RESUMEN

PURPOSE: This study investigated the 2-year safety and effectiveness of the PQ Bypass DETOUR system as a percutaneous femoropopliteal bypass. MATERIALS AND METHODS: Seventy-eight patients with 82 long-segment femoropopliteal lesions were enrolled in this prospective, single-arm, multicenter study. The DETOUR system deployed Torus stent grafts directed through a transvenous route. Eligible patients included those with lesions of >10 cm and average of 371±55 mm. Key safety endpoints included major adverse events (MAEs) and symptomatic deep venous thrombosis in the target limb. Effectiveness endpoints included primary patency defined as freedom from ≥50% stenosis, occlusion, or clinically-driven target vessel revascularization (CD-TVR), primary assisted, and secondary patency. RESULTS: Chronic total occlusions and severe calcium occurred in 96% and 67% of lesions, respectively. Core laboratory-assessed total lesion length averaged 371±51 mm with a mean occlusion length of 159±88 mm. The rates of technical and procedural success were 96%, with satisfactory delivery and deployment of the device without in-hospital MAEs in 79/82 limbs. The MAE rate was 22.0%, with 3 unrelated deaths (4%), 12 CD-TVRs (16%), and 1 major amputation (1%). Deep venous thrombosis developed in 2.8% of target limbs, and there were no reported pulmonary emboli. Primary, assisted primary, and secondary patency rates by the Kaplan-Meier analysis were 79±5%, 79±5%, and 86±4%, respectively. CONCLUSIONS: The PQ Bypass DETOUR system is a safe and effective percutaneous alternative to femoropopliteal open bypass with favorable results through 2 years. The DETOUR system provides a durable alternative to conventional endovascular modalities and open surgery for patients with long, severely calcified, or occluded femoropopliteal lesions.

RESUMEN

INTRODUCTION: Endovascular aneurysm sealing (EVAS) was commercially introduced in 2013. The initial results of EVAS were positive, leading to its widespread use. The mid- and long-term reports showed greater than expected rates of migration, which led to a recall of the device. In the present article, we describe our experience in managing type Ia endoleaks and migration occurring with the Nellix system in three different ways: open repair with Nellix explantation, Nellix-in-Nellix application (NINA technique), and the use of the multibranched Colt device originally dedicated to the treatment of thoracoabdominal aneurysms. MATERIALS AND METHODS: From February 2014 to June 2021, we performed 20 procedures for failed EVAS or ChEVAS (migration, type Ia endoleak, secondary aneurysm rupture). All patients treated for EVAS failure were male, aged 65 - 79. RESULTS: Seven Nellix explantations were performed. Three patients were admitted to our hospital with ruptured aneurysms that occurred 3 weeks to 4 years (mean 124 weeks) after EVAS, and another four with type Ia endoleak. In all but one case, removal of the Nellix system was easy. In two patients, tube grafts were implanted and in the remaining five cases, bifurcated grafts were implanted. In four patients, graft legs were anastomosed with the internal iliac arteries. One patient with secondary aneurysm rupture died from multiorgan failure on the 4th postoperative day. In two cases, transient renal failure was noticed in the perioperative period. All patients were admitted to the intensive care unit for 1 to 4 days (mean 2 days). The mean hospital stay was 9 days. All patients stayed in follow-up (3 - 56 months), but no other complications occurred. Eight patients were treated with the NINA technique: five for distal migration of the Nellix and three for failed ChEVAS. Four patients had a NINA procedure performed with three chimneys, three with two and one with one chimney. In one case, two iliac limbs were implanted to avoid kinking of the external iliac arteries. The median hospitalization time after the procedure was 9 days (range 3 - 12). Four patients developed transient acute renal insufficiency in the perioperative period. The follow-up ranged between 4 and 72 months. In one patient, deterioration of preexisting chronic renal insufficiency developed 5 months after the procedure, but dialysis was not required. One patient died from exacerbation of heart failure 7 months after the NINA procedure. The Colt device was implanted in five patients for the treatment of distal migration with type Ia endoleaks. None of the patients developed any signs of spinal cord ischemia. All patients were admitted to the intensive care unit for 1 or 2 days. In two cases, transient acute renal failure was noticed in the perioperative period. The mean hospital stay was 9 days. All patients remained in follow-up (6 - 22 months). In one case, the occlusion of the celiac trunk branch was found in contrast computed tomography 1 month after implantation of the Colt device, but without any symptoms. No other complications occurred. CONCLUSIONS: Normal strategies for the management of complications for late failure of EVAR, including stent-graft extensions, are not suitable after EVAS; therefore, alternatives are necessary. Conversion to open repair carries an extensive burden on the patient, so it is not recommended for patients with high surgical risk. The use of a Nellix-in-Nellix application to treat late failure of EVAS is not within the instructions for use but could be an effective strategy for a type Ia endoleak with or without migration. The use of this technique has been extremely limited since the Nellix system was recalled from the market. The use of the Colt multibranched device may be an alternative option, but due to the small number of patients, this method needs further evaluation.

