RESUMO
CLINICAL ISSUE: Isolated iliac artery aneurysms occur considerably less often than abdominal aortic aneurysms. Mainly older men are affected by this disease. Most of these aneurysms are asymptomatic and are incidentally detected during cross-sectional imaging. Iliac aneurysms with a diameter larger than 3â¯cm are at risk for rupture, which is associated with high morbidity and mortality. STANDARD TREATMENT: To prevent their rupture as well as for symptomatic or ruptured aneurysms, endovascular treatment has recently been established as the primary approach due to the decreased morbidity and mortality compared to open repair. Endovascular aneurysm exclusion is performed with stent grafts, and depending on the anatomy, by adjunctive internal iliac artery embolization. TREATMENT INNOVATIONS: Up to a quarter of treated patients will require additional endovascular revisions during the long term. Reliable imaging follow-up likely increases the safety of elective or emergent endovascular iliac artery aneurysm repair.

INTRODUCTION: Acute haemodynamic changes and/or loss of abdominal muscle tone can occur during induction of general anaesthesia and may be the Achilles' tendon in endovascular aneurysm repair (EVAR) of ruptured aortoiliac aneurysms (rAIA). The purpose of this study was to evaluate the use of local anaesthesia (LA) for EVAR to overcome these limitations. METHODS: Twenty-one consecutive patients with rAIA are included in this study. Twenty patients underwent EVAR under LA, and 1 patient was treated under general anaesthesia. Haemodynamics were stabilised during assessment of EVAR feasibility by CT-scan and during the procedure itself by controlled hypotension (MAP 50-60 mmHg) and moderate fluid resuscitation. RESULTS: Median procedure time was 120 min. Haemodynamics remained stable in all but 3 patients who required transfemoral balloon occlusion of the supra-renal aorta. Perioperative intubation was necessary in 5 patients because of respiratory distress (n = 3), or retroperitoneal access (n = 2). Temporary deterioration of renal function occurred in 6 patients, with 2 requiring hemofiltration. CT-scan confirmed sealing of the rAIA in all patients at discharge. 30-day mortality was 9.5% (2 deaths). In the median follow-up of 19 months, there were no deaths, but 3 endovascular re-interventions, 1 crossover femoro-femoral bypass, and 1 open surgical graft repair. DISCUSSION: Our series is the first to show that EVAR for rAIA can be safely performed under LA. This approach allows implantation of commercially available bifurcated SG and improves patient outcome.
RESUMO

BACKGROUND: Controversy exists about the choice of treatment for patients with hypertrophic obstructive cardiomyopathy. The purpose of this study was to evaluate clinical and echocardiographic long-term results in patients with hypertrophic obstructive cardiomyopathy after septal myectomy and to determine predictors of event-free survival in these patients. METHODS: Between 1965 and 1995, 110 consecutive patients 2 to 66 years old (mean age, 37 +/- 15 years) with an invasively measured left ventricular outflow tract gradient of 86 +/- 39 mm Hg (81 +/- 42 mm Hg by Doppler echocardiography) underwent either septal myectomy only (n = 87) or myectomy combined with additional procedures (n = 23). Mean follow-up was 11.7 +/- 7.5 years. Predictors of late events were calculated using multivariate Cox regression analysis. RESULTS: The perioperative mortality rate was 3.6% (n = 4). The cumulative survival rate at 5, 10, and 15 years was 93%, 80%, and 72%, respectively, and symptom-free survival, 77%, 50%, and 33%, respectively. Predictors of late death were New York Heart Association class III or IV (p < 0.05), congestive heart failure (p < 0.05) and additional procedures (p < 0.05). The left ventricular outflow tract gradient was nearly eliminated in all patients, the left atrial dimension decreased significantly during the early years, and left ventricular dilatation occurred late in 17 patients. CONCLUSIONS: Septal myectomy is associated with a low perioperative mortality and a high late survival rate (72% at 15 years' follow-up). Septal myectomy is still an excellent modality in the treatment strategy for symptomatic patients with hypertrophic obstructive cardiomyopathy.

BACKGROUND: Arteriosclerotic plaques of the ascending aorta and transverse arch increase the operative risk of cardiac operations and are strong predictors for late cerebrovascular events. METHODS: Twenty-two patients, mean age 68 +/- 6 years (range, 55 to 77 years), with grade IV + V plaques of the ascending aorta and transverse arch underwent coronary artery bypass grafting (n = 21) and aortic valve replacement (n = 8). Cerebrovascular emboli from unknown sources were found preoperatively in 8 patients (36%). All were in sinus rhythm. Complete thromboendarterectomy of the ascending aorta and transverse arch was performed during hypothermic circulatory arrest. After 21 +/- 12 months (range, 4 to 44 months), magnetic resonance imaging and transthoracic echocardiography of endarterectomized vessels was performed. RESULTS: There was one perioperative death (4.5%), one early (4.5%), and one late (4.7%) adverse neurologic event. Follow-up examinations revealed normal diameters of the endarterectomized aorta. CONCLUSIONS: For patients with grade IV + V plaques, thromboendarterectomy of the ascending aorta and transverse arch can be performed with an acceptable surgical risk and a low recurrence rate for cerebrovascular events. Dilatation of the endarterectomized aorta was not observed.

