1/169. 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.

2/169. Aorto--bronchial fistula resulting from an accidental fall one year earlier.

    A 75-year-old woman presented with massive haemoptysis 12 months after tripping over her shopping trolley. CT scanning and transoesophageal echocardiography demonstrated a traumatic false aneurysm which was confirmed at surgery to be partially ruptured. Aortobronchial fistula is an unusual cause of massive haemoptysis. It should be considered particularly in patients known to have abnormalities of the thoracic aorta.

3/169. A rare complication of renal biopsy in a child with membranoproliferative glomerulonephritis.

    Percutaneous renal biopsy is essential for the definitive diagnosis of chronic glomerulonephritis. Large arteriovenous fistula (AVF) which is a rare complication of native renal biopsy is generally diagnosed in the first weeks after the procedure. We present a childhood membranoproliferative glomerulonephritis case with an enormous AVF presenting with severe hypertension 15 months after the biopsy that was successfully embolized. In conclusion, AVF must be considered in children having chronic glomerulonephritides even if hypertension appears late after the renal biopsy.

4/169. Successful surgical treatment of aortogastric fistula after an esophagectomy and subsequent endovascular graft placement: report of a case.

    An aortogastric fistula is a rare but fatal complication after an esophagectomy and intrathoracic esophagogastric anastomosis. A 54-year-old man underwent an esophageal resection due to carcinoma in his lower esophagus. The alimentary tract continuity was restored by intrathoracic esophagogastric anastomosis. Forty-six days later, he suffered a massive hematemesis due to an aortogastric fistula which had formed at the esophagogastric suture line. The fistula was surgically obliterated twice, but each operation was followed by pseudoaneurysm formation. The patient was finally successfully treated with an endovascular stent graft placement. This is the first report of a patient surviving after developing this complication.

5/169. Pseudoaneurysm of the superior mesenteric artery with an arteriovenous fistula after simultaneous kidney-pancreas transplantation.

    Vascular complications remain a significant source of morbidity after pancreatic transplantation. We describe a pseudoaneurysm of the superior mesenteric artery (SMA) with an arteriovenous fistula (AVF) involving the SMA and the superior mesenteric vein (SMV) discovered and treated surgically in the second week after kidney pancreas transplantation. The patient experienced pain over the graft, and subsequent radionuclide and Doppler ultrasound scan were suggestive of a pseudoaneurysm in the head of the pancreas. Awaiting confirmatory angiography, the patient became hypotensive and after resuscitation, underwent emergency surgery when a pseudoaneurysm was found in the head of the pancreas. After looping the proximal and distal recipient iliac artery and base of the donor Y vascular graft, the AVF was separated and ligated. The SMV was dissected off the pancreatic head and repaired over a tamponading intraluminal Foley catheter. Graft function was preserved. Based on this experience, an AVF with or without a pseudoaneurysm in the pancreas allograft should be corrected as soon it is suspected.

6/169. Management of aortobronchial fistula with an aortic stent-graft.

    Aortobronchial fistula presenting as massive hemoptysis is a rapidly fatal process that is extremely difficult to manage. We report a case in which endovascular occlusion of a fistula between a thoracic aortic pseudoaneurysm and lung was successfully managed by placement of an aortic endovascular stent-graft. Stent-grafting is a promising technique in managing complications of thoracic aneurysms and grafts.

7/169. Left internal mammary artery to innominate vein fistula complicating pacemaker insertion. Treatment with endovascular transarterial coil embolization.

    arteriovenous fistula (AVF) is rarely encountered as a complication of pacemaker insertion. Percutaneous angiographic therapy of such iatrogenic fistulas can be both safe and effective, leading to important reductions in costs. A 60-year-old woman was admitted to the hospital four weeks after left subclavian pacemaker insertion complaining of signs of congestive heart failure. A loud continuous machinery bruit was heard over the left upper chest. An arteriogram revealed a false aneurysm from the LIMA, 6 mm in-diameter, with formation of an AVF between the LIMA and the left innominate vein. Embolization of the LIMA was carried out using seven platinum coils at the level of the AVF and the false aneurysm was embolized with 3 controlled-release IDC coils. The complete occlusion of the fistula was achieved and the distal LIMA persisted patent due to the opening of collateral vessels from the intercostal arteries. AVF between the subclavian artery or its branches and the subclavian or innominate veins have been reported to be congenital, traumatic and iatrogenic (associated to central venous access to hemodynamic monitoring, dialysis, and very infrequently to pacemaker insertion) but the internal mammary arteries are only rarely involved. The course of AVF is undefined, but generally, surgical or percutaneous embolization is warranted because of the potential appearance of a great number of complications. Surgical repair is associated with significant morbidity and mortality. Whenever possible, percutaneous nonsurgical occlusion of the AVF with coil embolization is the procedure of choice, because of its high success rate and low morbidity.

8/169. Endovascular treatment of arteriovenous fistulas complicating percutaneous renal biopsy in three paediatric cases.

    DESIGN: We evaluated the incidence and history of arteriovenous fistula (AVF) after kidney biopsy and assessed the use of superselective embolization for treatment. OBSERVATIONS: During the last 10 years, 896 kidney biopsies (age range of the patients: 1 month-18.6 years) have been performed in our institution under real-time ultrasonographic guidance with a 14 gauge cutting biopsy needle, and 32 of the patients had renal allografts (3.4%). We observed three cases of AVF (two in allograft kidneys, one in a native kidney) among all biopsies (0.34%), and the incidence of developing AVF after renal allograft biopsy was 6.3%. All three patients with AVF were symptomatic, and intravascular therapy was indicated. INTERVENTIONS: An angiographic study combined with endovascular treatment of the intrarenal AVF and pseudoaneurysm was performed in all three patients. Embolization was performed with bucrylate and lipiodol in two patients and with micro-coils in one. After successful embolization, all three patients became asymptomatic (in two renal bleeding stopped, in one patient with severe uncontrollable hypertension blood pressure returned to normal limits). No complications were observed secondary to the embolization procedure. CONCLUSION: The technique of superselective embolization using a coaxial catheter is an effective and safe method in the treatment of post-biopsy AVFs and pseudoaneurysm.

9/169. Combined resection of the thoracic esophagus and thoracic descending aorta.

    We conducted combined resection of the thoracic esophagus and thoracic descending aorta in 2 patients, one with advanced esophageal cancer with aortic invasion and the other aortoesophageal fistula caused by a false aortic aneurysm. Combined resection of esophageal tumor and adjacent involved organs was conducted in 14 patients with A3:T4 esophageal cancer but none survived 3 years and resecting tumor-invaded organs did not improve patient survival. One major problem of combined resection of the esophagus and aorta is contamination of the posterior mediastinum. In 1 patient, 2-stage surgery for the esophagus and in situ aortic replacement was conducted to reduce operative risk and avoiding infection of the prosthetic vascular graft. With thoracic descending aortic aneurysm adjacent to the esophagus on the increase, cardiovascular surgeons should prepared to undertake combined resection of both the aorta and esophagus.

10/169. Peripheral arterial involvement in neurofibromatosis type 1--a case report.

    Neurofibromatosis is a dominantly inherited, progressive, generalized dysplasia of mesodermal and neuroectodermal tissues. Vascular lesions associated with neurofibromatosis type 1 (NF-1) are mainly characterized by stenosis, occlusion, aneurysm, pseudoaneurysm, and rupture or fistula formation of small, medium, and large-sized arteries. The authors hereby present a rare case of NF-1 with bilateral aneurysms and large pseudoaneurysms of the femoral and popliteal arteries and occlusion of the left superficial femoral artery.