RESUMEN

OBJECTIVE: The objective of this study was to evaluate the 1-year safety and effectiveness outcomes associated with the PQ Bypass DETOUR System (PQ Bypass, Milpitas, Calif) for the percutaneous bypass of long-segment femoropopliteal occlusive disease. METHODS: This prospective, single-arm, multicenter trial enrolled patients with long-segment femoropopliteal arterial disease. The DETOUR System percutaneously deploys modular stent grafts to bypass femoropopliteal lesions through a transvenous route. Eligible patients included those with TransAtlantic Inter-Society Consensus C and D lesions >100 mm in length. The primary safety end point was the major adverse event (MAE) rate through 1 month, defined as the composite of death, clinically driven target vessel revascularization (CD-TVR), or major amputation. The primary effectiveness end point was stent graft patency through 6 months, defined as freedom from stenosis ≥50%, occlusion, or CD-TVR. RESULTS: During a 24-month period, 78 patients (82 limbs) were enrolled. The average core laboratory-measured lesion length was 371 ± 55 mm; 79 of 82 lesions (96%) were chronic total occlusions, and 55 of 82 lesions (67%) had severe calcification. The rates of technical and procedural success measured during the index procedure were both 96%, with satisfactory delivery and deployment of the device without MAEs in 79 of 82 limbs. Through 1 month, there were no deaths or amputations; CD-TVRs occurred in 2 of 81 limbs (3%), and freedom from MAEs was 98% (79/81). The 1-year Kaplan-Meier primary, assisted primary, and secondary patency rates were 81% ± 4%, 82% ± 4%, and 90% ± 3%, respectively. The ankle-brachial index increased an average of 0.25 ± 0.27 between baseline and 1 year (P < .001). Through 1 year, the Kaplan-Meier estimates of freedom from stent graft thrombosis, CD-TVR, and MAE were 84% ± 4%, 85% ± 4%, and 84% ± 4%, respectively. At 1 year, the Rutherford class improved in 77 of 80 limbs (96%), and 65 of 80 (81%) were asymptomatic. Deep venous thrombosis developed in 2 of 79 target limbs (3%) through 1 year, both at the femoropopliteal vein level. There were no instances of pulmonary embolism. CONCLUSIONS: The 1-year results from the DETOUR I trial show that the PQ Bypass DETOUR System is a safe and effective percutaneous treatment option for patients with longer, severely calcified, above-knee femoropopliteal lesions.

