[Intra-abdominal vascular injuries after blunt abdominal trauma]. / Intraabdominelle Gefäßverletzungen nach stumpfem Bauchtrauma.

Vascular injuries and hemorrhaging are serious potential complications in the management of patients with blunt abdominal trauma. The treatment depends on the extent and localization and can range from surveillance to endovascular treatment up to open surgery. The keys to success include the focused assessment with sonography for trauma (FAST) management and timely decision making. Abdominal vascular trauma continues to be a difficult problem and open and endovascular techniques continue to evolve in order to address this complex disease process.

[Results of a single center vascular screening program in Germany]. / Ergebnisse eines monozentrischen Gefäßscreeningprogramms in Deutschland.

BACKGROUND: Cardiovascular diseases are the main cause of death in Europe with a relevant socioeconomic burden. A screening program for vascular diseases in asymptomatic persons with a defined risk constellation can lead to an early diagnosis. OBJECTIVE: The study examined a screening program for carotid stenosis, peripheral arterial occlusive disease (PAOD) and abdominal aortic aneurysms (AAA) in persons without any known vascular disease with respect to demographic data, risk factors, pre-existing conditions, medication intake, detection of pathological findings and/or findings requiring treatment. MATERIAL AND METHODS: Test subjects were invited using various information material and filled in a questionnaire on cardiovascular risk factors. The screening took place with measurement of the ABI and duplex sonography as a monocentric prospective single arm study within 1 year. Endpoints were the prevalence of risk factors and pathological and/or results requiring treatment. RESULTS: A total of 391 persons participated, 36% presented with at least 1 cardiovascular risk factor, 35.5% with 2 and 14.4% with 3 or more. The sonography showed results requiring control with a carotid stenosis of < 50-> 75% or occlusion in 9%. An AAA with a diameter of 3.0-4.5 cm was diagnosed in 0.9% and a pathological ABI < 0.9 or > 1.3 in 12.3%. The indications for a pharmacotherapy were found in 17% and no operation was recommended. CONCLUSION: The practicability of a screening program for carotid stenosis, PAOD and AAA of a defined risk population was shown. Vascular pathologies that required treatment were hardly found in the catchment area of the hospital. Consequently, the implementation of this screening program in Germany based on the collected data cannot currently be recommended in this form.

[Deep vein thrombosis as a primary symptom of abdominal aortic aneurysm : Bilateral deep vein thrombosis caused by infrarenal abdominal aortic aneurysm (15 cm in diameter) with complete compression of the inferior vena cava]. / Tiefe Venenthrombose als Primärsymptom eines abdominellen Aortenaneurysmas : Beidseitige 4-Etagen-TVT durch infrarenales Bauchaortenaneurysma (15 cm Durchmesser) mit vollständiger Kompression der V. cava inferior.

This article presents the case of a 70-year-old obese patient with severe bilateral leg pain due to deep vein thrombosis. After unsuccessful venous recanalization, computed tomography angiography revealed an abdominal aortic aneurysm 15 cm in diameter with total compression of the inferior vena cava. For venous decompression as well as rupture prophylaxis, conventional open surgical repair was performed.

The first case of traumatic internal carotid arterial dissection? Verneuil's case report from 1872.

Dissecting aneurysms of the internal carotid artery were considered as very rare disorders before the seventies. Undiagnosed carotid-artery dissections, however, may have gone hidden behind earlier reports of delayed "apoplexy" due to "traumatic carotid thrombosis". Here, we present a case report of delayed stroke after trauma, published by Aristide Verneuil in 1872 in the Bulletin de l'Académie de Médecine and cited under the heading of vascular rupture and dissecting aneurysm by Heinrich Quincke in 1876. Verneuil's case report represents, to our knowledge, the first detailed clinical description of a patient with a traumatic carotid dissection confirmed at autopsy. The author highlighted the diagnostic challenges of this case, head injury followed by delayed hemiplegia suggesting an intracranial bleeding.

Clinical significance of perioperative changes in ankle-brachial index with regard to extremity-related outcome in non-diabetic patients with critical limb ischemia.

