter measurement by CT is considered to be the best management method in patients after EVAR. However, lack of aneurysm sac shrinkage observed in some cases does not mean the presence of endotension. The role of pulsatility inside the excluded aneurysm sac remains unclear. Several possible concepts of endotension treatment have been discussed, including both open surgical convention and nonoperative approach. The absence of endoleak after endovascular repair not always means that there is no pressurization within the aneurysm. Success of endovascular repair can be evaluated indirectly by observation of changes in the diameter of the aneurysm sac after EVAR. Thus, it is essential to follow up patients after endovascular repair in order to detect any late complications including endotension.

Opis:: Introduction: The patients with the aortic abdominal aneurysym of 55 mm in diameter are qualified to surgery. There are open repair (OR) by means of the vascular prosthesis implantation or the less invassive endovascular method by means of the stentgraft implantation through femoral arteries incision (EndovascularAorticRepair – EVAR). Aim: The aim of the study was the evaluation of the postoperative course in patients operated due to aortic abdominal aneurysm and the evaluation of the impact of the surgical method on the short-time results. Material and methods: 124 patients operated due to abdominal aortic aneurysm in Dept of Surgery of 4th Military Hospital in Wroclaw in 2014 were enrolled into the study: 53 patients with OR, 53 patients with EVAR, and 19 patients with ruptured aneurysm. Results: Mortality was 0% in EVAR and 6% in OR and 39% in ruptured aneurysm. Time of hospital stay was 5.8 days in EVAR vs 10 days in OR. The stay in ICU was 0% in EVAR vs 13% in OR. Blood transfusion was 9.4% in EVAR vs 66% in OR. Time of postoperative analgesia was 27 h in EVAR vs 76.8 h in OR. Cardio-respiratory decompensation was 1.9% in EVAR vs 7.6% in OR. Renal insufficiency was 2% in EVAR vs 9% in OR. The lower rate of organ complications was in EVAR. The ruptured aneurysm presented the most complicated postoperative course: hospital stay of 11.4 days, ICU stay of 78%, blood transfusion of 100%, painkillers of 136 hours, cardio-respiratory decompensation of 81% and renal insufficiency of 69%. Conclusions: The method of treatment, the conditions of the admision and the type of surgery influenced the postoperative course. The elective EVAR patients presented both the 0% of mortality and the lightest postoperative course. The ruptured abdominal aortic aneurysms operated as an emergency had the most complicated postoperative course.

Opis:: Aim: The aim of our study was to assess the outcomes of stent-graft coverage of the hypogastric artery in the management of aortoiliac aneurysms with endovascular aneurysm repair (EVAR). Material and methods: From January 2013 to March 2017, a total of 93 patients with aortoiliac aneurysms were treated with EVAR, which required occlusion of one or both of the hypogastric arteries. The patients of the Department of General, Vascular, Endocrine and Transplant Surgery were included in the study continuously and all procedures were elective. Results: A total of 93 patients with aortoiliac aneurysms required a unilateral or bilateral procedure. Six patients were excluded from our study because they did not appear at their follow-up appointments. The study included 87 patients (80 men; mean age 71.9 (7.9) years, range 54–88), of which 30 had a unilateral procedure and 57 had a bilateral procedure. In 8 procedures (5.55%, n = 7) there was a type II endoleak that resolved during follow-up and required no surgical intervention. In 10 procedures (6.94%, n = 10) there was a type IB endoleak, with 8 procedures requiring surgical re-intervention in the form of an extension. In 12 procedures (8.33%, n = 9), the hypogastric artery thrombosed. Conclusion: Coverage of the hypogastric artery by stent-graft has been proven to be a safe procedure, but there is still a risk of type II endoleak. Although 5.55% (n = 7) of the procedures in our study had a type II endoleak, none required surgical intervention.

Tytuł:: Iatrogenic pericallosal artery aneurysm after endovascular procedure

Opis:: Iatrogenic brain aneurysms are rare and are usually a result of direct trauma to the arterial wall during various neurosurgical or endovascular procedures. Single cases of pericallosal posttraumatic and postsurgical aneurysms were previously reported. Herein, we report the first confirmed case of iatrogenic pericallosal artery aneurysm caused by an arterial wall injury during the endovascular treatment of another aneurysm. A 50-year-old woman with ruptured anterior communicating artery aneurysm was initially treated with balloon-assisted coiling. During the procedure the tip of a microwire inserted into balloon catheter placed in the pericallosal artery caused a local injury of the inner layer of the vessel wall and vasoconstriction, without bleeding, dissection, or flow disturbances visible in digital subtraction angiography (DSA). Control examination revealed dissecting pericallosal aneurysm. After standard dual-antiplatelet oral preparation, stent-assisted coiling of the pericallosal artery aneurysm was performed with residual contrast filling of the base of the aneurysm sac in control angiography (RROC III). After 6 months the control DSA examination showed entirely cured pericallosal aneurysm (RROC I) and reconstruction of the parent artery. Successful endovascular treatment of an iatrogenic pericallosal aneurysm was previously reported, and this method seems to be the first-choice treatment. In our case, endovascular stent-assisted coiling also allowed for safe exclusion from circulation of pericallosal dissecting aneurysm, and the implanted stent caused reconstruction of the parent artery, restoring the normal lumen diameter. The second endovascular treatment option considered was implantation of a flow-diverted stent into the pericallosal artery.