RESUMEN

BACKGROUND: The 1-year results of the use of the Nellix (Endologix Inc, Irvine, Calif) endovascular aneurysm sealing (EVAS) device were initially promising. However, midterm complications including migration and aneurysm growth occurred more frequently than expected, which provided an incentive to refine the instructions for use. Strategies for the management of complications arising after endovascular aneurysm repair are often not applicable for EVAS, given the unique configuration of the Nellix device, and new techniques are needed. This study analyzes the clinical outcomes of both elective and emergency deployment of a new Nellix device within a primarily placed device, for failure of EVAS, which we refer to as a Nellix-in-Nellix application (NINA). METHODS: This is a global, retrospective, observational cohort study focusing on the early outcome of NINA for failed EVAS, including data from 11 European institutions and 1 hospital in New Zealand. RESULTS: A total of 41 patients were identified who underwent a NINA procedure. Of these, 32 (78%) were placed electively and 9 (22%) were placed on an emergency basis. Seven patients were initially treated with chimney EVAS (n = 5 in the elective NINA group and n = 2 in the emergency NINA group). The average time between the primary EVAS procedure and NINA was 573 days (interquartile range, [IQR] 397-1078 days) and 478 days (IQR, 120-806) for the elective and emergency groups, respectively. The indication for elective NINA was endoleak with migration (50%), endoleak without migration (25%), migration without endoleak (16%), and other (9%). Chimney grafts were used in 21 of 32 patients in the elective group and 3 of 9 patients in the emergency group. Technical success was achieved in 94% of patients in the elective group and 100% of patients in the emergency group. At latest follow-up (median, 104 days; IQR, 49-328 days), there were three aneurysm-related deaths (9%), no ruptures, and five device-related reinterventions (16%) within the elective group. In the emergency group (median follow-up, 23 days; IQR, 7-61 days), there were four aneurysm-related deaths and three aneurysm-related reinterventions. CONCLUSIONS: In conclusion, a NINA can be used to treat late failures of EVAS with an acceptable technical success rate and can be used when more established treatment options are unfeasible or contraindicated. The durability of this technique needs to be further reviewed.

RESUMEN

The infection of a vascular prosthesis is potentially fatal, and its effective treatment still remains the greatest challenge for vascular surgeons. We present our initial experience using bovine pericardial vascular prostheses to replace infected aortoiliac vascular grafts. Six consecutive patients with infection of the graft were prospectively included in this study. Infection of the vascular graft was confirmed by clinical symptoms, laboratory tests and the results of computed tomography and positron emission tomography/computed tomography. In all cases, the infected aortoiliac graft was surgically removed and replaced by the bovine-pericardial BioIntegral aortic-bifemoral prosthesis. Technical success was achieved in every case with no in-hospital or 30 days mortality. One patient required revision of distal anastomosis due to recurrent bleeding at day four after surgery. One patient presented with upper gastrointestinal tract bleeding during the postoperative period, which was managed endoscopically. The mean hospital stay was 14 days (range 9-19). The control CT scan performed 2 months after surgery showed significant regression of abscesses and periprosthetic inflammation. Two patients died within 32 months of follow-up: one due to heart attack, the other due to generalized sepsis, which was correlated with the previous infection. Four patients are still in follow-up. The BioIntegral prosthesis is patent in all four cases, with no clinical or ultrasonographic signs of infection. Our brief investigation shows that a bovine pericardial prosthesis may be a valuable option in the treatment of vascular grafts infections.

RESUMEN

OBJECTIVES: At 12 months follow up of the PLIANT study, clinical success and efficacy of the E-liac Stent Graft System (JOTEC GmbH, Hechingen, Germany) were evaluated. Clinical success was defined as aneurysm exclusion (no type I, III, IV endoleak) with primary patency of the internal iliac artery (IIA) and external iliac artery (EIA) on the E-liac implantation side. METHODS: In this prospective multicentre European observational study, clinical and morphological data of 45 patients (93% male, mean age 72 y) were prospectively collected in 11 European centres between July 2014 and June 2016. Forty patients underwent an aorto-iliac (three patients bilaterally) treatment and five an isolated iliac treatment. RESULTS: At 12 months follow up, data were available for 42 patients. Overall clinical success at 12 months was 90%, with a survival rate of 100%. Four patients (10%) did not achieve clinical success, one with an internal iliac artery (IIA) occlusion on the E-liac implantation side, one with an infrarenal type Ia endoleak, and two with type Ib endoleaks in IIA. At 12 months the primary patency rate in the internal iliac artery on the iliac side branch implantation side was 98%. Two patients (5%) received E-liac related re-interventions: one caused by an edge stenosis at the distal end of the graft limb in the external iliac artery (EIA) and one caused by thrombo-embolism in the external iliac artery. Thus, for the EIA, primary and secondary patency rates were 98% and 100%, respectively. CONCLUSIONS: The low device related re-intervention rate of 5%, the high survival rate of 100%, and the high primary patency rates of 98% for the IIA and EIA at 12 month follow up demonstrate the safety and efficacy of the E-liac Stent Graft System. Long term 36 month results are awaited to confirm the efficacy and durability.