BACKGROUND: In acute type A dissection of the aorta, local repair with glue-aortoplasty was compared with aortic replacement. METHODS: Between 1992 and 1996, 106 consecutive patients (mean age, 59 years; 84 men) were operated on average 14.5 hours after onset of dissection. A local repair (gelatin-resorcine-formaldehyde/glutaraldehyde glue, Trigon AG, Monchengladbach, Germany) without graft replacement was performed in 21 patients. Graft replacement and reinforcement of aortic stumps with gelatin-resorcine-formaldehyde/glutaraldehyde glue was performed in 85 patients (supracoronary graft, 68; aortic root replacement, 17). RESULTS: Survival was 79% after 30 days and 69% after 2 years. There was no difference in early mortality (p = 0.2240) and survival (p = 0.07649). Risk factors for early mortality were preoperative shock, neurologic disorder, duration of crossclamp, and extracorporeal circulation. The rate of reoperation on the proximal aorta was 31.6% (6 of 19) after local repair and 9% (6 of 64) after aortic replacement (p = 0.0157). Local repair was a significant predictor for reoperation (p = 0.0087), with decreased reoperation-free survival (p = 0.01164). In all reinterventions (four supracoronary grafts, including two valve replacements; two composite grafts; two arch replacements) breakdown of the aortoplasty was confirmed. CONCLUSION: Local repair has satisfactory early results but an increased incidence of reoperations due to a breakdown of the glue-aortoplasty. Indications for local repair should be restricted to high-risk patients requiring a minimal emergency surgical procedure.

The design of the Excluder, which is considered a 3rd generation device for endovascular repair of abdominal aortic aneurysms, is described. Based on a literature search, clinical short- to mid-term results are reviewed. So far, efficacy and safety of the Excluder for elective and emergent aneurysm repair have been demonstrated. In none of the studies perioperative conversion to open surgery or late aneurysm rupture has been reported. The cumulative 30-day-mortality rate was below 1%. Compared to the other commercial devices, aneurysm shrinkage is less marked after repair with the Excluder. Whether this is inconvenient remains to be proven on long-term follow-up.

Bilateral common iliac artery (CIA) aneurysms are rare, but more frequently symptomatic than abdominal aortic aneurysms (AAA). In elderly patients with coexisting medical problems, transluminal and/or endovascular procedures are preferred to avoid the risk of morbidity and mortality associated with further general anesthesia and surgery. However, bilateral internal iliac artery (IIA) occlusion during endovascular repair might be associated with significant morbidity, including gluteal claudicatio, and ischemia of the sigmoid colon and perineum. In the presented case report we describe the successful repair of bilateral CIA aneurysms by a total transluminal and endovascular approach. The potentially reversible embolisation of the less diseased IIA with detachable latex balloons preceded the implantation of a bilateral endovascular Y-stent. Both CIA aneurysms were successfully excluded from circulation. No complications were noted and the patient could be discharged four days after surgery. Probationary detachable balloon embolisation of the IIA followed by implantation of an endovascular bifurcated stentgraft is a safe technique. It allows clinical monitoring of acute ischemic complications before bilateral IIA occlusion by the stentgraft. In comparison to coil embolisation these balloons may be easier to remove if for instance, an external-internal iliac artery bypass is needed. Percutaneous balloon puncture might be another option to reverse acute ischemia.

BACKGROUND: Bleeding is a common and often severe side-effect in vascular surgery. The use of glue is widely accepted to achieve a dry surgical field. The application of sealant is limited when the surface is covered with blood. Aim of this study was to evaluate a new sealant (FloSeal) in patients undergoing vascular surgery. PATIENTS AND METHODS: Between June 1998 and July 1999 a total of 17 patients with peripheral vascular interventions was included in this investigation. Effectiveness was measured by bleeding severity prior and after application, time to hemostasis, amount of fusion matrix necessary for hemostasis, the potential need for additional hemostatic measures, or the need for reoperations to control the bleeding. RESULTS: In 15 out of 17 patients bleeding was controlled with FloSeal alone, two patients required further surgical or hemostatic treatment. There were no local or systemic complications after use of this product. CONCLUSION: FloSeal is an advantageous hemostatic tool.

