Patchinfekt nach Carotis-TEA. Eine seltene Komplikation. Ein Fall mit fatalen Folgen<br />
Objective: Einleitung: Anhand einer Fallbeschreibung wird die seltene Komplikation des<br />
Patchinfektes nach Carotis-TEA diskutiert.<br />
Methods: Fallbeschreibung<br />
Results: Fallbericht: 3 Jahre nach einer Carotis-TEA mit Dacronpatch-Verschluss tritt bei einer<br />
50-jährigen Patientin ein Eiteraustritt über die Narbe auf. Bei Verdacht auf einen Patchinfekt<br />
erfolgt die Rekonstruktion <strong>der</strong> Bifurkation mittels Veneninterponat. In sämtlichen entnommenen<br />
Proben ist kein Bakterienwachstum nachweisbar. In <strong>der</strong> Folge antibiotische Therapie mit<br />
Ciprofloxacin. 2 Monate später erneute Sekretion aus <strong>der</strong> Narbe. Im Duplex Nachweis eines<br />
Flüssigkeitssaum um das Interponat. Es erfolgt eine antibiotische Therapie mit Vancomycin<br />
für 2 Wochen und Zyvoxid für weitere 4 Wochen. Nach Abschluss <strong>der</strong> Therapie Persistenz <strong>der</strong><br />
ödematösen Verquellung des U mgebungsgewebe und hochgradige Stenose des<br />
Interponates (Duplex/MRI). Rehospitalisation nach einem weiteren Monat mit Kreislaufschock<br />
bei anämisieren<strong>der</strong> GI-Blutung unter OAK. Bei Eintritt Hyposensibilität <strong>der</strong> rechten<br />
Gesichtshälfte. Im Duplex nach Revertierung <strong>der</strong> OAK Nachweis eines thrombotischen<br />
Verschlusses <strong>der</strong> Carotisgabel. Im CT Mediainfarkt. Bei progredientem Hirnödem erfolgte die<br />
Kraniotomie. Die Patientin konnte nach 3 Wochen mit einer Hemiparese links in die Rehab entlassen<br />
werden. Bei erneutem Verdacht auf einen low-grade Infekt Therapieversuch mit<br />
Vancomycin. Bei Ausbleiben einer Besserung <strong>der</strong> Infektwerte Beginn mit einer Steroidtherapie<br />
bei Verdacht auf eine Vasculitis. Unter einer Dosierung mit 50 mg Prednison deutliche<br />
Besserung des Befundes.<br />
Conclusion: Schlussfolgerung:. Der Patchinfekt ist eine seltene Komplikation nach Carotis-<br />
TEA. In <strong>der</strong> Literatur wird die Inzidenz mit unter 1% beschrieben. Das therapeutische Konzept<br />
umfasst das lokale Debridement mit Excision des infizierten Arteriensegmentes und Ersatz<br />
mittels Veneninterponat begleitet von einer Langzeitantibiotikatherapie.<br />

Endovascular treatment of isolated common iliac artery aneurysm using a bifurcated stentgraft:<br />
a potential pitfall<br />
Objective: Endovascular repair of isolated common iliac artery (CIA) aneurysm is feasible<br />
when specific anatomical criteria are met. We describe a potential pitfall of endovascular iliac<br />
artery aneurysm repair.<br />
Methods: A 78-year old man was referred with an incidental finding of a right 9.7cm CIA aneurysm<br />
and a mild dilatation of the abdominal aorta. As the aneurysm had no proximal neck, it<br />
was decided to treat the patient with a bifurcated stent. The aneurysm extended to the right<br />
iliac bifurcation, which necessitated an embolization of the ipsilateral internal iliac artery.<br />
Afterwards the main body of a bifurcated stent was inserted and deployed. After ipsilateral<br />
iliac extension canulation of the contralateral stump was attempted. The gate of the contralateral<br />
limb was at the level of a focal narrowing of the abdominal aorta, not fully deployed.<br />
Canulation from a left contralateral approach was impossible. With a cross-over technique a<br />
guidewire was passed into the left iliac artery. The contralateral limb was inserted, but could<br />
not pass beyond the local narrowing of the distal aorta. Kissing balloon-angioplasty of the<br />
aorta was performed. After this the procedure was uneventful.<br />
Results: Endovascualr treatment of isolated CIA aneurysms is feasible. Various approaches<br />
can be employed, ranging from the use of covered stents placed percutaneously, to the use<br />
of iliac extensions or modular stents. Covered stents and iliac extensions from modular stent<br />
systems can only be used in cases with sufficient proximal and distal neck. In the absence of<br />
a proximal neck, the stent has to be extended into the distal abdominal aorta. When using a<br />
bifurcated stent the absence of a large diameter distal abdominal aorta may cause a failure<br />
of deployment of the contralateral limb to its full diameter, thus hampering the canulation of<br />
the stump. When planning an endovascular procedure, this potential pitfall must be taken into<br />
account. When canulation of the contralateral leg is impossible, endovascular conversion into<br />
an aorto-uni-iliac stent should be consi<strong>der</strong>ed as a bailout procedure, prior to conversion to<br />
open surgery.<br />
Conclusion: Endovascular treatment of an isolated CIA aneurysm using a bifurcated stent<br />
system is feasible. A potential pitfall exists if the distal abdominal aorta is not dilated.<br />