RESUMEN

PURPOSE: To investigate the outcomes of patients who were treated for thoracoabdominal aortic aneurysms (TAAAs) using custom-made fenestrated-branched stent-grafts. METHODS: A consecutive series of 108 patients (mean age 73.5 years; 73 men) with TAAA were treated with E-xtra Design Engineering customized fenestrated-branched stent-grafts between November 2011 and January 2017. Data on baseline characteristics, procedures, and clinical follow-up were collected from 6 regional European surgical centers for retrospective analysis of endoleaks, reinterventions, and target vessel patency. The median aneurysm diameter was 6.75 cm (range 5.5-13). The distribution of the TAAA according to the modified Crawford classification of extent was 25 (24%) type I, 19 (17%) type II, 20 (18%) type III, 29 (27%) type IV, and 15 (14%) type V. RESULTS: Technical success was achieved in 95% (103/108) of cases. Major early perioperative complications occurred in 40 (37%) patients. The 30-day mortality was 9.2% (10/108), and perioperative spinal cord ischemia was observed in 6 (5.5%) patients [2 (1.8%) permanent]. During the mean follow-up of 17.6 months (range 3-52), 28 (26%) patients required late reintervention. Two patients died due to aneurysm- or procedure-related causes. The estimated survival rates at 1, 2, and 4 years were 87%, 84%, and 51%, respectively. The estimated target vessel patency rates at the same time points were 95%, 91%, and 90%, respectively. The freedom from reintervention estimates were 84% and 73% at 1 and 4 years, respectively. CONCLUSION: Endovascular repair of TAAA using Jotec customized fenestrated-branched stent-grafts appears to be safe and effective in the early to midterm. The considerable rate of secondary interventions indicates that further improvements, graft surveillance, and follow-up are required.

RESUMEN

OBJECTIVES: To study the safety and feasibility of the E-liac Stent Graft System® in patients with aorto/iliac aneurysms. METHODS: A prospective multicentric European registry of patients receiving the E-liac Stent Graft System® was conducted. Endpoints of the study included the technical success as well as periprocedural events and 30-day endoleaks, reinterventions, internal and external iliac artery patency and mortality. RESULTS: Between July 2014 and June 2016, a total of 45 patients (93% men, mean age 72 years, range 53-90 years) were enrolled at 11 sites in four European countries. Five patients received an isolated iliac treatment. Thirty-seven patients were treated with a combination of an abdominal stent graft and a unilateral E-liac and three in combination with bilateral E-liac. All E-liac Stent Grafts (48) were implanted in the intended position and the internal iliac arteries were successfully bridged. Two patients did not receive clinical success, due to endoleak type Ia of the aortic stent graft. At 30-day follow-up, clinical success rate was 96%. Three successful endovascular reinterventions were performed within the 30-day follow-up: one due to a type Ia endoleak in the common iliac artery, one due to type Ia endoleak of the aortic stent graft, and one due to bilateral lower limb claudication provoked by stent graft limb stenosis. At 30-day, a 100% survival rate and complete absence of pelvic or buttock ischemia/claudication were reported. Primary patency at 30 days was 100% for the internal iliac artery and 98% for the external iliac artery with an assisted patency of 100% in the latter. CONCLUSIONS: The high clinical success rate, low rates of device-related reinterventions (2%), and excellent patency rate demonstrate the safety and feasibility of the E-liac Stent Graft System. Long-term results are awaited to state efficacy and durability. Clinical Trials.gov. Identifier no. NCT02209194.

