Karbase, a Danish register for vascular surgery is presented with data from four years experience. The register consists of 65 variables centered on risk factors, the perioperative course as well as follow-up information. During the four-year period 1989-1992 a total of 4902 admissions were registered in 3810 patients. Surgery was performed during 4005 admissions. Output data from Karbase is presented with results on survival and postoperative complications, related to preoperative risk factors. The incidence of surgical wound infections was 3.9%, with a significant reduction during the years (p = 0.004). Karbase is now used by all vascular surgical units in Denmark. We conclude that the establishment of a continuous registration has been beneficial to the department. We have achieved valid data on treatment, outcome and complications in relation to individual risk factors. In the future the use of Karbase will be extended with the aim of further quality development, locally as well as nation wide.
Anastomotic pseudoaneurysms continue to be a late complication of vascular surgery, particularly following prosthetic graft procedures. The purpose of this study was to investigate if a previously reported increase in interval between the original operation and the development of pseudoaneurysm was still valid.
We reviewed the records of 76 patients who presented with 90 femoral aneurysms. The median age was 69 years (range: 39-83). The commonest previous vascular surgery was a aortofemoral bypass in 61 cases.
The interval between the original operation and the repair of the pseudoaneurysms was 9 years (range 1 month to 26 years).
This study confirms the previously noted trend of an increasing time to aneurysm formation from 3 years before 1975, 5 years between 1976 and 1980, and 6 years between 1981 and 1990.
True arteriosclerotic aneurysms of the femoral artery are rare but they are dangerous lesions that may thrombose, embolise or rupture. They are often bilateral and frequently the patient has other aneurysms in the abdominal aortic or popliteal artery. True femoral aneurysms were originally classified by Cutler and Darling in 1973 as type 1 and type 2 according to their relationship to the common femoral bifurcation. Case reports of isolated superficial and profunda femoral artery aneurysms have been published, but these are exceedingly rare although isolated aneurysms of the profunda femoris artery may be more common in Denmark. True femoral artery aneurysms are attributed to weakening of the arterial wall due to atherosclerosis. True femoral artery aneurysms are relatively rare and are found in elderly smoking men. Aortic aneurysms are approximately 10 times more common. Distal embolization occurs in 0-26% of cases. Acute thrombosis occurs in around 15% of cases. Rupture is uncommon and varies between 10% and 14%. Aneurysmal dilatation of the profunda femoris artery is uncommon and occurs in only 1% to 2.6% of all femoral artery aneurysms. Individualized operative approaches are based on aneurysmal involvement of the superficial femoral or profunda femoris arteries, as well as the presence or absence of coexisting extremity occlusive disease. Aneurysm excision and interposition or bypass graft reconstruction are favored over direct end-to-end reanastomosis.
In a surgical varicose vein practice 509 patients who had suffered recurrent varicose veins following surgery in other institutions were traced. The causes of recurrences were identified in a retrospective analysis and related to the source of primary treatment: in hospital treatment (n = 290), surgical practice (n = 56) or another varicose vein specialist (n = 104). A significant difference was noted between the three institutions in the use of saphenofemoral resection (78%, 63% and 97%) as well as greater saphenous vein stripping (44%, 14% and 0%). Lack of or insufficiently performed saphenofemoral surgery were identified as contributing to saphenofemoral insufficiency in 40% and 43% of patients primarily treated in hospital and in surgical practice, respectively, but only in 14% of those treated by a varicose vein specialist (p

The national medical journals in Denmark, Norway, and Sweden publish selected papers from the other journals in their original languages. We wanted to know how well Scandinavian general practitioners understand their neighbour languages and English, today the "lingua franca" in medical publishing.
111 doctors (36 Norwegians, 32 Danes, 43 Swedes) completed a questionnaire in which they rated their own subjective understanding of Danish, Norwegian, Swedish, and English on a five point Likert scale.
The Norwegian doctors rated their understanding of Danish significantly higher than Swedish (p
To evaluate the outcome of treatment of femoral pseudoaneurysms in drug addicts.
The records of eight patients undergoing vascular surgery for femoral pseudoaneurysms from substance abuse identified from a vascular database were reviewed.
Were good in four out of five patients who had a primary vascular reconstruction. Two out of two patients who had a triple ligation of their aneurysms had claudication postoperatively. One patient presenting with thrombosis had a hip-exarticulation following an unsuccessful thrombectomi. No death occurred in this series.
Revascularisation at the time of resection of the pseudoaneurysm offers better prospects for limb function.
To assess outcomes after treatment for asymptomatic abdominal aortic aneurysm (AAA) in Denmark in a period when both open surgery (OR) and endoluminal repair (EVAR) have been routine procedures.
We performed a retrospective nationwide cohort study of patients treated for asymptomatic AAA between 2007 and 2010. Data on demographics, procedural data, perioperative complications, length of stay (LOS), 30-day reinterventions and readmissions, late aneurysm and procedure-related complications and mortality were obtained from the Danish Vascular Registry and the Danish National Patient Register.
525 EVAR and 1176 OR for asymptomatic AAA were identified. LOS was shorter after EVAR than OR (4 vs. 7 days, p
Problem Based Learning (PBL) has not yet been instituted systematically at medical schools in Denmark. We therefore introduced the method in a 10th term course in internal medicine and surgery, eighteen months before graduation, and evaluated the experience after two terms with a total of 93 students and 15 tutors. Compared with traditional education such as bed-side clinics and lectures etc., PBL was the preferred method by 67% of the students, while 28% found the methods equally good and only 2% discredited PBL. The main advantage of PBL was ascribed to motivation and activation, the students finding themselves as being part of the problem-solving situation. The tutors estimated PBL highly when teaching clinical coping strategies, stressing the need for a realistic and appropriate setting. This experience supports the decision to introduce PBL throughout the new medical curriculum in Copenhagen.
During the period 1 March 1987 to 31 December 1988, current registration of all vascular surgical operations in the Department of Vascular Surgery RK, Rigshospitalet, was undertaken employing a PC-based programme (DANOP-DATA). A total of 1,898 primary vascular surgical operations were performed on 1,335 patients. During the entire period, 48 (2.5%) patients with wound infection were registered. In half of these, the infection was superficial and in the remainder the infection was deep. Comparison between 1987 and 1988 revealed a non-significant tendency towards a lower incidence of infection in 1988. Significantly more wound infections were found after non-sterile operations (p = 0.005). Significantly more deep infections were found on employing synthetic vascular prostheses (p less than 0.00001) and with inguinal incisions (less than 0.05). No significant connection could be found with age, duration of preoperative hospitalization, duration of operation and the degree of planning of the operation. The authors find that computer-based monitoring of the surgical activity is a good which renders current assessment and analysis of the pattern of complications possible. The authors did not find that DANOP-DATA was sufficient for registration in a special department for vascular surgery and a programmel (KARBASE) has been developed which is more suitable for this purpose.
Atherosclerotic aneurysms of the deep femoral artery are very rare. We report the first 2 published Scandinavian cases. Both were present in elderly smoking men. They presented with acute local pain, swelling and circulatory collapse. Ultrasonography and angiography demonstrated femoral aneurysm but it was only at operation that the relation to the deep femoral artery was established. Simple ligation of the deep femoral artery was performed in one case. The other patient had a 6 mm PTFE graft interpositioned. Both made an uneventful recovery.
