1/33. Haemosuccus pancreaticus: a clinical challenge.

    BACKGROUND: Haemosuccus pancreaticus is a rare complication of pancreatitis. It is a diagnostic problem for even the most astute clinician and a challenge for the expert endoscopist. We report a 25-year-old male patient who had all the features usually seen in haemosuccus pancreaticus patients: recurrent obscure upper gastrointestinal bleeding, pancreatitis, pseudocyst formation, ductal disruption, fistula and pancreatic ascites. The patient was treated by subtotal pancreatectomy, splenectomy and drainage of the pseudocyst. Although pancreatic duct communication with the surrounding vasculature could not be ascertained, we strongly believe the patient had haemosuccus pancreaticus because, over a follow-up period of 3 years, the patient was not only ascites free, but did not experience any further upper gastrointestinal bleeding. We believe that in evaluating patients with recurrent obscure gastrointestinal bleeding, one should always remember that the pancreas is a part of the gastrointestinal tract and, like other organs, is prone to blood loss.

2/33. Pseudoaneurysm of the abdominal aorta: evaluation with virtual angioscopy of spiral-CT data sets.

    We describe a case of graft-related pseudoaneurysm of the abdominal aorta evaluated with spiral CT and DSA. Spiral CT data sets were processed to obtain surface-rendered internal views (virtual angioscopy, VA) of the graft and the pseudoaneurysm, and to demonstrate from inside the lumen the site of dehiscence. A jet flow phenomenon inside the pseudoaneurysm was observed at DSA. Spiral-CT axial images, multiplanar volume reconstructions with maximum intensity projections, and shaded surface display showed the site of rupture. The VA findings were: (a) from inside the graft lumen, the evidence of a communication canal between the graft and the pseudoaneurysm; and (b) from inside the pseudoaneurysm, the presence of a jet flow. The VA findings showed good correlation with those obtained with the other imaging techniques.

3/33. Transesophageal echocardiographic identification of an abdominal aortic pseudoaneurysm complemented by a transpulmonary echo contrast agent.

    Pseudoaneurysm of the abdominal aorta, a rare complication after traumatic injuries, represents a diagnostic challenge for which sophisticated imaging modalities are often used for its early identification. We describe a case in which transesophageal echocardiographic examination complemented by a transpulmonary echo contrast agent was useful not only in demonstrating the pseudoaneurysm, but in helping to localize the intravascular communication between the aorta and the pseudoaneurysm.

4/33. Left ventricular pseudoaneurysm complicating infective pericarditis.

    Cross sectional echocardiography demonstrated a pseudoaneurysm of the left ventricular posterolateral wall close to the atrioventricular junction in a 4 year old girl with infective pericarditis complicating lobar pneumonia. Colour flow Doppler demonstrated bidirectional flow across the communication hole. Surgical resection was successful.

5/33. Inguinal mass as a late complication of hip arthroplasty. Differential diagnosis and treatment from a vascular surgical perspective.

    We report on three patients with a symptomatic inguinal mass as a late complication of repetitive arthroplastic hip surgery. In one case, there was a false aneurysm and in two cases a so-called "synovial cyst". A synovial cyst is usually an enlarged iliopsoas bursa in communication with the capsule of the hip joint. Hypersecretion in arthritic joints may cause expansion of this bursa. Compression of the common femoral and external iliac veins may lead to outflow obstruction and leg swelling. The most important diagnostic tools are plain films of the hip joint and ultrasound of the groin including colour-coded assessment of the femoral vessels. Symptomatic cysts usually need removing by an anterior approach. Loose arthroplastic components can be causative and should be replaced.

6/33. Late development of aortic pseudoaneurysm after coarctation repair with fistulization to the bronchial tree. A case report.

    BACKGROUND: Fistulous communication between the aorta and the tracheobronchial tree is an uncommon and serious cause of hemoptysis secondary to complications of a previous operation performed on the aorta. In cases in which an appropriate surgical intervention is carried out, the survival rate approaches 76%. This surgery is considered one of the most risky operations on the aorta, challenging the surgeon's ability to resolve the problem. methods: We present the case report of a 43-year-old female with massive hemoptysis. Her medical history disclosed repair of coarctation of the aorta (15 years before). She underwent emergency left thoracotomy; surgical exploration revealed a false aneurysm from the previous aortic patch repair which communicated to a subsegmental bronchus of the left upper lobe. RESULTS: The thoracic aorta was isolated and clamped, and the previous patch was removed. The bronchial side of the fistula was managed with left superior lobectomy and the aorta was repaired with the placement of a coated woven dacron graft onto healthy aortic tissue. CONCLUSIONS: The patient had an uneventful recovery and remains asymptomatic six months after discharge.

7/33. fistula between a saphenous vein graft aneurysm and the pulmonary artery trunk.

    We report the case of a 52-year-old man who was admitted for atypical thoracic pain 18 years after a saphenous vein bypass graft of the left anterior descending coronary artery. Investigations demonstrated an aneurysm of the middle portion of the vein graft with a fistulous communication to the pulmonary artery trunk. The aneurysm was excised surgically, and the fistula was closed with an autogenous pericardial patch.

8/33. Surgical repair of a pseudoaneurysm of the ascending aorta after aortic valve replacement.

    We report the case of a patient with a pseudoaneurysm of the ascending aortic clinically diagnosed 5 months after surgical replacement of the aortic valve. diagnosis was confirmed with the aid of two-dimensional echocardiography and helicoidal angiotomography. The corrective surgery, which consisted of a reinforced suture of the communication with the ascending aorta after opening and aspiration of the cavity of the pseudoaneurysm, was successfully performed through a complete sternotomy using extracorporeal circulation, femorofemoral cannulation, and moderate hypothermia, with no aortic clamping.

9/33. Aortic root replacement and coronary interposition using a cryopreserved allograft and its branch.

    This communication describes a modified aortic root replacement technique using a cryopreserved allograft consisting of the aortic conduit and its branch. This method was applied in a patient suffering from infective pseudoaneurysm which had developed after aortic root replacement using an artificial graft with a mechanical aortic valve. A piece of the innominate artery obtained from the aortic allograft was used for interposition between the fragile left coronary artery root and the main conduit of the allograft.

10/33. Giant pseudoaneurysm of the right ventricular outflow tract after repair of truncus arteriosus: evaluation by MR imaging and surgical approach.

    One year after surgical repair of the truncus arteriosus, a 1-year 8-month-old boy was found to have a pseudoaneurysm of the right ventricular outflow tract (RVOT). Cine-magnetic resonance imaging (MRI) showed a narrow communication between the RVOT and aneurysm. MRI was useful to evaluate the anatomical and spatial relations between the pseudoaneurysm and the surrounding structures, therefore an appropriate approach was chosen. Thus, a median sternotomy approach was carried out and ordinary central cannulation was feasible to establish a cardiopulmonary bypass. The defect was successfully repaired with reconstruction using a monocuspid outflow patch. MRI provided useful information for deciding the surgical approach.