RESUMEN

PURPOSE: To report the results of the ASCEND Registry of cases involving endovascular aneurysm sealing (EVAS) in combination with chimney grafts (chEVAS) for the treatment of para- and juxtarenal aortic aneurysms (AAA). METHODS: A retrospective, multicenter registry established in 8 vascular centers between 2013 and 2016 recorded the treatment results and follow-up of chEVAS procedures for nonruptured AAAs; data were analyzed using standardized outcome measures. In the observation period, 154 patients (mean age 72.3±7.7 years; 124 men) underwent elective treatment for de novo juxtarenal and pararenal aneurysms and formed the study group. RESULTS: Sixty-two (40.3%) of the cohort were treated using a single parallel graft, 54 (35.1%) with double chimneys, 27 (17.5%) with triple chimneys, and 11 (7.1%) with 4 chimneys. The 30-day mortality was 2.8%, and there were 4 perioperative strokes (1 fatal). At 1 year, the freedom from all-cause mortality was 89.8% and the freedom from aneurysm-related mortality was 94.3%. There were 3 endoleaks within 90 days of the procedure, one type Ia and 2 type Ib. The freedom from type Ia endoleaks was 95.7% at 1 year. There were no types II or III endoleaks in this series; the freedom from all endoleaks was 94.2% at 1 year. Freedom from reintervention at 1 year was 89.2%. Target vessel patency rates at 1 year were 97.7%, 99.3%, 100%, and 100% for the left renal, right renal, superior mesenteric artery, and celiac axis stents, respectively. CONCLUSION: The ASCEND Registry supports a proof of concept for the use of polymer technology and EVAS with parallel grafts in managing patients with complex aortic disease. The future role of chEVAS will be defined by studies that assess mid- to long-term durability.

RESUMEN

Andexanet alfa (AA) is a recombinant inactive analog of human activated factor X (FXa), effectively reversing the effects of its inhibitors - rivaroxaban and apixaban, which are available in Poland. The drug was approved for clinical use registration after the publication of the results of the ANNEXA-4 trial (Andexanet Alfa, a Novel Antidote to the Anticoagulation Effects of FXa Inhibitors 4), in which its efficacy in restoring hemostasis in life-threatening hemorrhages in patients receiving using the aforementioned anticoagulants was demonstrated. Hence, AA is now recommended for patients on apixaban or rivaroxaban therapy with massive and uncontrollable hemorrhages, including hemorrhagic strokes (HS) and gastrointestinal bleeding. Drug-specific chromogenic anti-Xa assays are generally best suited for estimating rivaroxaban and apixaban plasma levels, aside from direct assessment of their concentrations. The absence of anti-Xa activity, determined using these assays, allows us to rule out the presence of clinically relevant plasma concentrations of any FXa inhibitor. On the other hand, the dose of AA should not be modified based on the results of coagulation tests, as it depends solely on the time that elapsed since the last dose of FXa inhibitor and oon the dose and type of FXa inhibitor. AA is administered as an intravenous (i.v.) bolus, followed by an i.v. infusion of the drug. The maximum reversal of anti-Xa activity occurs within two minutes of the end of the bolus treatment, with the continuation of the continuous i.v. infusion allowing the effect to be maintained for up to two hours afterwards. Because anticoagulant activity can reappear after the infusion is completed, it is currently unclear at what point after AA administration FXa inhibitors or heparin should be re-administered. In Poland AA is starting to become available and its urgent need to administer it to patients with severe bleeding on apixaban or rivaroxaban.

RESUMEN

OBJECTIVES: Our goal was to evaluate results of endovascular aortic arch repair using the Relay Branch system. METHODS: Forty-three patients with thoracic aortic pathology involving the aortic arch have been treated with the Relay Branch system (Terumo Aortic, Sunrise, FL, USA) in 10 centres. We assessed in-hospital mortality, neurological injury, treatment success according to current reporting standards and the need for secondary interventions. In addition, outcome was analysed according to the underlying pathology: non-dissective disease versus residual aortic dissection (RAD) (defined as remaining dissection after previous type A repair, chronic type B aortic dissections). RESULTS: In-hospital mortality was 9% (0% in patients with RAD). Disabling stroke occurred in 7% (0% in patients with RAD); non-disabling stroke occurred in 19% (7% in patients with RAD). Early type IA and B endoleak formation occurred in 4%. Median follow-up was 16 ± 18 months. During the follow-up period, 23% of the patients died. Aortic-related deaths were low (3% in patients with RAD). CONCLUSIONS: The results of endovascular aortic arch repair using the Relay Branch system in a selected patient population with regard to technical success are good. In-hospital mortality is acceptable, the number of disabling strokes is low and technical success is high. Non-disabling stroke is a major concern, and every effort has to be taken to reduce this to a minimum. The best outcome is seen in patients with underlying RAD. Finally, more data are needed.