BACKGROUND: To evaluate spiral computed tomography (SCT) angiography for assessment of feasibility of endovascular aneurysm repair (EVAR) in patients with ruptured aortoiliac aneurysm (AAA). PATIENTS AND METHODS: 24 patients (mean age 74 years; range, 69 to 82 years) with suspicion of ruptured AAA and stable hemodynamics were preoperatively examined by using a SCT scanner in the emergency room. SCT angiography was performed from the suprarenal aorta to the femoral bifurcation after a fixed injection delay time of 30 seconds. After that a venous phase SCT scan, beginning at the last image position and ending at the upper thoracic aperture, was performed. RESULTS: The mean acquisition time of the SCT scan was 80 seconds (range 70 to 100 seconds), the mean overall procedure time, including image reconstruction, 5 minutes (range, 4 to 6 minutes). 2D images were directly evaluated during CT data acquisition, and 3D image reconstructions within 10 minutes (range, 8 to 11 minutes) after the SCT scan. AAA rupture was assessed in 14/24 patients (58%): in 10/14 patients (71%) rupture was contained to the retroperitoneum, and in 4/14 patients (29%) intraperitoneal rupture was observed. Successful EVAR was performed in 6/14 patients (43%) with ruptured AAA, and in 8/10 patients (80%) without ruptured AAA. Open surgery was exclusively performed in 6/24 patients (25%) with inappropriate anatomy for EVAR and in 4/24 patients (17%) with intraperitoneal rupture. CONCLUSIONS: Spiral computed tomography angiography is a reliable technique to assess feasibility of endovascular aneurysm repair in patients with ruptured aortic aneurysm. However, it can only be recommended for patients with stable hemodynamics, despite of the short acquisition time.

The therapeutical approach to diseases of the descending thoracic and abdominal aorta has dramatically changed over the last decade due to new stent-graft-based endoluminal techniques. In particular elderly patients with a variety of diseases, such as ruptured and asymptomatic aneurysms, acute B-dissections, acute penetrating ulcers, mycotic aneurysms or traumatic aortic injuries will benefit from these minimally invasive alternatives, which can be performed under local anesthesia. As the durability of these devices is not yet proven the patients undergoing endoluminal aortic repair will need life-long clinical and imaging follow-up.

INTRODUCTION: There are conflicting reports on the posttransplantation morbidity and mortality of patients listed urgently and/or supported by a ventricular assist device (VAD). The aim of this study was to analyze the outcomes with regard to pretransplantation condition (elective, urgent, VAD). METHODS: All adult recipients between January 1, 2005, and October 31, 2012, were included. Demographics; preoperative, operative, and postoperative data; outpatient follow-up; and donor characteristics were collected and analyzed. RESULTS: Of a total of 74 patients, 19 were listed urgently, 20 had a Berlin Heart EXCOR BVAD (biventricular assist device) (Berlin Heart, Berlin, Germany) (8 urgent), 7 had a Berlin Heart INCOR left VAD (Berlin Heart, Berlin, Germany) (2 urgent), and 2 had a HeartWare left VAD (HeartWare International, Framingham, Mass, USA) (none urgent). Mean age was 52 ± 12years. The overall 30-day, 1-year, and 3-year survival was 90% ± 3%, 79% ± 5%, and 66% ± 7%. There was no difference in survival when comparing urgently listed (95% ± 5%, 84% ± 8%, 74% ± 12%) and elective patients (89% ± 4%, 77% ± 6%, 63% ± 8%; P = .4), and VAD patients (86% ± 6%, 76% ± 8%, 63% ± 11%) and those without mechanical support (93% ± 4%, 81% ± 6%, 69% ± 9%; P = .6). In-hospital outcomes and long-term complications were also comparable. CONCLUSIONS: Our series suggests that urgent patients and patients on a VAD have a posttransplantation outcome comparable to elective patients and patients without a VAD. These data support the effectiveness of the current practice of listing for heart transplantation.

Temporary asystole induced with adenosine or electrically induced ventricular fibrillation has previously been proposed to prevent hypertension during transluminal placement of thoracic endovascular stent-grafts. Nitroglycerin is a safe and less invasive alternative to control blood pressure and, in contrast to the methods mentioned, can also be used during stent-grafting performed under local anesthesia.

Bleeding after complex ascending aortic, aortic root or transverse arch surgery which is inaccessible or difficult to control may present a major problem. Here, we describe a modified Cabrol-shunt technique using complete mediastinal coverage with decompression into the innominate vein where the classical technique is not suitable. The long-term fate of the classical aortoatrial and modified mediastinal to innominate shunts has been analyzed to assess their potential complications.

BACKGROUND: The saphenous vein is an established conduit for coronary revascularization. Disadvantages of traditional harvest technique are significant pain and morbidity. We compared the endoscopic harvest technique with the traditional method. METHOD: 140 coronary artery bypass graft (CABG) patients were randomized into 2 groups: endoscopic vein harvesting (EVH; n = 80) and traditional open vein harvesting (OVH; n = 60). Analysis included preoperative risk factors for wound complication, harvesting time, graft injury, and intraoperative and postoperative complications. Patient follow-up lasted 3 months. RESULTS: The preoperative risk profiles of the groups were comparable. In the EVH group, 5 patients (7.1 %) had to be switched to the open technique. EVH time was 45 +/- 6.2 min vs. 31.1 +/- 6.5 min. Two patients (2.5 %) had to be revised because of bleeding complication vs. 6 (10 %) in the OVH group. No local infections or wound complications were observed in the EVH group vs. 11 (18 %) cases in the OVH group. Two OVH cases (3.6 %) were readmitted for wound debridement. All EVH patients reported less pain and were completely satisfied by the cosmetic results. CONCLUSION: EVH is a safe and efficient technique for CABG. Morbidity was significantly lower, with reduced pain and better cosmetic results. EVH time was significantly longer compared to the traditional harvesting technique.
