Caution: Air Embolism Related to Heli-Fx EndoAnchor System in Zone 2 Thoracic Aneurysm Repair

Purpose We report a case of significant air embolization to the ascending aorta immediately following deployment of EndoAnchors in the aortic arch during a procedure to correct a type 1A endoleak. Case report The novel Heli-Fx EndoAnchor system (Medtronic Vascular, Santa Rosa, CA, USA) was used to deploy helical anchors in the distal aortic arch during a procedure to correct a type 1A endoleak following Zone 2 thoracic endovascular aortic repair of a saccular proximal descending thoracic aorta aneurysm (DTAA). The patient developed ST-segment elevations principally in the inferior leads and severe hypotension moments after EndoAnchor deployment at the proximal edge of the endograft. Transesophageal echocardiogram revealed severe right ventricular hypokinesis and a large amount of air in the ascending aorta. Subsequent management and clinical and radiological 30-day follow-up is presented in addition to a review of the literature and ex vivo testing with the Heli-Fx system to examine potential causes and solutions. Conclusion Precautions, such as pressurized saline infusion to the side port of guiding sheath, should be used whenever manipulating catheters and sheaths such as the EndoAnchor system in the aortic arch to prevent this potentially lethal complication.

A rare presentation of aorto-bronchial fistula and the relevance of open repair in endovascular era

Aorto-bronchial fistula is a rare but potentially fatal condition due to torrential bleeding from erosion of aneurysmal wall into bronchial wall or lung parenchyma. It is usually associated with infection, lung transplantation, pulmonary malignancies, atherosclerotic and mycotic aneurysms, and anastomotic pseudoaneurysms after open or endovascular surgery. The typical presentation usually manifested by haemoptysis, but rarely the patient also can be presented with hematemesis and this will delay the definitive treatment. Surgical or endovascular repair is mandatory because non-operative management will lead to a poor prognosis due to massive bleeding from the fistula. We would like to present a unique case of an elderly man presented with intermittent haematemesis, in which he later developed profound haemoptysis and diagnosed with ABF. Although in the era of endovascular, the ABF was successfully treated via open thoracotomy, resection of thoracic aorta aneurysm, left lower lobe lobectomy, and completed with aortic repair using Gelweave aortic graft.

P6500Genetics links abdominal and thoracic aorta aneurysm

Introduction Familial disease, with a genetic cause, occurs in at least 20–30% of the families of patients with an aortic aneurysm. In these families there is an increased risk for relatives. Therefor family screening is recommended around the age of 50–60 years for first degree relatives of patients with an abdominal aneurysm (AAA) and relatives of patients with thoracic aorta aneurysms (TAA). However current guidelines do not specify the extend of aorta screening for relatives of patients with AAA and patients with TAA. Current practice is that first degree relatives of AAA patients are offered abdominal echo screening for AAA and relatives of TAA patients cardiologic echo for TAAA. Although co- occurrence of AAA with TAAA in rare genetic disease is well known, for other familial aneurysm disease, the frequency of the co-occurrence of AAA and TAAA has not been established. Purpose To improve family screening for familial aneurysm, and identify the role of underlying genetic defects. Methods To determine the genetics of AAA, whole exome sequencing and CT family screening of the complete aorta was performed in 391 families with familial aneurysm. These families are nested in a patient cohort ascertained form unselected consecutively diagnosed AAA patients visiting the Vascular Surgery Clinic at the our MC. Results In 391 families, 360 relatives had a dilated aorta. The spectrum of aortic features in the relatives included 210 (58%) relatives with AAA, 102 (28%) relatives with TAA. Co-occurrence of AAA and TAA was noted in 41 (11%) relatives. In addition 66 (18%) and 79 (22%) had a dilation in the arteria iliaca communis sinistra resp. dextra. In 18 families pathogenic mutations in 11 aneurysm genes were detected. Conclusion To reduce underdiagnoses of relatives of AAA patients, CT screening of the total aorta and the iliac arteries is the method of choice, and should replace echo screening of specific parts of the aorta in relatives. Updating the guidelines for family screening for aortic aneurysms is needed to improve early detection and treatment of family members with aorta dilatations.

The chest pain in neurological practice. Non deesset...

Chest pain can be a “mask” of a life-threatening condition, which the practitioner must remember. One of such life-threatening condition is aortic aneurysm, which diagnosis presents significant difficulties in routine clinical practice. Clinical manifestations of thoracic aortic aneurysms are extremely variable and non-specific and are mainly depends on the size of the aneurysmal sac, its localization and extent, as well as the etiology of the disease. Here we present a clinical case report of a 48 y.o. patient who died because of the acute cardiac tamponade as a complication of dissecting thoracic aorta aneurysm. The lack of symptoms and clinical instrumental data, initially suggesting the presence of life-threatening disease did not allow the physician to suspect aortic aneurysm and urgently take action regarding it.

Thoracic aorta aneurysm- a rare cause of chronic backache with mediastinal shadow: case report

<p class="abstract">Thoracic aortic aneurysms (TAA) are rarely symptomatic. A 55 year old male presents with longstanding chronic backache. CXR showed left hilar shadow with collapse of left lung. Considering the CXR findings and with the patient being chronic smoker a strong possibility of carcinoma lung with bony metastasis was kept and further CECT chest was done. The CECT chest was suggestive of a thoracic aorta aneurysm with thrombosis compressing left principal bronchus and its lower lobar branch resulting in distal area of collapse and consolidation of left lower lobe. These findings were further confirmed on CT angiography. The patient was thus diagnosed as a case of descending thoracic aorta aneurysm probably of atherosclerotic etiology with thrombosis. Patient was started on beta blockers and ACE inhibitors along with supportive and symptomatic treatment and was further transferred to the department of CTVS for surgical intervention. Thus, this case report here signifies that possibility of thoracic aorta aneurysm should always be considered in a patient with chronic backache specially in presence of mediastinal shadow on CXR.</p>