RESUMEN

OBJECTIVES: To evaluate the impact of the coronavirus disease 2019 (COVID-19) pandemic on acute and elective thoracic and abdominal aortic procedures. METHODS: Forty departments shared their data on acute and elective thoracic and abdominal aortic procedures between January and May 2020 and January and May 2019 in Europe, Asia and the USA. Admission rates as well as delay from onset of symptoms to referral were compared. RESULTS: No differences in the number of acute thoracic and abdominal aortic procedures were observed between 2020 and the reference period in 2019 [incidence rates ratio (IRR): 0.96, confidence interval (CI) 0.89-1.04; P = 0.39]. Also, no difference in the time interval from acute onset of symptoms to referral was recorded (<12 h 32% vs > 12 h 68% in 2020, < 12 h 34% vs > 12 h 66% in 2019 P = 0.29). Conversely, a decline of 35% in elective procedures was seen (IRR: 0.81, CI 0.76-0.87; P < 0.001) with substantial differences between countries and the most pronounced decline in Italy (-40%, P < 0.001). Interestingly, in Switzerland, an increase in the number of elective cases was observed (+35%, P = 0.02). CONCLUSIONS: There was no change in the number of acute thoracic and abdominal aortic cases and procedures during the initial wave of the COVID-19 pandemic, whereas the case load of elective operations and procedures decreased significantly. Patients with acute aortic syndromes presented despite COVID-19 and were managed according to current guidelines. Further analysis is required to prove that deferral of elective cases had no impact on premature mortality.

RESUMEN

The objective of this study was to assess the efficacy and safety of liposomal heparin spray-a new formula of topical heparin delivery. This was a randomized, multicenter, controlled open clinical trial with 2 parallel groups. Forty-six outpatients with clinical signs of superficial venous thrombosis (SVT) were treated with either topical liposomal heparin spraygel (LHSG) (Lipohep Forte Spraygel, 4 puffs of 458 IU tid (n = 22) or with low-molecular-weight heparin (LMWH) (Clexane 40 mg once a day (n = 24), administered subcutaneously (sc). Main outcome measures were efficacy parameters (improvement of local symptoms-pain control and planimetric evaluation of erythema size, duplex Doppler assessment of thrombus regression) and safety parameters (documentation of adverse events, with particular reference to deep vein thrombosis [DVT] by duplex sonography, and patients' and investigators' assessment of drug tolerance). Patients' and investigators' subjective assessment of efficacy of treatment and change in basic biochemical parameters were defined as secondary outcome measures. Statistical analysis was performed with use of Wilcoxon test, Mann-Whitney U-test and Chi-square test. Regression of SVT-related symptoms, including pain, erythema, and thrombus presence, was shown as comparable in LHSG and LMWH groups. These results were corroborated by efficacy assessment by investigators and patients. Three cases of deep venous thrombosis in heparin spraygel and 1 in heparin sc group were reported. No significant adverse reactions were observed in the spraygel group, but 1 serious allergic reaction was observed in the LMWH group. Tolerance of new formula heparin was assessed as good. Heparin spraygel-a new topical mode of heparin application, seems a promising method of heparin delivery. This initial study has demonstrated comparable efficacy and safety of LHSG and LMWH in local treatment of SVT. These findings should be confirmed by further extensive study that will reach appropriate statistical power to support such conclusion, for despite heparin treatment, significant risk of DVT was demonstrated in both groups.

