Spontaneous Thrombosis of a Ruptured Deep Femoral Artery Aneurysm / 日本心臓血管外科学会雑誌

We report a rare case of spontaneous thrombosis of a ruptured deep femoral artery aneurysm. An 85-year-old man presented two days after onset of acute swelling and pain in the left groin. Computed tomography demonstrated rupture of a deep femoral artery aneurysm and thrombosis of the aneurysm. After 1 month of observation, surgical intervention was performed as the local pain persisted. Opening of the aneurysm sac confirmed that thrombosis was complete. Simple ligation and drainage of the aneurysmal sac was performed. His postoperative course was uneventful.

Carotid Reconstruction for Cerebral Ischemia in Aortitis Syndrome Combined with Ulcerative Colitis / 日本心臓血管外科学会雑誌

We report a case of an overlapping ulcerative colitis and aortitis syndrome. A 28-year-old woman with ulcerative colitis in the region from the rectum to the sigmoid colon developed left anterior cervical pain. A cervical contrast-enhanced computed tomography and an arch aortography showed diffuse narrowing of the left common carotid artery and segmental stenosis of the left subclavian artery involving the orifice of the vertebral artery, which defined the diagnosis as aortitis syndrome. HLA was positive for BW 52, which is frequently found in patient with this type of overlapping syndrome. Treatment with prednisolone was begun at an initial dose of 20mg/day, with gradual tapering to 5mg/day at 11 months later, when her symptoms had subsided and laboratory findings of inflammation had disappeared. One year later, she became apathetic in mental activity, and had a poor memory. She also complained of numbness on the left side of her face. Angiography confirmed the progression of the left common carotid narrowing causing the deterioration of her cerebral ischemic symptom. A saphenous vein bypass graft was placed between the right subclavian artery and the left common carotid artery. The postoperative course was uneventful and she had complete symptomatic relief and recovered active ordinary life. Postoperative angiography revealed the well functioning bypass graft.

A Case of Chronic Contained Rupture of Abdominal Aortic Aneurysm Resulting from Spinal Caries / 日本心臓血管外科学会雑誌

We report a case of a chronic contained rupture of abdominal aortic aneurysm associated with spinal caries. A giant retroperitoneal mass with bony destruction of the anterior bodies of thoracic and lumber vertebrae was detected on computed tomography in a 72-year-old woman. The patient was asymptomatic but had a history of spinal tuberculosis complicated with cold abcess 44 years earlier. Magnetic resonance imaging suggested the presence of a paravertebral retroperitoneal abscess or organized hematoma. Surgery was performed through median laparotomy and an aortotomy revealed a punched-out defect, 17mm×17mm in size, in the posterior wall of the abdominal aorta, and the large cavity of an aneurysm with an organized thrombus was observed through the defect. The abdominal aorta and common iliac arteries were replaced with a bifurcated graft. The punched-out defect was closed with the anterior wall of the aorta for the purpose of isolating the prosthesis from the aneurysm. The postoperative course was uneventful and there were no signs of prolonged inflammatory reactions. In this case, it was considered that chronic contained rupture of the abdominal aortic aneurysm resulted from spinal tuberculous osteomyelitis eroding into the aorta.

Fate of the Communicated False Lumen Following Surgical Treatment for Aortic Dissection / 日本心臓血管外科学会雑誌

The purpose of this study was to estimate the postoperative growth of untreated segments of the dissected aorta with non-thrombotic communicating false lumen, and also to evaluate the clinical outcome in relation to the aortic enlargement after surgery. Nineteen patients who underwent surgical treatment of aortic dissection were studied with enhanced CT scans and angiograms during the postoperative follow-up period. In Stanford type A patients, mean aortic dilatation rate calculated at the segment showing maximal dilatation was 5.1mm/year during 13-82 months (average, 41 months) after surgery, as a sequela of enlargement of the false lumen. Differences in the aortic dilatation rates between the different segments of the aorta were observed and these were per annum 4.8mm in the ascending aorta, 5.4mm in the transverse aortic arch, 4.3mm in the proximal descending aorta, 2.7mm in the distal descending aorta and 2.4mm in the abdominal aorta. In all patients, major communications were detected at the perianastomotic sites on angiography. In Stanford type B patients, false lumens with small communications were observed to show gradual thrombotic occlusion, but no significant aortic dilatation was detected during the follow-up period (13-70 months, average: 44 months), except three cases of sudden death who had major communications. Nine late events related to dissection, consisting of 4 sudden deaths suspected to be due to aortic rupture, 2 intestinal necroses and 3 cerebral infarctions, occured in 6 patients (32%), among which three patients had undergone arterial fenestration, one of whom had double barrel anastomosis. In the remaining two, major leakages were recognized at distal aortic anastomotic sites on postoperative angiography. The results of this study, we stress the importance of periodic check-ups using enhanced CT scan and if necessary, angiography after surgery of the patients having communicating false lumen. Early detection of progressive aneurysm formation and timely surgical reintervention can yield a good prognosis.