PURPOSE: To evaluate the significance of perioperative changes in ankle-brachial index (ABI) with regard to extremity-related outcome in non-diabetic patients with critical limb ischemia (CLI) following revascularization. METHODS: The study represents a subanalysis of the multicentric Registry of First-line Treatment in Patients with CLI (CRITISCH). After exclusion of diabetic patients, conservative cases, and primary major amputation, 563 of 1200 CRITISCH patients (mean age 74 ± 10.7 years) were analyzed. This population was divided into two groups regarding perioperative ABI changes ∆ + 0.15 (Group 1) or ∆ - 0.15 (Group 2). Study endpoints were reintervention and major amputation during a mean follow-up of 14.6 ± 9 months. Logistic regression was performed in order to identify factors for ABI group affiliation. RESULTS: There were 279 patients in Group 1 (49.5%) and 284 in Group 2 (51.5%). ABI sensitivity and specificity regarding vessel patency were calculated to be 54 and 87%. A preoperative ABI ≤ 0.4 [odds ratio (OR) 7.7], patent vessels at discharge (OR 12.2), and secondary interventions (OR 2.4) were identified as factors for Group 1 affiliation. Contrariwise, previous revascularization (OR 0.6), a glomerular filtration rate ≤ 15 ml/min/1.73 m2 (OR 0.3), and TASC A lesions (OR 0.2) were associated with Group 2 affiliation. No statistical difference was found with regard to the need of reintervention. However, time to reintervention was significantly shorter in Group 2 compared to that in Group 1 (10.0 ± 9.5 months vs 12.1 ± 9.1 months; p = 0.005). Amputation rate in Group 2 was 14.4%, significantly higher compared to that in Group 1 (6.0%; p < 0.0001). CONCLUSIONS: Failure of perioperative ABI improvement is associated with a higher probability for amputation and should be valued as prognostic factor in non-diabetic patients with CLI. Patients with no/marginal improvement in ABI after revascularization require close follow-up monitoring and may benefit from early reintervention.

Endovascular treatment of genetically linked aortic diseases.

BACKGROUND: The most important structural proteins of the vascular wall are collagen and elastin. Genetically linked connective tissue diseases lead to degeneration, aneurysm formation and spontaneous dissection or rupture of arteries. The most well-known are Marfan syndrome, vascular Ehlers-Danlos syndrome (type IV), Loeys-Dietz syndrome and familial aortic aneurysms and dissections. OBJECTIVE: This review article addresses the current status of endovascular treatment options for important connective tissue diseases. MATERIAL AND METHODS: Evaluation of currently available randomized studies and registry data. RESULTS: The treatment of choice for patients that are mostly affected at a young age is primarily conservative or open repair. There is only limited evidence for endovascular aortic repair (EVAR) of abdominal aneurysms or thoracic endovascular aortic repair (TEVAR). CONCLUSION: The progression of the disease with dilatation leads to secondary endoleaks and high reintervention rates with uncertain long-term results. For this reason, there is currently consensus that EVAR and TEVAR should be limited to justified exceptional cases and emergency situations in patients with genetically linked aortic diseases.

[Prevention of aortic erosion by a bone cement skid : Thoracic endovascular aortic repair following kyphoplasty]. / Pelottierung der A. thoracica descendens durch einen Zementsporn : Endovaskuläre Behandlung nach Kyphoplastie.

The underlying case report describes the successful endovascular prevention of an aortic injury by a bone cement skid after kyphoplasty. The intervention was performed in order to prohibit fatal aortic rupture or embolisation and underlines the role of vascular surgery techniques in interdisciplinary clinical networks.

Challenging access in endovascular repair of infrarenal aortic aneurysms.

Endovascular repair has revolutionized the treatment of infrarenal aortic aneurysms. However, its application is still limited in patients with challenging access conditions such as small-caliber vessels, iliac tortuosity, excessive calcification or occlusive disease. The underlying manuscript addresses the crucial role of preoperative access vessel evaluation and summarizes recent developments in endograft manufacturing and surgical techniques allowing for coping with hostile access conditions. Furthermore, alternative access routes and complication management are discussed.
