The prevalence of chronic diseases is very high among the elderly population. Such conditions may lengthen the hospital stay in surgical units. A history of high blood pressure is one of the most frequent ones.Objetives: Analyze if the average stay of known hypertensive patients admitted to Vascular Surgery area differs from the average stay of non-hypertensive patients. We analyzed those with any kind of medical decompensation.Descriptive analysis of patients admitted to the Vascular Surgery Department who suffered some type of medical decompensation and needed the intervention of Internal Medicine, Cardiology and/or Nephrology. The average stay of two groups, patients with known and documented hypertension, and patients with no history of hypertension, were calculated.From March 2011 to March 2015 198 consultations were made from the Vascular Surgery Service to an assigned team of professionals of Internal Medicine, Cardiology and Nephrology. The average stay was 20.2 days.Of these 198 patients evaluated, 159 (80.3%) had a documented history of hypertension. The average stay of the first subgroup was 21.4 days. The average stay of non-hypertensive group decompensated patients was 15.5 days.Four out of five patients admitted in Vascular Surgery have a history of hypertension. Their average stay is higher than the set of non hypertensive patients. Althought there are other parameters to consider, this study suggest that High Blood Pressure could be one of the main factor that rise the average stay in Vascular Surgery. Regular control of patients with a history of High Blood Pressure in Vascular Surgery Area by Internal Medicine, Cardiology and/or Nephrology should be considered as a must.