RESUMEN

Inherited factor VII (FVII) deficiency is a rare autosomal recessive hemorrhagic disorder. The major clinical symptoms include: bleeding from the oral cavity, epistaxis, menorrhagia, spontaneous hemarthros, bleeding to the gastrointestinal tract and central nervous system, and perioperative bleeding. The aim of this study was to present our experience in preventing bleeding and hemorrhagic disorders in surgical patients with inherited FVII deficiency by using recombinant activated FVIIa (rFVIIa), and with prothrombin complex concentrates (PCCs). In 2002-2011, 17 patients with inherited FVII deficiency underwent surgery. Thirteen patients had isolated FVII deficiency below 10%, and four patients 10-25. To prevent bleeding and hemorrhagic complications, we administered small single doses of rFVIIa (Novo-Seven) at 12-h intervals to 15 patients on surgery day and on day 1 following surgery, then every 24 h; PCCs were administered (Prothromplex, Beriplex) to two patients. No symptoms of bleeding, hemorrhagic or thromboembolic complications were observed in the perioperative and 1-month observation period in surgical patients treated with rFVIIa. One patient treated with PCC (Prothromplex) developed distal deep vein thrombosis on postoperative day 7. The results suggest that small, single, every 12-h doses of rFVIIa (NovoSeven) and in next days after surgery one time every 24 h are well tolerated and effective for prevention of thromboembolic, bleeding and hemorrhagic complications in FVII-deficient patients. Antithrombotic prophylaxis with low-molecular-weight heparin should be applied in patients using PCCs.

RESUMEN

Osteolysis of vertebrae due to inflammatory aortic aneurysm is rarely observed. However, it is estimated that up to 10 % of infectious aneurysms coexist with bone tissue destruction, most commonly the vertebrae. Inflammatory aneurysms with no identified infection factor, along with infiltration of adjacent muscle and in particular extensive destruction of bone tissue have rarely been described in the literature. A case of inflammatory aneurysm with posterior wall rupture and inflammatory infiltration of the iliopsoas muscle and spine, together with extensive vertebral body destruction, is presented. The aneurysm was successfully treated with endovascular aneurysm repair EVAR.

RESUMEN

A case of femoral artery obstruction following application of a StarClose type arterial puncture closing device (APCD) is presented. Ultrasonographic and angiographic imaging of this complication was obtained. The posterior wall of the vessel was accidentally caught in the anchoring element of the nitinol clip. This complication was successfully resolved by endovascular treatment and the implantation of a stent.

RESUMEN

The aim of the study is to present our own perioperative bridging therapy with low molecular weight heparin (LMWH) for surgical patients with thrombophilia on long-term acenokumarol therapy [oral anticoagulant (OAC)]. In some European countries, the drug used in secondary antithrombotic prophylaxis is acenokumarol. Forty-two patients with inherited thrombophilia and 21 with antiphospholipid syndrome underwent surgery. All patients were on long-term OAC. This OAC was interrupted 2 days before elective surgery and since that day half of the individual therapeutic dose of LMWH was administered. On day of surgery, the LMWH therapeutic dose was divided into two parts. Starting with day 2 after surgery, the patient was again given half of the individual dose of LMWH every 24 h. On day 4, OAC was additionally included. Both drugs were administered until stabilization of international normalized ratio (INR) values within the therapeutic target for 2 consecutive days. LMWH was then interrupted, whereas OAC continued. No symptoms or episodes of venous thromboembolism were observed. No intraoperative or postoperative hemorrhagic complications were reported. The results suggest that our perioperative bridging therapy is safe and effective for prevention of thromboembolic and hemorrhagic complications.

RESUMEN

Visceral aneurysms are potentially life-threatening vascular lesions. Superior mesenteric artery (SMA) pseudoaneurysms are a rare but well-recognized complication of chronic pancreatitis. Open surgical repair of such an aneurysm, especially in patients after previous surgical treatment, might be dangerous and risky. Stent graft implantation makes SMA pseudoaneurysm exclusion possible and therefore avoids a major abdominal operation. Percutaneous direct thrombin injection is also one of the methods of treating aneurysms in this area. We report a first case of percutaneous ultrasound-guided thrombin injection to complete SMA pseudoaneurysm exclusion after an unsuccessful endograft placement. Six-month follow-up did not demonstrate any signs of aneurysm recurrence.