Opis:: The endovascular method as a less invasive treatment for patients with abdominal aortic aneurysm (AAA) has become an alternative to conventional open surgery. The objective of the present study was to analyse the outcomes of endovascular treatment of AAA patients in long-term observation. A group of 236 AAA patients subjected to planned endovascular aneurysm repair (EVAR) between 2010 and 2015 was reviewed. Rates of mortality, surgical complications and re-interventions were collected in the separate time periods, i.e. up to 30 days after surgery, 30 days to 3 years, and from 3 to 5 years after surgery. Cumulative rates of these parameters were evaluated in the short-term (up to 30 days after surgery), medium-term (up to 3 years), and long-term (up to 5 years after surgery) perspective. The median age of patients was 75 years, and the most common comorbidities were arterial hypertension (54%) and ischaemic heart disease (52%). Cumulative short-, medium- and long-term mortality rates were 2.5%, 14.2% and 28.9%, respectively. Total rates of surgical complications in short-, medium- and long-term observation were 7.6%, 12.6% and 17.5%, respectively. The cumulative rate of re-interventions ranged from 4.2% to 11.4%. In the consecutive time periods, the increase in the percentage of surgical complications and re-interventions increased gradually, in contrast to mortality, where the curve grew significantly, which is expected due to the aging and numerous comorbidities in the observed group of patients.

Tytuł:: Percutaneous puncture and embolisation for pancreatitis-related pseudoaneurysm : the feasibility of thrombin injection even in collection of fluid surrounding the pseudoaneurysm

Opis:: Purpose: Pancreatitis-related pseudoaneurysm, a potentially life-threatening condition, is treated utilising endovascular management as a first choice and alternatively by percutaneous direct puncture of the aneurysm and embolisation. Case report: A 50-year-old man with alcohol-induced necrotic pancreatitis underwent transcatheter arterial embolisation (TAE) for multiple pancreatic pseudoaneurysms. TAE failed in one enlarged aneurysm in the pancreatic body, and percutaneous direct needle puncture and coagulation using thrombin was planned. Precise puncture of the aneurysmal sac under fluoroscopy and computed tomographic (CT) guidance failed, but we could inject about 500 units of thrombin through the outer cannula into the collection of fluid surrounding the aneurysm. Compared to preoperative images, contrast-enhanced CT (CECT) showed shrinkage of the pseudoaneurysm without complications just after the procedure and its disappearance five days after the procedure. Conclusions: Percutaneous direct puncture and embolisation is a feasible choice to treat pancreatic pseudoaneurysms, and injection of thrombin even into the collection of fluid surrounding the pseudoaneurysm can be a viable alternative, especially in cases in which precise puncture of the aneurysmal sac is difficult because of its size and location.

Opis:: Introduction. Bilatereal saccular cerebral aneurysms (SCAs) that developed symmetrically on the same named vessels are defined as mirror aneurysms and account for a small subset of multiple cerebral aneurysms. The internal carotid artery (ICA) bifurcation is a rare location for mirror aneurysms. Aim. We aimed to present the importance of risk status assessment for SCAs and screening in all ADPKD patients for timely detection and managementof SCAs before catastrophic complications occur. Description of the case. We present mirror aneurysms of bilateral ICA bifurcation that appear like a couple of dancing men on coronal computed tomography angiography (CTA) images, which were successfully treated with single stage coil embolization in a 45 year old female patient with medical history of autosomal dominant policystic kidney disease (ADPKD). Conclusion. SCAs are more frequent in patients with ADPKD than in general population and also these aneurysms are more likely to rupture at earlier ages. Mirror aneurysms of ICA terminus can be treated effectively and safely by single stage coil embolization.

Opis:: In the current case report we present a novel case of a successful coil embolization of the left internal carotid artery aneurysm. The patient presented with neck pain and a palpable pulsating tumor and was admitted to the vascular surgery clinic where an angio-CT scan of the neck was performed. Angio-CT revealed a left internal carotid artery aneurysm with a narrow neck. The patient was admitted to the department of vascular surgery where she was enrolled into endovascular coil embolization. After the procedure, control angiography showed complete embolization of the aneurysm. Three months following the procedure, doppler ultrasonography of the carotid arteries showed no demonstrable flow into the aneurysm. Six months following the procedure, angio-CT confirmed complete aneurysm thrombosis. Based on this case, endovascular coil embolization of the carotid artery aneurysms is a safe and effective method of treatment.