Ruptured aneurysm of the pancreatico-duodenal artery<br />
Objective: Key words: pancreatico-duodenal artery aneurysm, aorto-hepatic bypass Case<br />
Report<br />
Methods: Case report<br />
Results: A 48-year-old female presented to a peripheral hospital with acute epigastric abdominal<br />
pain, nausea and non-bilious emesis. An abdominal ultrasound showed cholecystolithiasis<br />
and signs of appendicitis. The patient un<strong>der</strong>went laparoscopy. 400 ml of blood in abdomine<br />
as well as a pulsating tumour close to the mesenteric root were found. A ruptured aortic<br />
aneurysm was suspected, the intubated patient was transferred to our hospital. Computed<br />
tomography of the abdomen showed a hematoma in the transverse mesocolon and an aneurysm<br />
of the pancreatico-duodenal artery, but no signs of acute bleeding. No signs of pancreatitis<br />
or atherosclerosis were present. An angiography showed the ruptured aneurysm and an<br />
almost complete occlusion of the celiac trunk. Spleen and liver were supplied by retrograde<br />
blood flow from the gastroduodenal artery. An attempt to dilate the celiac trunk failed. The<br />
patient un<strong>der</strong>went laparatomy. An aorto-hepatic bypass was performed, the gastro-duodenal<br />
artery was clipped and a cholecystectomy was carried out. After surgery the patient additio-<br />

nally un<strong>der</strong>went endovascular coiling of the aneurysm. The postoperative course was unremarkable.<br />
No further aneurysms were found.The patient was discharged on the 13th postoperative<br />
day. Six weeks after surgery a duplex sonography showed good perfusion of the<br />
aorto-hepatic bypass. About 3 months after surgery occasional postprandial bloating and<br />
mo<strong>der</strong>ate pain from the scar were the only residues, CT-scan showed no perfusion of the<br />
aneurysm.<br />
Conclusion: Splanchnic aneurysms are infrequently encountered, peripancreatic artery aneurysms<br />
are highly unusual. Risk factors include a history of frequent pancreatitis episodes, and<br />
atherosclerosis. Absence of the celiac axis complicates treatment. Often the clinical presentation<br />
of a splanchnic aneurysm is dramatic. Yet, it is of importance to assess the patency of the<br />
celiac axis as well, to prevent infarction. Elective procedures include an open vascular<br />
approach and/or endovascular intervention. Associated aneurysms are common and ought<br />
to be excluded.<br />

