Pancreaticoduodenectomy for trauma: delayed reconstruction: a case report

Experience and success with packing, resuscitation, and re-exploration for severe traumatic liver injury stimulated application of this concept to more complicated problems. In the case presented, these principles were utilized in managing a combined major hepatic and pancreaticoduodenal disruption. We emphasize stabilization, temporization, and delayed reconstruction.     

Ligation of symptomatic celiac artery aneurysm without vascular reconstruction: Utilizing the natural collateral circulation of the celiac axis: A case report

IntroductionCeliac artery aneurysm is very rare visceral artery aneurysm. Symptomatic and ≥ 2.5 cm sized aneurysm requires treatment. Excision and revascularization is the most commonly employed procedure.Case presentationWe report a case of ligation and excision of celiac artery aneurysm extending onto the splenic and hepatic arteries without vascular reconstruction. The patient was a 52 year old lady who was evaluated for abdominal pain and was found to have a celiac artery aneurysm involving the hepatic and splenic arteries. She was evaluated with computerized tomography and digital subtraction angiography of the abdominal vessels. These confirmed good natural collaterals from the branches of superior mesenteric artery supplying the liver, stomach and spleen. We performed ligation and excision of the aneurysm and ligation and division of hepatic, splenic and left gastric arteries as the aneurysm was extending on to these vessels, without any vascular reconstruction, utilizing the natural collaterals from the superior mesenteric artery.DiscussionLigation of celiac artery aneurysm without revascularization is often done in emergency situations. Excision and revascularization is the treatment of choice to ensure adequate blood supply to liver, spleen and stomach. We could utilize the natural collateral circulation of celiac artery from superior mesenteric artery avoiding a complex procedure of revascularization.ConclusionWe present this because of the rarity of the disease as well as rarity of the technique of not performing vascular reconstruction. We emphasize on the pre-operative and operative evaluation of collateral circulation with conventional angiography and intraoperative Doppler respectively.     

Medullary streaks in a patient with atherosclerotic internal carotid artery occlusion: case report

BACKGROUND: Magnetic resonance imaging (MRI) of a patient with atherosclerotic internal carotid artery (ICA) occlusion demonstrated medullary streaks in the deep white matter, which were previously observed only in moyamoya disease and may indicate decreased cerebral blood flow. Cerebral perfusion and metabolism were evaluated using positron emission tomography (PET). CASE DESCRIPTION: A 46-year-old man presented with right hemiparesis and motor aphasia. Cerebral angiography showed left cervical ICA occlusion. MRI showed medullary streaks in the deep white matter of the left middle cerebral artery (MCA) territory. PET imaging of this region revealed decreased cerebral blood flow and increased oxygen extraction fraction and cerebral blood volume. MRI after superficial temporal artery-MCA anastomosis revealed decreased intensity of the medullary streaks. CONCLUSIONS: Medullary streaks in patients with atherosclerotic ICA occlusion may indicate reduced perfusion pressure and increased risk of recurrent stroke.     

Acute basilar artery occlusion in a patient with left subclavian artery occlusion due to first rib anomaly: case report

A previously healthy 22-year-old man presented with thoracic outlet syndrome manifesting as Raynaud's phenomenon in the left hand and embolic occlusion of the basilar artery. Three-dimensional computed tomography angiography showed that the left subclavian artery was occluded as it passed over the abnormal first rib. Retrograde propagation of the thrombus from the site of arterial occlusion and/or reflux of embolic material was suspected. Medical therapy was started. The patient underwent resection of the anomalous rib. Postoperative angiography demonstrated that the subclavian artery was recanalized with almost normal distal flow. The basilar artery was also recanalized. Thoracic outlet syndrome due to a first rib anomaly may cause stroke.

Internal carotid artery stenosis and external carotid artery occlusion with unusual extracranial collateral pathway: case report

A patient with stenosis of the internal carotid artery and occlusion of the external carotid artery associated with an unusual extracranial collateral pathway is presented. A 63-year-old man was hospitalized for sudden onset of black-out after urination. He was alert, and no neurological deficit was found. MRI showed multiple lacunae in the bilateral putamens. Cerebral angiogram demonstrated severe stenosis of the left internal carotid artery at its cervical segment and complete occlusion of the left external carotid artery at its origin. The ascending pharyngeal artery originated from the left internal carotid artery above its stenotic lesion and the superior thyroid artery originated from the left common carotid artery. The sternocleidomastoid branch from the left superior thyroid artery and the muscular branch from the left vertebral artery anastomosed with the muscular branch of the ascending pharyngeal artery. The ascending pharyngeal artery maintained patency of the internal carotid artery. It is important to perform vertebral angiography when there is proximal occlusion and severe stenosis of the internal carotid artery, and when the ascending pharyngeal artery has not been clearly identified as a branch from the ipsilateral external carotid artery on the common carotid angiogram.     

