From April 1981 to December 1988, a total of 23 patients were operated upon for the repair of an aneurysm of the descending thoracic aorta with a tridodecylmethylammonium chloride (TDMAC)-heparin-impregnated shunt. There were 20 men and 3 women. The ages ranged from 29 to 72 years with a mean of 52.3 years. The major pathological change of the aortic wall was medial cystic necrosis in 19 patients and atherosclerosis in 4. Among them, only 6 patients underwent elective surgery, while 17 patients underwent emergency operations with the surgical indication being shock in 4, oliguria in 3, persistence of chest pain in 2, massive hemoptysis in 1, rapid size progression of the aneurysm in 3, and impending rupture of the aneurysm in 4. During surgery, the aortic cross-clamping time ranged from 40 to 76 minutes with a mean of 54 minutes. Hospital death was limited to 2 patients with a mortality rate of 8.7%. Postoperative complications were noted in 5 patients, cerebrovascular accidents in 4 and transient paraparesis in 1. However, the clinical conditions recovered before those patients were discharged. The follow-up period ranged from 4 to 84 months with a mean of 32.3 months. Except for 1 patient who died of anaphylactic shock due to drug allergy, the other 20 survivors had an apparent improvement of their clinical status and life quality.

From 1984 to 1993, 48 thoracoabdominal aortic aneurysm resections were performed. The patient age ranged from 21 to 79 years (mean: 65.5 years), and the extent of the aneurysms were as follows: type I (most of descending and upper abdominal), 17 cases; type II (most of descending and most of abdominal), 3 cases; type III (distal descending and upper abdominal), 20 cases; and type IV (most or the entire abdominal aorta), 8 cases. Ten patients presented with ruptured aneurysms, 1 with hemoptysis, 20 with pain, and 20 with no symptoms. Operation was performed using simple aortic cross-clamping in 18 patients, distal perfusion via Gott shunt in 6, and heparinless left-heart bypass (Biomedicus pump) in 24. Intercostal or lumbar vessels were reimplanted into the graft in 13 patients. Aortic cross-clamp time was 25 to 115 minutes (mean: 49.6 minutes). Four of 10 patients (40%) with ruptured aneurysms and 3 of 38 (8%) patients with non-ruptured aneurysms died. Serious complications included paraparesis in 2 patients (5%), renal failure requiring dialysis in 2 (5%), stroke in 1 (2%), bleeding in 5 (12%), intraoperative cardiac arrest in 3 (7%), sepsis in 1 (2%), prolonged ventilation (longer than 3 days) in 11 (27%), and wound dehiscence in 2 (5%). Thoracoabdominal aneurysm resection remains a challenging problem but can be performed with acceptable risk in selected patients. Distal heparinless perfusion without a heat exchanger may help reduce the risk of paraplegia and renal failure.

We retrospectively reviewed all patients with a final diagnosis of spontaneous thoracic aortic dissection treated at Linkou Chang Gung Memorial Hospital between January 1989 and December 1994. There were a total of 109 patients with a mean age of 55 +/- 11 years ranging from 19 to 88 years. The male-to-female ratio was 2 to 1 (73 to 36). There was a predilection to present during the colder months, with 69% seen between September 1 and February 28 and only 31% during the warmer half of the year. In most patients, hypertension (85%) was the major predisposing factor with another 7% having Marfan syndrome. The remaining 8% had no obvious underlying disease except for one patient who had an atrial septum defect. Presenting chief complaints in order of frequency included: anterior chest pain 58.7% (64/109), back pain 19.2% (21/109), abdominal pain 10.1% (11/109), consciousness change 3.7% (4/109), neck pain 2.7% (3/109), paraparesis 2.7% (3/109), dyspnea 1.8% (2/109), and hemoptysis 0.9% (1/109). The diagnostic breakdown revealed 46% to be type A (50/109) and 54% type B (59/109). A total of 26 (24%) patients died in hospital (16% were type A and 8% were type B). (Type A included all proximal dissections and those distal dissections that extend retrograde to involve the arch and ascending aorta; Type B refers to the other distal dissections without proximal extension; proposed by Daily et al.) Thoracic aortic dissection remains an important concern in patients with a history of hypertension. Patients seem particularly susceptible during cold weather months. The average age of our patients was only 55 years and 24% of them died during hospitalization. Earlier identification and more aggressive antihypertensive treatment is required.

A case of watershed infarction in the spinal cord is reported. The patient underwent bronchial artery embolization for control of massive hemoptysis. The bronchial arteriogram was carefully examined and focused on blood supply to the spinal cord prior to embolization. Acute paraparesis followed the embolization procedure even though there was no visible spinal supply on the arteriogram. Magnetic resonance imaging showed a hyperintensity lesion over the watershed region which is located at the central portion of the upper thoracic cord. This case is reported to emphasize the significant role which angiographically invisible small vessels can play in the blood supply to the spinal cord. The vascular system of the spinal cord and the prevention of spinal cord ischemia secondary to embolization are further discussed here.

We report here on an uncommon case of metastatic choriocarcinoma to the lung, brain and lumbar spine. A 33-year-old woman was admitted to the pulmonary department with headache, dyspnea and hemoptysis. There was a history of cesarean section due to intrauterine fetal death at 37-weeks gestation and this occurred 2 weeks before admission to the pulmonary department. The radiological studies revealed a nodular lung mass with hypervascularity in the left upper lobe and also a brain parenchymal lesion in the parietal lobe with marginal bleeding and surrounding edema. She underwent embolization for the lung lesion, which was suspected to be an arteriovenous malformation according to the pulmonary arteriogram. Approximately 10 days after discharge from the pulmonary department, she was readmitted due to back pain and progressive paraparesis. The neuroradiological studies revealed a hypervascular tumor occupying the entire L3 vertebral body and pedicle, and the tumor extended to the epidural area. She underwent embolization of the hypervascular lesion of the lumbar spine, and after which injection of polymethylmethacrylate in the L3 vertebral body, total laminectomy of L3, subtotal removal of the epidural mass and screw fixation of L2 and L4 were performed. The result of biopsy was a choriocarcinoma.