Interne Qualitätskontrolle Karotischirurgie 2002 bis 2005<br />
Objective: Seit 2002 werden am Kantonsspital St.Gallen Operationen an <strong>der</strong> Karotis immer in<br />
Intubationsnarkose und unter zerebraler Durchblutungskontrolle mittels intraoperativem SEP-<br />
Neuromonitoring (somatosensorisch evozierte Potentiale nach Medianusstimulation) durchgeführt.<br />
Wir erstellen seitdem jährlich einen Qualitätsbericht und vergleichen unsere Daten<br />
mit jenen <strong>der</strong> deutschen Gesellschaft für Gefässchirurgie DGG. Diese Daten erlauben<br />
Rückschlüsse auf die Qualität und ermöglichen Verbesserungsmassnahmen <strong>der</strong> operativen<br />
Versorgung. Nach dem Bericht 2004 wurde insbeson<strong>der</strong>e die Durchführung des intraoperativen<br />
Neuromonitorings sowie einer intraoperativen Kontrollangiografie bei allen Patienten<br />
gefor<strong>der</strong>t.<br />
Methods: Erfassung aller zwischen 2002 und 2005 an <strong>der</strong> Karotis operierten Patienten. Alle<br />
Patienten wurden präoperativ stadienunabhängig mittels Duplexsonografie und MR-<br />
Angiografie (selten CT-Angiografie) abgeklärt. Erfasst werden neben intraoperativen Daten<br />
zur Operationstechnik auch die postoperativen Komplikationen.<br />
Results: Zwischen 2002 und 2005 wurden 376 Patienten (2005: 107 Patienten) an einer<br />
Karotisstenose operiert. Operationstechnik: Konventionelle-TEA 368/104, Eversions-TEA 8/3,<br />
Patchplastik 362/98, Interponate 5/1, passagere Shunteinlage 140/25, Neuromonitoring<br />
286/102, intraoperative Angiografie 91/3<strong>4.</strong> Komplikationen: 3/0 schwere und 8/1 leichte<br />
neurologisch-ischämische Defizite, davon 6/1 passager, 5/0 permanent.<br />
Hirnnervenläsionen 33/6, revisionsbedürftige Nachblutung 20/<strong>4.</strong><br />
Conclusion: Wie im Vorjahresbericht gefor<strong>der</strong>t, konnte das intraoperative Neuromonitoring in<br />
95% <strong>der</strong> Fälle (Vorjahr 72%) durchgeführt werden. Diese Steigerung war insbeson<strong>der</strong>e durch<br />
die Aufstockung <strong>der</strong> personellen Ressourcen möglich. Somit konnten wir uns unserem Ziel<br />
von 100% deutlich annähern. Im Vergleich zum Vorjahr erreichten wir darunter eine weitere<br />
Senkung <strong>der</strong> neurologisch-ischämischen Komplikationen auf 1% (Vorjahr 5%). Das Auftreten<br />
<strong>der</strong> postoperativen revisionsbedürftigen Nachblutungen 3.5% und Hirnnervenläsionen 5%<br />
blieb im Vergleich zum Vorjahr konstant. Eine intraoperative Kontrollangiografie erfolgte in<br />
32% (Vorjahr 51%).<br />

Contained rupture of an infrarenal aortic aneurysm into the vertebral body<br />
Objective: Patients with a ruptured aortic aneurysm present usually with back-pain and signs<br />
of shock. Contained rupture of a true aortic aneurysm which presents as a false aneurysm<br />
sealed by the vertebral body is rareley seen and also classified as a chronic contained rupture.<br />
Methods: Case report: a 86-year-old man was admitted to the hospital with a several week<br />
history of lumbar back pain. There was marked progression of his pain in the last few days<br />
before admission so that the patient could hardly walk. Abdominal examination showed a<br />
pulsatile mass. The patient was haemodynamically stable. Laboratory findings showed an<br />
impaired renal function and an INR of 5.5. The patient was anticoagulated because of atrial<br />
fibrillation. A computed tomography revealed an 8cm abdominal aortic aneurysm and erosion<br />
of the adjacent L3 and L4 vertebrae.<br />
Results: The anticoagulation was reversed with concentrated coagulation factors<br />
(ProthromblexR) and the patient was operated on the day of admission. We decided to perform<br />
an open operation because of a marked kinking of the proximal neck. After opening the<br />
aneurysm there was a 2cm-circular defect of the back-wall of the aneurysm-sac with thrombus<br />
in the cavity of the eroded vertebral bodies representing a chronic sealed rupture into the<br />
vetebral body or a pseudoaneurysm. The aneurysm was repaired with a PTFE tube-graft. The<br />
operation was uneventful and straight forward. The postoperative course was complicated by<br />
pulmonary problems due to a known paresis of the right recurrent laryngeal nerve and swolling<br />
problems as a result of a former cerebrovascular event.<br />
Conclusion: Erosion of the vetebral body through pressure caused by the pulsating aneurysm<br />
sac is a rare but known manifestation of an aneurysm. A chronic contained rupture of an<br />
aneurysm into such an erosion representing a pseudoaneurysm of the aneurysms is even<br />
more rarely seen.<br />