Treatment of aneurysm of the inferior pancreaticoduodenal artery associated with celiac axis occlusion

A case of the inferior pancreaticoduodenal artery aneurysm, associated with occlusion of the celiac axis is reported. The aneurysm seemed to be related to a high-flow state secondary to the associated occlusion of the celiac axis. The occlusion was typical of the atheromatous disease. The aneurysm was atherosclerotic in origin and was treated with resection and PTFE patching. Eighty months later an angiogram was performed, demonstrating a normal patency of the pancreaticoduodenal arcades. The treatment of these aneurysms is discussed, and the literature on this uncommon disease is reviewed.     

Spontaneous dissection of the celiac artery: a case report

Spontaneous dissection of visceral arteries is rare in the absence of concurrent dissection of the aorta, iatrogenic injury from instrumentation, or trauma. We describe a spontaneous dissection of the celiac artery that was identified by computed tomographic scan in an otherwise healthy man with acute onset abdominal pain and no identifiable causes of dissection. The patient was successfully managed medically. Although endovascular treatment or surgical intervention is the procedure of choice for complicated cases, medical management with close observation is an acceptable management strategy for stable, uncomplicated cases of spontaneous celiac artery dissection.     

Superficial temporal artery-middle cerebral artery anastomosis in a patient of temporal arteritis with internal carotid artery occlusion: a case report

Temporal arteritis is a rare systemic autoimmune disease and the arteritic process in this case of temporal arteritis involved large and medium-size arteries. Temporal arteritis with internal carotid artery (ICA) occlusion is very rare. We report a case of temporal arteritis with ICA occlusion following superficial temporal artery (STA) -middle cerebral artery (MCA) anastomosis, together with steroid therapy. A 73-year-old female presented with a headache, visual disturbance of left side, and suppression of activity. Left STA was inflammatory and overswelling. Magnetic resonance angiography (MRA) and angiography revealed occlusion of the left internal carotid artery (ICA) at the cervical portion and lowering of vascular reserve on PAO SPECT. Diagnosis as temporal arteritis was conclusive due to the clinical presentation, laboratory studies, and left temporal artery biopsy, so steroid pulse therapy was initiated. Inflammation of left STA disappeared after steroid therapy, but left ICA occlusion on angiography and lowering of vascular reserve on SPECT remained for 3 months afterwards. Because of this, STA-MCA anastomosis was performed. There were no complications after the operation and the donor artery has been patent for two years. Temporal arteritis with ICA occlusion that requires extracranial-intracranial bypass (EC-IC bypass) is very rare. STA-MCA anastomosis with steroid therapy is effective for the prevention of cerebral infarction.     

Reconstruction of the hepatic artery with the middle colic artery is feasible in distal pancreatectomy with celiac axis resection: A case report

Despite the advance of diagnostic modalities, carcinoma in the body and tail of the pancreas are commonly presented at a late stage. With unresectable lesions, long-term survival is extremely rare, and surgery remains the only curative option for pancreatic cancer. An aggressive approach by applying extended distal pancreatectomy with the resection of the celiac axis may increase the resectability and analgesic effect but great care must be taken with the arterial blood supply to the liver and stomach. Sometimes, accidental injury to the pancreatoduodenal artery compromises collateral blood flow and leads to fatal complications. Therefore, knowledge of any alternative restoration of the compromised collateral flow before surgery is essential. The present case report shows a patient with a pancreatic body cancer in whom the splenic, celiac, and common hepatic arteries were involved with the tumor, which extended almost to the root of the gastroduodenal artery. We modified the procedure by reanastomosis between the proper hepatic artery and middle colic artery without vascular graft. The postoperative course was uneventful, and the patient was discharged on post-operative day 19. The patient was immediately free of epigastric and back pain.

Aneurysm of the inferior mesenteric artery associated with occlusion of the celiac axis and superior mesenteric artery

The authors report a case of aneurysm of the inferior mesenteric artery encountered in a 38-year-old man, associated with occlusion of the celiac axis, the superior mesenteric artery and the inferior mesenteric artery distal to the aneurysm. All three arteries were revascularized. In spite of failure in the bypass of the superior mesenteric artery, the patient remained symptom free until his demise four years later, from a probable myocardial infarction. Only 11 cases of aneurysms of the inferior mesenteric artery have been reported in the literature. The causes, diagnosis and treatment of these uncommon lesions are discussed. When occlusion of the celiac axis is associated with that of the superior mesenteric artery, a complete mesenteric revascularization should be attempted whenever possible.     

Pancreaticoduodenectomy for common bile duct cancer in a patient with situs inversus totalis: a case report

We describe the first case of successfully performed pancreaticoduodenectomy to treat common bile duct cancer in a patient with situs inversus totalis. A 65-year-old man was admitted to our hospital with the working diagnosis of obstructive jaundice. He had a history of cholecystectomy, and situs inversus totalis had been diagnosed at that time in another hospital. Preoperative work-ups with ultrasonography, computed tomography, and percutaneous cholangiography were followed by drainage lead to the diagnosis of common hepatic artery arising from the superior mesenteric artery. He underwent curative pancreaticoduodenectomy without complications. The postoperative course was uneventful, and he was discharged on postoperative day 29. He is doing well, with no evidence of recurrence 40 months after surgery. Deliberately performed preoperative imaging studies, especially selective angiography, were essential for the surgical resection of bile duct cancer in this patient with situs inversus totalis.
